Answer:
2, 10%, 15, 42
Step-by-step explanation:
18 / 9 = 2
Total number of students = 60
6 / 60 = 1/10 or 10%
1/3 ride the bus, so a sample of 45 would give 15
7/60 ride a bike so multiply by 360 = 42

5y-14=2y-2 solve for y and show work plz
Answer:
y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
5y−14=2y−2
Step 1: Subtract 2y from both sides.
5y−14−2y=2y−2−2y
3y−14=−2
Step 2: Add 14 to both sides.
3y−14+14=−2+14
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
5y + -14 = 2y + -2
-14 + 5y = 2y + -2
-14 + 5y = -2 + 2y
-14 + 5y = -2 + 2y
-14 + 5y + -2y = -2 + 2y + -2y
5y + -2y = 3y
-14 + 3y = -2 + 2y + -2y
2y + -2y = 0
-14 + 3y = -2 + 0
-14 + 3y = -2
-14 + 14 + 3y = -2 + 14
-14 + 14 = 0
0 + 3y = -2 + 14
3y = -2 + 14
-2 + 14 = 12
3y = 12
y = 4

Find the total area for the following composite shape.
A.48 sq m
B.36 sq m
C.84 sq m
D.64 sq m
Answer:
C. 84
Step-by-step explanation:
To make it easier to find the total area, you should break the shape into two parts, a triangle and a rectangle.
Step 1:
To find the rectangle area we now we have to multiply l * w
In this case, the length is 12 and the width is 4 so 12*4 = 48
Step 2:
To find the area of the triangle you have to do the formula A = 1/2bh where b is the base 12, and h is the height (10-4) 6. So 6*12 = 72 and 72/2 is 36
Step 3:
Last you need to add the area of both the rectangle and the triangle to get the total area of 84 sq meters

A contractor is tiling your bathroom with one-foot square tiles. How many tiles are needed for the job? PLS HELPPP
Answer:
Depends on the bathroom
Step-by-step explanation:
Basically since I don't know the bathroom length and width, Ima just cut it down for you.
It is your bathroom area (length*width) divided by the area of the tiles, which is 1*1=1 foot^2(square)
Also it depends on the unit you used for the bathroom, you gotta transfer the unit for the bathroom length and width into feet.
So you should get number for bathroom area with the unit feet square.
Can someone explain how linear function is used in math and how it works

Solve this equation until you have the squared variable for the missing side length on one side of the equal sign and a rational number on the other.
The solution of the equation 9² + 12² = c² will be 15 and negative 15.
What is the solution to the equation?A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The equation is given below.
9² + 12² = c²
Simplify the equation, then the value of the variable c will be
c² = 81 + 144
c² = 225
c = ±√225
c = ±√(15)²
c = ± 15
Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.
More about the solution to the equation link is given below.

A health club charges a $50 initial fee plus $2 for each visit. Moselle has spent a total of $144 at the health club this year . Use an equation to find how many visits she has made
Answer:
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y-intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Moselle made 47 visits to the health club.
