A classroom is arranged with 8 seats in the front row, 10 seats in the middle row, and 12 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom. What is the probability that the first student who enters the classroom will be assigned a seat in the front row?

4/15

Step-by-step explanation:

Given 8 seats in the front row

10 seats in the middle row and 12 seats in the back row

Total number of seats = 8 + 10 + 12

= 30

Probility that the firstborn student who enters the class is assigned a seat in the first row is

No. of seats in the first row/ total number of seats in the classroom

That’s 8/30

4/15

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.
