Answer:
17
Step-by-step explanation:
Zero dimensional doesn't exist. Define the structure of A or give a picture.
The third diagram is the correct answer.
You will have to write a system of equations.
Let x represent the number of child tickets.
Let y represent the number of adult tickets.
Your two equations will be:
5.60x + 9.10y = 1045.10
x + y = 136
This is going to be solved using the substitution method.
x + y = 136
x = 136 - y
Substitute x for 136 - y in the other equation.
5.60x + 9.10y = 1045.10
5.60(136 - y) + 9.10y = 1045.10
Distribute the outside terms through the terms inside the parenthesis.
761.60 - 5.60y + 9.10y = 1045.10
Combine like terms.
761.60 + 3.5y = 1045.10
Subtract 761.60 from both sides to get 3.5y by itself.
3.5y = 283.5
To get y by itself, divide both sides by 3.5.
y = 81
81 adult tickets were sold that day.
Answer:
D.
Step-by-step explanation:
We have been given the points A (-4, 52), B (3, 92), C (4, 1) and D (-3, -1).
Length of the diagonal AC can be calculated from the distance between two points formula or we can also use Pythagoras theorem to calculate the length of the diagonal. But to calculate the length of the diagonal from pythagoras theorem we need to calculate the length of the sides AB and BC, therefore, we will use distance formula to calculate the length of diagonal AC, directly.
Co-ordinates of point A is (-4, 52) and C is (4, 1), using the distance formula we get,
Therefore, the length of diagonal AC is , the closest option is option D.
