You probably meant that the team ran

laps around the track.
Length of running track = 34 miles.
Since the team ran

times around the track, in order to find the total number of miles we multiply the length of track by

.
Therefore, total number of miles run by team will be equal to:

Rounding of to nearest mile, the team ran 91 miles around the track.
To find the number of years between 1844 to 2015 you have to subtract.
Lets say that x is the # of years in between 1844 and 2015
Then we have:

After doing the subtraction using a calculator or a pencil and paper, you get that:

So 171 years have passed from 1844 to reach to 2015.
Answer:
0.96 or .96
Step-by-step explanation:
40 divided by 100 = 0.4 to change the percent to a decimal
and multiply 2.40 to 0.4, 0.4 times 2.40 is 0.96 or .96
Answer:
The common difference d in the given sequence is -17
Step-by-step explanation:
We need to find the common difference d of the following sequence 9 -8 -25 -42 -59
We have a₁ = 9
and a₂ = -8
The formula used is: 
By putting values we can find the value of d
We have n=2, a₂ = -8, a₁ = 9 and we need to find d

So, the common difference d in the given sequence is -17
