169.99 / 250 = 0.68 or 68%
100 - 68 = 32% discount
Not sure what asking with total price, because tax varies by state.
Answer: 1.4 seconds
<u>Step-by-step explanation:</u>
The equation is: h(t) = at² + v₀t + h₀ where
- a is the acceleration (in this case it is gravity)
- v₀ is the initial velocity
- h₀ is the initial height
Given:
- a = -9.81 (if it wasn't given in your textbook, you can look it up)
- v₀ = 12
- h₀ = 3
Since we are trying to find out when it lands on the ground, h(t) = 0
EQUATION: 0 = 9.81t² + 12t + 3
Use the quadratic equation to find the x-intercepts
a=-9.81, b=12, c=3

Answer:
129.6% profit
Step-by-step explanation:
1)Firstly in order to find the overall profit you take away $2.70 from $6.20 = $3.50
2)The next step is to put the profit over the amount paid = 3.50/2.70 = 35/27.
3)In order to find the percentaage you multiply 35/27 by 100 = 129.629 recurring. This rounded to 1 decimal place is 129.6%
