Answer:
-7b+3
Step-by-step explanation:
first step you will find numbers if you take -2.2 to get those numbers
8 + 4 = 12
1/3 + 2/3 = 1
12 + 1 = 13 cups of nuts.
For each bus there will be 9 students
Answer:
1/2
Step-by-step explanation:
Since it is given that the cone and the hemisphere have the same height, and since the height of a hemisphere would be equal to its radius, the cones height must also be equal to its base radius.
With this information we can use the respective volume formulas.
Hemisphere:
πr^3
Cone:
πhr^2
Since h (height) = r we can say the cone volume equals:
πr^3
Now to find the ratio we divide the cone volume equation by the hemisphere volume equation
pi and r^3 cancels out from the division and we are left with
ratio = (1/3)/(2/3)
ratio = 1/2
