The old photocopier can make x manuals in an hour. The new photocopier can make 4x. Combined, they made 5x manuals in an hour.
In one hour they can make 1/28 of the manuals.
1/(28*5)=1/140 is the rate.
The new photocopier can make all the manuals in 4/140 or 35 hours.
The old one can make them in 140 hours.
Answer:
579 degrees
Step-by-step explanation:
579=360+219
so 2 is the remainder of 4
The answer is the first option: I, II and III.
The explanation is shown below:
1. By definition, there is a joint variation when a variable depends on two or more different variables. Therefore, you can express it as following:
Where and are the variables and is the constant of proportionality.
As you can see, is directly proportional to and .
2. Keeping the information above, you have:
I) ( varies jointly with , and .
II) (If is the constant of proportionality, varies jointly with and ).
III) ( varies jointly with and .
