Answer:

Step-by-step explanation:
First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.
The area of the triangle is given by the  formula:

where b is the base:  and h is the height:
 and h is the height: 
thus, in this case we have: 

And now, the volume will be the area of the triangle multiplied by the length  of the prism:
 of the prism:

Substituting the known values: 

The volume in cubic centimeters is 150.
 
        
             
        
        
        
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the total cost of hiring for x hours. Hence:
- Using the points (0, 125) and (15, 950)

The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour

If I did my math correct it should be 47. If you take 284x386 you get 109,624 (that should be the area in square feet) then take 109,624 and divide it into 2346 and you get 46.7280477408. In order to cover it you should round up to 47 bags.
