Mathematics Middle School

Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?

Answers

Answer 1

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

Answer 2

57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .

Point C is the image of C (-4, -2) under a reflection across the y-axis.

What are the coordinates of C?

Answers

Answer: (4,-2)

Step-by-step explanation:

if you reflect a point across the y-axis, that point must be on the same horizontal line then to the pre-mage meaning the y coordinates must remain the same. From their we want the points on both sides of the t-axis to have the same distance. x and -x have the same distance from 0. Therefore this means you will need to take the opposite of X.

So point (x,y) being reflecting over the y-axis will give us (-x,y).

(x , y)--->(-x,y) mean you have (-4,-2)---->(4,-2)

Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45

Answer:

y= -2x + 7

Step-by-step explanation:

first, we know the slope will be negative because the like is going down

lets look at the point that is on the y-axis, this will be our y-intercept

7 is the point hitting the y axis, plug this into the equation

so far we have y=7

There are 5 candy canes for every 9 presents. How many candy canes are there if there are 108 presents? (PLEASE SHOW YOUR WORK TOO! its for a grade:( )

Answers

Answer:

60 candy canes

Step-by-step explanation:

To find how many candy canes we have to remember that there are 5 candy canes for every 9 presents.

108 is divisible by 9 so we do the equation:

108 ÷ 9 = 12

Now we multiply 12 by 5 since theres 5 candy canes per 9 presents

12 × 5 = 60

To check our work we can divide-

9 ÷ 5 = 1.8

108 ÷ 60 = 1.8
