60 [tex]ft^{2}[/tex]
Step-by-step explanation:
To find the surface area, you need to find the area of all the shapes that make up the pyramid and add them all together.
The area of the square is simply 36 [tex]ft^{2}[/tex], as it is the length times itself (6x6)
To find the area of a triangle, it is bh/2, where b = base, and h = height. The height is 4 ft, and the base is 6 ft as the length of the square is the same as the base of the triangle. (4x6)/2 = 12.
The area of one of the triangles is 12, and they are all identical and there is 4 of them, so 12 x 4 = 48.
Add that to the area of the square:
48 + 12 = 60
4 triangle faces
1 square
Area of square = length x length in this case 6 x 6 which is 36.
Triangle area = 1/2Bh in this case 1/2 x 6 (4) which is equal to 12.
Now since we have four triangle faces let’s multiply 12 by 4 —> 48.
Add the square to the triangle faces —> 48+36= 84ft^2.

0.5 x 80 + 0.3x = 0.4(80 + x)
Find 2x.
Answers
Answer:
160
Step-by-step explanation:
0.5 x 80 + 0.3x = 0.4(80 + x)
0.5 x 80 + 0.3x = 32 + 0.4x
40 + 0.3x = 32 + 0.4x
-32 -32
8 + 0.3x = 0.4x
- 0.3x -0.3x
8 = 0.1x
/0.1 /0.1
80 = x
2x so... 2(80)... 2x = 160
40-32=0.4x-0.3x
8=0.1x
80=x
2x=160

Answers
Answer:
$570
Step-by-step explanation:
If she marks up the sofa for 90%, she will change the price to 760$
Now, 25% of 760$ is 190$. So, we subtract 190 from 760 and get 570$

1005.3 [tex]ft^{3}[/tex]
Step-by-step explanation:
V=π r^2 h = π · 42· 20 ≈ 1005.30965 ---> 1005.3
Answer:
the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.
So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.
Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.

(C)a)6
i didnt know how to do b
Step-by-step explanation:
it is bcz 99÷16 is 6
Answer:
(a) 3 rows had 16 chairs.
(b) 3 rows had 17 chairs.
Explanation:
There must be 6 rows, which is constant.
Make equation's:
1st equation: 16p + 17w = 99
2nd equation: w + p = 6, w = 6 - p
Solve by substitution:
⇒ 16p + 17(6 - p) = 99
⇒ 16p + 102 - 17p = 99
⇒ -p = -3
⇒ p = 3
Then find w, w = 6 - p = 6 - 3 = 3
Hence, there is 3 rows of 16 chairs and 3 rows of 17 chairs.
Try to match match and confirm the answer:
17 × 3 + 16 × 3 = 99 chairs in 6 rows(PLS HELP HURRY MY TEACHER NEEDS ME TO PASS THIS!)
