The answer is 12
48 - 36 = 12
Answer:
40
Step-by-step explanation:
The median is the middle number
There are 10 numbers
The middle is between 5th and 6th number
Take the 5th and 6th numbers and average them
(39+41)/2 = 80/2 = 40
The median is 40
Answer:
C. Add 9 to both sides of the equation.
Step-by-step explanation:
Given
Required
Complete the squares
We have:
---------------------------------------------
Take the coefficient of -6 i.e. -3
Square it (-3)^2 = 9
Add 9 to both sides
---------------------------------------------
<em>Hence, C is correct</em>
Note that the interior angles must add up to 180 degrees: 50+62+m<C = 180.
Then 112 + m<C = 180, so that m<C =68 degrees.
Use the Law of Sines to find the value of a, as follows:
sin 50 deg sin 62 deg
-------------- = ----------------
a 31 cm
31sin 50 31(0.766)
Then 31sin 50 = a*sin 62, and a = --------------- = ---------------- = 26.9 cm
sin 62 0.883
a =
