13.
so out of the pool houses, how many have a hot tub
21/38=0.552=55% aprox
answer is 55%
12 is correct
14 technically, it 0 and -3, -3 could also be correct if you count the negativer root
1/5 x -3/1 is one i think
The order of magnitude is calculated by use of log function. log(240000) = 5.38 so the order is 5 (from what I've see we round down even if it was 5.999 but this may be wrong in some cases).
Answer: 14 cm
Step-by-step explanation:
First take out 1/4 of the pipe, the portion that is white. Then, half of three quarters of the pipe is blue. 1/2 of 3/4 is 3/8. 3/8(blue) + 2/8(white) = 5/8. Thus, 3/8 of the pipe is black. Thus, take 5.25(The length of the black portion) and multiply it by 8/3(reciprocal of 3/8) to get 14.
Hope it helps <3
