15^ is equivalent to 0.15, or 15/100. If you divide both numerator (15) and denominator (100) by 5, you get 3/20.
28% corresponds to 0.28. What fraction would that be?

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.
AC = AB + BC
= (x + 2) + (7x - 3)
= (x + 7x) + (2 - 3)
= 8x - 1
AC = 8x - 1
QR = PR - PR
= (13y + 25) - (8y + 5)
= 13y + 25 - 8y - 5
= 13y - 8y + 25 - 5
= 5y + 20
QR = 5y + 20
Hence, simplified expression for AC = 8x - 1
Simplifie expression for QR = 5y + 20

Answer: 45 1/2
Step-by-step explanation:
Volume = 3 1/2 x 4 x 3 1/4
= 91/2
= 45 1/2 or 45.5
