Answer

a car gets 28 miles per gallon of gasoline. the number of gallons used, x, and the number of miles driven, y, are graphed. which of the following is an ordered pair on that graph?

(1.75, 42)

(3.5, 96)

(2.25, 63)

(4.25, 126)

worth 97 points for you !

2.25, 63

Step-by-step explanation:

plus the values into equation y=28x

(2.25,63)

Step-by-step explanation:

Since the car gets 28 miles per gallon, the ratio of x:y is 1:28 because x is the gallons and y is the number of miles driven. Since 63/2.25 is 28, it’s an ordered pair on the graph.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

the least common denominator is 40
