2.74x7.5=20.55=20.550
That's all of your answers.
Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
What is the value of X?
Simplify:
8x - 10 - 4x = - 12(12x - 20)
Simplify both sides:
8x - 10 - 4x = - 12(12x -20)
8x + - 10 + - 4x = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x + - 10 + - 4x = 144x 240
(8x + - 4x) + ( -10) = - 144x + 240 (Combine Like Terms:)
4x + - 10 = - 144x + 240
4x - 10 = - 144x + 240
Add - 144x to both sides:
4x - 10 + 144x = - 144x + 240 + 144x
148x - 10 = 240
Add 10 to both sides:
148x - 10 + 10 = 240 + 10
148x = 250
Divide both sides by 148
148x/148 = 250/148
x = 125/74
Answer: x = 125/74 (Decimal: 1.689189)
Hope that helps!!!!
The answer is 3 ft
The surface area (SA) of a cylinder with radius r and height h is:
SA = 2πr² + 2πrh = π(2r² + 2rh)
We have:
SA = 126π ft²
h = 3 * d
d = 2r
h = 3 * 2r = 6r
126π = π(2r² + 2rh)
126 = 2r² + 2rh
126 = 2r² + 2r * 6r
126 = 2r² + 12r²
126 = 14r²
r² = 126/14
r² = 9
r = √9
r = 3
