Answer:
- 6 ft per flip
- 14 ft from A to B
Step-by-step explanation:
<h3>a.</h3>
If we assume that the first two flips are to the right, for some flip distance f, Croakie will land at ...
B = A + 2 +2f
He will land back at A (the origin) after 1 flip and a slide of 8 ft to the left:
B -f -8 = A
Subtracting A from both equations and substituting for B-A, we have ...
B -A = 2 +2f
B -A -f -8 = 0
(2 +2f) -f -8 = 0 . . . . substitute for (B-A)
f -6 = 0 . . . . simplify
f = 6 . . . . . add 6
The length of a flip is 6 feet.
__
<h3>b.</h3>
B -A = 2 +2f = 2 +2(6) = 14
The distance between A and B is 14 feet.
2012+46* 2/4 - 6/7 = 2014.14
Hope this Helped!

Answer: ![SA=117.2\ in^2](https://tex.z-dn.net/?f=SA%3D117.2%5C%20in%5E2)
Step-by-step explanation:
You need to remember the following:
1. The area of a rectangle can be calculated with the following formula:
![A_r=lw](https://tex.z-dn.net/?f=A_r%3Dlw)
Where "l" is the length and "w" is the width.
2. The area of a triangle can be calculated with the following formula:
![A_t=\frac{bh}{2}](https://tex.z-dn.net/?f=A_t%3D%5Cfrac%7Bbh%7D%7B2%7D)
Where "b" is the base and "h" is the height.
Use those formulas to find the area of each face.
<u> Area of the rectangle</u>
![A_r=(10\ in)(4\ in)=40\ in^2](https://tex.z-dn.net/?f=A_r%3D%2810%5C%20in%29%284%5C%20in%29%3D40%5C%20in%5E2)
<u>Area of two triangles</u>
There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:
![A_{t1}=A_{t2}=\frac{(10\ in)(5\ in)}{2}=25\ in^2](https://tex.z-dn.net/?f=A_%7Bt1%7D%3DA_%7Bt2%7D%3D%5Cfrac%7B%2810%5C%20in%29%285%5C%20in%29%7D%7B2%7D%3D25%5C%20in%5E2)
The areas of the other two triangles (which are equal) are:
![A_{t3}=A_{t4}=13.6\ in^2](https://tex.z-dn.net/?f=A_%7Bt3%7D%3DA_%7Bt4%7D%3D13.6%5C%20in%5E2)
Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:
![SA=40\ in^2+25\ in^2+25\ in^2+13.6\ in^2+13.6\ in^2\\\\SA=117.2\ in^2](https://tex.z-dn.net/?f=SA%3D40%5C%20in%5E2%2B25%5C%20in%5E2%2B25%5C%20in%5E2%2B13.6%5C%20in%5E2%2B13.6%5C%20in%5E2%5C%5C%5C%5CSA%3D117.2%5C%20in%5E2)
Hey there! :)
Answer:
A. 108 ft².
Step-by-step explanation:
Find the area of each face using the dimensions 4, 3 and 6. Remember, there are 6 total faces with 3 sets of congruent faces. The faces are rectangular, so the formula A = l × w will be used to solve for the area of each:
2(4 ·3) = 2(12) = 24 ft²
2(4· 6) = 2(24) = 48 ft²
2(3 · 6) = 2(18) = 36ft².
Add up the areas of the faces:
24 + 48 + 36 = 108 ft².
