By Pythagoras  AB^2 = 12^2 - 6^2 =  108

AB = sqrt 108 = 10.39 to nearest hundredth

The perpendicular from M to DC will be parallel and equal to AB so  it = 10.39.

Also  AB^2 = CB * DB

108  =  6 * DB
DB = 108/6  = 18
so DC = 18-6 = 12

MD^2 = (1/2*12)^2 + 108  =   144

so MD = 12

Write a story that can be represented by the equation y=x+1/4x
makvit [3.9K]

This question is pretty much asking: Write a story that can be represented by the equation y=1.25x.

So, how about this one: Lily's mom tells Lily to clean up her toys. Lily puts toys away at a rate of one toy per every 1.25 seconds.

That's it, simple as that :P

(Sorry if it wasn't too helpful.)

A prism has a square base with a side length of 4 1 2 4 1 2 feet. The height of the prism is 6 feet. What is the volume of the p
dusya [7]

We have been given that a prism has a square base with a side length of 4 1/2 feet. The height of the prism is 6 feet. We are asked to find the volume of the prism.

We know that volume of prism is base area times height.

\text{Area of base}=\text{Area of square}=\text{Side length}^2

\text{Area of base}=(4\frac{1}{2})^2

\text{Area of base}=(\frac{9}{2})^2

\text{Area of base}=\frac{9^2}{2^2}

\text{Area of base}=\frac{81}{4}

\text{Volume of prism}=\frac{81}{4}\times 6

\text{Volume of prism}=\frac{81}{2}\times 3

\text{Volume of prism}=\frac{243}{2}

\text{Volume of prism}=121\frac{1}{2}

Therefore, the volume of prism is 121\frac{1}{2}\text{ ft}^3 and option D is the correct choice.

PLEASE HELP ME WITH THIS 17 points!! PLEASEEEE IM BEGGING YOU!!!
slega [8]

Answer:

x = 2

Step-by-step explanation:

Step 1: Convert to math

5x + 1 = 3x + 5

Step 2: Solve for <em>x</em>

  1. Subtract 4x on both sides: 2x + 1 = 5
  2. Subtract 1 on both sides: 2x = 4
  3. Divide both sides by 2: x = 2

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

5(2) + 1 = 3(2) + 5

10 + 1 = 6 + 5

11 = 11
