Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.
You just divide V from PV to get P and what you do on one side you do to the other so you get
P = (nRT)/V

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a
Simplify
3/4 = a
In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.
100 cm = 1 m
3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x
300/4 = x
75 = x
Each segment of rope is 75 cm long.
Answer:
80°
Step-by-step explanation:
sides of angle =180°
y= 180-(45+55) = 80°
x=y because x is vertically opposite to y
therefore x =80°
