Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by

We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:

Divide through by 90

Divide through by 2



84 x .70 = $58.80
Or if you want to do it the long way you can calculate the actual discount (your savings from this purchase first then subtract it from the original price of $84. It`s just easier to figure out what is left (which is 70% of $84).
Answer:
The answer would be (-3,-1/2)
Step-by-step explanation:
To answer this item, we take the differential of the equation and equate to zero.
C(x) = 0.8x² - 256x + 25939
Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160.
Thus, the number of machine to be made in order to minimize the cost should be 160.
The question is incomplete :
However, assume Number of cups of flower 10
Number of flour cups for each pie 1/4
Answer:
8
Step-by-step explanation:
Number of cups of flower = 10
Number of flower cups per crust pie = 1/4 cups
Since, the cups of flower was divided equally into to 5 containers;
Number of flower cups per container :
10 / 5 = 2
Each container has 2 cups of flower each.
1 container was used in making crust pie :
The number of crust pies made is:
Cups of flower in container / cups of flower per crust pie
= 2 ÷ 1/4
= 2 * 4 /1
= 8 crust pies
