Number of females = f
Total number of people in audience = n
0.4n = f
f + (f+ 100) = n
2f + 100 = n
Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n
2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500
There were 500 people in the audience.
Answer:
18
Step-by-step explanation:
A' = (- 3, 0 )
(x, y ) → (x - 5, y + 2 ) means subtract 5 from the original x-coordinate and add 2 to the original y- coordinate
A(2, - 2 ) → A'(2 - 5, - 2 + 2 ) → A'(- 3, 0 )
Answer: are diagrams that depict the direction and relative magnitude of a vector quantity by a vector arrow. Vector diagrams can be used to describe the velocity of a moving object during its motion. For example, a vector diagram could be used to represent the motion of a car moving down the road.
