Answer: Each donor donated $70.5 per lap.
Step-by-step explanation:
1. If she got 8 donors and each one of them sponsored 5 laps, then the total number of laps was:
laps
2. Hailey raised a total of $2,820, therefore, you can calculate the amount of money donated by each donor (which you can call ) by dividing $2,820 by 40 laps, as you can see below:
Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (3, 6)
m = =
Since division by zero is undefined then the slope of the vertical line is undefined.
Answer:
the largest angle of the field is 149⁰
Step-by-step explanation:
Given;
perimeter of the triangular filed, P = 120 m
length of two known sides, a and b = 21 m and 40 m respectively
The length of the third side is calculated as follows;
a + b + c = P
21 m + 40 m + c = 120 m
61 m + c = 120 m
c = 120 m - 61 m
c = 59 m

Consider ABC as the triangular field;
Angle A is calculated by applying cosine rule;
Angle B is calculated as follows;
Angle C is calculated as follows;
Therefore, the largest angle of the field is 149⁰.
