5 years from now, Johnathan will be (5 + 4) = 9 years
Step-by-step explanation:
Let Belinda's age = x
Jonathan's age =1/3 x
In 12 years, Belinda will be m years old :
Belinda's age now = x
Jonathan's age 5 years from now, if m = 36
Belinda's age in 12 years, Belinda's age = m
x + 12 = 36
x = 36 - 12
x = 24 years
Hence Belinda's age now is 24
Jonathan's age now is (1/3) * 12 = 4 years
Hence, 5 years from now, Johnathan will be (5 + 4) = 9 years
The total area would be 9 1/4 multiplied by 8 4/5 which would equal 81.4 inches
volume of a cone = (1/3)*pi*r^2*h
180 = pi(r^2)h
180/pi(r*2) = h
Answer:
20 Bicycles
Step-by-step explanation:
The function for the average cost,C(x) [in hundred of dollars] per bicycle whenever x hundred bicycles are built is given as:

The minimum value of C occurs at the axis of symmetry.
Axis of Symmetry, 
Comparing with the standard form of a quadratic equation 
a=0.5, b=-0.2

x=0.2 Hundreds =0.2 X 100 =20
When Aki's Bicycle Designs produces 20 Bicycles, the cost is minimized.
