Answer:

\frac{1}{{1000x^3}}.

Step-by-step explanation:

You are trying to find (10x)^{-3}.

When a number has a negative exponent, that means that the number becomes a fraction. That sounds confusing, so let me show you what that would be...

\frac{1}{(10x)^{3} }

And since the 10x is being raised to the third power, it is the same thing as saying 10^3 * x^3. So, you would have...

\frac{1}{{10^3x^3}}

= \frac{1}{{10 * 10 * 10 * x^3}}

= \frac{1}{{1000x^3}}

And that's your answer!

Hope this helps!

OK so there is a total of thirty five hours so multiply thirty five by sixty since there is sixty minutes in one hour which once thirty five and sixty are multiplied it is two thousand one hundred so you divide by ten because each performance took ten minutes and the hours were already turned into minutes so after dividing you her two hundred ten.

Janice's mother gave her 10. Dollars to buy 5 pounds each pounds of bananas and apple she got there that bananas were 80c Per po
viva [34]
Total money Janice has: $10, so the total cost for the bananas and apples must be less than or equal to $10. 

Keeping this in mind, let's break this problem down.
1: The bananas: She needs 5 pounds of bananas, which cost $0.80 per pound. To find the total cost of bananas, multiply the cost by the number of pounds.
5($0.8)=$4. 

2. The apples: She also needs 5 pounds of apples at $1.40 per pound. To find the total cost, follow the same process as with the bananas:
5($1.4)=$7 for the total cost of the apples.

3. Now you have two separate costs: one for apples, and the other for bananas. Combined, the total cost is 4+7=11. Because Janice's mother only gave her $10, she's short a dollar. So no, she doesn't have enough money.
