Joey is putting all of his trophies onto 7 shelves. if he places 6 trophies on each shelf but still has 2 trophies left over , how many trophies does he have ?

44 trophies

Step-by-step explanation:

Since Joey is placing 6trophies in each shelf and there are 7shelves, the total amount of trophies in the 7shelves will be the product of the number of trophies per shelf and the total number of shelf.

This will become;

Total number of trophies in the shelves = 6×7

= 42 trophies

If there are 2 trophies leftover, the total number of trophies Joey has will be 42+2 = 44trophies

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
