The inequality 2|x - 3| + 6 > 10 has the solution set:
x < 1 or x > 5
To solve the inequality 2|x - 3| + 6 > 10, we need to isolate the absolute value expression |x - 3|.
We can do this by subtracting 6 from both sides of the inequality:
2|x - 3| > 4
Then we can divide both sides by 2:
|x - 3| > 2
Now we need to consider two cases, one where x - 3 is positive, and another where it is negative:
When x - 3 is positive, the inequality |x - 3| > 2 becomes:
x - 3 > 2
Solving for x gives:
x > 5
When x - 3 is negative, the inequality |x - 3| > 2 becomes:
-(x - 3) > 2
Solving for x gives:
x < 1
Therefore, the solution set for the inequality 2|x - 3| + 6 > 10 is:
x < 1 or x > 5

The approximate mass of a hydrogen atom is grams. The mass
of a single lead atom is approximately grams. How many times
heavier is a lead atom than a hydrogen atom?
A lead atom is 200 times heavier than a hydrogen atom.
To determine how many times heavier a lead atom is compared to a hydrogen atom, we can calculate the ratio of their masses.
Mass of hydrogen = 1.7 × 10⁻²⁴ grams
Mass of lead atom = 3.4 × 10⁻²² grams
To find the ratio of their masses, we divide the mass of the lead atom by the mass of the hydrogen atom:
Ratio = 3.4 × 10⁻²² / 1.7 × 10⁻²⁴
= (3.4 / 1.7)× 10⁻²² / 10⁻²⁴
= 2×10²
= 200
Therefore, a lead atom is 200 times heavier than a hydrogen atom.

A friend has a 80% average before the final exam for a course. The score includes everything but the final, which counts for 15% of the course grade. What is the best course grade your friend can earn? What is the minimum score would your friend need on the final to earn a 75% for the course?
Your friend would need to score at least 46.67% on the final exam to earn a 75% for the course.
Since the final exam counts for 15% of the course grade, the weighted average can be calculated as follows:
Weighted average = (0.85 × 80%) + (0.15 × final exam score)
If we assume that your friend wants to get the highest possible grade, then they would need to get a perfect score on the final exam, which would be 100%.
Plugging this into the equation above, we get:
Weighted average = (0.85 × 80%) + (0.15 × 100%) = 83%
Therefore, the best course grade your friend can earn is 83%.
We can set up an equation where x is the minimum score needed on the final exam:
Weighted average = (0.85 × 80%) + (0.15 × x) = 75%
Simplifying this equation, we get:
0.85 × 80% + 0.15x = 75%
68% + 0.15x = 75%
0.15x = 7%
x = 46.67%
Therefore, your friend would need to score at least 46.67% on the final exam to earn a 75% for the course.

Part A: At her current rate, the distance Amy can ride her bike within 12 minutes is A. 1.6 miles.
Part B: Sebastian can ride his bike for C: 7.5 miles in 1 hour.
Part C: The time it will take for one to wait is B: Amy will have to wait 1.5 minutes for Sebastian.
How to determine the distance a rider can ride his bike?Part A:
To find the distance Amy can ride her bike in 12 minutes, we set up a proportion based on her current rate.
Amy's rate: 4 miles / 30 minutes = x miles / 12 minutes
Cross-multiplying:
30x = 4 * 12
30x = 48
Dividing both sides by 30:
x = 48 / 30
x ≈ 1.6
So, Amy can ride her bike at 1.6 miles in 12 minutes.
Part B:
To find the distance Sebastian can ride his bike in 1 hour, convert the time to minutes first.
1 hour = 60 minutes
Sebastian's rate: 3 miles / 24 minutes = x miles / 60 minutes
Cross-multiplying:
24x = 3 * 60
24x = 180
Dividing both sides by 24:
x = 180 / 24
x ≈ 7.5
Therefore, Sebastian can ride his bike at 7.5 miles in 1 hour.
Part C:
Amy's home to Park = 3 miles,
Park to Sebastian's home = 3 miles.
Amy's rate = 4 miles in 30 minutes, equivalent to 1 mile in 7.5 minutes.
Sebastian's rate = 3 miles in 24 minutes, equivalent to 1 mile in 8 minutes.
Then, we estimate the time it takes for each to cover a distance of 3 miles.
Amy:
Time = Distance / Rate = 3 miles / (2/15 miles/minute)
= 3 * (15/2) minutes
= 22.5 minutes
Sebastian:
Time = Distance / Rate = 3 miles / (1/8 miles/minute)
= 3 * 8 minutes
= 24 minutes
Since Amy= 22.5 mins and Sebastian takes 24 mins,
24 - 22.5 = 1.5
Hence, Amy will have to wait 1.5 minutes for Sebastian.

