A car uses 20 gallons of fuel to travel 440 miles. How much fuel will the car use to travel 1054 miles?

Answers

Answer 1
Answer:

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If 20 gallons of fuel is used to travel 440 miles.

47.91 gallons of fuel is used to travel 1054 miles.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

A car uses 20 gallons of fuel to travel 440 miles.

This can be written as:

20 gallons = 440 miles

Divide both sides by 440.

20/4440 gallons = 1 miles

This means,

20/440 gallons is needed to travel for 1 mile.

Now,

20/440 gallons = 1 miles

Multiply both sides by 1054.

1054 x (20/440) gallons = 1054 miles

47.91 gallons = 1054 miles

This means,

47.91 gallons of fuel is used to travel 1054 miles.

Thus,

If 20 gallons of fuel is used to travel 440 miles.

47.91 gallons of fuel is used to travel 1054 miles.

Answer:

A

Step-by-step explanation:

- 1/5 of 5x is  -1 or just -x and -1/5 of 20 is -4. Then the other one is-1/4 of 4 is -x and -1/4 of -28 is 7. Now combine like terms so -x + -x is -2x and 7+ -4 or 7-4 is 3

There are two Right angled triangles in the given figure, with two missing sides, let's name the other missing side be "y "

According to Pythagoras theorem,

\boxed{ \large \boxed{h {}^(2) = {b}^(2) + p{}^(2) }}

note :

  • p = perpendicular / opposite side
  • b = base / adjacent side
  • h = hypotenuse

let's solve for " y² " first ( square of other missing side )

➢ \: \: {y}^(2) = {8}^(2) + 3 {}^(2)

➢ \: \: {y}^(2) = 64 + 9

➢ \: \: {y}^(2) = 73

now let's solve for "x " , by using pythagorous theorem

➢ \: \: {x}^(2) = {y}^(2) + {6}^(2)

➢ \: \: {x}^(2) = 73 + 36

➢ \: \:x {}^(2) = 109

➢ \: \: x = √(109)

Approximate :

➢ \: \: 10.44 \: \: units
