An up-and-coming artist has 85 followers on Twitter and this number doubles every week. In what week will the artist first reach 1,000 followers? Use at least two different methods to come up with your answer.
Answers
It will take week to reach
followers.
First, we are using two step to find the answers.
- Division
- Addition
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,
- Second week has
followers.
- Third week has
followers.
- Fourth week has
followers.
- Fifth week has
followers.
- Sixth week has
followers.
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.

Bowl of Curry = C
1 Hour = H
----------------
A restaurant requires 4 + 1/2 ounces of butter for every bowl of curry it makes...
C = 9/2 * B
In an hour, an average of 2 + 1/2 bowls of curry is served...
H = 5/2 * C
... Which means that: H = 5/2 * 9/2 * B
... So: H = 45/4 * B
The question was: How many ounces of butter are required in 1 + 1/2 hours?
Here is the answer:
3/2 * H = 3/2 * 45/4 * B
3/2 * H = 135/8 * B
In words, 16 + 7/8 ounces of butter would be required over a period of 1 + 1/2 hours.

The length of segment AB is 6.71 units
How to determine the length?
The given parameters are:
A = (0,0) and B = (6,3)
The length AB is calculated using:
Substitute known values
Evaluate the sum of exponents
Evaluate the square root
AB = 6.71
Hence, the length of AB is 6.71 units

#SPJ2
dist(A,B)=√[(x₂-x₁)²+(y₂-y₁)²].
We have these points: A(0,0) and B(6,3); its distance will be:
dist(A,B)=√[(6-0)²+(3-0)²]
=√(6²+3²)
=√(36+9)
=√45 ≈ 6.71
Answer: D. 6.71 units.

y=the tens digit.
The number is: 10y + x
The reversed number is: 10x+y
The units digit is twice the tens digit, then: x=2y
a)we suggest this system of equations:
x=2y
2(10y+x)=12+(10x+y)
We can solve this system of equations by substitution method:
2(10y+2y)=12+[10(2y)+y]
2(12y)=12+21y
24y=12+21y
24y-21y=12
3y=12
y=12/3
y=4
x=2y
x=2(4)=8
The number is: 10y+x=10*4+8=48
Answer: the number is 48.
b)
the number is: 10x+y
we can suggest this system of equations:
8(x+y)=(10x+y)+19
x=y-2
We can solve this system of equations by substitution method.
8(y-2+y)=[10(y-2)+y]+19
8(2y-2)=11y-20+19
16y-16=11y-1
16y-11y=-1+16
5y=15
y=15/5
y=3
x=y-2
x=3-2=1
The number is: 10x+y=10*1+3=13
Answer:the number is 13.
c)
The number is: 10x+y
The number reversed is: 10y+x
we can suggest this system of equations:
y=2x
2(10x+y)=9+(10y+x)
We solve this system of equations by substitution method:
2(10x+2x)=9+[10(2x)+x]
2(12x)=9+21x
24x=9+21x
24x-21x=9
3x=9
x=9/3
x=3
y=2x
y=2*3=6
The number is: 10x+y=10*3+6=36
Answer: the number is 36
