The total number of hours was 7 so divide $28.84 by 7 and you'll get $4.12 per hour.

Answer:

The rental cost per hour is $4.12.

Step-by-step explanation:

A painter rented a wallpaper steamer at 9 am and returned it at 4 pm.

4 pm = 16:00 pm

He rented a wallpaper steamer for the time =  16:00 - 09:00 = 7:00 hrs.

He paid for 7 hours = $28.84

Therefore, for 1 hour = 28.84 ÷ 4 = $4.12

The rental cost per hour is $4.12.

lesya692 [45]

Answer:

$5,500

Step-by-step explanation:

Let A be the amount invested at 3%, B the amount at 4%.

Total value:

1.A%2BB=8000

Interest:


Multiply eq. 1 by -3 and add to eq. 2,

-3A-3B%2B3A%2B4B=-24000%2B29500

highlight%28B=5500%29

Then from eq. 1,

A%2B5500=8000

highlight%28A=2500%29

A notebook has a perimeter of 36 inches and an area of 80 square inches. What are the dimensions of the notebook?
maw [93]
Let L be length and W be width
The perimeter of a rectangle is 2W+2L=36
Thus 2W=36-2L, W=18-L
Area of a rectangle is WL=80
Thus (18-L)(L)=80
18L-L^2=80
L^2-18L+80=0
(L-8)(L-10)
Thus L can either be 8 or 10.
Because WL=80
If L is 8, then W=10
If L is 10, then W=8
So either way, the notebook is 8 by 10

<u><em>Speed = Distance / Time</em></u>

<em>Rearranging the formula</em>

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal.  Ordered from least to greatest.

Sherbert, blue, red, and green
