Asquare has a perimeter of 36 inches. how long is each side?
4 inches
6 inches
9 inches
12 inches

Step-by-step explanation:

You answer is 9

9 inches

Step-by-step explanation:

Square's have 4 sides. Each side of that square is equal. To find the length of each side you would simply have to do:

36 ÷ 4

Therefore, 36/4 equals 9. Each side equals 9, adding up all for together to come up with the perimeter, 36.

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

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
