Answer:
Step-by-step explanation:
- Initial amount that was received from the garage sale = x
- Spent on bicycle = 1/2x
- Spent on portable stereo set = 1/2(1/2x) = 1/4x
<u>Money left: </u>
- 1/2x - 1/4x = 80
- 1/4x = 80
- x = 4*80
- x = 320
Initial amount was $320
Correct choice is B
The product of a rational number multiplied by itself is called as a perfect square.,we can easily find out the square root for a number which is a imperfect square
Step-by-step explanation:
using the following formula we can find a square root for a number which is a imperfect square
X = Non perfect square
√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )
Example
√38
the nearest perfect root is 36
36 (√36=6)
so √38 = √36 + (38-36)/2√36
= 6 + 2/12
=6 + 1/6 = 6.166 (answer)
To find critical points of a function, first calculate the derivative. Remember that critical points must be in the domain of the function. So if x is undefined in f(x), it cannot be a critical point, but if x is defined in f(x) but undefined in f'(x), it is a critical point.
If it’s all 3 being chosen it’s 1/7 X 1/7 X 1/7 which is .002915 which would be a .29%
