Answer: 40 minutes
Step-by-step explanation: The first thing you want to do is divide 24 by 3 to find how much each dancer rested per hour. In other words, find the unit rate. 24 divided by 3 is 8. Next, take the 8 and multiply it by 5, since we are trying to find how much each dancer rested in 5 hours. 8 x 5 = 40. So each contestant rested for 40 minutes.

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
A The expressions are only equivalent for x = 4 and x = 6.
B The expressions are only equivalent when evaluated with even values.
C The expressions have equivalent values for any value of x.
D The expressions should have been evaluated with one odd value and one even value.
E When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
F The expressions have equivalent values if x = 8.
Answer:
7x + 4 = 3x + 5 + 4x - 1
7x + 4 = 7x + 4

Find the missing dimension of the cylinder. Round your answer to the nearest whole number.
Volume = 3785 cm3
Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31
61
square root of 61

Answer:
It seems to just mess around with the positive and negatives.
Step-by-step explanation:
When you flip an object by the x axis, the x part of the coordinates (x, y) would become negative, or if already negative, positive. Try it yourself, by taking point be, and counting down to the line of the x axis. Remember the number down you counted, and count that same number down from the x axis. That is mirroring a point.
After arguing for two weeks, Nora convinced her parents to have her birthday party at FlyZone trampoline park. As soon as she gets there, Nora spends time practicing flips on the trampolines. Then, she spends 1/2 of an hour eating birthday cake with her friends. In all, Nora spends 1 3/4 hours at FlyZone. Which equation can you use to find the amount of time Nora practices flips?
Solve this equation for (t) to find the amount of time Nora practices flips
To write a fraction.
Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.

Step-by-step explanation:
Area of a right triangle: 1/2*b*h
base (b): 12
height (h): 4
A = 1/2*b*h
A = 1/2*12*4

you find the price of 1 avocado which you find by dividing 10 by 6 which is 1.66 then multiply that by 3 which is 4.98 then round to the nearest whole number and get 5. (also a little trick you can do is realize that 3 is half of 6, so the price of 3 should be half of the price of 10 which is 5.)

A bucket of sand weighed 3 pounds. Then Eloise added another 20 ounces of sand to the bucket.
How much does the bucket of sand weigh now?
4 1/ 4 lb
4 1/2 lb
5 1/4 lb
5 1/2 lb
The weight of the bucket of sand after Eloise added 20 ounces of sand is 4.25 pounds
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we need to convert 20 ounces to pounds.
There are 16 ounces in 1 pound, so 20 ounces is equal to:
20/16 = 5/4 = 1.25 pounds
Therefore, the weight of the bucket of sand after Eloise added 20 ounces of sand is:
3 + 1.25 = 4.25 pounds
Thus,
The weight of the bucket of sand after Eloise added 20 ounces of sand is 4.25 pounds

Answer:
The scale is 2/3. The short side would be 100 and the big side would be 200.
Step-by-step explanation:
If the big side is double the small side, then the math is simple. You just find 2/3 of each side. The big side would be 300 because it is double the small side, which is already stated as 150.

In your indoor garden, 50% of seeds sprout. What is the experimental probability that at least one of your next three seeds sprout?
Using the binomial distribution, it is found that there is a 0.875 = 87.5% probability that at least one of your next three seeds sprout.
For each seed, there are only two possible outcomes, either it sprouts, or it does not. The probability of a seed sprouting is independent of any other seed, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
50% of seeds sprout, hence p = 0.5.There are 3 seeds, hence n = 3.The probability that at least one of your next three seeds sprouts is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]
Then:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.125 = 0.875[/tex]
0.875 = 87.5% probability that at least one of your next three seeds sprout.

A hyena can run one over four of a mile in 22.5 seconds. At this rate, which equation can be used to determine how fast a hyena runs in miles per hour? (5 points)
one-fourth mile over twenty-two point five seconds = 40 miles per hour
twenty-two point five seconds over one-fourth mile = 40 miles per hour
one-fourth mile over twenty-two point five seconds = 90 miles per hour
twenty-two point five seconds over one-fourth mile = 90 miles per hour
I basically just need to know which equation it is. I know its 40 miles per hour.
Answer:
1/4 mile over 22.5 seconds.
Step-by-step explanation:
Because you are calculating miles over hours, not hours over miles, miles will be on top and hours will be on bottom. Hope this helps!
