Answer:
The value of W is (P-2L)/2.
Step-by-step explanation:
P=2L+2W
-2L
(P-2L)/2=(2W)
(P-2L)/2=w
An event measured in days would be something long enough that to measure it in hours would be too big of a number. For example, the Olympics could be measured in days because it takes place over the course of several weeks, so keeping track of Day 1, Day 2, etc. would make more sense than counting by hours.

40 - 30 = 10
A $10 markdown rate was placed on the trousers.
10/40 = 1/4
That means a 1/4, or 0.25 (25%), markdown rate was placed on the trousers.

Answer:
x = 3.4
Step-by-step explanation:
recall that for a right angle with an internal angle θ,
cos θ = adjacent length / hypotenuse
in our case,
θ = 55 deg
adjacent length = x units
hypotenuse = 6 units
substitute these into the formula above
cos θ = adjacent length / hypotenuse
cos 55 = x / 6 (multiply both sides by 6)
x = 6 cos 55 (use calculator)
x = 3.4415
x = 3.4 (rounded to nearest tenth)
