I was told that the answer to this is -7 but I don't understand how to get there.

Answer:

The answer to your question is: - 7

Step-by-step explanation:

3125 = (- 1 - 18t) ⁵/³

(3125)³ = ( -1 - 18t)⁵

(3125)³/⁵ = - 1 - 18t

125 = - 1 - 18t

125 + 1 = - 18t

126 = - 18t

t = 126 / -18

t = -7

3125³ = 3.0518 x 10¹⁰

$\sqrt[5]{3.0518 x 10¹⁰}$ = 125

Please help how do i find the area of the shape?

Orlov [11]

Answer:

Do not listen to the other answer! Here is how you solve that.

Step-by-step explanation:

For the semicircle, here is the formula for area: $A= \frac{1}{2}(\pi r^2)$

For the triangle, here is the formula for area: $A=\frac{1}{2}(bh)$

Then, add.

So,

Triangle:

$A=\frac{1}{2}(9*12)$

$A=54$

Semicircle:

$A=\frac{1}{2}(\pi 6^2)$

$A=18\pi$

Your answer is $Area = 54 + 18\pi$
