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.

5 - 6 - 9 - 8 - 5 - 4 + 5 - 5 -5 -5 - 32 = ?
musickatia [10]

5 - 6 = -1

-1 - 9  = -10

-10 - 8 = -18

-18 - 5 = -23

-23 - 4  = -27

-27 + 5  = -22

-22 - 5 = -27

-27 -5 = -32

-32 -5  = -37

-37 - 32 = -69

Answer = -69

Andrea is buying some new shirts and sweaters. she is able to buy 3 shirts and 7 sweaters for $137 or she is able to buy 8 shirt
Vikki [24]

Answer:

$33

Step-by-step explanation: ( pls brainiest)

Let the cost of each shirt is $ x, and the cost of each sweater is $ y.

Since, cost of each shirt is $ x, the cost of 3 shirts will be $ 3x and cost of 2 shorts will be $ 2x.

Likewise, cost of each sweater is $ y, so the cost of 2 sweaters will be $ 2y and cost of 4 sweaters will be $ 4y.

Andrea was able to buy 3 shirts and 2 sweaters for $114. This means:

Cost of 3 shirts + Cost of 2 sweaters  = 114

3x + 2y = 114                                            Equation 1

She was able to buy 2 shirts and 4 sweaters for $164. This means

2x + 4y = 164

Dividing both sides by 2, we get:

x + 2y = 82                                              Equation 2

Subtracting Equation 2 from Equation 1, we get:

3x + 2y - (x + 2y) = 114 - 82

3x + 2y - x - 2y = 32

2x = 32

x = 16

Using the value of x, in Equation 2, we get:

16 + 2y = 82

2y = 66

y = 33

Since, x represents the cost of shirt, the cost of each shirt is $ 16.

y represents the cost of sweater, so the cost of each sweater is $ 33.

Evaluate and show work 1/2 divided by 36 + 16 times 1/72
Gwar [14]

Answer:

17/72

Step-by-step explanation:

Let's make this equation easier to read.

.5/36 + 16(1/72)

Start by remembering PEMDAS

Parentheses

Exponents

Multiply

Divide

Add

Subtract

This is the order in which you will solve the problem. So multiplication first, then division, and finally addition.

Multiply 16 and 1/72

16/1 x 1/72  multiply across to get 16/72 which can be reduced to 2/9.

Divide .5 (or 1/2) by 36. To do this, multiply by the reciprocal of 36

1/2 x 1/36 = 1/72

Your equation is now

2/9 + 1/72

Your common denominator is 72, so multiply top and bottom of 2/9 by 8.

16/72 + 1/72 = 17/72
