Answer:
Joy is correct
Step-by-step explanation:
we know that
1 cup=1/2 pint
step 1
Convert pint to cups
Divide 4/5 pint by 1/2 to convert to cups
so
step 2
Convert to mixed number
therefore
126 gallons per minute
<u>-5 ± √5² - 4 · 1 · 4</u>
2 · 1
ax²+bx+c=0 (quadratic equation)
x=<u> -b ± √b² - 4ac</u>
2a
a= 1
b= 5
c= 4
-<u>5 ± √5² - 4 · 1 · 4</u>
this is your answer
