At D.J.s Drink stand Erika ordered a cup of fruit punch made using 1/4 cup of lemonade 1/12 cup of cranberry juice. What fractio

Zepler [3.9K]

The fraction of the orange juice will be 2/3cup.

Why?

Since there is no additional information, let's assume that the fruit punch is made using just three juice fruits, lemonade juice, cranberry juice and the rest is orange juice.

We can calculate the fraction of the orange juice using the following information:

$FruitPunch=\frac{1}{4}Lemonade+\frac{1}{12}Cranberry+Orange\\\\1cup=\frac{1}{4}cup+\frac{1}{12}cup+Orange\\\\1cup-(\frac{1}{4}cup+\frac{1}{12}cup)=Orange\\\\1cup-(\frac{12+4}{4*12})=Orange\\\\Orange=1cup-\frac{16}{48}cup=1cup-\frac{1}{3}cup=\frac{3-1}{3}cup=\frac{2}{3}cup$

Hence, we have that the fraction of the orange juice will be 2/3cup.

Have a nice day!

Slope of -5 2). (3,9)

podryga [215]

Answer:

The slope of the given two points is $m=\frac{7}{8}$

Step-by-step explanation:

Given two points are (-5,2) and (3,9)

To find the slope with these two points

Let $(x_{1},y_{1})$ and $(x_{2},y_{2})$ be the given points

By using Slope Formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{9-2}{3-(-5)}$

$m=\frac{9-2}{3+5}$ ( subtracting and adding the corresponding terms)

$m=\frac{7}{8}$

Therefore slope is $m=\frac{7}{8}$

The slope of the given two points is $m=\frac{7}{8}$
