when you simplify this you get 1/16x^8
It's the first answer choice 2,000,000 because of you scientific notation.
Answer:
40 degrees
Step-by-step explanation:
- All internal angles of a triangle add up to 180 degrees.
- A right angle is 90 degrees.
90+50=140
subtract 140 from 180, which is 40 degrees.

Answer:
A. 23 in.
Step-by-step explanation:
Let r represent the radius of the circular disc.
We have been given that a circular disc has an area that measures between 1,650 and 1,700 square inches.
We will use area of circle formula to solve our given problem.
, where r represents radius of circle.
Since the area of given disc is between 1650 and 1700 square inches, so we can set an inequality as:
Dividing our inequality by 3.14 we will get,
Upon taking square root we will get,
Since 23 is between 22.9233 and 23.268031156, therefore, the length of radius of the given disc could be 23 inches and option A is the correct choice.
