A road crew is putting sign on a 5 mile Road the first sign is the start of the road then they will place a sign every 500 yards how many sign do they need

17

Step-by-step explanation:

There are 5,280 feet in a mile you want to multiply that by 5 for 5 miles

(5,280) (5) = 26,400

Since there are 3 feet in a yard you want to divide this number by 3

26,400/3 = 8,800

Then divide this by 500 for every 500 yards

8,800/500 = 17.6

Then round down because you can't have a decimal.

Therefore it is 17

right

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
