Step-by-step explanation:
calculate the total
42+ 14 = 56
42/56 = x/100
4200 / 56x = 75
the answer is 75%
Answer: If 1 pair of socks = 4 and 1 shirt = 10 then your answer will be C, 14.
Explanation: in the beginning it says ONE PAIR OF SOCK AND 2 SAME SHIRT =24. One sock=4 and 2 shirts=20 , 20 + 4 = 24. Solved.
Then 3 pairs of socks (4 x 3 = 12) and 2 of the same shirts (10 + 10 = 20) then 20 + 12 = 32!!
Answer:
Rate of change in height of the water level is 2.91 cm per second.
Step-by-step explanation:
Height of the inverted pyramid = 10 cm
Length of the square base = 7 cm
If water is filled up to the level of h cm then the volume of water up to height h will be
V =
V =
It is given that rate of water is filling with 70 cubic centimeters per second.
From two similar triangles in the figure attached,
By replacing the value of h,
V =
V =
V =
Now we integrate the equation with respect to time 't'
70 =
For h = 7 cm
Therefore, rate of change in height of the water level is 2.91 cm per second.
Hence the number of cups of water he will use is: 16/3 cups of water
