Answer:
1). 250 - 60t
2). 60t
Step-by-step explanation:
"Camila started her collection with 250 cards and decreased by 60 cards each year"
Starting number of cards with Camila = 250
Decrease in number of cards each year = 60
Decrease in number of cards after 't' years = 60t
Number of cards after 't' years = 250 - 60t
"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."
Number of cards with Camila = 0
Number of cards grew each year = 60
Number of cards after 't' years = 60t + 0 = 60t
Answer:
There is a period of 3 consecutive days in which the website was hits at least 60 times.
Step-by-step explanation:
A web site was hit 300 times over a period of 15 days.
To solve this question we will use the Pigeonhole Principle.
Here, n = 300 and k = 5
We will find 
to get that there is a hole with at least 
pigeons.
Hence, there is a period of 3 consecutive days in which the website was hits at least 60 times.
Answer: 416 boxes
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each box and the volume of the storage space.
Since both are rectangular prisms:
Volume = length x width x height
Box of t -shirts = 20 x 16 x 12 = 3,840 cubic feet
Storage = 200 x 200 x 40 = 1,600,000 cubic feet
Next, we have to divide the storage's volume by the volume of each box:
1,600,000 / 3,840 = 416.6 =416 boxes
Feel free to ask for more if needed or if you did not understand something.
