4/5 vs. 3/5 is the fraction comparison problem that can be resolved using the same number of missing pieces approach.
The same number of missing pieces method compares the numerator of two fractions after determining the common denominator for the two fractions. Only when the denominators of the fractions are different does this method work. We can identify a common denominator of 20 and compare the numerators in option b because the denominators (4 and 3) disagree.
Consequently, 4/5 can be expressed as 16/20 and 3/5 as 12/20. When we compare the numerators, we obtain 16 > 12, meaning that 4/5 is higher than 3/5. Because they share the same denominator or have no common factor, the other possibilities cannot be solved using the same number of missing pieces technique.

to solve that multiply the denominator on the left with 8 and the one on the right with 7 to make them equivalent and do the same for the numerator so now its 76/56 so now just simplified as much as possible will be 19/14
Answer:
Take your question 6/7 + 4/8, and find a common denominator. 7 and 8 both go in to 56, so set both denominators to 56.
The question now reads 6/56 + 4/56.
Multiply the numerator by the number of times the denominator was multiplied to get to the common denominator. 8 goes into 56 7 times, and 7 goes into 56 8 times.
Therefor:
7 x 8 = 56, and 8 x 7 = 56.
Now multiply the numerator by the amount of times the denominator went into the common denominator.
8 x 6 = 48 and 7 x 4 = 28.
So 48/56 and 28/56.
We could then simplify, by dividing both sides by the same number.
12/14
7/14
Then add the numerators only.
That would give us 19/14

more than 10,000 seconds. Which friend is
correct? Explain.
Answer:
Kai is correct and Leila is incorrect. The movie is actually 10,800 seconds long.
Step-by-step explanation:
1 hour = 60 minutes
1 minute = 60 seconds
Therefore, 1 hour = 60 x 60 = 3600 seconds
So, the movie's length in seconds is:
3 hours x 3600 seconds/hour = 10,800 seconds
Leila says the movie is less than 10,000 seconds, which is not correct, since the movie is actually longer than 10,000 seconds.

If you took the amount of oil consumed in 2 months in 2013 worldwide, you could make a cube of oil that measures 10^3 meters on each side. How many cubic meters of oil is this? Do you think this would be enough to fill a pond, a lake, or an ocean?
Answer:
10^9 cubic meterslakeStep-by-step explanation:
You want to know the number of cubic meters in a cube that is 10^3 meters on each side, and whether that volume amounts to a pond, lake, or ocean.
VolumeThe volume of a cube is given by ...
V = s³
where s is the edge length.
The volume of interest is ...
V = (10³ m)³ = 10⁹ m³
The volume of oil is 10⁹ cubic meters.
LakeThe sizes of ponds and lakes vary, but we might consider a pond to be a body of water larger than about 150 square meters and less than 6 meters in depth. On the other hand, a lake will generally be larger than about 4000 square meters. An average size lake may be about 10 meters in depth.
If we put the given amount of volume in a space with a depth of 40 meters, it would cover an area of about 25 million square meters, roughly 6000 acres. That is the area of a circle about 7 km in diameter. This might be considered a medium-sized lake.
The oil would fill a medium-sized lake.
__
Additional comment
A "lake" is generally a body of water upwards of an acre in area. While an average lake in some areas is about 10 m deep, worldwide, the average is just over 40 m in depth. Some lakes are well over 20,000 acres in area.
A "pond" may be larger than a "lake", but will generally be smaller than 500 acres.

