the number of students attending college in 2015 was 20.2million. this number expected to increase to 23.1 million by the year 2
1 answer:
Answer:
The expected percent increase is <u>14.4%</u>.
Step-by-step explanation:
Given:
The number of students attending college in 2015 was 20.2million.
This number expected to increase to 23.1 million by the year 2024.
Now, to find the expected percent increase.
The number of students was = 20.2 million.
The number of students expected to increase = 23.1 million.
The number of students increased = 23.1 - 20.2 = 2.9 million.
Now, to get the expected percent increase:
<em>Thus, the expected percent increase nearest to tenth = 14.4%.</em>
Therefore, the expected percent increase is 14.4%.

Answer:
1250
Step-by-step explanation:
We are given that the playground is fenced on three sides of the playground and the four side has an existing wall.
Let the length of the rectangle be 'X' feet and width be 'Y' feet.
As the fencing is done using 100 feet of fence. We get the relation between the sides and the fence as, X + 2Y = 100.
As, X + 2Y = 100 → X = 100 - 2Y
Now, the area of the rectangle = XY = X × ( 100 - 2Y ).
i.e Area of the rectangle = .
The general form of a quadratic equation is .
The maximum value of a quadratic equation is given by .
Therefore, the greatest value of is at Y =
=
= 25.
Thus, Y = 25 and X = 100 - 2Y → X = 100 - 2 × 25 → X = 50.
Hence, the area of the rectangle is XY = 50 × 25 = 1250 .
