Answer: 12 it’s not that hard it’s subtraction 18 - 30 = 12
100% ............. 2.20
40% ............. x
-----------------------------
x=40*2.20/100
x=88 / 100
x= 0.88
The answer is x=0.88

Step-by-step explanation:
Question 2: The answer is A. 90, 45, 45 because one angle is a right angle which is always 90 degrees and the two remaining angles are the same. Also, all triangles have to have a total amount of 180 degrees when all angle-degree-measurements are combined, which leaves A as the only possible answer.
Question 3: The answer is D. To solve this question you simply multiply all the dimensions of the triangular prism together. That would be: 10 x 14 x 8 = 1,120 in squared
Question 4: Sorry, didn't get this one :(
Question 5: The answer is B. 4pi. Sorry, don't have a good explanation for this one, but I'm pretty sure it is correct.
Question 6: Can't see the question, so I can't help you :(
Question 7: The answer is A. 5 feet. Using the power of elimination you can conclude that the three other options to the answer are improbable.
Question 8: The answer is B. 180 - x. To get this you need to know that 180 degrees is a flat line angle. Since angle x and angle y stem from the same two flat lines intersecting diagonally, you can determine the 180 - angle x would equal angle y.