Find the avatar rate of change f(x)=3√x-1 +2; 9 ≤ x ≤ 65
Answer: To find the average rate of change of the function f(x) over the interval [9, 65], we can use the formula:
average rate of change = (f(b) - f(a)) / (b - a)
where a = 9, b = 65, f(a) = f(9) = 3√8 + 2, and f(b) = f(65) = 3√64 + 2.
Plugging in these values, we get:
average rate of change = (f(65) - f(9)) / (65 - 9)
average rate of change = (3√64 + 2 - 3√8 - 2) / 56
average rate of change = (3(4) + 2 - 3(2) - 2) / 56
average rate of change = (12 - 4) / 56
average rate of change = 8 / 56
average rate of change = 1 / 7

if the pile contains only 25 quarters but at least 50 of each other kind of coin, how many collections of 50 coins can be chosen? collections
The number of collections of 50 coins that can be chosen from this pile is: C(125, 25) = 177,100,565,136,000
This is a very large number, which shows that there are many possible collections of 50 coins that can be chosen from the pile.
If the pile contains only 25 quarters but at least 50 of each other kind of coin, then the total number of coins in the pile must be at least 50 + 50 + 50 = 150. Let's assume that there are 150 coins in the pile, including the 25 quarters.
To choose a collection of 50 coins from this pile, we need to exclude the 25 quarters and choose 25 coins from the remaining 125 coins. We can do this in C(125, 25) ways, which is the number of combinations of 25 items chosen from a set of 125 items.
Therefore, the number of collections of 50 coins that can be chosen from this pile is:

To find the number of collections of 50 coins that can be chosen, we will consider the given conditions:
The pile contains only 25 quarters.
There are at least 50 of each other kind of coin (pennies, nickels, and dimes).
Now, let's break this down step by step:
Determine the minimum number of coins from each kind required to make a collection of 50 coins.
- 25 quarters (as it's the maximum available)
- The remaining 25 coins must be a combination of pennies, nickels, and dimes.
Find the different combinations of pennies, nickels, and dimes that can be chosen to make a collection of 50 coins.
- We need 25 more coins, so we can divide them into three groups:
a) Pennies (P)
b) Nickels (N)
c) Dimes (D)
Calculate the combinations for the remaining 25 coins.
- Using the formula for combinations with repetitions: C(n+r-1, r) = C(n-1, r-1)
Where n is the number of types of coins (3) and r is the number of remaining coins (25)
- C(3+25-1, 25) = C(27, 25) = 27! / (25! * 2!) = 351.

the population of weights for men attending a local health club is normally distributed with a mean of 166-lbs and a standard deviation of 26-lbs. an elevator in the health club is limited to 33 occupants, but it will be overloaded if the total weight is in excess of 5940-lbs. assume that there are 33 men in the elevator. what is the average weight beyond which the elevator would be considered overloaded? average weight
This means that if the average weight of the men in the elevator is more than 180 lbs, the elevator would be overloaded.
To determine the average weight beyond which the elevator would be considered overloaded, we can follow these steps:
Find the total weight limit for 33 occupants: 5940 lbs.
Divide the total weight limit by the number of occupants to find the average weight per person: 5940 / 33 = 180 lbs.
Now, we need to find the difference between the average weight per person (180 lbs) and the mean weight of the population (166 lbs): 180 - 166 = 14 lbs.
Since we have the difference and the standard deviation (26 lbs), we can now calculate the Z-score:
Z = (difference) / (standard deviation) = 14 / 26 ≈ 0.54.
The average weight beyond which the elevator would be considered overloaded is 180 lbs.
The corresponding Z-score for this weight is approximately 0.54.

Here we have
A circle with centre O(2, 3) contains the point A(5, 11).
Since point A(5, 11) is located on the circle with center O(2, 3), use the distance formula to determine whether A is actually on the circle.
The distance between two points (x₁, y₁) and (x₂, y₂) is given by:
=> d = √(x₂ - x₁)² + (y₂ - y₁)²)
Using this formula, the distance between O(2, 3) and A(5, 11) is:
d = √(5 - 2)² + (11 - 3)²)

