We know that
[volume of the cone]=(1/3)*pi*r²*h
for r=2 in
h=4 in
[volume of the cone]=(1/3)*pi*2²*4-----> 16.747 in³
volume of the hemisphere=(4/6)*pi*r³
for r=2 in
volume of the hemisphere=(4/6)*pi*2³----> 16.747 in³
[<span>the density of the ice cream]=mass ice cream/volume ice cream
</span>
mass ice cream=35 oz-3 oz-----> 32 oz
volume ice cream=volume of a cone +volume of hemisphere
volume ice cream=16.747+16.747----> 33.494 in³
density ice cream=32/33.494-----> 0.955 ounces/in³
the answer is
0.955 ounces/in³
Answer:60 mph
Step-by-step explanation:
F(x) = 8x-x^2 only if x is equal to 8 or less than 8
OR
f(x) = x^2+3 only if x > 8
We can only pick one of the two paths. The function f(x) can't be both at the same time. In the case of computing f(8) we have the input x = 8. It won't fit the bottom piece as x > 8 is false when x = 8. The inequality 8 > 8 is false
So instead we pick the top piece
x = 8 ----> so "x is less than or equal to 8" is true
f(x) = 8x - x^2
f(8) = 8*8 - 8^2
f(8) = 64 - 64
f(8) = 0
The final answer is 0
Answer: she should get 30.45 miles per gallon with her new tyres.
Step-by-step explanation:
After buying the Dunlop tires at a local Goodyear store, the salesperson told her that her mileage would increase by 5%.
If before this purchase, Maria was getting 29 mpg, it means that the amount by which her mileage will increase is
5/100 × 29 = 0.05 × 29 = 1.45 miles per gallon.
Therefore, the number of mileage that she should be getting with the new tires would be
29 + 1.45 = 30.45 miles per gallon.
