Answer:

24 hours

Step-by-step explanation:

To answer this question, you just have to divide the total amount Mary is trying to earn, $132, by the unit rate, $5.50 per hour:

132 / 5.50 = 24

So, Mari needs to work 24 hours to earn $132

Hope this helps :)

How you know a fraction is less than 1/2
nikitadnepr [17]

The fraction will continue to be the same numerator "1". However the denominator will be a greater number. Such as 4. Then you will know it is broken into more peices (as being a greater number). These pieces will automatically be a smaller fraction.

So, in order to know if a fraction is less then 1/2, it will have a greater denominator.

hope this helps :)

Justin wants to use 376 ft of fencing to fence off the greatest possible rectangular area for a garden. what dimensions should h
Rina8888 [55]
Let the length be x and the width be y
the perimeter of the rectangle will be:
2x+2y=376
thus 
y=188-x
thus the area will be:
A(x)=x(188-x)
A(x)=188x-x^2

For maximum Area A'(x)=0
from Area we shall have
A'(x)=188-2x=0
solving for x we get:
x=94
thus the width will be:
188-94=94
thus for maximum area the length=94 ft and width=94 ft
Area=94*94=8836 ft^2
thus the answer is:
<span>c. 94 x 94; 8836ft </span>
