Black_prince [1.1K]

Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:

Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.

Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.

The red car can travel farther on 1 gallon of gas.

Is my answer right? I don’t really know this subject very well
melomori [17]

First let's review how to find the surface area of a rectangular prism. Since the opposite faces have the same area, we just need to find one of each pair of faces and multiply the result by 2.

One face in each pairs adds up to 6*4+2*4+2*6=24+8+12=44

Now we just need to multiply this by 2!

44*2=88 cm^2

I really hope my explanation helped, if there are any more question about this please ask me in the comments I will answer them.

James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be
Deffense [45]

Answer:

8.0%

Step-by-step explanation:

We have been given that James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be $76.57.

First of all, we will find the amount paid for the year using the monthly rate by multiplying $76.57 by 12 (1 year = 12 months).

\text{Amount paid for the year using the monthly rate}=\$76.57\times 12

\text{Amount paid for the year using the monthly rate}=\$918.84

Now, we will use percent change formula.

\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100

\text{Percent change}=\frac{\$918.84-\$850.80}{\$850.80}\times 100

\text{Percent change}=\frac{\$68.04}{\$850.80}\times 100

\text{Percent change}=0.0799717912552891\times 100

\text{Percent change}=7.99717912552891\%

\text{Percent change}\approx 8.0\%

Therefore, Mr. Harmon is paying 8.0% more for the year using the monthly rate.
