Lets say... 7 divided by 21. ok? So... Just take 7, (usually the smaller number, but not in all cases.) and then multiply it by 1. 2. 3. So lets see. 7x1=7 so thats not it. 7x2 is 14 so thats not it. And you want to keep doing that until you get the other number. 7x3 is 21!!! That is the correct number so if you were doing long division like this
   ___3______  <--- the answer would be there.
7|21

Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, her
storchak [24]
Each colection day: D
Number of tops collected on that day: N

D1=1; N1=2
D2=3; N2=8

1) Linear model
N-N1=m(D-D1)

m=(N2-N1)/(D2-D1)
m=(8-2)/(3-1)
m=(6)/(2)
m=3

N-N1=m(D-D1)
N-2=3(D-1)
N-2=3D-3
N-2+2=3D-3+2
N=3D-1

when D=6:
N=3(6)-1
N=18-1
N=17

<span>What is the number of tops collected on the sixth day based on the linear model?
</span>The number of tops collected on the sixth day based on the linear model is 17.

2) Exponential model
N=a(b)^D
D=D1=1→N=N1=2→2=a(b)^1→2=ab→ab=2   (1)

D=D2=3→N=N2=8→8=a(b)^3→8=a(b)^(1+2)
8=a(b)^1(b)^2→8=ab(b)^2   (2)

Replacing (1) in (2)
(2) 8=2(b)^2
Solving for b:
8/2=2(b)^2/2
4=(b)^2
sqrt(4)=sqrt( b)^2 )
2=b
b=2

Replacing b=2 in (1)
(1) ab=2
a(2)=2
Solving for a:
a(2)/2=2/2
a=1

Then, the exponential model is N=1(2)^D
N=(2)^D

When D=6:
N=(2)^6
N=64

<span>What is the number of tops collected on the sixth day based on the exponential model?
</span><span>The number of tops collected on the sixth day based on the exponential model is 64</span>

If there are 10 candles and 7 are lit what is the decimal that represents the candles
Kay [80]
If 7 out of 10 candles are lit, then seven-tenths of the candles are lit. The tenths place is directly to the right of the decimal. Since you have seven-tenths, the tenths place will be seven. So, the decimal that represents the candles lit will be 0.7
