Answer:
minutes
Step-by-step explanation:
Let's find unit rate of each.
<u>Jada</u>
2 scoop in 5 minutes
So,
1 scoop in 5/2 = 2.5 minutes
<u>Noah</u>
3 scoop in 5 minutes
So,
1 scoop in 5/3 = 1.25 minutes
These are the times. Time and rate are inverses of each other. So the rates of each is:
Jada = 1/2.5 = 0.4
Noah = 1/1.25 = 0.8
Working together, we add the rates and find the time:
(0.4+0.8)*t = 1
1.2t = 1
t = 1/1.2 = minutes
So, they take minutes to eat one scoop, working together
Answer:
The easiest way to find the equation of a parabola is by using your knowledge of a special point, called the vertex, which is located on the parabola itself.
Step-by-step explanation:
If you see a quadratic equation in two variables, of the form y = ax2 + bx + c, where a ≠ 0, then congratulations! You've found a parabola. The quadratic equation is sometimes also known as the "standard form" formula of a parabola.
