Answer: 9
Step-by-step explanation:
circle formula pi x (rsquared)
R =5 (for all circles)
to find area of all circles multiply the area of one circle by 2. Do this because there are 2 circles on the yard, one whole circle and two half circles, making two circles.
so pi times 25=157.08 (roughly the number is rounded up because the decimal does not end)
now subtract this area from the total area of the rectangle to find the remaining area, which we will fill with wood chips. so 200-157.08=42.92 (using the exact decimal value on my calculator for all calculations, I am rounding them in the explanation.) So now we divide this by 5 because a bag of wood chips covers 5 square feet. 42.92/5=8.58, which we round up to 9, so we need 9 bags of wood chips as our answer.
Good Luck
Applying the centroid theorem, the value of x in the given triangle in the figure is: B. 4
<h3>What is the Centroid Theorem?</h3>
The point where the three median of a triangle meet is the centroid. According to the centroid theorem, the centroid is 2/3 of the distance from each midpoint of the opposite sides to each vertex of the triangle.
Based on the centroid theorem, we have:
FY = 2/3(FS)
Substitute
x = 2/3(x + 2x - 6)
x = 2/3(3x - 6)
3x = 2(3x - 6)
3x = 6x - 12
3x - 6x = -12
-3x = -12
x = -12/-3
x = 4 (option B)

Answer:
4 hours
Step-by-step explanation:
Divide the money she wants to make by the amount she makes per hour.
Goal: 28
Hourly: 7
28 ÷ 7 = 4
So she needs to work for 4 hours.
Hope that helped you! :)
