Answer:209ft
Step-by-step explanation:
We let y be the unknown value, which is length of conduit.
200^2 + 60^2=y^2
40000 + 3600=y^2
43600=y^2
Square both side
y= sqrt(43600)
y= 208.8061 ft
y=209 ft
You can guess and check, If you divide 48 by 60 it gives you 4/5. The answer is A
-1/2 / 3/4 =
The first step is to flip the second fraction and change division to multiplication. Then multiply straight across.
-1/2 x 4/3 = -4/6
In simplified form:
-4/6 = -2/3
Answer: 9 houses
Step-by-step explanation:
Step 1:
Since 2/3 of the houses were sold last month, 1/3 of them were left.

Step 2:
Since 2/5 of the remaining houses were sold this month, 3/5 of them were left
15 * 3/5 = 9 houses left to be sold
there's your answer hope this helps :)
