Answer:
<u><em>60 cm³</em></u>
Step-by-step explanation:
<em>Volume (cube) = l x b x h</em>
<em>= 5 x 4 x 3</em>
<em>= 20 x 3</em>
<u><em>= 60 cm³</em></u>
A-b=8
2a+3b=51
2a-2b=16
2a+3b=51
Subtract both
-5b=-35
b is 7 and a is 15
Answer:
13 1/8
Step-by-step explanation:
3/8-(-51/4)
Subtracting a negative is like adding
3/8 + 51/4
get a common denominator
3/8+ 51/4 *2/2
3/8 + 102/8
105/8
8 goes into 105 13 times with 1 left over
13 1/8
Answer:
Auxiliary pump should be started at 6:36 PM
Step-by-step explanation:
Let the volume of oil tanker be V.
An oil tanker can be emptied by the main pump in 5 hours,
An auxiliary pump can empty the tanker in 12 hours,
We need to find when should the auxiliary pump be started so that the tanker is emptied by 9 PM if the main pump is started at 5 PM.
Difference in times = 4 hours
That is main pump works for 4 hours and let auxiliary pump works for t hours.
We have
So auxiliary pump works for 2.4 hours,
It should be started at 9 - 2.4 = 6.6 PM = 6:36 PM
Auxiliary pump should be started at 6:36 PM
