Hello!
3 inches equals 90 miles
We have to find what multiplied by 3 is 1/2
we can do 3 / 1/2 to find this
3 / 0.5 = 6
So they divide it by 6
We do 90/6
90/6 = 15
The answer is 15
Hope this helps!

2 2/3 + 1 3/5
= 2 10/15 + 1 9/15
= 3 19/15
= 4 4/15
answer is 4 4/15 (4 and 4/15)
        
             
        
        
        
Answer:
volume of the solid is 3.180
Step-by-step explanation:
given data
line x + y = 2
parabola  x2 + y = 4
to find out 
the volume of the solid
solution
we draw a graph between line and parabola as show in fig given below attach
line cut at (-1,3) and (2,0)
so the length of diameter is ( 4 - x²) - (2 - x) 
and radius of this semi circle will be ( 4 - x² - 2 + x ) /2 
radius = (-x² + x + 2 ) /2 
and r(x) will be  =  (-x² + x + 2 ) /2 
and A(x) will be  = π ( r(x)² ) /2
we will integrate from -1 to 2 
=  
 
=  
 
= 81π / 20
volume of the solid is 3.180
