Answer:

10%

Step-by-step explanation:

To understand the concept around percentage increase or decrease, we always state clearly the conditions.

Please always remember:

(Increase / Original number) * 100

Number of LAST YEAR enrolled students at Olsen Middle School:

= 520 Students

Number of THIS YEAR enrolled students at Olsen Middle School:

= 572

Difference in the number of students in both years:

= This year's students number - Last year's students number

= 572 - 520

= 52 students (Increase)

To solve for the percentage increase:

= (Increase / Last years Total) * 100

= (52 / 520) * 100

= 0.01 * 100

= 10 %

Percentage increase = 10%

Answer:

The percent of increase in the number of students is 10%.

Step-by-step explanation:

The percent increase in the number of students is the absolute increase divided by the number of students last year.

Last year: 520 students

This year: 572 students

Absolute Increase: 572 - 520 = 52 students

Percent increase:

p = \frac{52}{520} = 0.1

The percent of increase in the number of students is 10%.

How can you identify the opposite and the absolute value of a rational number???
Brut [27]
The absolute value is its distance on a number line from 0. The absolute value of 5 is five. The absolute value of -2.75 is 2.75. The opposite is basically the number multiplied by negative one(change the symbol). The opposite of a negative number is positive and the opposite of a positive number is negative.

Starting from 300 feet away, a car drives toward you. It then passes by you at a speed of 48 feet per second. The distance dd (i
Effectus [21]

There are actually two times that the car is 60 feet from you. The 1st time (t1) is when it is 60 feet in front of you and the 2nd time (t2) is when it is 60 feet past of you.

Therefore:

60 = 300 – 48 t1

48 t1 = 300 – 60

t1 = 5 seconds

 

-60 = 300 – 48 t2

48 t2 = 360

t2 = 7.5 seconds

 

So at 5 seconds and 7.5 seconds

When the expression 3(x²+6-3x) - (2x²-8) + 3(x² + 4x) is simplified, the coefficient
DochEvi [55]

The correct answer is option C which is 3.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression will be solved as follows:-

E = 3( x² +6 -3x)- ( 2x² - 8 ) +3(x² + 4x )

E = 3x²+18-9x-2x²+8+3x²+12x

E= 4x² +3x+8

We can see the coefficient of x is 3.

Therefore the correct answer is option C which is 3.
