$160

Step-by-step explanation:

remaining money= 40% x $400= 160

see explanation

Step-by-step explanation:

100 percent -60 percent =40 percent

rest money =40 percent of $400

=40/100×$400

=$160.

: the rest many needed by the student is $160.

32

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
