Answer:

Step-by-step explanation:

Given,

Time taken (t) = 10 - 6 = 4hrs

Water decreased (V) = 24000l - 18000l = 6000l

Now,

average rate of decrase (Avg) = V/t = 6000l/4 =1500 L/h

A regular hexagon and a rectangle have the same perimeter, P. A side of the hexagon is 4 less than the length, l, of the rectang

Genrish500 [490]

Answer:

The perimeter of the hexagon is equal to 36 units

Step-by-step explanation:

Let

x-------> the length side of the hexagon

L-----> the length of the rectangle

W-----> the width of the rectangle

we know that the perimeter of the hexagon is equal to the perimeter of the rectangle is equal to so

-------> equation A

-------> equation B

-------> equation C

Substitute equation B and equation C in equation A

Solve for L

Find the value of x

Select the equation that has the same solution as the equation below.<br> 5^(2x-5)= 125

Ahat [919]

The equation that has the same solution as $5^{(2x-5)} = 125$ is: C. $64 = 2^{(3x - 6)}$

<h3>How to Solve Equations having Exponents</h3>

To solve such, simplify the bases so that the base on the right equals the base on the left.
Then solve the equation for the variable.

Given:

$5^{(2x-5)} = 125\\\\5^{(2x-5)} = 5^3\\$

The bases will cancel out

2x - 5 = 3

Solve for x

2x = 3 + 5

2x = 8

x = 4

The solution of $5^{(2x-5)} = 125$ is 4.

Thus:

$64 = 2^{(3x - 6)}\\\\2^6 = 2^{(3x - 6)}\\\\6 = 3x - 6\\6 + 6 = 3x\\12 = 3x\\4 = x\\x = 4$

Therefore the equation that has the same solution as $5^{(2x-5)} = 125$ is: C. $64 = 2^{(3x - 6)}$
