Ricky and Patrick are scuba diving. Ricky started out 12 feet below the surface. He descended 8 feet, rose 7 feet, and descended 13 more feet. Then he rested. Patrick started out at the surface. He descended 25 feet, rose 8 feet and descended another 6 feet. Then he rested. Which person rested at a greater depth? A Ricky B Patrick C They were at the same depth

A) Ricky

Step-by-step explanation:

Ricky:

-12 - 8 + 7 - 13 = -26

Patrick:

-25 + 8 - 6 = -23

A Ricky

Step-by-step explanation:

Ricky

12 feet below the surface  : -12

Descended 8feet  : -8

Rose 7 ft  : + 7

descended 13 ft  :-13

total = -12 -8+7-13 =-26 ft

Patrick

started at surface :0

descended 25  : -25

rose 8 ft : +8

descended 6ft :-6

total = 0-25+8-6 =-23 ft

Ricky has a lower number so he is at a greater depth   (lower down)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
