12. Mr. Cox is considering changing his grading formula so that tests and quizzes make up 80% of a students final grade, homework makes
up 15% of a students final grade and class participation makes up 5%
of a students final grade. If a student has a 100% homework average,
a 85% quiz/test average and a 90% class participation average, what
is there final grade under the new grading formula

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

i dont know men
