Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.

Since 30 times 5= 150, he worked 150 hours for the rest of the week.
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
-.425 divide the top number by the bottom number :)
Let AB be a chord of the given circle with centre and radius 13 cm.
Then, OA = 13 cm and ab = 10 cm
From O, draw OL⊥ AB
We know that the perpendicular from the centre of a circle to a chord bisects the chord.
∴ AL = ½AB = (½ × 10)cm = 5 cm
From the right △OLA, we have
OA² = OL² + AL²
==> OL² = OA² – AL²
==> [(13)² – (5)²] cm² = 144cm²
==> OL = √144cm = 12 cm
Hence, the distance of the chord from the centre is 12 cm.
