The average is found by adding all the temperatures together, then dividing by the number of days.
Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.
The total for the first four days was : 56 + 60 + 79 + 70 = 265
The fifth day is 315 - 265 = 50 degrees.
Lets get started :)
Diameter = 2.5 ft
Radius =

a) The Circumference formula of a circle is given in the picture below, we can plug-in the given information
C = 2

(1.25) or 2.5
≈ 7.85 ft (we can leave the answer in terms of pi {

})
b) We divide the total number of distance the tire will travel by the circumference to find how many times the tire will roll
(I have used the value in feet because we found the circumference in feet units and notice that I took the value of circumference to be 2.5

instead of 7.85, to increase accuracy)
672.2
The tire will rotate
672 times (a tire cannot roll a decimal times, so we take to the nearest whole number) to travel 1 mile
Answer:-2=-2 (b)

3
Step-by-step explanation:
IT SHOULD KEEP THE SAME PROPORTION AS 1/10.
For each dollar earned one tenth is saved or 1/10 and for the $52,000, the saved money is 52000/10 = $5,200
