Twelve people can build 30 chairs in 8 hours. How many chairs can be built in 100 hours

375 Chairs.

Step-by-step explanation:

The Twelve People Do Not Matter.

30 Divided By 8 = 3.75

You might say, You cant build 3/4 of a chair! but when you multiply, it makes sense.

3.75 Times 100 =  375

375 Chairs Can Be Built In 100 Hours.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
