Answer:

\frac{1}{3}

Step-by-step explanation:

Using the rule of exponents/ radicals

a^{-m} ⇔ \frac{1}{a^{m} }

a^{\frac{1}{2} } ⇔ \sqrt{a}

Given

9^{-\frac{1}{2} }

= \frac{1}{9^{\frac{1}{2} } }

= \frac{1}{\sqrt{9} }

= \frac{1}{3}

Use the following algorithm:
andriy [413]

Answer:

First it says that you have to multiply the number x times 2, this will give you 2x as a result. Next you have to build your equation which is 2x=10, when you have an equation like this, you divide the result with the number before x (x=10÷2) your result will be x=5. Now you have to square the result (which is x) to get y, when squaring a number you have to multiply it by itself (depending of how many times it's asking to do so when there's a small number at the upper right corner of your number, that's how many times you multiply it) so if you have to square 5, it should be 5×5 which gives you the result of y being 25.

Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside
maksim [4K]

Answer:

1 1/3 minutes

Step-by-step explanation:

Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside

From the above question, we are to calculate the time at which the gasoline is pumped into the container

Hence:

Time = Number of gallons/Rate

Number of gallons = 4

Rate = 3 gallons per minutes

Hence:

Time = 4 gallons/3 gallon per minutes

Time = 1 1/3 minutes

The time at which the gasoline is pumped into the container is 1 1/3 minutes
