Answer:
Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.
Step-by-step explanation:
we know that
The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar
The surface area of a rectangular prism (chocolate bar) is equal to
where
B is the area of the base
P is the perimeter of the base
H is the height of he prism
In this problem we have
<em>Find the area of the base</em>
<em>Find the perimeter of the base</em>
<em>Find the surface area</em>
You can choose from 20 students for the first student, 19 for the second, 18 for the third, ..., 14 for the seventh student.
That gives you 20 * 19 * 18 * 17 * 16 * 15 * 14.
That number would allow you to write the students in different order. Since order here does not matter, any group with the same students in any order is the same group, you need to divide by the number of way you can order 7 items. Divide by 7 * 6 * 5 * 4 * 3 * 2 * 1
(20 * 19 * 18 * 17 * 16 * 15 * 14)/(7 * 6 * 5 * 4 * 3 * 2 * 1) = 77,520
Answer: 77,520
Since they are asking for the unit rate in bolts per wing nut, you can think of it as bolts per ONE wing nut.
To figure that out, you can divide 100 bolts by 2 wing nuts to get 50 bolts per wing nut.
I do it when the numbers are to big but that's me
1.001 is the smallest :)))
