The roof is made up of two mirred right triangles which are congruent. We can find the width by finding the width of one of the triangles then doubling the answer to get the width of the entire roof.

We are given that the slope (rise over run) is 5/12 which means that for every 5 feet of height there is 12 feet of width. We can use this ratio to find the width of one triangle given the height of 8 by setting up the following proportion:

5/12 = 8/x

Solve for x by cross multiplying:

5x = (12)(8)

x = (12)(8)/5

x = 19.2 feet

Multiply by 2 to get the entire width:

(19.2)(2) = 38.4 feet

The answer is 38.4 feet

Harlamova29_29 [7]

Answer:

x = -35/22, or 1.5909090...

Step-by-step explanation:

Solving for x will be easy enough, but cross multiplication won't be necessary as that's only applicable when division is involved:

35 = 2x - 24x

35 = -22x

x = -35/22, or 1.5909090...

SOMEONE HELP PLS I NEED SOMEONE TO EXPLAIN STEP BY STEP IM SO CONFUSED
Minchanka [31]

Answer:

x = ln (33)

     ------------

      3 ln (2)

Step-by-step explanation:

2 ^ (3x) = 33

Take the ln of each side

ln ( 2 ^ (3x)) = ln  33

We know  ln ( a^b) = b ln a

3x ln (2) = ln 33

3x = ln 33

       ------------

           ln 2

Divide each side by 3

x = ln (33)

     ------------

      3 ln (2)

Use the original price and the markdown to find the retail price.
babymother [125]

Answer:

$53.20

Step-by-step explanation:

First, you need to find 24% of $70.

Change the percent to a decimal.

24% to .24.

Multiply that times 70.

.24 x 70 = 16.8

This will be the amount of money taken off the original price, so you will subtract it from the $70.

70 - 16.8 = 53.2

Therefore, the retail price is $53.20
