Answer:
1.25 because when in a calculator i add 1.25% i subtract 300 and that is all that is left.
Answer:
80 students decided to take a vanilla cupcake.
Step-by-step explanation:
100 * 0.80 = 80
In a direct proportion, the equation can be set up as
y = kx
k = y/x
k = 6/20
k = 0.3
We have a bunch of rectangles making up the lateral sides of this figure. They have side length 12 and height 13.
So the area of one rectangle is 12 x 13 = 156.
We have 6 of these rectangles, so our lateral area is 6(156) = 936.
The total surface area requires that we include the area of the base. To find the area of a regular polygon we take half of the product of the apothem and perimeter.
A = (1/2)*a*p
The apothem is given to be 10.39,
and the perimeter is fairly easy to calculate:
With the side length being 12, the perimeter is then 6(12) = 72.
So then the area of our base is (1/2)*10.39*72 = 374.04
So then the total surface area is the (base area) + (lateral area),
374.04 + 936 = 1310.04
