Answer:
1. cm
2. 318.198 ft^2.
Step-by-step explanation:
Hmm. Very stuck. We'll just take it slow. :)
For the first one, we'll just square the bottom of the parallelogram, because
it's a square. The answer is above.
The second is a bit more complicated. The formula for the area of a parallelogram is (base) x (height)= A(area), but that will be of no use until we know the height (the dashed line on the left).
So, do let's go about finding the height with a 45-45-90 triangle.
The way these work is that the two short sides are equal to x, and the longer one is . So, in essence, .
15/=10.61
Both of the other two sides (one being the height) are 10.61 ft long.
Multiply that by 30:
30 x 10.61= and you get 318.198 ft^2.
Answer: -12 - 3 = -15
Explanation:
We start at -12 which goes in the first box.
Moving to the left 3 units means we subtract off 3, so that's why 3 goes in the second box.
The arrow is pointing at -15 as the final destination, which goes in the final third box.
Answer:
0.254
Step-by-step explanation:
Table A-6 will be shown below for reference. Since none of the answer choices contain the critical value for 61, we can just round that number to 60. We will see that the critical value is 0.254. If you're having trouble reading the table below, look at the columns to find the corresponding significance level you are working with then find the sample value.
Best of Luck!
