Supplementary angles equal 180 degrees combined. A right angle equals 90 degrees, so in order to equal 180 you need 90 more degrees. The answer is always ☺
Answer:
$475
Step-by-step explanation:
7+6+7+5 = 25
25*19 = 475
Don’t write out the word squared.
Answer:
y = -4/5x - 4
Step-by-step explanation:
y - y1 = m(x-x1)
4x + 5y = 20 ( subtract 4x on both sides)
5y = -4x + 20 (divide by 5 on each side)
y = -4/5x + 4
So we know one point is (0,4) y-intercept
now plug in (0,4)
y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)
y - 4 = -4/5x (now add 4 on each side)
y = -4/5x - 4
So if in 1/4 of an hour 75 gallons are pumped you would multiply 75 by four which will give you 300. This means 300 gallons are pumped in an hour
