Answer:
6 hours.
Step-by-step explanation:
Let t represent time taken by plant 1 in hours to release the waste.
Part of waste released by plant 1 in one hour would be
.
We have been given that two chemical plant 1 releases waste twice as fast as plant 2, so time taken by plant 2 to release the waste would be
.
Part of waste released by plant 2 in one hour would be
.
We are also told that together they fill the tank in 4 hours. So part of tank filled by both plants working together in one hour would be
.




Therefore, it will take 6 hours for the faster plant to fill the tank working alone.
Answer:
A) AA postulate; 18
Step-by-step explanation:
Due to the similar triangles, we can set up the proportion and solve for x
8/(8+4) = 12/x
8/12 = 12/x
8*x = 12*12 ... cross multiply
8x = 144
x = 144/8
x = 18
Answer:
Mean = 10.181818181818181818181818
Median = 10
Mode = 8
Range = 13 - 8 = 5
Step-by-step explanation:
MEAN 8+8+8+9+9+10+10+12+12+13+13 = 112/11=10.1818 forever.
MEDIAN 8 8 8 9 9 10 10 12 12 13 13
count five in both directions
MODE most numbers in a number scheme
RANGE highest number minus lowest number.
