Let's call
the number of hours it takes for A to fill the pool and
the number of hours it takes for B to fill the pool.
We have
and
hence
hence
and thus
.
Divide each term by −5 and simplify. t ≤ −14. So A. should be the correct answer.
Answer:
13) a and b, b and c
14) a = 59°, b = 121°, c = 59°
15) a = 45°, b = 135°, c = 135°
16) a = 72°, b = 108°, c = 108°
In order to estimate this problem we must first estimate the two numbers involved.
137,638 rounds up to 138,000.
Since the 6 is bigger than 5 it makes the number 7 round up to 8
Now..
52,091 rounds out to 52,000
Since the number to the left of the 2 is not bigger than 5 then it stays the same at 52,000
Now we have to add our estimated numbers.
138,000 + 52,000 = 190,000
Your answer is 190,000
Good Luck! :)
