Donations = $10,000
Revenue = $55 per race enry
Expense = $15 per race entry
Budget ≥ $55,000
Let x = the number of race entries.
Total revenue = Donations + Race entries - Expenses
Therefore
10000 + 55x - 15x ≥ 55000
40x ≥ 45000
x ≥ 1125
Answer: Race entries ≥ 1125
B and C (I think they are the same)
Answer:
24
Step-by-step explanation:
3x - 14 + 6 - 4 - 2x = 12 => 3x -12 - 2x = 12 => x = 24
÷
is the equation
When dividing fractions, you "flip-flop" and multiply
So what that means is that you flip the second fraction and multiply
So
is now
Now the equation is
×
which equals
Your answer is
Answer:
3 boxes
Step-by-step explanation:
First, we need to find the area of the whole square, so we can find out how much to subtract from. We can easily do this by multiplying 16 by 16, since it is a square.
16*16=256 square feet.
Now, we just need to find the area of the circular rug, and subtract it from 256 to find the area not covered by the rug that needs to be tiled. Since the sides of the rug touch each side of the floor, than the diameter will be the same as the side length of the square. Thus, the diameter is 16.
Now we can use the equation <em>A=pir^2 </em>or <em>Area=pi*radius squared</em> to find the area of the circle. The radius is halve of the diameter, so divide 16 by 2 to get the radius, or 8. Now all we have to do is square 8 and multiply it by 3.14.
8^2=64
Now multiply.
64*3.14=200.96.
The area of the circle is 200.96, so subtract 200.96 from 256.
256-200.96=55.04.
So they will need 3 boxes to cover the area left.
Hope this helps!
