the volume of the rectangular prism driveway is simply length * width * height.
now, there are 12 inches in 1 foot, therefore 4 inches is really 4/12 feet or namely 1/3.
so the volume or how much concrete will be needed is just (162)(6)(1/3) ft³.
.20x=35
x=$175 total money to start
175-35(money she gave to Bill)=140 left
140/2=$70 spent 70 on books and has $70 left.
15. The answer would be B, because: When x = 2, y = 2*2+3 = 7, and so on, and so forth.
16. The answer would also be B, because: When x = 11, y = 10(11-1) = 100, and so on, and so forth.
Hope this helped! c:
1. Two $5 bills have the same value as one $10 bill
2. Four $5 bills have the same value as one $20 bill
3. Twenty $5 bills have the same value as one $100 bill
3.4 hours. The efficiency of a worker is the amount of work divided by time needed. The efficiency of Sanjay alone is 500/6, and the efficiency of Felipe alone is 500/8. When they work together, their combined efficiency is 500/6+500/8=3500/24. Therefore, they need 500/(3500/24)=24/7=3.4 hours.
