Answer:
She uses 243 beads for the 5th string.
Step-by-step explanation:
In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:
The second uses 9, 3 * 3 = 9
The third uses 27, 9 * 3 = 27
The fourth uses 81, 27 * 3 = 81
And the 5th uses 243, 81 * 3 = 243.

A’s increase is 1.8/1.5=6/5; B’s increase is 1/0.6=5/3.
A formula for A is A(t)=1.5(6/5)^t and for B, B(t)=0.6(5/3)^t where t is years since 2004.
When A=B, 1.5(6/5)^t=0.6(5/3)^t.
Taking logs: log1.5+tlog(6/5)=log0.6+tlog(5/3), t(log(5/3)-log(6/5))=log1.5-log0.6.
tlog(25/18)=log2.5, t=log2.5/log(25/18)=2.7893 approx.
This occurs during 2006 around mid-October.
Common sales=1.5(6/5)^2.7893=0.6(5/3)^2.7893=$2.4943 billion.
Answer:
(a) Bar chart
Explanation:
A bar graph or a bar chart is a graphical representation of data and it belongs to the frequency graphs. It is the best way to illustrate the frequencies of political preference because it is very easy to interpret and it shows the relative sizes that are we can see which political preference is the most common and which is the least, at one glance.
Therefore, we can say that
The best way to illustrate the frequencies for each political preference is a bar graph.
Hence, the option (a) is correct.
Answer:
1) I think the answer is A
2) (A), (D) (B) Those numbers are irrational because irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios of integers. (change some words please)
3) This number is irrational because irrational numbers are all the real numbers that are not rational.
4) 6/25
5) 0.875 since I can't show work, you divide 7 by 8
6) I don't know the answer, so maybe D and B ?
7) point A
8) 8.3 inches
9) I think it is the = I am not sure
10) Irrational because it has no pattern

I really hope this helps and good luck. I tried my Best!
