40 * 10.5 * w = 6510
420 w = 6510
w = 15.5 ft

Well, since we know (or should know) that cubic feet is found by LxWxH. We take 6510/ 10.5=620 then take the 620/ 40= 15.5. Thus your width is equal to 15.5ft

Find the slope of the line passing through the points (-5,6) and (-5,-5)
Leviafan [203]

Hi there! :) :D

Step-by-step explanation:

SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

\frac{(-5)-6}{(-5)-(-5)}=\frac{-11}{0}

<u><em>Undefined.</em></u>

<u><em>Therefore, the slope is -11/0</em></u>

<u><em>Final answer is -11/0</em></u>

Hope this helps!

Thanks!

Have a nice day! :)

:D

How to solve the function 4y+x=12
Sidana [21]
First you rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Second you solve it by using the formula of a straight line drawn on Cartesian coordinate system in which “y” is the vet risk axis and “x” the horizontal axis.

Whole page for 81! Good luck!
OLEGan [10]

Answer:

Prime number: A prime number has factor of only 1 and itself.

Ex: 3: 1 and 3 are the only ways to compose 3.

A whole number that has factors other than 1 and itself is called a composite number.

Ex: 8: the factors of 8 include 1,2,4,8

Circle 5,7,2,19,3,11

Box 18,20,22,16,15,30,26,38,45,10,21,6,14

To determine the prime factorization of a number, you must break down a number into its factors. (im not sure?)

Continute until all of the factors are (im not sure)

Prime factorization is written exponential form (im not quite sure)

30= 2x3x5

30= 2^1 3^1 5^1

24=2 × 2 × 2 × 3

24= 2^3 x 3

sorry idrk if they are all right
