Stan is serving lemonade at the school dance out of a cylindrical container. The radius is 10 inches and the height is 36 inches. The lemonade is poured into cone shaped cups with a radius of 2 inches and a height of 5 inches. How many full cone shaped cups can be filled from the cylindrical container?

540 cups

Step-by-step explanation:

Number of cone shaped cups = Volume of cylinder/volume of cone

Cylinder:

r = 10 inches

h = 36 inches

Volume = πr²h

           = π * 10*10*36

           = 3600 π cubic inches

Cone:

r = 2 inches

h = 5 inches

Volume = (1/3)πr²h

Number of cones = 3600 π / (20π/3)

                         =  540

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.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
