In the last race , the first car in the pit used 1 3/4 tanks of gas, the second car used 2 1/8 and the third car used 1 1/2 tanks of gas. what was the total positive or negitive change in the amount of gas for all three cars

tanks of gas

Step-by-step explanation:

Let the x be the number of tanks of gas, then

The amount of gas used by first car=

The amount of gas used by second car=

The amount of gas used by third car=

Thus, the total change in the amount of gas for all three cars=

Since, the amount of gas tanks of gas is used for all three cars.

Therefore, the total amount would be negative .

hence, the answer is   tanks of gas.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer is b
