Point C is the center of the circle. The measure of angle ACB is 3x + 120. Arc AB measures 65x – 4. Find the measure of arc AB.

katovenus [111]

In a circle The measurement of a CENTRAL ANGLE (vertex C) is equal to the measurement of the arc intercepted:

65x-4 = 3x+120 ===> 62x=124 & x= 2, hence the arc = 2

Which is the value of the expression ((10^4)(5^2)/(10^3)(5^3))^3

dimulka [17.4K]

Answer:

Step-by-step explanation:

Let's set this up to see if we can simplify it a bit:

$(\frac{10^4*5^2}{10^3*5^3})^3$

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:

$(\frac{10}{5})^3$
