Answer:
-3y-8 1/2
Step-by-step explanation:
1/4y-13/4y=-12/4y=-3y
1.5+2-12=-8.5 or 8 1/2
you need 628 square feet of sand.
<h3>How many cubic feets of sand are needed?</h3>
Here we need to find the volume of the sand needed.
The volume filled with sand will be a cylinder of diameter of 20ft, and a height of 2 inches.
First, the radius is half of the diameter, then:
R = 20ft/2 =10ft
Remember that:
1ft= 12in
Then:
R = 10ft = 10*(12 in) = 120 in
And remember that the volume of a cylinder of radius R and height H is:

Where pi = 3.14
Then we have:

To get that in feets, we need to divide by 12 squared, then:

So you need 628 square feet of sand.

Answer:
lance
Step-by-step explanation:
because they get 7 point each and he has more
1/8 + 3(1/4) + 2(1/2) + 5/8 + 3/4 + 7/8 + 1 =
1/8 + 3/4 + 1 + 5/8 + 3/4 + 7/8 + 1 =
13/8 + 6/4 + 2 =
13/8 + 12/8 + 16/8 =
41/8 =
5 1/8 inches <==
