Assuming the envelope consumption is proportional to the number of typists, you have ...
(12 dz)/36 = x/125
125*(12 dz)/36 = x = 41 2/3
An office of 125 typists would use 41 2/3 dozen envelopes per day.
Answer:
A. f(x)=9x+4
Step-by-step explanation:
Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;
if x=5,then f(5)=9*5+4=45+4=49
Answer:
2.8
Step-by-step explanation:
using cosine rule
= 
s = 
= 2.842 = 2.8
Tan80=5.67
2tan70+tan10=5.67
So tan80=2tan70+tan10
