number of boys:number of girls= 11:9
There are 124 more boys than girls.
Work out the total number of students at the school
Answers
Answer:
Total students = 1240
Step-by-step explanation:
Boys : girls = 11 : 9
Number of boys = 11x
Number of girls = 9x
11x - 9x = 124
2x = 124
x = 124/2
x = 62
Number of boys = 11x = 11 *62 = 682
Number of girls = 9x = 9*62 = 558
Total students = 682 + 558 = 1240

((Honestly I don't understand anything, I was busy throwing up while my teacher was showing us how to do it))
Answers
Answer:
$ 118.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 660 × 0.09 × 2 = 118.8
I = $ 118.80
The simple interest accumulated
on a principal of $ 660.00
at a rate of 9% per year
for 2 years is $ 118.80.

List the angles of triangle WXY in order from smallest to largest.
Answers
Answer: W, Y, X (choice D)
=======================================================
Explanation:
The square angle marker means angle X is 90 degrees.
For any triangle, the three angles always add to 180
X+Y+W = 180
90+(2x+9)+(2x+1) = 180
4x+100 = 180
4x = 180-100
4x = 80
x = 80/4
x = 20
Use this x value to find the other angles
angle Y = 2x+9 = 2*20+9 = 49
angle W = 2x+1 = 2*20+1 = 41
As a check,
X+Y+W = 90+49+41 = 180
which confirms we have the right angles.
The last step is to sort the angles from smallest to largest
That would lead to W, Y, X which is choice D

the lenght of the floor is 32 m longer than its width and there is greater than 200 square meters. you will cover the floor completely with tiles. what will be the possible dimension of the floor?
Answers
To figure out the dimensions we need to figure out the value of the variable (x)
This means that the length is xm+32m (the m is for metres) and that the area is a>200m2
Because it says what is the possible dimensions let make the area 201m2
The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x
201=x+x+32
So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x
Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m
Therefore the dimensions of the floor is 116.5m by 84.5m

What is the slope of a line that passes through the points (2,0) and (6,−12)
Answers
Answer:
slope = -3
Step-by-step explanation:
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (2, 0), (6, -12)
(2, 0) = (x1, y1)
(6, -12) = (x2, y2)
To find the slope, input the two given points into the formula used to find slope:
[tex]\frac{-12-0}{6-2}[/tex]
Simplify:
-12 - 0 = -12
6 - 2 = 4
[tex]\frac{-12}{4} = -\frac{3}{1}=-3[/tex]
The slope of the line is -3.
Hope this helps :)

4) 26.6m
Answers
Answer:
7.3m
Step-by-step explanation:
Area is l * w
The length and width of a square are the same, so that means we can use square root for this problem.
The square root of 53.29 is 7.3
7.3*7.3 = 53.29 (<- to double check)
