Answer:
12
Step-by-step explanation:
8 1-and-a-half blocks would be 12 blocks, and so 12/17, because 12 blocks in 17 mins., so you divide 12 by 17 to get ---- blocks per minute, which is 12/17 as a fraction, or approx. 0.705882353 blocks per minute.
We have been given that professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot.
Therefore, we can find the slope as:
Therefore, the recommended slope for a sewer pipe is
Answer:
1 5/12 or 12/7
Step-by-step explanation:
slope is y2-y1 over x2-x1
so 4-(-8) over 0-(-7)
4-(-8) = 12
0-(-7) = 7
slope be 12/7 or 1 5/12
I dont understand that but ok?
