and the formula for that is A=lw
so you have a length of 15.5.     
Put those in and you get 170.5=15.5w.
you divide 170.5 by 15.5 and get 11.
the Width is 11.

Line equations from point/slope
babunello [35]

Answer:

The answer is

y =  \frac{1}{4} x + 3

Step-by-step explanation:

Plug in and solve the equation. We are trying to find the y-intercept:

y=  \frac{1}{4}x  + b \\  2 =  \frac{1}{4} ( - 4) + b \\ 2 =  - 1 + b \\  \frac{ + 1 =  + 1  \:  \:  \:  \:  \:  \:  \:  \: }{3 = b}

We found the y-intercept, so now we plug it in it's right full spot in the formula.

y =  \frac{1}{4} x + 3

What is the answer to this question? Please Help.
Arte-miy333 [17]

Answer:

x = 2, y= 3

Step-by-step explanation:

y = -2x+7

y = 5x-7

Since the equations are both equal to y, set them equal to each other

-2x+7 = 5x-7

Add 2x to each side

-2x+7 +2x= 5x+2x-7

7 = 7x -7

Add 7 to each side

7+7 = 7x

14 = 7x

Divide by 7

14/7 = 7x/7

2 = x

Now find y

y = 5x-7

y = 5*2 -7

y = 10-7

y =3

Priya's rectangular prism measures inches by inches by 2 inch.
dedylja [7]

The number of cubes with edge length ⅕ inch that will fit in the prism is: 1,920 cubes

<h3>Volume of a Rectangular Prism</h3>

Volume of a rectangular prism = length × width × height

<h3>Volume of a Cube</h3>

A cube has equal edge length. Therefore, the volume of a cube = a³, where a is the edge length.

Given the following,

Dimensions of Priya's Rectangular Prism:

2⅖ = 2.4 inches

3⅕ = 3.2 inches

2 inches

Volume of the Rectangular Prism = 2.4 × 3.2 × 2 = 15.36 in.³

Dimension of the cubes:

edge length = ⅕ inch

Volume of the cube = (⅕)³ = 0.008 in.³

The number of ⅕ inch edge cube that will fit in the prism = Volume of Prism / Volume of Cube

= 15.36/0.008 = <em>1,920 cubes </em>
