Answer:
x= 3
Step-by-step explanation:
6/4.5= 1.3
4/1.3=3
Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44
t= 86degree 86+86+30+Qdegre= 360 degree add Q×2 that's all
Answer:
3053.5517 cm^3 ; 1/8
Step-by-step explanation:
Given the following :
Volume (V) of sphere = (4/3)πr^3 where r = radius
Diameter of sphere = 18 ; radius(r) = diameter / 2 = 18/2 = 9cm
V = (4/3) × π × 9^3
V = 1.3333 × π × 729
V = 3053.5517 cm^3
When diameter(d) is reduced to half
d = d/2
Volume (V1) of sphere with diameter 'd' =
V1 = (4/3)π(d/2)^3
Volume (V2) of sphere with diameter 'd' reduced to half, d = d/2, d/2 * 1/2 = d/4
V2 = (4/3)π(d/4)^3
V1 / V2 = [(4/3)π(d/2)^3] / [(4/3)π(d/4)^3]
V1 / V2 = (d/2)^3 / (d/4)^3
V1 / V2 = [d^3 / 2^3] / [d^3 / 4^3]
V1 / V2 = 8 / 64
V1 / V2 = 1 / 8
