The slope of the line represents that the a distance of 55 miles is covered each hour
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the distance in miles covered in x hours.
Using points (2, 110) and (7, 385) from the table:
Therefore the slope of the line represents that the a distance of 55 miles is covered each hour

Answer:
15. BE = 37.5
16. AD = 62.4.
17. ED = 37.5
18. Angle CDA=79 degrees
19. Angle BCD= 101.
20. Angle DAB=101.
Step-by-step explanation:
For problems 15-20, you'll use geometry theorem the definition of a parallelogram which says they have two pairs of equal parallel sides, equal opposite angles and that the diagonals in any parallelogram bisect each other into equal segments.
15. BE is half of 75. BE = 37.5
16. Since BC = 62.4 then AD = 62.4.
17. ED is half of 75. ED = 37.5
18. 79 degrees
19. Parallelograms add to 360 degrees so if two angles are 79 then 360-79-79 = 202 which is split equally in the other two angles. 202/2 =101. Angle BCD= 101.
20. Angle DAB is equal to Angle BCD so Angle DAB=101.
Answer:
1/4 × 16/3
Step-by-step explanation:
if 1 lap required 1/4 hour
the 16/3 require 1/4 × 16/3 hour ( cross multiplication)

Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
