Alina spent no more than $45 on gas for a road trip. the first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon. which inequality relates the number of gallons of gas she bought at the first station, x, the number of gallons of gas she bought at the second station, y, and the total amount she paid? what are the possible values of y? 3.5x + 4y ≥ 45, y ≥ 11.25 3.5x + 4y ≥ 45, 0 ≤ y ≤ 10.375 3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25 3.5x + 4y ≤ 45, y ≥ 10.375

3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25  (c)

The correct option is 3.

Step-by-step explanation:

Let the number of gallons of gas she bought at the first station be x and the number of gallons of gas she bought at the second station be y.

It is given that the first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon.

Total cost is defied as

Alina spent no more than $45 on gas for a road trip.

                 .... (1)

If she bought all number of gallons from the second station, then

Divide both sides be 4.

Number of gallon can not negative.

                    .... (2)

Inequality (1) relates the number of gallons of gas and inequality (2) represent all the possible values of x.

Therefore, the correct option is 3.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
