Answer : 
c = 10 radical 2 
Step-by-step explanation:
10^2 + 10^2 = c^2 
100 + 100 = c^2 
200 = c^2 
 
        
             
        
        
        
Answer:
<h2>c=15m+40</h2>
Step-by-step explanation:
Step one:
given data
charged = $40 call fee
additional charges= $15 per mile
let the number of miles be m
and let the total charges be c
Required, the linear function which represents the total charges
Step two:
the equation for the charges in slope-intercept form is 
c=15m+40

Answer:
dy/dx = x=-1
Step-by-step explanation:
by use of intergration to get the values of yaxis and x axis,,the values are -2, -4, 
 
        
             
        
        
        
The ration of boy campers to total campers is 8:15, and the ratio of girl campers to total campers is 7:15.  Using this information, we can answer this question by setting up proportions.
<u>For boys:</u>

<em>*Cross multiply*</em>
15x=1560
<em>*Divide both sides by 15*</em>
x=104
There are 169 boy campers.
<u>For girls:</u>

<em>*Cross multiply*</em>
15x=1365
91=x
There are 91 girl campers.
Hope this helps!!
