Evaluate 3^2*5^5*3^3*5^3/3^4*3^4

Lina20 [59]

$\frac{{3}^{2} \times {5}^{5} \times {3}^{3} \times {5}^{3} }{ {3}^{4} \times {3}^{4} } \\ = \frac{ {3}^{5} \times {5}^{8} }{ {3}^{8} } \\ = \frac{ {5}^{8} }{ {3}^{3} } \\ = \frac{390625}{27} \\ = 14467.592592......$

This is the solution.

Plz help me with all 4 questions this is worth 10

vfiekz [6]

Hello! I can help you with this! It asks for a ratio, so we have to solve it in that format. Although, there are different ways of solving it.

1. Okay. So a ratio for this would be 3/4 : 5/6. To divide fractions, we must keep the first fraction the same, change the division into a multiplication symbol, and flip the second fraction over. So it would look like this: 3/4 * 6/5. Multiply straight across (n*n/ d*d). When you do that, you get 18/20 or 9/10 in simplest form. The landscaper's rater is 9/10 acres per hour.

2. The ratio for this question is 9/4 : 1/2 For the next question, we repeat the steps for dividing fractions. Keep, Change, Flip. 9/4 * 2/1 is 18/4 or 4 1/2 in simplest form. Sally's running speed is 4 1/2 miles per hour.

3. Okay. Going back to question #1, the unit rate was 9/10 acres per hour. All we have to do now is multiply that number by 4. To multiply fractions, do it straight across. 9/10 * 4/1 is 36/10 or 3 3/5 in simplest form. A landscaper can mow 3 3/5 acres in 4 hours.

4. Then we repeat the steps done in question #3, and incorporate it in this problem. Going back to question #2, the unit rate was 4 1/2 miles per hour. All we have to do is multiply by 3. 9/2 * 3/1 is 27/2 or 13 1/2 in simplest form. Sally can run 13 1/2 miles in 3 hours.

The results of a recent survey of 1500

ddd [48]

Answer:

A) <u>7 : 13</u> is the ratio .

B) <u>69.65 million </u>approve of George W. Bush.

Step-by-step explanation:

Given:

The results of a recent survey of 1500 American adults show that 525 approve of the job that President George W. Bush is doing and 975 do not approve.

Now, to find the ratio of the people approve to those that do not. And number of people approve of George W, if there are 199 million adults in the United States.

People approve of the job = 525.

People do not approve of the job = 975.

So, the ratio of that approve to those that do not:

$525:975$
