Answer:
It will take 4 hours and 48 minutes with both pipes.
Step-by-step explanation:
Add their rates of filling
1st pipe's rate = ( 1 tank ) / ( 12 hrs )
2nd pipe's rate = ( 1 tank ) / ( 8 hrs )
Let, t = hrs to fill tank using both pipes
(1 / 12) + (1 / 8) = (1 / t)
Multiply both sides by 24t
2t + 3t = 24
5t = 24
t = 4.8
0.8 x 60 = 48
It will take 4 hours and 48 minutes with both pipes
Answer:
about 16 times bigger
Step-by-step explanation:
' 40% ' means 0.4 .
You said that 60 = 0.4 x Full
Divide each side by 0.4 : 60 / 0.4 = 1 x Full
Full = 150 .
Answer:
The correct option is C
Step-by-step explanation:
A: We know that the lower quartile is 144, and the upper quartile is 129.5 is you add them all up it is going to equal 273.3. So we know that A can now be crossed out.
B: We know that the lower quartile is 146, and that means the upper quartile is 136.5. So adding all of these numbers up we ill get 282.5 So now <u>B can be crossed out</u>
C: The lower quartile is 114 and the upper quartile is 129.5 and when we add those two numbers up we are going to get 243.5. So we are going to keep this number
D: For the last one we know the lower quartile is 214 and upper is 129.5, and when we add this we get 343.5. So we can cross this out and<u> the only one we have left is going to be C</u>
<u>Hope this help's</u>
