Ana uses 3/4 cup of china juice for every 1/3 cup of lemon juice to make a soda. What is the ratio of cups of china juice to cups of lemon juice?

<u>Solution</u>

To find the ratio of cups of china juice to cups of lemon juice, we divide

\frac{3}{4}

by

\frac{1}{3}and simplify.

We set up the division as follows:

\frac{3}{4}  \div  \frac{1}{3}

Multiply the first fraction by the reciprocal of the second fraction.

\frac{3}{4}  \times  \frac{3}{1}

This gives us;

\frac{3 \times 3}{4 \times 1}

We then obtain:

\frac{9}{4}

Therefore the ratio of cups of china juice to cups of lemon juice is 9:4

Based on the NYC Department of Health Community Health Survey in 2010, a 95% confidence interval for the proportion of New Yorke
g100num [7]

Answer:

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Step-by-step explanation:

The lower bound of the confidence interval is 29.9%.

So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.

Out of 6 million, that is:

0.299*6000000 = 1,794,000

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Simplify the expression. Rewrite using only positive exponents.
Dvinal [7]

The simplified form of the given expression is x^{18}a^{3}b^{3}.

The given expression is (\frac{x^{4}a^{2}b^{3} }{x^{-2}ab^{2}} )^{3}.

We need to simplify the given expression.

<h3>What are the basic laws of exponents?</h3>

The basic laws of exponents are as follows:

a^{m} \times b^{m} =(ab)^{m}

a^{m} \div b^{m} =(\frac{a}{b} )^{m}

a^{m} \times a^{n} =(a)^{m+n}

a^{m} \div a^{n} =(a)^{m-n}

Now, (\frac{x^{6}a^{2}b^{3} }{ab^{2}} )^{3}=(\frac{x^{18}a^{6}b^{9} }{a^{3}b^{6}} )

=x^{18}a^{3}b^{3}

Therefore, the simplified form of the given expression is x^{18}a^{3}b^{3}.

A video-game designer is using the expression 6n^3 in a program to determine points earned, where n is the game level. Simplify
Vsevolod [243]

Answer: 6n^6

Step-by-step explanation:

For this exercise you need to remember the Power of a power property. This states that:

(a^m)^n=a^{mn}

You know that the given expression 6n^3 is used to determine points earned, and "n" represents the game level.

Therefore, knowing this, you can to substitute n^2  into the expression 6n^3:

6(n^2)^3

Finally, in order to simplify the expression for the n^2 level, you must apply the Power of a power property mentioned before.

Therefore, you get:

6(n^2)^3=6n^{(2*3)}=6n^6
