Answer:
32 houses will have a pool
Step-by-step explanation:
40% of 80 is 32
7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x) /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/
8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/
Answer:6.15
Step-by-step explanation:
change 2.5% by dividing by 100. 2.5÷100=0.025. Then multiply 6 by 0.025. 6×0.025=0.15. Then add 0.15 to 6 for the answer. 6+0.15=6.15.
