D -e/3d + e= e, for d​

Answers

Answer 1
Answer:

Answer:

\large\boxed{d=(e^2+e)/(1-3e)}

Step-by-step explanation:

(d-e)/(3d+e)=e\n\n(d-e)/(3d+e)=(e)/(1)\qquad\text{cross multiply}\n\n(1)(d-e)=(e)(3d+e)\qquad\text{use the distributive property}\n\nd-e=3de+e^2\qquad\text{add}\ e\ \text{to both sides}\n\nd=3de+e+e^2\qquad\text{subtract}\ 3de\ \text{from both sides}\n\nd-3de=e^2+e\qquad\text{distribute}\n\nd(1-3e)=e^2+e\qquad\text{divide both sides by}\ (1-3e)\n\nd=(e^2+e)/(1-3e)

The volume of a rectangular prism is 300 ft3. If the area of the base is 12 ft2, what is its height?

Answers

The height of the rectangular prism will be 25 feet.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

The volume of a rectangularprism is 300 ft³.

If the area of the base is 12 ft².

Then the height of the rectangular prism will be

We have

V = 300 ft³

L x W = 12 ft²

Then we have

300 = 12 x H

   H = 25 feet

More about the volume of the prism link is given below.

Hey there, the formula for volume is length×base×height, the volume of a rectangular prism is 300 ft and the length and base is 12 ft, 300=12h, h=300/12=25. Therefore, the height is 25

Bryan bought two shirts for 14.50 each and a pair of shoes for 29.99. The sales tax was 6%. How much did Bryan spend?

Answers

14.50 + 29.99 = 44.49
6% = 0.06
44.49 x 0.06 = ~2.67
44.49 + 2.67 = 47.16
add 14.50 and 29.99 and then multiply by 0.06
