50 apples and 120 oranges were sold
Let the number of apples be represented by a
Let the number of oranges be represented by y
Based on the information given, the equation to solve the question will be:
a + y = 170 ....... i
a + 0.50y = 110 ....... ii
Subtract equation ii from i
0.50y = 60
Divide both side by 0.50
0.50y/0.50 = 60/0.50
y = 120
The number of oranges sold is 120
Apples sold will be:
a + y = 170
a = 170 - y
a = 170 - 120
a = 50
Therefore, 50 apples were sold.

Answer:
- r = √(3V/(πh))
- r ≈ 5.03 feet
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
This formula can be used to find the radius, or we can rearrange it to solve for the radius:
3V = πr²h . . . . multiply by 3
(3V)/(πh) = r . . divide by the coefficient of r²
r = √(3V/(πh)) . . . . take the square root
__
We can fill in the given values to find the radius.
r = √(3·225/(π·8.5)) = √(1350/(17π)) ≈ 5.03 . . . . feet
Answer:
B and E
Step-by-step explanation:
Fit's, they multiplied both sides by 4/3 instead of 3/4. Then they divided the answer by 3 instead of taking the cube root of both sides.
