Mario's father is building a skateboard ramp in the shape of a triangular prism. Mario has agreed to paint the ramp once its finished if a quart of paint covers 85 ft how many quarts of paint will mario need to buy

6

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.

We need to find the total surface area of the building a skateboard ramp  without its bottom.

So the total surface area is: 262.5 + 168 +73.5 = 504

Hence, the number quarts of paint will mario needs to buy is:

504/85 ≈ 6

Hope it will find you well

answer: howdy

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
