To get a B in math, Alexandria Pappas must average 80 on five tests. Scores on the first four tests were 84, 76, 83, and 74. What is the lowest score that she can get on the last test and still get a B?

73

Step-by-step explanation:

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

just sum

10 + 10 = 20