Mean, Fractiles, median, and mode are called the measures of central tendency
The mean monthly income is $3300, the median monthly income is $3000, there is no mode, and the range of the monthly income is $3000.
To find the mean, median, mode, and range of the monthly incomes, we'll perform the following calculations:
Mean:
The mean is calculated by summing all the values and dividing by the total number of values.
Mean = (2000 + 2500 + 3000 + 4000 + 5000) / 5
Mean = 16500 / 5
Mean = 3300
The mean monthly income is $3300.
Median:
The median is the middle value when the data is arranged in ascending order. In this case, since we have an odd number of values, the median is the middle value.
Arranging the incomes in ascending order: $2000, $2500, $3000, $4000, $5000
The median monthly income is $3000.
Mode:
The mode is the value(s) that appear most frequently in the data. In this case, there is no value that appears more than once, so there is no mode.
The data has no mode.
Range:
The range is calculated by subtracting the minimum value from the maximum value.
Range = Maximum Value - Minimum Value
Range = $5000 - $2000
Range = $3000
The range of the monthly income is $3000.

Lily is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 30 represents the number of flowers that bloomed, where s is the number of seeds she planted. The function s(w) = 40w represents the number of seeds she plants per week, where w represents the number of weeks.
Part A: Write a composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks. (4 points)
Part B: What are the units of measurement for the composite function in Part A? (2 points)
Part C: Evaluate the composite function in Part A for 35 weeks. (4 points)
Step-by-step explanation:
Part A:
To find the composite function, we need to plug in the expression for s(w) into f(s):
f(s(w)) = 2s(w) + 30
= 2(40w) + 30
= 80w + 30
Therefore, the composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks is f(s(w)) = 80w + 30.
Part B:
The units of measurement for the function f(s(w)) are the same as the units of measurement for f(s) and s(w). From the given information, we know that s(w) represents the number of seeds planted per week and f(s) represents the number of flowers bloomed based on the number of seeds planted. Thus, the units of measurement for f(s(w)) are "flowers" per week.
Part C:
To evaluate the composite function f(s(w)) for 35 weeks, we need to substitute w = 35 into the expression we found in Part A:
f(s(35)) = 80(35) + 30
= 2,830
Therefore, Lily can expect 2,830 flowers to bloom after planting 40 seeds per week for 35 weeks.

150°
95°
55°
Answer:
Measure of angle HEK is: 85°.
Step-by-step explanation:
Given that point E is the center of the protractor, we have:
angle HEJ = 55° (EH points to 55 degrees)
angle JEK = 30° (EK points to 30 degrees)
Since angle HEJ and angle JEK meets at a point E, then we can find angle HEK by summing up the two angles:
angle HEK = angle HEJ + angle JEK
angle HEK = 55° + 30°
angle HEK = 85°

The producer of a weight-loss pill advertises that people who use the pill lose, after one week, an average (mean) of 1.8 pounds with a standard deviation of 1.02 pounds. In a recent study, a group of 45 people who used this pill were interviewed. The study revealed that these people lost a mean of 1.73 pounds after one week.
If the producer's claim is correct, what is the probability that the mean weight loss after one week on this pill for a random sample of 45 individuals will be 1.73 pounds or less?
Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
The probability that the mean weight loss after one week on the pill for a random sample of 45 individuals will be 1.73 pounds or less is approximately 0.3231, or 32.31%.
How to find the probability that the mean weight loss after one week on this pill for a random sample of 45 individuals will be 1.73 pounds or lessCalculating the standard error of the mean (SE) using the formula:
SE = σ / sqrt(n)
where σ is the standard deviation and n is the sample size.
SE = 1.02 / sqrt(45) ≈ 0.1522
We can calculate the z-score using the formula:
z = (x - μ) / SE
where x is the observed mean and μ is the claimed mean.
z = (1.73 - 1.8) / 0.1522 ≈ -0.4582
Using a standard normal distribution table or a calculator, we find that the probability is approximately 0.3231.
Therefore, the probability that the mean weight loss after one week on the pill for a random sample of 45 individuals will be 1.73 pounds or less is approximately 0.3231, or 32.31%.

