Determine operating cost per mile. Choose the right answer.
SVETLANKA909090 [29]

Answer: $0.1428/mi or about 14 cents per mile

Steps:

While the cost of car = $5,000.00 is not an operating cost, the annual decrease of value is. So, given that the market value after 1 year = $3,800, the value loss is 5000-3800=$1200 for the year.

Add cost of gas and oil = $750.00, Repairs/Maintenance = $250.00, Insurance = $300.00, to get $2500 total operating cost.

The cost per mile is $2500/17500 miles = $0.1428/mi or about 14 cents per mile

I need help getting the answer for the 1st question
Karo-lina-s [1.5K]
If we have two similar triangles:
Triangle 1 (base 1 , height1).
Triangle 2 (base 2, height 2)
Then:

base 1 /height 1=base 2 /height 2

Data:
base 1=0.2 m
height 1= 1 m
base 2= 8 m
height 2=x

We calculate the height of the tower:
base 1 /height 1=base 2 /height 2
0.2 m / 1m=8 m / x
x=(8 m * 1 m) / 0.2 m
x=8 m²/0.2 m
x=40 m

Answer. the heigth of the tower will 40 m

In the measurement of 67.93 cm, which digit is estimated? click on the estimated digit
scoundrel [369]
When it comes to measurement, the most accurate estimate would be the whole number. A ruler has calibrated marks. It would be easy to locate 25. But when it is located between 25 to 26, you would have to estimate the decimal points. Generally, calibration marks are up to the tenths digit. For further digits, that would only an estimation. So, the estimated digit in this problem is 3 in the hundredths place.
