The answer is 18.

Show your work: You first need to find 25% of 80. To do that you need to remember that percent means per one hundred. Knowing this you need to do 25 divided by one hundred. This equals 0.25. Now to find the answer you will need to multiply both 0.25 and 80 to find 25% of 80. This will equal 20.
Now you will need to do the same with 10% of 20. 10 divided by 100 = 0.1 and times that by 20 = 2.
That will be how many boys are wearing ear plugs. To get the girls, all you will need is to subtract 2 from 20 = 18.
That’s why there is 18 girls wearing ear plugs.

Given the definitions of f (x) and g(x) below, find the value of (g • f)(9).
Stells [14]

Answer:

  (g·f)(9) = 496

Step-by-step explanation:

One way to do this is to find the values of g(9) and f(9).

  g(9) = (3x -1)x +14 = (3(9) -1)(9) +14 = 26(9) +14 = 248

  f(9) = -(9) +11 = 2

Then ...

  (g·f)(9) = g(9)·f(9) = 248·2

  (g·f)(9) = 496

It takes two apples to make an apple pie. If a chef bought nine apples, the last pie
defon

Hey!

-------------------------------------------------

If a chef bought 9 apples and each pie takes 2 apples then all we have to do is divide.

9 / 2 = 4.5

4 full pies can be made with 9 apples.

4 x 2 = 8 (apples were used to make 4 pies.)

9 - 8 = 1 (apple remaining)

If one pie needs 2 apples, subtract.

2 - 1 = 1 (pies the chef needs to make the last one)

-------------------------------------------------

Answer: The last pie would need 1 more apple.

-------------------------------------------------
