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
Answer:
2400
2640
360
Step-by-step explanation:
the retailer has to sell it for the same price as the dealer.
so, both mark it for 2400 sale price.
if a customer buys it at the retailer, the retailer makes the 15% discount he got from the dealer as profit.
2400 = 100%
1% = 2400/100 = 24
15% = 24×15 = 360
the retailer makes this profit no matter what other fees or taxes are added.
the final price is then including 10% VAT
2400 = 100%
10% = 24×10 = 240
final price = SP + VAT = 2400 + 240 = 2640
y = 0.22(12) + .99 = 3.63
A 12 minute call will cost $3.63
Answer:55.56
Step-by-step explanation:
Answer:
The answer top your question is: 1/2, 3/2, 5/2 and 7/2
Step-by-step explanation:
Data
4 consecutive numbers that add up to 8
First number = n
2nd number = n + 1
3rd number = n + 2
4th number = n + 3
Now, add them up n + n + 1 + n + 2 + n + 3 = 8
Simplify like terms
4n + 6 = 8
4n = 8 - 6
4n = 2
n = 2/4 = 1/2
First number = n = 1/2
2nd number = n + 1 = 1/2 + 1 = 3/2
3rd number = n + 2 = 1/2 + 2 = 5/2
4th number = n + 3 = 1/2 + 3 = 7/2
