Given:
Leela invests 500 at 4.5%
VI = 500 x 1.045^t
Adele invests 500 at 4.5% but 2 years before Leela invested
Vi = 500 x 1.045^2+t
<span>The total value of Adele’s account is approximately what percent of the total value of Leela’s account at any time, t?
</span>
[500 x 1.045^2+t / 500 x 1.045^t] * 100%
1.045² x 100% = 1.092 x 100% = 109.2%
To check: t =1
Adele: 500 x 1.045^2+1 = 500 x 1.045³ = 570.58
Leela: 500 x 1.045^1 = 500 x 1.045 = 522.50
570.58 / 522.50 = 1.092
1.092 x 100% = 109.20%
The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.
In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.
i.e 
= 
Red 6
Green 3
Yellow 3
Total 12
Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.
Thus, n = 12 and r = 3;

= 
= 
= 
= 12 x 11 x 10

= 1320
Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.

Answer:
27.52 percent
Step-by-step explanation:
Percentage increase = (new - original)/ original * 100
new = 318270
old = 249583
Substitute in what we know
percentage increase = (318270-249583)/249583 *100
= (68687/249583) *100
.275207045*100
27.5207045 percent
Answer:
5/8 of a quart.
Step-by-step explanation:
That would be 28/32 - 1/4
= 28/32 - 8 /32
= 20/32
= 5/8 of a quart.
Answer is 8
Work Shown:
f(x) = sqrt(5*x + 4)
f(12) = sqrt(5*12 + 4) ... replace every x with 12
f(12) = sqrt(60 + 4)
f(12) = sqrt( 64 )
f(12) = 8
