if a car travels 370.3 miles on 52 liters of gas, how many liters of.gas.will take to go 722 miles.if the car travels at the sam

blsea [12.9K]

Answer:

101.4 liters.

Step-by-step explanation:

First of all we will find mileage of car.

$\text{Mileage of car}=\frac{\text{Total distance traveled}}{\text{Total amount of fuel}}$

$\text{Mileage of car}=\frac{370.3\text{ miles}}{52\text{ liters gas}}$

$\text{Mileage of car}=7.12115\frac{\text{ miles}}{\text{ liters gas}}$

We can see that car travels at the rate of 7.12 miles per liter gas. Now let us find amount of gas needed to travel 722 miles at the same rate.

$\text{Amount of gas needed}=\frac{722}{7.12}$

$\text{Amount of gas needed}=101.388$

Therefore, it will take 101.4 liters of gas to travel 722 miles.

What is the distance between the points (21,-30) and (3,8)

Scilla [17]

Answer:

approximately 42.05

Step-by-step explanation:

We know that the distance formula is $\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }$ , so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that

x₂=3

y₂=8

x₁=21

y₁=-30

Then, we can plug it into the formula to get $\sqrt{(3-21)^{2} +(8-(-30))^{2 }} = \sqrt{18^{2}+38^{2}}=sqrt{1769}= 42.05 (approximately)$

Need help 25 points

Zina [86]

Answer:

The answer is 50.27 yards.

Step-by-step explanation:

You divide the diameter in 2, which gives you the radius of 4. Then you must square the radius, or multiply it twice, 4 times 4, to get 16. Then multiply that by pi or 3.14, which is 50.27. Hope this helped and please give brainliest if possible! :)

katrin2010 [14]

Answer is 7.25

Today's price was: 7.375

The question is saying that it went up .125 from yesterday's total, which means you have to take away .125 to get back to yesterday's total closing price

7.375 - .125 = 7.25
