Answer:

\frac{1}{125}

Step-by-step explanation:

1.apply \: exponent \: rules :   \frac{ {x}^{a} }{ {x}^{b} }  =   {x}^{a - b}

=  {5}^{4 - 7}

2.subtract \: the \: number : 4 - 7 =  - 3

=  {5}^{ - 3}

3.apply \: exponent \: rule :  {a}^{ - b}  =  \frac{1}{  {a}^{b}  }

=  \frac{1}{ {5}^{3} }

4. \:  {5}^{3}  = 125

=  \frac{1}{125}

Anastasy [175]

Here in the given equation, 3x + 8 the term 8 represents the weight of the empty bucket.

Its given that the number of marbles is x, and the weight of each marble is same which is 3. So, total weight of marbles is 3x.

Now, if 3x + 8 is the weight of the bucket and marbles, then 8 represents the weight of the empty bucket.

Line AB is tangent to circle O at B. Find the length of the radius r for AB = 8 and AO = 11.7. Round to the nearest tenth if nec
Pepsi [2]

Answer:

8.5

Step-by-step explanation:

So the line segment that is tangent to the circle is 8, and AO is 11.7.

When you connect them, they are perpendicular, so you have a right triangle with one unknown leg that we will call X, a leg that is 8, and a hypotenuse that is 11.7.

If you use the Pythagorean Theorem, you will find that the leg is √72.89, which is approximately 8.5.

That leg is the radius.

This might be wrong so check it.
