Answer:
A. 200 packages
Step-by-step explanation:
The number of packages per roll can be found by dividing the length of a roll by the length of tape needed for each package.
__
For each package:
(2.375 in/piece)×(4 piece/package) = 9.5 in/package
Per roll:
(1900 in/roll) / (9.5 in/package) = (1900/9.5) packages/roll
= 200 packages/roll
The machine can seal 200 packages with a roll of tape 1900 inches long.
The volume of a cube is s^3
divide x^3 = 185 = 5.69 cm
Okay, so let's make a sample space where in one section, one toy is the leader of each group for as many possibilities as there are.
T K E
T E K
K E T
K T E
E T K
E K T
There are 6 possibilities, and so each arrangement has a 1 over 6 chance of being used.
