Nico won $70 in a drawing contest. he spent 3/8 of the winnings buying more art supplies. how much money does he have left? plz show work and explain your answer.

a.$26.75
b.$35.25
c.$43.75
d.$52.50

The correct amount is C. $43.75

Step-by-step explanation:

In order to find the amount of money that they will have left, start by looking at what fraction of the original winnings they will still have. Since they spent 3/8 of them, we know he has 5/8 left.

So, we can multiply the amount of winnings by the fraction to get the total amount left over.

$70 * 5/8 = $43.75

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
