Step-by-step explanation:
Maybe she had
128 + 9 = 137 buns
Subtract 6.7 from 20. This is 13.3. Divide 13.3/5 is 2.66. That is the answer
Cross section is a surface that is exposed after slicing or making a cut through an object. If a hexagonal pyramid is cut horizontally then the cross section should be an hexagon as well since the base is a hexagon. However, when it is cut vertically the resulting shape would be a triangle.
Answer:
The width of the garden is 100 feet.
Step-by-step explanation:
The formula for the perimeter of a rectangle is 2(L+W) where L = length and W = width.
Since we know the perimeter (the fence that surrounds the garden) is 820 feet and the length of the pen is 10 feet longer than 3 times its width, we can set an equation and solve for the width:
L = 10 + 3W
So substitute 10 + 3W for L in the equation:
2[(10 + 3W) + W) = 820
2(10 + 4W) = 820
10 + 4W = 410
4W = 400
W = 100
Therefore, the width of the garden is 100 feet.
Answer:
n = -6 or n = 4.
Step-by-step explanation:
-3 | -8n – 8 | = -120
Divide both sides by -3:
| -8n – 8 | = 40
This gives us 2 equations because the expression in the absolute signs can be positive or negative:
-8n - 8 = 40
so -8n = 48
n = -6.
and
-8n - 8 = -40
-8n = -32
n = 4.
