So, here’s a math question for you: suppose you set your confidence level at "i think i know it," which means that you’re initially risking 80 points. you guess wrong on the first attempt. how many "second-chance" points will you be able to earn back?

The answer is 20 points

Step-by-step explanation:

If the points is based on 100 by rating, and your confidence level of 'I think I know it' places you on the initial risk of 80 points as suggested, which eventually places you on the wrong side, you will be left with the following:

Total rating point of 100 minus initial risking points of 80. This leaves you with a second chance points of just 20.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
