We use the law of Cosines to find b=AC opposite B
We know all the sides of triangle ABM so we can use the law of Cosines, this time to solve for
Substituting,
Answer: AC=√39
we know that
area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)
solve for scale factor
scale factor=√[area larger triangle/area smaller triangle]
scale factor=√[144/100]------> scale factor=1.2
therefore
measure EF=scale factor *measure BC
solve for measure BC
measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm
the answer is
measure BC is 12.5 cm
We know that there are 3,000 gallons in the swimming pool and that one hose filled it in x minutes (or hours, doesn't matter), while the second hose filled it 4x minutes. Together we have 5x (five parts that hoses have filled), so all we need to do is to divide 3,000 by 5:
3,000 ÷ 5 = 600
Now we can see that one hose filled <u>600 gallons</u>, while the other one filled 4 * 600 = 2,400 gallons.
