7 hours + 6 hours + 6 hours
=19 hours
12 minutes + 46 minutes + 53 minutes
=111 minutes
=1 hour 51 minutes
19 hours + 1 hour and 51 minutes is 20 hours and 51 minutes. This is the total time.
Average time = total time/number of deliveries
(20 and 51/60) divided by 3
=6.95 hours
= 6 hours and 57 minutes
The answer is 4/15, because we have to get the denominaters to be the same, so the LCM of 5 and 15 is 15, so 15/5 is 3 and 4*3 is 12. Now, its 12/15-8/15 which is 4/15. Hope this helps!
Answer:
or -0.625
Step-by-step explanation:
The slope formula is as shown:

We can have A = (
,
) and B = (
,
).
We can hence plug in the values into the formula to get
.
As we simplify, the negatives on the top row cancel out to give us an addition sign instead and we add them.

This is middle school??? AinT no way
I’m pretty sure the answer is E. X is a linear function. Z is a cubed root function. W is a quadratic function and Y is exponential
