Answer:
B)13 pints
Step-by-step explanation:
SO first we find the unit rate
We know that in 90 minutes (hour and a half), the water leaked 6 pints form 2;30 to 4
Now So we can divide to find unit rate
6/90=1/15
So 1 pint for every 15 minutes
And now we want to know the amount it takes from 2:30 to 6:30 which is 4 hours
40 hours is 240 minutes
SO we can divide now
240/15=16
SO 16 pints leaked but the question asked for remaining water in container
So 29-16 is 13
So B)13
12 gallons = 96 us liquid pints.
There are no numbers for this, thus you will have to use the quadratic formula.
5 hours hun just divide and times and maybe you will find it
1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x - 7y = -10</u>
<u>27y</u> = <u>65</u>
27 27
y = 2¹¹/₂₇
x + 4(2¹¹/₂₇) = 11
x + 8²²/₂₇ = 11
<u> - 8²²/₂₇ - 8²²/₂₇
</u> x = 2⁵/₂₇
(x, y) = (2⁵/₂₇, 2¹¹/₂₇)
