Answer:
80, every 5 percent is 4 people. So every 25% is 20. 20 x 4 is 80.
Step-by-step explanation:
The circumference of the circle
is given by the equation C = pi * D. Incorporating the length of the diameter
into the equation, we have,
C = pi * D
C =
pi * 7cm
C =
21.99 cm
Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
Answer:
x = 44
Step-by-step explanation:
log4(x + 20) = 3
Raise each side to the power of 4
4^ log4(x + 20) = 4^3
x+20 = 4^3
x+20 = 64
Subtract 20 from each side
x+20-20 = 64-20
x = 44
