Answer:
5065.1
Step-by-step explanation:
To go down the line, you need to do the 15 x 15 x 15 x 15 (15^4), in which equals 50,625. Then, 50,625 - 10 which equals 50,615. Next, 50,615 + 36 which equals <u>50,651.</u> Finally, you would need to do <em>50,651 ÷ 10. </em>Making it *<u>5065.1*</u>
Answer:
If the homeowner helps the roofer it will take 4 days to roof the house.
Step-by-step explanation:
Given that a homeowner estimates that it will take 11 days to roof his house, while a professional roofer estimates that he could roof the house in 6 days, to determine how long it will take if the homeowner helps the roofer the following calculation must be done:
1/6 + 1/11 = X
0.1666666 + 0.09090909 = X
0.25 = X
1/4 = X
Therefore, if the homeowner helps the roofer it will take 4 days to roof the house.
It would take 5 hours for all the bacteria to die. 1000 divided by 5 is 200 so 200x5=1000
32/8=4
4x9=36
