3) A tailor, when asked to stitch dresses for a school's annual programme, says he would stitch 25 dresses a day and finish the work in 20 days. If the school requests him to
finish and deliver the dresses 5 days earlier, at least how many extra dresses would he
need to stitch every day?

i dont get it. where are the "descriptions"?

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

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
