A worker places tape around a rectangular shipping label that is 2 times longer than it is wide. How much tape does the worker n
valina [46]

Answer:

444 :) (angel number, haha)

Step-by-step explanation:

it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74

so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!

Answer:

C) 2400

Step-by-step explanation:

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

Computers = 10

Printers = 3

Scanners = 5

Telephone = 8

Copiers = 2

Possible outcome = 10 x 3 x 5 x 8 x 2 = 2400