The probability of selecting such a permutation is very low, only about 0.31%.
The probability of the event when we randomly select a permutation of the 26 lowercase letters of the English alphabet where 'm' immediately precedes 'n', which immediately precedes 'o' can be calculated as follows:
Firstly, we need to determine the total number of permutations of the 26 letters. Since there are 26 letters in the alphabet, there are 26! ways to arrange them.
Next, we need to determine the number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o'. To do this, we can consider 'mno' as a single unit and then there are 24! ways to arrange the 24 units (23 individual letters and 1 unit of 'mno').
However, there are 3! ways to arrange 'mno' within the unit, so we need to multiply by 3!. Therefore, the total number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o' is 24! x 3!.
Thus, the probability of randomly selecting a permutation where 'm' immediately precedes 'n', which immediately precedes 'o' is:

why would you use a trigonometric function to set-up an application problem instead of a non-trigonometric function
Trigonometric functions are used to model relationships between angles and sides of a right triangle. They are particularly useful in solving problems that involve angles, distances, heights, and lengths that are difficult to measure directly.
For example, consider a problem that involves finding the height of a building. By measuring the length of the shadow cast by the building at a particular time of day, the angle of the sun's rays can be calculated using trigonometry. Once the angle is known, the height of the building can be determined using the tangent function.
In contrast, a non-trigonometric function may not be able to model the relationship between the given quantities in such problems, and may not provide an accurate solution. Therefore, when a problem involves angles or distances that are not directly measurable, trigonometric functions are typically the best tool for setting up and solving the problem.

How to find arc PQKnowing that the arc lengths are in degrees and the total for a circle is 360 degrees then we have the equation
8x - 10 + 6x + 10x + 10 = 360
To solve the equation 8x - 10 + 6x + 10x + 10 = 360 for x, we first need to simplify the left side of the equation by combining like terms:
8x + 6x + 10x - 10 + 10 = 24x
Now the equation becomes:
24x = 360
To solve for x, we need to isolate x on one side of the equation by dividing both sides by 24:
24x/24 = 360/24
x = 15
Therefore, the solution for x is 15.

Alberto adds enough water to bring the tank back up to 15 gallons. Then he adds water-cleaning drops to the 15 gallons of water in the tank. The directions says to use 1 drop for each 1/4 gallon of water. After putting in 2/3 of the total drops needed, Alberto has to stop and answer his phone. How many drops does alberto still need to add to the water? Explain how you found your answer
If after putting in 2/3 of total-drops needed, Alberto stop and answer his phone, then the number of drops that Alberto still need to add to water is 20 drops.
The directions say to use "1 drop" for each 1/4 gallon of water, and Alberto has 15 gallons of water in the tank,
So, the "total-number" of drops needed is :
⇒ Total number of drops needed = (1 drop per 1/4 gallon) × (15 gallons) × (4 quarters per gallon),
⇒ Total number of "drops-needed" is = 60 drops,
Next, we calculate "2/3" of "total-drops" needed,
To find out how many drops Alberto has already added,
We calculate 2/3 of the "total-drops" needed,
⇒ 2/3 of total drops = (2/3) × (total number of drops needed),
⇒ 2/3 of 60 drops = (2/3) × 60 = 40 drops,
So, Alberto has already added 40 drops of water-cleaning drops,
To calculate how many drops Alberto still needs to add, we subtract drops he already added from total drops needed,
⇒ Drops still needed = (Total drops needed) - (Drops already added),
⇒ 60 drops - 40 drops = 20 drops
Therefore, Alberto still needs to add 20 drops.

