Answer:
how r u suppose to give 30 if it is only for 15
Step-by-step explanation:
Charles can do the whole job in an hour, Bill can do 1/2 of the job in an hour, and Bob does 1/3 of the job in an hour. Therefore, they do a total of 1+1/2+1/3=11/6 of the job in an hour, meaning it takes them 6/11 of an hour. This is 6/11*60=360/11 minutes, or approximately 33 minutes.
Answer: No real solution
Step-by-step explanation:
To find the area of a trapezoid it (top length + bottom length)/ 2 times height
Top length is 9
Bottom length is 19
(9+19)/2 x height = area
Area=168
14x height=168
Height =12
Answer:
$5,674.30
Step-by-step explanation:
Use the Compound Amount formula:
A = P(1 + r/n)^(n*t), where r = APR as a decimal fraction = 0.1499
and n = 12 (compounded monthly).
Then A = $2,000(1 + 0.1499/12) )^(7*12)
= $2,000(1 + 0.0125)^84
= $2,000(1.0125)^84 = $2,000(2.837) = $5,674.30
