A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?

Answers

Answer: The number of canned goods in 7th row = 64.

Step-by-step explanation:

The given numbers of canned goods in every row( starting from first ) is represented as

40 , 36, 32, ...

There is a common difference between numbers(d)= 4

∴ Its is an Arithmetic progression.

First term (a) = 40

nth term in A.P. : a(n)= a+(n-1)d

7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64

So, the number of canned goods in 7th row = 64.

Clara played a video game with three levels. It took her 2 hours and 25 minutes to beat the first level and 2 hours and 25 minutes to beat the second level. Clara played the final level for 1 hour and 50 minutes to finish the game. She beat the final level and stopped playing at 5:20 pm . What time did Clara start playing the game

Answers

Answer: 11:40 am

Step-by-step explanation:

Step 1: we are going to add all the hours she played so these are the hours:

1st level: 2hours and 25min

2nd level: 2hours and 25min

3rd level: 1hour and 50min

When we add these this equals 5hours and 40min.

Step 2: Now we are going to subtract the hours so 5:20pm minus 5hours and 40min is 11:40am

Therefore Clara started playing video games at 11:40am