To convert km/h (kilometers per hour) to m/s (meters per second), we need to divide the speed by 3.6.
Therefore, 135 km/h = (135/3.6) m/s ≈ 37.5 m/s
So, 135 km/h is approximately equal to 37.5 m/s.
1) Choose all of the common denominators of 2/3 and 7/9.
2) Choose all of the common denominators of 1/9 and 1/2
Please help me in both if you can. If not then only 1 answer is fine :). Thank you.
1) The common denominators of 2/3 and 7/9 are: 9, 18, 27, 36, 45, 54, 63, ...
2) The common denominators of 1/9 and 1/2 are: 18, 36, 54, 72, 90, 108, ...
To find the common denominators of 2/3 and 7/9, we need to find the least common multiple (LCM) of the denominators 3 and 9.
Prime factorization of 3: 3 = 3^1
Prime factorization of 9: 9 = 3^2
To find the LCM, we take the highest power of each prime factor that appears in either factorization. So, LCM(3, 9) = 3^2 = 9.
Therefore, the common denominators of 2/3 and 7/9 are all multiples of 9.
2) To find the common denominators of 1/9 and 1/2, we need to find the LCM of the denominators 9 and 2.
Prime factorization of 9: 9 = 3^2
Prime factorization of 2: 2 = 2^1
To find the LCM, we take the highest power of each prime factor that appears in either factorization. So, LCM(9, 2) = 2 x 3^2 = 18.
Therefore, the common denominators of 1/9 and 1/2 are all multiples of 18.

URGENT
Emma doesn’t have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card:
It has a 15% annual interest rate.
The interest is compounded monthly.
The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1+r/n)^nt , where P represents the initial, or principal, balance; r represents the interest rate; t represents the time in years; and n represents the number of times the interest is compounded per year.
Part A
Question
Identify the values of P, r, and n in the expression P(1+r/n)^nt based on Emma’s situation. Then substitute those values into the formula to write a simplified exponential expression in terms of time.
Replace the variables a, b, and c to write the expression.
Part B
Question
Since the card has $0 minimum payments for the first 4 years it is active, Emma wonders how much it will cost her if she doesn't pay off the $300 balance until after college. How much will she owe in 4 years?
Type the correct response in the box. Use numerals instead of words. Round your answer to the nearest dollar.
In 4 years, Emma will owe about $
.
Part C
Question
Emma also wonders how long it will take her balance of $300 to reach $450, assuming she doesn’t make any payments toward it. Write the equation to represent the situation, and solve it using the inverse relationship between exponential and logarithmic expressions.
Type the correct response in the box. Use numerals instead of words. Round your answer to the nearest tenth.
It will take about
years for Emma’s balance to reach $450.
Part D
Question
Emma notices that since her credit card balance compounds monthly, she is charged more than 15% of her initial loan amount in interest each year. She wants to know how much she would pay if the card were compounded annually at a rate of 15%. What expression could Emma use to evaluate her balance with an annual compounding interest rate?
Part E
Question
How would the situation change if the interest on Emma’s credit card were compounded annually rather than monthly, and she didn’t make any payments toward the balance?
Select the correct answer from each drop-down menu.
After 4 years, Emma would owe approximately $
for her original purchase of $300.
It would take around
years for her balance to increase from $300 to $450
Emma has a credit card with 15% annual interest compounded monthly. The exponential expression is 300(1+0.15/12)^(12*t). She owes $509 in 4 years. It's about $464. Time it will take for her balance to reach $450, which is about 5.6 years. The expression to evaluate her balance with an annual compounding interest rate is 300(1+0.15)^t = 300(1.15)^t. If the card were compounded annually, she would owe about $459 in 4 years and it would take about 6.5 years for her balance to reach $450.
P = $300 (initial balance)
r = 0.15 (annual interest rate)
n = 12 (monthly compounding)
The simplified exponential expression is
300(1+0.15/12)^(12*t)
Using the formula from Part A with t = 4
300(1+0.15/12)^(12*4) ≈ $509
Emma will owe approximately $509 in 4 years if she doesn't make any payments toward the balance.
The equation for the situation is
300(1+0.15/12)^(12*t) = 450
Taking the logarithm of both sides and solving for t:
t = log(450/300) / (12*log(1+0.15/12)) ≈ 5.6 years
It will take about 5.6 years for Emma's balance to reach $450 assuming she doesn't make any payments toward it.
The expression Emma could use to evaluate her balance with an annual compounding interest rate is
300(1+0.15)^t = 300(1.15)^t
After 4 years, Emma would owe approximately $459 for her original purchase of $300.
It would take around 6.5 years for her balance to increase from $300 to $450.
