Step-by-step explanation:

You can set this up in an algebraic equation:
.09x=5 which translates to 9% times a variable or unknown number equals 5
Divide both sides by .09 which turns to 55.5
Multiply by .36 to find 36% of that number which equals 20

The area of the regular hexagon is 10.4 in.2. a regular hexagon has side lengths of 2 inches and an area of 10.4 inches squared.

VARVARA [1.3K]

Answer:

(b) 1.7 in

Step-by-step explanation:

The area of a regular polygon in terms of perimeter and apothem is given by the formula ...

A = 1/2Pa

For a hexagon, the perimeter is 6 times the side length, so this becomes ...

A = 1/2(6s)a = 3sa . . . . . for side length 's' and apothem 'a'

Solving for the apothem, we find ...

a = A/(3s)

For the given values of area and side length the apothem is ...

a = 10.4/(3·2) = 1.733... ≈ 1.7 . . . inches

The apothem, rounded to tenths, is 1.7 inches.

A car travels 348 miles on 12 gallons of gas dominic used 8 gallons on a trip how far did the car travel

Cloud [144]

Answer:

We can start by figuring out how much he traveled per gallon. To do so all we need to do is divide the amount of miles he drove by the gallons it took him to drive that distance (348/12). This comes out to 29 miles. THerefore he drives 29 miles per gallon of gasoline.

Now to find how far he traveled with 8 gallons we need to multiply 29 times 8 (miles per gallon times how many gallons he used)

Your answer is 232
