Answer:
30 cm
Step-by-step explanation:
So what we are given here is a case of similar figures.
When we are given similar figures, the ratio of the width of both figures should be similar to the ratio of the length of both figures.
I'll demonstrate it in the following problem.
We know one rectangle has a length of 18 cm and a width of 6cm.
The other rectangle has a width of 10 cm.
Let's take a ratio of the width of both rectangles.
We take the width of 6 cm for the first rectangle to the width of 10 cm for the second rectangle.
w1 = 6 cm
w2 = 10 cm
6 cm : 10 cm = 3 : 5
The ratio given is 3 : 5. Let's use these ratios to find lengths.
l1 = 18 cm
l2 = x cm
3 : 5 = 18 : x
To find x, we just solve this like an equation, where we let ratios be division signs.
3/5 = 18/x
Multiply both sides by 5x
3x = 90
Divide both sides by 3
x = 30 cm
The length of the missing side is 30 cm. We found the answer to the length by using the ratios obtained from the widths.

A coin is Flipped 3 times. What IS the probability that the coin lands heads up once and tails up twice if order does not matter?
Answer:
The probability that the coin lands heads up once and tails up twice is .375, or 3/8.
Step-by-step explanation:
Check the conditions for a binomial distribution problem:
Define success = heads and failure = tails.The number of trials is fixed; n = 3.Each coin flip is independent of the other.Probability p = .5 of getting either heads or tails.We need to use combinations to determine the probability of getting one success (one head) and two failures (two tails).
The combination would be 3 choose 1: [tex]p = {3 \choose 1} (.5)^1(.5)^2[/tex].
There is one success and two failures, denoted by the superscripts above the probability p = .5.
Use a calculator to evaluate and we get:
[tex](3)(.25)(.5) = .375[/tex]The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

URGETN DUE IN 20 MINUTES PLEASE HELP. Tammy went to Outback for dinner, and took Sue with her. The total bill cost $68.72. Service
was good so they left a 22% tip. If they split the bill, what did each of them pay for dinner.
Answer:
Step-by-step explanation:
find the tip
68.72 * 0.22 (22%) = 15.1184
I was hoping that 68.72 + 15.1184 would equal a nice round number, like if it had been 80 total, then they both could have dropped 40 dollars. which would make sense, and is probably what would really happen. But this is math, :D and it really doesn't have to make sense, it just has to be accurate.
so 68.72+15.12 = 83.84
83.84 / 2 =41.92 they each paid 41.92 or for crying out loud, would they really dig around for 92 cents? just give the waiter one whole dollar. So for accuracy they would each pay $41.92, but really they would each pay 42.00 dollars.. and to even be more real. they would each pay $40.00

Multiply 7•2 which is 14, then multiply that by 2 so 14•2 because the sides are symmetrical, and that would be 28. After that you subtract 7-(3+3) to get the length of the center piece, and that would be 1, and multiply that by 3 which is 3. After that you add 28+3 and that's 31
Determine whether the sequence converges or diverges. If it converges, give the limit.
9, 27, 81, 243,
The sequence diverges because the value of the absolute common ratio r is greater than the 1.
What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We have series:
9, 27, 81, 243....
The above series is a geometric progression with common ratio r is 3
[tex]\rm r =\dfrac{27}{9}[/tex]
r = 3
We know the formula for a geometric sequence:
[tex]\rm S_n = 9(3)^n[/tex]
[tex]\rm S_n = 3^{n+2}[/tex]
A geometric series converges only if the absolute value of the common ratio:
r < 1 and
It diverges if the ratio ≥ 1
Here the value of r = 3 which is greater than the 1 so the sequence diverges.
Thus, the sequence diverges because the value of the absolute common ratio r is greater than the 1.
