Jada eats 2 scoops of ice cream in 5 minutes. noah eats 3 scoops of ice cream in 5 minutes. how long does it take them to eat one scoop working together ( if they continue eating ice cream at the same rate they do individually)?

minutes

Step-by-step explanation:

Let's find unit rate of each.

Jada

2 scoop in 5 minutes

So,

1 scoop in 5/2 = 2.5 minutes

Noah

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

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
