Best to look up the formula for the surface area of a sphere and then find it:

A = 4πr^2, where r is the radius of the sphere. Then,

A = 4π(15 in)^2 = 4(3.14)(225 in^2) = 2826 in^2 (answer)

This is represented by the formula given in the lower left.

(a^3+a^2b/5a)(25/3b+3a)

zheka24 [161]

Answer:

$\frac{5a}{3}$

Step-by-step explanation:

The given expression is;

$(\frac{a^3+a^2b}{5a})(\frac{25}{3b+3a} )$

Factorize;

$(\frac{a^2(a+b)}{5a})(\frac{25}{3(b+a)} )$

Cancel out the common factors;

$(\frac{a(1)}{1})(\frac{5}{3(1)} )$

Simplify;

$\frac{5a}{3}$

38% of what is 152? Show work

marusya05 [52]

Take that certain number we are looking for as 'n'

38% ⇒ 0.38

0.38n = 152

Divide by 0.38

0.38n = 152
/0.38 /0.38

n = 400

So 38% of 400 is 152.

How kany doulutions does this equation have 25 - 4x=15-3x+10-x

natima [27]

Since it's a one-variable equation, it has only one solution:

25 - 4x = 15 - 3x + 10 - x

25 - 4x + x = 15 - 3x + 10

25 - 3x = 15 - 3x + 10

- 3x = 15 - 3x + 10 - 25

- 3x = 15 - 3x - 15

- 3x + 3x = 15 - 15

0 = 15 - 15

0 = 0

Hope it helped,
