The answer will be D) 75

To find this it’s easiest to find how many animals there are per percent. So to find this you simply have to divide 30 (the number of cats) by 40 (the percent that makes up) to find the number of animals per percent.

30/40

.75

Then you multiply this by 100 to find how many animals there are total.

.75(100)

75

How do I do pre-Algebra???
Lana71 [14]

Hey there!

The main concept of pre-algebra is solving equations for variables in them.

For example, let's say you have the algebraic equation below.

x+1=3

With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.

We would subtract 1 to both sides to isolate x on one side.

x+1-1=3-1

As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.

x=3-1

x=2

Therefore, in our equation x+1=3, x would be equal to 2.

I hope this explanation helps! Have a great time here at Brainly!

The volume of this sphere is 904.32 cubic inches. What is the surface area of this sphere?
andrew-mc [135]

Answer:

A = 4 pi R^2     V = 4/3 pi R^3

A / V = 3 / R

Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in

So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2
