Ex. 2 - Here are the grades you received this year: test grades (90, 79, 84), quiz grades (100, 49, 82, 73), classwork grades (100, 100, 100, 80), homework grades (45, 95), and you received an 82 on your final
exam. What would your overall grade be in Mr. Brown's class?
I

82.8

Step-by-step explanation:

To find the mean or the average of the numbers, add up all the numbers then divide by how many there are. the total number in this problem is 1159 then you can now divide it by 14 which will give u 82.78 or 82.8.

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.
