Answer:

It would be 5 foot 9 inches shorter.

Step-by-step explanation:

You need to subtract 7 foot 3 inches from 13 feet. To make this simpler, you can turn the feet into inches. So multiply the 7 be 12, and add 3. 87 inches. Now you need to turn the 13 feet into inches, so multiply the 13 by 12 (because there is 12 inches in 1 foot) That gives you 156. Now subtract,

156-87.


This gives you 69 inches. All you need to do know is convert that into feet. And that gives you 5 feet and 9 inches. So, the board is 5 feet and 9 inches shorter that the long board.

And to check this, you can simply add 5 feet 9 inches to 7 feet 3 inches. Which gives you 13 feet in total.

Amanda [17]
If all were dimes, the value would be $3.30. Brendan has $2.85 more than that. Each quarter that replaces a dime increases the value by $0.15, so Brendan must have $2.85/$0.15 = 19 quarters.

Brendan has 14 dimes and 19 quarters.

yulyashka [42]
Surface area of a square pyramid is the area of the base + 4 times the area of one of the slanted sides.
Area of base = side length * side length
Area of side = (1/2) * side length * slant height
Don't forget that you have to multiply the area of the side by 4!

Step 1: 12 x 12 = 144
Step 2: 12 x 20 = 240 divided by 2 = 120
Step 3: 144 + 120 x 4

Solve the proportion 40/z+1 = 15/6
vovangra [49]

Answer:

<h2>z = 15</h2>

Step-by-step explanation:

\frac{40}{z + 1}  =  \frac{15}{6}  \\

<u>Cross multiply </u>

That's

15(z + 1) = 40(6) \\ 15z + 15 = 240

<u>Send 15 to the right side of the equation</u>

15z = 240 - 15 \\ 15z = 225

Divide both sides by 15

\frac{15z}{15}  =  \frac{225}{15}  \\

We have the final answer as

<h3>z = 15</h3>

Hope this helps you
