Answer:
2
Step-by-step explanation:
Take any 2 points on the graph,
(50, 10) & (90, 90)
Use the slope formula:
= (90-10)/(90-50)
= (80)/(40)
= 2
Hence, the slope is 2.

Answer:
Her second lap was 8% better when compared to her first lap.
Step-by-step explanation:
Given:
Emily ran her first lap in 75 seconds she ran her second lap in 69 seconds.
Now, to find how much better was her second lap when compared to her first lap.
Emily ran her first lap in 75 seconds.
Emily ran her second lap in 69 seconds.
So, we get the difference in seconds:
Thus, in her second lap she was 6 seconds better than first.
Now, to get the percentage of her first lap better than second:
Therefore, her second lap was 8% better when compared to her first lap.
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3
= (3/3) / (9/3)
= 1 / 3
(9+5+6)(5-6)
(20)(-1)
= -20
