In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
(0,4)

Multiply the numerators together and the denominators:
2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21
The answer is 5/21
-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50
This can reduce to -14/25
Answer:
Step-by-step explanation:
Given:
A translation upward or downward affects the 
value of a coordinate while a translation left or right affects the 
value of a coordinate.
We are translating the whole triangle down three units, so we subtract all the values by 3.
We are also translating the whole triangle to left left five units, so we will subtract all the values by 5.
New Coordinates:
Answer:
Step-by-step explanation:
csc(Ф) is equivalent to the inverse of sin(Ф)
Since sin(Ф) = 3/7, the inverse of this would be 7/3
So,
