Answer:
243 students' favorite color is red
Step-by-step explanation:
if 55% of the students said their favorite color was blue, then 45% chose that red was their favorite color
we can get 45% of 540 using a cross-multiplication equation
45% is 45/100
45/100 is to ?/540
the (?) represents the value of students who chose red as their favorite color (we do not know this but we can figure it out using cross-multiplication)
45 times 540 is 24300
24300/100 = 243.

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.

Answer:
We conclude that the line joining the mid-point of two sides of a triangle is equal to half the length of the third side. The converse of this theorem states: If a line is drawn through the mid-point of a side of a triangle parallel to the second side, it will bisect the third side.
