a=1
b=3
a^3*b^2-2a=1^3 * 3^2 -2*1 = 1*9 -2 = 9-2= 7
8/9 = 12/p multiply by p on both sides
(8/9)p = 12 distribute p
8p/9 = 12 multiply by 9 on both sides
8p = 108 divide by 8
p = 108/8 simplify
p = 27/2
Answer:
128
Step-by-step explanation:
Billy has 55 stamps and his brother Tommy has 73. Add 73 and 55 together. 55+73=128
Answer:
h = 54 feet
Step-by-step explanation:
The equation for the volume of a cone is V = × π × r² × h.
You have the volume, which is 8,138.88, and the radius of the base, which is 12.
V = 8,138.88
h = 12
π = 3.14
When you plug everything you know into the equation, you get:
V = × 3.14 × r² × h.
8,138.88 = × 3.14 × (12)² × h
After you multiply everything on the right side, you come out with:
8,138.88 = 150.72 × h
To find h, you can divide each side by 150.72.
8,138.88 ÷ 150.72 = 54 feet!
