How many square inches are in 20 square feet?

2880

Step-by-step explanation:

If there is 12in. in 1ft. then we square it to turn the feet into square feet and inches into square inches. 1ft squared = 1sqft. 12in squared = 144. Multiply 20 by 144 to turn the feet into inches. Bada Bing Bada Boom.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
