Car A used 40.5 L of gasoline to travel 450 km. Car B used 18.7 L to travel 220 km. Circle the car with better fuel mileage. Justify your answer by calculating each car’s L/100 km rate. Show your work.

Answers

Answer 1

Answer:

Car B has the better fuel economy.

Step-by-step explanation:

Calculate the fuel consumption for the two cars:

Car A: (450 km) / (40.5 L) = 1.11 km per L

Car B: (220 km) / (18.7 L) = 1.18 km per L

Car B goes further on one L of gasoline than Car A.

If you bought 24 light bulbs, how much money would you save by buying the less expensive light bulbs?

Answers

with the more expensive light bulbs, the cost would be $155.52

with the less expensive light bulb, the cost would be $119.04

This means you would save $36.48

Answer:

$3.84 is the amount you save by purchasing the cheaper lightbulbs when buying 24.

Step-by-step explanation:

Alrighty, so!

With this one, I broke down the price per lightbulb (divided the money by the amount of bulbs in the package).

$4.96/4= $1.24/bulb

$6.48/6= $1.08/bulb

I then multiplied that amount per bulb by 24.....

$1.24 x 24 = $29.76

$1.08 x 24 = $25.92

.... And subtracted the lower number from the higher number to get the answer.

$29.76-$25.92= $3.84

Find the value of x and m∠HKL.

Answers

Answer:

x = 25 degrees ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25
