Step 1: Add 65 to all sides
Step 2: Add 4x to all sides
Step 3: subtract 70 to all sides
Step 4: divide by 4 to all sides
Ending: x is greater than or equal to -17.5
You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...
No solution because the inequality that you end up with won't make sense and therefore does not work in the problem
Answer: NO SOLUTION (yayayyayay).
First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
It would be D because the formula is: pi r^2
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.
