A watering can dispenses water at the rate of 0.25 gallon per minute. The original volume of the water in the can was 6 gallons. Which set of ordered pairs shows the volume of water in the can in gallons, (y) as a function of time in minutes, (x) from the first minute after the can starts dispensing water? A. {{1, 6.0), (2, 5.75), (3, 5.50}}
B. {{6.0, 1), (5.75,2), (5.50, 3}}
C.{{1, 5.72), (2, 5.50), (3,5.25}}
D{{5.75,1), (5.50,2), (5.25, 3}}

step-by-step explanation:

a

1696 hundred thousand

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
