Any irrational number produces an irrational number when added to 3/4.
This is because 3/4 is rational (it can be represented as a ratio of two integers). You can get an irrational number only when you add rational to irrational (because rational to rational produces a rational sum).

The company picnic cost $ 1300 for 80 employees
<em><u>Solution:</u></em>
Given that cost of a company picnic varies directly as the number of employees attending the picnic
Let "c" be the company picnic cost
Let "n" be the number of employees attending the picnic
Therefore,


Where "k" is the constant of proportionality
c = kn ---------- eqn 1
<em><u>Given that company picnic costs $487.50 for 30 employees</u></em>
Therefore substitute c = 487.50 and n = 30

<em><u>How much does a company picnic cost for 80 employees?</u></em>
Substitute n = 80 and k = 16.25 in eqn 1

Thus $ 1300 is the cost for 80 employees
 
        
             
        
        
        
Answer:
Mabel used 12 dimes and 7 quarters to pay for her granola bar.
Step-by-step explanation:
A dime= 10 A quarter= 25
12×10=120
7×25=175
175+120=295
12-7=5
 
        
             
        
        
        
The total space in the parking lot is 1600 cars
It is mentioned that  parts of this parking is filled
 parts of this parking is filled
Now we are required to find what is the three-fourths part of 1600
To find it we multiply  times 1600
 times 1600

= 
=
= 1200 cars
Hence 1200 cars fills the three-fourths of the car parking lot that has a capacity of 1600 cars
