Answer:
Step-by-step explanation:
7y⁴ = 7y²(z - 3ax)
Divide both sides by 7y².
y² = z - 3ax
Add 3ax to both sides. Subtract y² from both sides.
3ax = z - y²
Divide both sides by 3a.
Answer: 45 cats
Step-by-step explanation: since you got 30 dogs. 2x15= 30 so to get the number of cats do 3x 15= 45cats
The equation for volume of a sphere is:
Volume = 4/3 * PI * r^3
r is the radius = 1 inch
Volume is given as 4 cubic inches per second increase.
Given: dv/dt = 4 cubic inches per second.
Need to find dr/dt
Formula for volume of a sphere is: V = 4/3 * π * r^3
so now we have:
4 in^3 = 4 * π *1^2
Divide both sides by 4 * π *1^2
4 in^3 / 4π = 1/π inch per second.
The answer is 1/π inch per second ( exact answer)
or as a decimal: 0.3183 ( round as needed).
The area is 12.57
Formula: PieR^2
Answer:
10
Step-by-step explanation:
Because if the number of girls is the same as the boys you just devide 20 by 2 and get 10
