Answer:
Option A. 36
Step-by-step explanation:
Let
x-------> the number of boys
y------> the number of girls
we know that
-----> equation A
-----> equation B
using a graphing tool to solve the system of equations
Remember that the solution is the intersection point both graphs
The solution is the point (36,6)
see the attached figure
therefore
The number of boys is 36
Answer:
5 pi/12
Step-by-step explanation:
To change degrees to radians, multiply by pi/180
75* pi/180
divide the top and bottom by 15
5 pi/12
A rotation 270° clockwise would be equal to a rotation 90° counterclockwise.
Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3

Volume of the paint = πr²h
---------------------------------------------------
Find Volume of the paint in the bucket
---------------------------------------------------
Volume of the paint = 3.14 x 3.5² x 8 = 307.72 in³
---------------------------------------------------
Find the cost of the paint
---------------------------------------------------
1 in³ = $0.05
307.88 in³ = $0.05 x 307.72
307.88 in³ = $15.39 (nearest hundredth)
---------------------------------------------------
Answer: The paint cost $15.39
