The weekly production costs at Jessica’s T-Shirt Shack are given by the algebraic expression 75 + 7s + 12t where s
represents the number of short-sleeve shirts produced
during the week and t represents the number of long-sleeve
shirts produced during the week. Find the production cost
for a week in which 30 short-sleeve and 24 long-sleeve
shirts were produced.

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

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
