We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.

Let us assume that 7 is n% of 30. So we can set a proportion as:

$\frac{n}{100}=\frac{7}{30}$

Let us solve for n.

$\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100$

$n=\frac{7}{3}\cdot 10$

$n=\frac{70}{3}$

$n=23.333$

Therefore, 7 is $23.333\%$ of 30.

Which expression can be used to find the surface area of the following square pyramid?

telo118 [61]

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4. Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides. Thus, the total slant surface area is 4(10 units^2), or 40 units^2.

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.
