Answer:
40 mph
Step-by-step explanation:
We assume "outbound" refers to the trip <em>to the lake</em>. The ratio of speeds is inversely proportional to the ratio of times, so ...
outbound speed : inbound speed = 4 : 3
These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...
4×10 mph = 40 mph
Paul's average speed on the outbound trip was 40 mph.
___
The distance to the lake was 120 mi.
1 x 10^-8 or .1 nanometer (nm)
Answer:
ABC is not a right triangle
Step-by-step explanation:
The computation is shown below:
AC is
= Perimeter - (AB + BC)
= 22 - (8+5)
= 22 - 13
= 9
Now
= 9^2 + 13^2
= 81 +169
= 250
And, the perimeter is
= 22^2
= 484
Since the amount are not equivalent therefore ABC is not a right triangle
Given:
The values of input and outputs are given
Output is increasing by 9 for the increase in x values.
