If a car weighs 1,750 kg, would you expect its fuel efficiency to be closer to 22 mpg or 28 mpg? Explain your reasoning
​

Answers

Answer 1

Answer:

closer to 22 mpg

Fuel-efficiency is the ability of a car to extract energy from fuel.The more the energy the car can extract from fuel, the greater fuel-efficiency the car has.Heavier vehicles require more energy to move because inertia and rolling resistance is high, leading to high fuel consumption.Reducing weight improves vehicle's efficiency.

Mary is 25 years old, and she owns her car, which she uses to drive to work.
Her collision deductible is $100, and she does not have comprehensive
coverage. If her car's safety rating is 20, what is her annual premium?

Answers

Answer:

2706$

Step-by-step explanation:

Assuming she does not have comprehensive coverage. If her car's safety rating is 12, her annual premium is $2,656.8.

What is annual premium?

The amount that a person pays an insurance company each year in exchange for insurance coverage is known as the annual premium.

Using this formula

Annual premium

=Deductible×2×Rating factor

For age 25 years the rating factor is 1.65.

So, Annual premium

= $820 × 2 ×1.65

= 820 x 3.24

= $2,656.8

Thus, her annual premium is $2,656.8

subtract 92 from both sides, then subtract 16 from both sides, and finally divide both sides by 2 to get 36

Answer:

3. Circumference= 50.27

4. Area= 201.06

*You must put the pi sign and not 3.14 to get you actual answer.

Step-by-step explanation:

3. The answer is 50.27 because the formula for circumference is 2 times pi times radius, so you do 2 x pi x 8 which equals 50.265 but after you round you get 50.27.

4. The answer is 201.06 because the formula for area with a radius is pi times radius squared, so you do pi x 8^2 which equals 201.061 but after you round you get 201.06.

2) 19+(-3)+6

Answer:

1: 1

2: 22

Step-by-step explanation:

1 ) -5 + (-1) is -6, because they both have the same sign.

-6+7} when there is a negative and a postive, put the postive in front

so it will look like this 7-6 which is 1

2) 19+(-3) is basically 19-3, which is 16, and 16+6=22

Extra note:

when you see n+(-n), always remove the + sign and subtract

when you see -n+n, always switch the roles of the two

when you see -n+-n, remove the - sign and add it back later

when you see -n-n, think of -n+n
