Part A) means that we have to find a composition of functions A and m
A(m(t))=π(9t)²=9πt²
part B)
A(m(t))=9πt²
A(m(2))=9*3.14*(2)²=113.04
(5+1+1)*2 + 5*5*5*(1+5)*4 = 3014
Rooms = 5*5 = 25
Cats per room = 5 + 5*5 = 30
All cats legs = 25*30*4 = 3000
All humans = 1+1+5 = 7
All humans legs = 7*2 = 14
All legs = 3000 + 14 = 3014
The way you convert is by dividing your answer to the question by 1,2or how many they are talking about . Once you do that you will get your answer which may be a decimal and the you put the unit kg for kilograms. so that will be the answer to the problem.

Question: What is 2.5% of 19520?
Answer: 488
Answer:
There are 240 boys.
Step-by-step explanation:
There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.
Let <em>b</em> represent the number of boys and <em>g</em> girls.
Since the ratio is 5:3, we can write that:

And since the total number of students is 384:

From the first equation, cross-multiply:

Solve for <em>g: </em>

<em />
Substitute:

Simplify:

Solve for <em>b: </em>
<em />
<em />
<em />
In conclusion, 240 of the total students are boys.