¿Por qué, aunque un trinomio tenga raíz exacta en el primer y tercer término, no siempre se puede aplicar el método de adición y sustracción para convertirlo en trinomio cuadrado perfecto?
The reason for not applying method of addition and subtraction on first and third term shown below.
The reason why the method of addition and subtraction cannot always be applied to convert a trinomial with exact roots in the first and third terms into a perfect square trinomial is because the second term may not be a perfect square or a multiple of the square root of the first term multiplied by the square root of the third term.
In order to convert a trinomial into a perfect square trinomial using the method of addition and subtraction, the coefficient of the second term must be twice the product of the square root of the first term and the square root of the third term. If this condition is not met, the trinomial cannot be transformed into a perfect square trinomial using this method.
Therefore, it is important to consider the coefficients and terms of the trinomial to determine if the method of addition and subtraction can be applied successfully.

How much longer does it take a satellite signal to reach point B than it takes to reach point E? Use 186,000 mi/sec as the speed of a satellite signal. Round your answer to the nearest hundredth. Show your process and explain your reasoning.
The satellite is in orbit above the planet's equator. Along with the point directly below it on the planet's surface, the satellite makes one complete revolution every 36 hours. How fast must it travel to complete a revolution in that time? Round your answer to the nearest whole number. Show your process and explain your reasoning.
The distance travelled by the satellite in 36 hours would be: Distance travelled in 36 hours = (21991.5 / 24) × 36 = 549787.5 miles. Now, we can find the speed of the satellite as follows: Speed of the satellite = Distance / Time = 549787.5 / (36 × 3600) ≈ 4.76 miles/sec. Hence, the speed of the satellite is approximately 4.76 miles/sec (approximately 17136 miles/hr).
1. Find the distance from the satellite to the points of tangency Solution: Firstly, we need to draw a rough diagram of the scenario to easily understand it. Consider a satellite revolving around an alien planet in a synchronous orbit 18,000 miles above its surface.
We can see that B and D are the points of tangency of the satellite signal with the planet, and C is the center of the planet. Hence, the figure will look like the following: Image Source: Synchronous Orbit - Wikimedia Commons Now, we need to find the distance from the satellite to the points of tangency.
Hence, the distance from the satellite to the points of tangency, B and D, is 61861.9 miles (approximately 61862 miles).2. Find the percentage of the planet's equator within range of the satellite's signal Solution: We can see that the planet's equator can be represented by a circle with a radius of 3500 miles. Hence, the circumference of the circle would be 2π × 3500 miles ≈ 21991.5 miles.
We know that the satellite's signal can be received directly up to a distance of 61862 miles from it. Hence, the length of the portion of the equator within range of the satellite's signal would be twice the distance from the satellite to the point of tangency, which is 2 × 61862 ≈ 123724 miles. Now, we need to find the percentage of the planet's equator within range of the satellite's signal.
Hence, we need to find the time taken for the satellite signal to reach points B and E. We can see that the distance from the satellite to point B is 61862 miles and the distance from the satellite to point E is 3500 miles. Hence, the time taken for the satellite signal to reach point B would be: Time taken to reach point B = Distance / Speed = 61862 / 186000 ≈ 0.332 seconds Now, we need to find the time taken for the satellite signal to reach point E.
Hence, the time difference between the satellite signal reaching points B and E is approximately 0.07 seconds.4. Find the speed of the satellite Solution: We know that the satellite takes 36 hours to complete one revolution around the planet along with the point directly below it on the planet's surface. Hence, we need to find the distance travelled by the satellite in 36 hours to find its speed.
We can see that the distance travelled by the satellite in one revolution is equal to the circumference of the circle with a radius of 3500 miles, which is 2π × 3500 miles ≈ 21991.5 miles. Hence, the distance travelled by the satellite in 36 hours would be: Distance travelled in 36 hours = (21991.5 / 24) × 36 = 549787.5 miles.
Now, we can find the speed of the satellite as follows: Speed of the satellite = Distance / Time = 549787.5 / (36 × 3600) ≈ 4.76 miles/sec. Hence, the speed of the satellite is approximately 4.76 miles/sec (approximately 17136 miles/hr).

