Answer:
D
Step-by-step explanation:
If you put a line down the middle of d and fold it in half it will be the same on both sides.
Answer:
or
Step-by-step explanation:
Subtract 7 from both sides:
Subtract 10x from both sides:
Divide both sides by -5:
or
81 x 31 = 2 511 (area of a brick)
2511 x 400 = 1 004 400 (area of the wall)
Convert 1 004 400" to ft. [1ft. = 12"]
1 004 400 / 12 = 83 700 ft.
Now this is what we have.
-Hight 42 ft.
-Length X ft.
-Area 83 700ft.
Algebra time.
42 x X = 83 700 (to get X you would devide 83 700 by 42)
83 700 / 42 = 1 992.85ft. (X = 1 992.85ft.)
So the length of the wall would be 1992.85ft.
294 cm^2 = 6 * r^2 (the cube has 6 faces)
so the radius is 7 cm
the volume is 7^3 cm^3 = 343 cm^3
