You know that a number divided by itself is 1, so this is

\dfrac{7^{-1}\times 7^{-7}}{7^{-7}}=7^{-1}\times\left(\dfrac{7^{-7}}{7^{-7}}\right)\\\\=7^{-1}\times 1=7^{-1}=\bf{\dfrac{1}{7}}

Something to a negative power is the reciprocal of that thing to the opposite positive power.

When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)

When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)

So your answer would be 7^(-1).
Hopefully my explanation was clear?

3 2 ? start fraction, 2, divided by, 3, end fraction of the doughnuts in a box have frosting. \dfrac12 2 1 ? start fraction, 1,
timurjin [86]

Answer:

\frac{1}{3} of the doughnuts in the box have frosting and sprinkles.

Step-by-step explanation:

If there are x doughnuts in the box. Then, \frac{2}{3} \times x = \frac{2x}{3}  of the doughnuts in the box have frosting. Therefore, \frac{1}{2} \times \frac{2x}{3} = \frac{1}{3}x of the doughnuts with frosting have sprinkles. This implies that \frac{1}{3} of the doughnuts in the box have frosting and sprinkles.

Write a recursive rule and a explicit rule for the sequence I really need help
Shalnov [3]

Answer

y = 6x

Explanation

To write a recursive or explict rue for this sequence, we need to firstly examine the given sequence.

If we let money spent = y and number of weeks = x

when x = 1, y = 6

when x = 2, y = 12

when x = 3, y = 18

when x = 4, y = 24

We can easily see that as x increases by units of 1, the y increases by corresponding units of 6.

A rule that will work for this is that

y = 6x

so that, when x = 1, y = 6(1) = 6 (as it is on that graph)

when x = 2, y = 6(2) = 12 (as it is on that graph again)

And so on.

Hope this Helps!!!

Circle A has a circumference of
lilavasa [31]

#Circle A

\\ \bull\tt\longmapsto 2πr=16

\\ \bull\tt\longmapsto 2(3.14)r=16

\\ \bull\tt\longmapsto 6.28r=16

\\ \bull\tt\longmapsto r=\dfrac{16}{6.28}

\\ \bull\tt\longmapsto r=2.6units

#Circle B

\\ \bull\tt\longmapsto πr^2=25

\\ \bull\tt\longmapsto r^2=\dfrac{25}{π}

\\ \bull\tt\longmapsto r=\sqrt{\dfrac{25}{π}}

\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{π}}

\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{3.14}}

\\ \bull\tt\longmapsto r=\dfrac{5}{1.74}

\\ \bull\tt\longmapsto r=2.94units

Circle B has bigger radius
