1/9
because there are 21 chips in the bag 7 of them are yellow so 7/21
but you draw twice so you square it (7/21)^2=1/9
The equation of any circle is
(x - a)^2 + (y - b)^2 = radius^2 where our center is (a, b)
Therefore, our equation is as follows.
(x + 2)^2 + (y - 3)^2 = 16
Answer:
Straight Angle
Explanation:
Def: An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees. Def: A straight angle is an angle whose measure is exactly 180 degrees. Def: Two angles are congruent if their measures are exactly the same. Def: Two angles are complementary if their measures add up to 90 degrees.
Answer: 50.27
Step-by-step explanation:
Area = pi r^2
= pi x 16
The temp decreased by 2.25 degrees fahrenheit from the beginning to the end of the 3- hour period.
