Option A) 14/250 = N/350 is correct.
Kevin wants to change the engine in her car. The current engine is 250 cubic centimeters and has a 14 inch fan belt. The new engine is 350 cubic centimeters and has proportionally larger fan belt.
<h3>What is proportionality?</h3>
proportionality can be defined as, how much the number is relatable to other number i.e. x =2y x is two times proportion to y.
Hence, in the question
for 250 cc engine it has 14 inch belt
for 350 cc engine it has N inch belt(let)
proportionality can be given as
14 ∝ 250
N ∝ 350
dividing both equation
N/14=350/250
or 14/250=N/350
Thus, the required proportion is given as 14/250=N/350.

:)
F(x) = -1.50x + 40.....basically, this is saying that Gloria has 40 bucks in her lunch account and each meal costs her 1.50.
By changing the -1.50 to -2.75 means she is paying more for her meals...the cost of a meal went up from 1.50 to 2.75.

Answer:
4.7 miles
Step-by-step explanation:
10, 000 steps (stride) * 30 inches per stride = 300,000 inches per day.
To know miles, we need the miles-to-inches conversion, which is:
1 miles = 63,360 inches
To find number of miles walked in a day, we would need to divide total (300,000) by 63,360 :

So, that 4.73 miles a day
Rounded to nearest tenth, 4.7 miles per day