Step-by-step explanation:
A minute hand travels a full revolution along a circular path in 60 minutes
The distance from the center to the tip of the minute hand = 8 cm
We can consider the movement of the minute hand as being on the circumference of a circle with radius = 8 cm
Circumference = 2π · r
= 2π · 8
= 16π
I5 minutes = 15/60 = 1/4th
So in 15 minutes the minute hand will cover only 1/4th of the full circle
Therefore distance traveled by tip of minute hand

ok, let's assume the rate is 0.075 per minute, if we convert that to percentage that'd be 0.075*100 or 7.5% per minute, so we can assume the bread is cooling off at 7.5% per minute after coming out of the oven at 340°F and we need it at 80°F so we can slice it and put some butter on it.

On the second draw, there will be only 51 cards to choose from, rather than 52 because you have already taken out a card. Therefore, you only have a 25/51 chance of drawing a red card compared to the 26/52 or 1/2 chance on the first draw.
Answer is 25/51.
x-1 is a factor of which of the following?
1.x²+x-2
11.2x2–5x+3
O Neither
OI only
O II only
OI and II
The term (x - 1) is a factor of both of the given polynomials:
x² + x - 2
2x² - 5x + 3
How to check if x - 1 is a factor?
If (x - a) is a factor of a polynomial p(x), then x = a is a zero of the polynomial, which means that:
p(a) =0.
So, if x - 1 is a factor of any of the given polynomials, then we need to evaluate them in x = 1 and check if we get zero.
a) x² + x - 2
Evaluate it in x = 1.
1² + 1 - 2 = 0
it is zero, so (x - 1) is a factor.
b) 2x² - 5x + 3
Evaluating this in x = 1.
2*1² - 5*1 + 3
2 - 5 + 3 = 0
(x - 1) is a factor.
Then the correct option is the last one, it is a factor of both polynomials.

The proof that the value of x is 38° is shown below
How to show that the value of x is 38°From the question, we have the following parameters that can be used in our computation:
ABDE is a parallelogram.
The measure of the angle opposite the vertex x is
Angle = 180 - 68
Evaluate the like terms
So, we have
Angle = 112
Also, we have
B = 68
AB = AC
So, we have
y = 180 - 68 - 68
y = 44
Using the above as a guide, we have the following:
x + 44 = 82
So, we have
x = 82 - 44
Evaluate
x = 38
Hence, we have shown that the value of x is 38°

manager states that all 80 crates can be packed in a 2m x 2m area e store room. (Assume that the height of the store room is adequate stacked crates) y if this statement is correct. Show all your calculations.
Note that based on the volume calculations, the manager's statement is NOT correct. The given area of 2m × 2m is insufficient to store all 80 crates.
How is this so ?To verify if the manager's statement is correct, we need to derive the volume of each crate and the total volume required to store all 80 crates.
Volume = Length × Width × Height
Recall that
Length (L) = 690 mm
Width (W) = 445 mm
Height (H) = 180 mm
Thus, the Volume of one crate is
Volume = 690 mm × 445 mm × 180 mm
Converting mm to meters we have,
Volume = (690 / 1000) × (445 / 1000) × (180 / 1000)
= 0.690 × 0.445 × 0.180
= 0.055269 m³
Next , we calculate the total volume required for 80 crates as
Total Volume = Volume of one crate × Number of crates
= 0.055269 m³ × 80
= 4.42152 m³
Recall that the manager stated that all 80 crates can be packed in a 2m × 2m area in the store room.
Since area of store room is
Area = 2 m × 2 m
Area = 4 m²
Comparing the total volume required (4.380208 m³) with the available area (4 m²), we see that the volume exceeds the area. Tus, the manager's statement is incorrect.
