A 30 Oz box of Lucky Charms cost $4.50 a 20 oz box cost $3.60 what is the unit price of each box
notka56 [123]

We need to find the unit price of each box.

So, a box that weighs 30 Oz costs $4.50.

lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.

Unitary method is a process to find the value of a single unit.

Now,

30 Oz costs $4.50

therefore, 1 Oz should cost:

\frac{4.50}{30} =0.15 dollars

So, the unit price of box 1 is $0.15.

Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.

Now,

20 Oz box costs $3.60

therefore, 1 Oz should cost:

\frac{3.60}{20} =0.18 dollars

So, the unit price of box 2 is $0.18.

QuestionA local road rises 30 feet for every 483 feet of highway. What is the slope of the highway?
max2010maxim [7]

The slope can be found by the "rise over run", that is, is the change in variable y divided by the change in variable x.

In this question,

\begin{gathered} slope=\frac{rise\text{ in the road}}{run\text{ in highway}} \\  \end{gathered}

Substituting the values:

\begin{gathered} slope=\frac{30}{483} \\ slope=0.06\text{ feet per feet of highway.} \end{gathered}

Answer: 0.06 feet per feet of highway.

How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a
Nuetrik [128]

Answer:

40 quarts.

Step-by-step explanation:

Let x =quarts of the 50% solution

so, according to the question

the typical mixture equivalent equation will be like this

.50x + .20(20) = .40(x+20)\\.50x + 4 = .40x + 8\\.50x - .40x = 8 - 4\\.10x = 4\\x = 4/.10 \\x = 40

so the answer will be 40 quarts of 50% solution should be added.
