Colin is buying dirt to fill a garden bed that is a 9 ft by 16 ft rectangle. If he wants to fill it to a depth of 4 in., how many cubic yards of dirt does he need? If dirt costs $25 per yd3, how much will the project cost? (Hint: 1yd3=27 ft3).
Answers
Find the volume of the rectangular prism.
V = lwh
V = (9)(16)(4)
V = 756 ft^3
Convert to cubic yards:
1 ft^3 = 0.037037037 yd^3
756 * 0.037037037 = 28
So there are 28 cubic yards of dirt he needs.
Multiply this to 25 to find the total cost of the dirt:
28 * 25 = 700
So the project will cost $700

x=2 y=-1 what you do is you put them in y=mx+b form then you graph to find intercept.
How do you work out the problem 84 divided by4
Answers
so basically, the answer is 21 because 4 goes into 8, 2 times then you subtract 8-8, you'll get 0, bring down the four, 4 goes into, 1 time, subtract 4-4 and it equals 0, so you should get 21

The number 6 is halfway between 2.8 and...? the number 6 is halfway between -12 and...?
Answers
if 6 is halfway between 2.8 and x, then the distance from 2.8 to 6 is 1/2 the distance from 2.8 to something find the distance
6-2.8=3.2 1/2 distance=3.2 multiply by 2 to find whole distance 3.2 times 2=6.4 add 2.8+whole distance=2.8+6.4=9.2
6 is halfway between 2.8 and 9.2
6 is halfwa between -12 and something find distance 6-(-12)=6+12=18 1/2 distance=18 times 2 18*2=36 add -12+36=24
6 is halfway between -12 and 24
blanks are 6 is halfway betwen 2.8 and 9.2 6 is halfway betwen -12 and 24
