Hey there!

Use this formula:

$a^{-b} =\frac{1}{a^{b} }$

Remember this formula.

Now, let's solve the given problem.

$5^{-9} =\frac{1}{5^{9} }$

Hope this helps you!

What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to $\frac{-9}{4}$ and the second fraction to $\frac{-3}{2}$ . (You are dividing a negative by a negative, therefore, your answer would be a positive.

Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it : $\frac{-9}{4}$ × $\frac{-2}{3}$ .

You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it $\frac{18}{12}$ . This, converted to a mixed fraction, makes 1 $\frac{6}{12}$ ., which is the same as 1 $\frac{1}{2}$ . Your answer is the SECOND CHOICE.

In a scale drawing of a house, 1 inch=4 1/2 feet. If the length of a kitchen is 2 1/4 inches on a scale drawing, what is the act

Answer:

10.125 feet.

Step-by-step explanation:

you can use the rule of three to answer this question, the data we have is:

inches feet

1 → 4 1/2

2 1/4 → x

tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.

For this we multiply the cross quantities:

$x=(2\frac{1}{4} )(4\frac{1}{2} )=2.25*4.5=10.125 ft$
