An auditorium has rows of seats with a seats in each row Kayla

Mathematics
1 answer:
Lelu [443]2 years ago
3 0

Step-by-step explanation:

  • <em>Note: there is a typo, 'a' should be '8'</em>

The number of seats in each row is 8 and the total number of seats is between 70 and 150.

<u>Let </u><u>x</u><u> be the number of rows, then we have the inequality:</u>

  • 70 ≤ 8x < 156

<u>Divide all sides by 8 to get:</u>

  • 70/8 ≤ x < 156/8
  • 9 ≤ x ≤ 19 (taking closest integers)

So the number of rows is between 9 and 19 both inclusive.

All possible number of rows

  • 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19

Since the graph of the given functions is a straight line, the graph belongs to a linear function, as all linear functions have their graphs as a straight line. For a non-linear function the graph is not a straight line. 

For a relation (non-function), the line passes through same value of x for more than one points. 

Hence the correct answer is "Linear Function"

BaLLatris [955]

Answer:

1. 56.52 inches

2. 141,300 inches

Step-by-step explanation:

One turn of the tire is the circumference. Therefore, we have to find the circumference first. C = πd = 18π = 18 × 3.14 = 56.52 in

2500 rotations would be 2500 ⋅ 56.52 in = 141,300 in

I hope this helps and please mark me as brainliest!
