Answer:

7. V= LWH

V= 3/4 x 3/4 x 3/4

V= 27/64 yd cubed

8. V = LWH

V= 10 1/2 x 16 1/2 x 6

V= 1039 1/2 ft cubed

9. Box A:

V=LWH

V=4 x 2 1/2 x 1/2

V= 5 ft cubed

Box B:

V = LWH

V=2 x 1 1/2 x 1 1/2

V= 4 1/2 ft cubed

So box A has a greater volume since 5 is greater than 4 1/2

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. $64 = 2^{(3x - 6)}$

What is the difference in length between a 11/4 inch button and a 3/8 inch button

Nutka1998 [239]

Answer:

$\frac{19}{8}$

Step-by-step explanation:

First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.

Then, cross-multiply. 11 × 8 = 88, so $\frac{11}{4}$ becomes $\frac{88}{32}$ . 3 × 4 = 12, so $\frac{3}{8}$ becomes $\frac{12}{32}$ .
