Answer:
idk whats the x..........
I think it may be a cylinder
11t=120(12)
11t=1440
t=1440/11
However t is in hours and we want to know days so:
d=(1440/11)/24
d=1440/264
d=60/11
d=5 5/11 days
Answer: 100 i think, but am not sure.
Step-by-step explanation:
The formula for area of a rectangle is A=l*w. Since the area is 84, then you can use the A=l*w formula. 84 = x(x+8) would be the equation to solve for x.
Now, you need to put the equation in standard form. So, x2 + 8x - 84 = 0.
Since you can't solve this quadratic using factoring, you need to complete the square.
To complete the square you need to add 84 to both sides. Now you have x2 + 8x = 84. Take the coefficient for the x term (8) and divide by 2. Now square it. That would be 42, so 16. Now you have x2 +8x +16 = 100.
Factor x2 +8x +16, so (x+4)2 = 100
If you use the square root property, you have x+4 = 10. Therefore, x = 6 (the short side) and 14 is the long side.
Answer:
The answer to your question is: - 7
Step-by-step explanation:
3125 = (- 1 - 18t) ⁵/³
(3125)³ = ( -1 - 18t)⁵
(3125)³/⁵ = - 1 - 18t
125 = - 1 - 18t
125 + 1 = - 18t
126 = - 18t
t = 126 / -18
t = -7
3125³ = 3.0518 x 10¹⁰
![\sqrt[5]{3.0518 x 10¹⁰}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B3.0518%20x%2010%C2%B9%E2%81%B0%7D)
= 125
