Haley is returning from a business trip. Her empty suitcase has a mass of 5.1 kg. Her clothes have a combined mass of 14.8 kg. Haley also wants to pack 4 gifts, each with a mass of 870 g. The airline restriction for a suitcase is a limit of 22.7 kg. Can Haley bring everything home in her suitcase? If not, how many gifts can she pack? Explain.​

Answers

Answer 1

From the calculation, she can't carry all but she can carry her suitcase with clothes in it and three out of the four gift items.

What can she pack?

We know that we have to consider the restriction that the airline has placed. We have been told that the luggage that have to be packed in this case would have to be less than 22.7 kg.

We would now have to look at all the things that Haley would need to pack so as to determine what can be packed and what can not be packed.

Total luggage  that she has to pack;

Mass of empty suitcase + mass of her clothes + mass of 4 gifts

Total luggage = 5.1 Kg + 14.8 Kg + 4(0.87) = 23.38 Kg

This implies that she can't carry all but she can carry her suitcase with clothes in it and three out of the four gift items.

how many liters each of a 50% acid solution and a 85% acid solution must be used to produce 70 liters of a 75% acid solution

Answers

To produce 70 liters of a 75% acid solution, we need to mix a 50% acid solution and an 85% acid solution in the right proportions. Let x be the number of liters of the 50% acid solution, and y be the number of liters of the 85% acid solution.

We can set up a system of two equations to represent the problem:

x + y = 70 (the total volume of the mixture is 70 liters)
0.5x + 0.85y = 0.75(70) (the total amount of acid in the mixture is 75% of 70 liters)

Simplifying the second equation, we get:

0.5x + 0.85y = 52.5

Now we can solve for x and y using the system of equations. One way to do this is to multiply the first equation by 0.5 and subtract it from the second equation:

0.5x + 0.85y = 52.5
-0.5x - 0.5y = -35
--------------------
0.35y = 17.5
y = 50

So we need 50 liters of the 85% acid solution. Substituting this value into the first equation, we get:

x + 50 = 70
x = 20

Therefore, we need 20 liters of the 50% acid solution and 50 liters of the 85% acid solution to produce 70 liters of a 75% acid solution.

Answers

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 less

Calculating 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%.

Answers

Answer:

4π cm

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

= 1/4 x 16π = 4π cm

Answers

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).

¿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?

Answers

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.

Answers

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.

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?

Answers

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.

Answers

To evaluate the expressions:

7C1:
7C1 represents the number of ways to choose 1 item from a set of 7 items without regard to order, which is known as a combination.
7C1 = 7! / (1!(7-1)!)
= 7! / (1! * 6!)
= 7 / 1
= 7

Therefore, 7C1 is equal to 7.

6P4:
6P4 represents the number of ways to arrange 4 items in a sequence from a set of 6 items, taking order into account. This is known as a permutation.
6P4 = 6! / (6-4)!

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:

Surface area of a rectangular prism = 2 [lw + wh + lh], where l, w and h are length, width and height respectively.

Surface area of big rectangular prism = 2[(6 × 6) + (6 × 7) + (6 × 7)]

                                                               = 240 m²

Surface area of smaller rectangular prism = 2[(3 × 4) + (4 × 7) + (3 × 7)]

                                                                      = 122 m²

Total area of the prism = 240 m² +  122 m²

                                      = 362 m²

Hence the surface area is 362 m².

Answer:

x-intercept = -7

y-intercept = 1

rate of change = 1.25

Step-by-step explanation:

X and Y intercept are pretty to find.

Rate of change is [tex]\frac{f(b)-f(a)}{b-a}[/tex]

So for our case it will be [tex]\frac{-0.75-(-2)}{-8-(-9)}[/tex]

The answer will be 1.25

What is 4320 minutes, in days? (Remember, there are 60 minutes in an hour and 24 hours in a day.)

Answers

There are 1440 minutes in a day (24 hours x 60 minutes = 1440 minutes).

To convert 4320 minutes to days, divide 4320 by 1440:

4320 ÷ 1440 = 3

Therefore, 4320 minutes is equivalent to 3 days.

Answer: 3 days

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.

Answers

The probability of the point being in region A is 0.5294.

The area of the entire figure can be found by adding the areas of the four triangles:

Area of entire figure

= Area of triangle ABC + Area of triangle ACD + Area of triangle ABD + Area of triangle BCD

= (1/2)(5)(3) + (1/2)(3)(4) + (1/2)(4)(3) + (1/2)(3)(4)

= 7.5 + 6 + 6 + 6

= 25.5 square inches

Similarly, the area of region A can be found by adding the areas of triangles ABC and ABD:

Area of region A

= Area of triangle ABC + Area of triangle ABD

= (1/2)(5)(3) + (1/2)(4)(3)

= 7.5 + 6

= 13.5 square inches

Therefore, the probability of the point being in region A is:

P(A) = Area of region A / Area of entire figure

P(A) = 13.5 / 25.5

P(A) = 0.5294

So the probability of the point being in region A is 0.5294.

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)

Answers

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.
