Answer:
the number to the right of the 7
Step-by-step explanation:
1) We want to find the area of the triangular bases, which means both shown in the net. So, normally we would divide the area by 2 (from the formula), but since we are finding the area of two triangles, that isn't necessary.
A = 8 x 3
2) There are two different sized rectangles here. One that is repeated twice and the other that is on its own. We know that A and C are the same, and if we think about how this net is folded, we can determine that the width of A and C would be 5 cm. For both sized rectangles, the length is 12 cm. For rectangle B, we can see that its width is 8 cm.
A = (8 x 12) + (5 x 12)
3) Now that we have all of the expressions needed to find the surface area, what we need to do is evaluate each of them and add them together to find the total surface area.
Triangles = 8 x 3 = 24
Rectangles = (8 x 12) + (5 x 12) = 96 + 60 = 156
Surface area = 24 + 156 = 180 square centimeters
Hope this helps! :)
The order of selecting the balls is an illustration of permutation and combination
- The possible number of winning numbers is 269724312
- The possible number of winning numbers in order is 32366917440
<h3 /><h3>The possible number of winning numbers</h3>
The given parameters are:
- Total white balls = 69
- Total red balls = 24
The possible number of winning numbers in any order is calculated using the following combination expression
![n = ^{69}C_5 * ^{24}C_1](https://tex.z-dn.net/?f=n%20%3D%20%5E%7B69%7DC_5%20%2A%20%5E%7B24%7DC_1)
This gives
![n = 11238513* 24](https://tex.z-dn.net/?f=n%20%3D%2011238513%2A%2024)
Evaluate the product
![n = 269724312](https://tex.z-dn.net/?f=n%20%3D%20269724312)
Hence, the possible number of winning numbers is 269724312
<h3>The possible number of winning numbers in order </h3>
When order is important, we make use of permutation.
So, we have:
![n = ^{69}P_5 * ^{24}P_1](https://tex.z-dn.net/?f=n%20%3D%20%5E%7B69%7DP_5%20%2A%20%5E%7B24%7DP_1)
This gives
![n = 1348621560* 24](https://tex.z-dn.net/?f=n%20%3D%201348621560%2A%2024)
Evaluate the product
![n = 32366917440](https://tex.z-dn.net/?f=n%20%3D%2032366917440)
Hence, the possible number of winning numbers in order is 32366917440

The complete question in the attached figure
we know that
perimeter=24 ft
[the perimeter of a rectangle]=2*8+2*x-----------> 16+2x
24=16+2x-------> 2x=24-16----------> 2x=8----------> x=4 ft
the answer is
the option C) x=4 ft
