Which expression is equivalent to 3^4 ⋅ 3−^9?

Answers

Answer:

3^-5 = 1/3^5

Step-by-step explanation:

3^4 ⋅ 3−^9

When multiplying exponents and the bases are the same, we can add the exponents

a^b * a^c = a^ ( b+c)

3^4 ⋅ 3−^9

3^( 4-9)

3^-5

We know that a^ -b = 1/a^b

3^-5 = 1/3^5

Is 4 - -9 positive or negative?
positive
negative

Answers

Answer:

Positive

Step-by-step explanation:

Remember that when we have two negatives, they cancel each other out and become positive.

4 and 9 are both positive. The sum of two positive numbers is always positive.

Thus, the answer is positive.

A store owner paid $120 wholesale price for a suit. He needs to make a 35% profit on
the sale of the suit. By how much should he markup the price of the suit to make his desired profit?

Answers

Answer:

The answer to that is $78.00 and you save $42.00

Step-by-step explanation:

All you have to do in this problem is, figure out what is 35% of $120.  A product that normally costs $120 with a 35 percent discount will cost you $78.00, and you saved $42.00. You can also calculate how much you save by simply moving the period in 35.00 percent two spaces to the left, and then multiply the result by $120 as follows: $120 x . 35 = $42.00 savings.

Mark up price for earned desired profit is $162

Desired profit based question:

Given that;

Amount paid by owner = $120

Desired profit = 35%

Find:

Mark up price for earned desired profit

Computation:

Mark up price for earned desired profit = 120(1 + 35%)

Mark up price for earned desired profit = 120(1 + 0.35)

Mark up price for earned desired profit = 120(1.35)

Mark up price for earned desired profit = $162

A $30 pair of jeans is on sale for $15. What is the percent of change for the pair of
jeans?

Answers

Answer:

50%

Step-by-step explanation:

All we need to do is find out what percent 15 is compared to 30. So think of 30 as "100%" in this case. We know it's on sale and selling for $15 so all we need to do is figure out what $15 is compared to $30.

30 ÷ 15 = 15.

Luckily in this case 15 is half of 30. So half of "100" would be 50. 50%.

50% is your answer.

Hope this helps and have a nice day!
