Step-by-step explanation:
It will take week to reach followers.
First, we are using two step to find the answers.
Division:
By given, A artist has followers.
Every week the no. of. followers is doubled .
Now, find how many week the artist reach followers.
Since week followers is doubled,
So ,
Thus,
Which is not possible .
Then, it take week to reach the followers.
Addition:
By given, A artist has followers.
Every week the no. of. followers is doubled .
To find how many week the artist reach followers.
Now, the first week has followers.
followers doubled.
followers doubled in every week .
Then,
Hence, the artist reach followers in mid week of to week .
so, it approximately take week to reach followers but which is impossible to take decimal in week .
Thus, the artist take week to reach the followers.

Answer:
5.8 , which approximately is 6 weeks.
Step-by-step explanation:
the first method is the short one since u just have to double the 85 then divide to 1000.
1000 ÷ ( 85 × 2)
1000 ÷ 170 = 5.882,,,,,. round off to whole number to get 6.
the second method is the addition method.
we start by 85 then keep doubling 85 for every week........inshort.......we add 170 to each weeks number to get the number of followers for the following week.
85 ⇒ 170 ⇒ 340 ⇒ 510 ⇒ 680 ⇒ 850 ⇒ 1020.
1st 2nd 3rd 4th 5th 6th week.
u notice that we add (85×2), 170, to get the following week's number of followers..
in 5 weeks..... the number of followers is yet to get to 1000.
when u divide, u get 5.8.....,and it is not logic to say 5.8823....weeks
since she reaches 1000 followers in the 6th week.......though there is an addition,,,, it is the most appropriate answer.
Answer:
number of songs = 9 songs
Step-by-step explanation:
According to Marcus the the song are each 3 start fraction , 1 divided by 2 end fraction minutes long. This can be expressed mathematically as 3 1/2 minutes long.
The slide show is 31, start fraction , 1 divided by, 2 end fraction minutes. This can be expressed also as 31 1/2 minutes long. The slide show contains the entire song.
Recall each song is 3 1/2 minutes long . The whole number fraction can be converted to improper fraction as 7/2 minutes long.
The whole slides show can be converted to improper fractions as 63/2 minutes long.
The number of song in the slideshow can be solved when we divide the total time in the slideshow by the time of each song.
number of songs = 63/2 ÷ 7/2
number of songs = 63/2 × 2/7
number of songs = 63/7
number of songs = 9 songs
