Answer:

1. She could use 7 hours and 11 dollars per hour.

2. $77 (7x11)

3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.

Answer:

Step-by-step explanation:

If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation

10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off

Find the area of a rectangle that is 16 3/5in. by 8 9/10
Alenkinab [10]
<h2>Greetings!</h2>

Answer:

Area is 147.74

Step-by-step explanation:

You need to recall that the equation for the area of a rectangle is:

Length * Width = area

So 16 3/5 * 8 9/10 = area

Rearrange so the whole numbers are being multiplied and the fractions are too:

We need to make the denominator same, this can be done by simply multiplying 3/5 by 2:

3/5 * 2 = 6/10

Now the two numbers can be written as 16.6 and 8.9.

Multiply both numbers by 10:

166 * 89 = 14774

Then divide this by 100 (two lots of division by 10)

14774 ÷ 1000 = 147.74

So the area of the rectangle is 147.74!

drek231 [11]

Answer:

Step-by-step explanation:

Base on my own understanding what should be done is that three stacks will not work, because it wont be a symmetric arrangement and also one will be left out. So, two stacks of five each would be better and easy to carry. But the stacks should be arranged in such a manner that the lengths will be parallel to each other and not in-line which would increase the length making it comparatively very long. its easier to hold a (2*8.5,11,2*5=17,11,17) compact box, because it will be easy to carry a long and not heavy.
