Answer:
The soda costs 2.20 and the sandwich costs 7.70
Step-by-step explanation:
To find this, set the soda cost as x. We now know that the sandwich cost is 3.5x. Add these together and set equal to 9.90
x + 3.5x = 9.90
4.5x = 9.90
x = 2.20
This is the cost of the soda. Now we can multiply that by 3.5 to get the sandwich cost. 
3.5 * 2.20 = 7.70
 
        
             
        
        
        
The velocity v and maximum height h of the water being pumped into the air are related by the equation 
v= 
where g = 32
(a) To find the equation that will give the maximum height of the water , solve the equation for h
v= 
Take square root on both sides
 = 2gh
 = 2gh
Divide by 2g on both sides
 = h
 = h
So maximum height of the water h = 
(b) Maximum height h= 80
velocity v= 75 ft/sec
 Given g = 32
h = 
h = 
h= 87.89 ft
The pump withe the velocity of 75 ft/sec reaches the maximum height of 87.89 feet. 87.86 is greater than the maximum height 80 feet.
So the pump will meet the fire department needs.
