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:
Step-by-step explanation:
Given
Reflected and translated to B'
Required
Find the measure of B'
When an angle is reflected and/or translated (irrespective of the number of units of reflection and translation), the resulting angle always equal the initial angle.
This is so because, reflection and translation are rigid transformations and as such, they do not alter the length of measurements.
Hence:
Answer:
V = 115.5 cubic yards
Step-by-step explanation:
V (cone) = 1/3πr²h
just substitute given values to get:
r = 7/2 or 3.5
h = 9
V = π(3.5²)(9)/3
V = 115.5 cubic yards
Answer:
18x² - 24x + 9
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x) , that is
f3x - 2)
= 2(3x - 2)²+ 1 ← expand factor using FOIL
= 2(9x² - 12x + 4) + 1 ← distribute parenthesis by 2
= 18x² - 24x + 8 + 1
= 18x² - 24x + 9
I think its 6 but im not sure to be exactly right
