The lengths of the three sides of a triangle (in centimeters) are consecutive odd
integers. If the perimeter is 45 centimeters, find the value of the shortest of the three
side lengths.

Answers

Answer 1

Answer:

13, 15,17

Step-by-step explanation:

Let x = the first number

Let x + 2 = the second number

Let x + 4 = the third number

Consecutive means in order like 1,2,3 or 20,21,22. Consecutive odd means that you want three numbers in order that are odd.  Each number would be 2 more than the number before.  For example 5 + 2 = 7.  We would have to add 4 to 5 to find the next consecutive odd number.

x + (x + 2) + (x +4)  = 45  I put the numbers in parentheses so you could see the first number plus the second number plus the third number equals 45

x + x+ 2 + x+ 4 = 45  Combine like terms

3x + 6 = 45  Subtract 6 from both sides of the equation.

3x = 39  Divide both sides by 3

x = 13

Add 2 to that to get the next odd number.

Add 4 to 13 to get the third odd number.

Answer 2

Answer: 13 cm

Step-by-step explanation:

Let the value of the shortest of the three side lengths is x.

Since the three sides of a triangle are consecutive odd

integers, hence: x, x+2, x+4.

Thus,

[tex]P=x+(x+2)+(x+4)\\45=x+x+2+x+4\\45=3x+6\\45-6=3x+6-6\\39=3x\\[/tex]

Divide both parts of the equation by 3:

[tex]13\ cm=x[/tex]

A ticket to see Pink in concert costs $113.50 $ ⁢ 113.50 at regular price. An online ticket company is offering tickets at a 10% 10 % discount. Your friend bought a ticket at the discounted price but found out he can't go. He's offering the ticket to you at an additional 25% 25 % off what he paid. What price could you get the concert ticket for if you bought it from your friend? Round your answer to the nearest cent, if necessary.

Answers

Your friend bought the ticket at the discounted price which would be 10% of 113.50. 10% times 113.50 equals $11.35. 113.50-11.35=102.15. He is giving u an additional 25% off that. That means 25% times 102.15. That equals 25.5375. You get that discount off 102.15 so ur ticket would cost 76.6125, rounded would be 76.61

Answers

300 teenagers went to the zoo.

How to find the how many teenagers went to the zoo?

given that

Tickets to the zoo cost $4 for children.

Tickets to the zoo cost $5 for teenagers.

Tickets to the zoo cost $6 for adults.

1200 people come to the zoo every day.

on a certian day, the total revenue at the zoo was $5300.

Let the number of adults be x.

The number of teenagers be y.

and the number of children that went to the zoo 8y/3.

Consider the question

1200 people come to the zoo every day.

x + y + 8y/3 = 1200

now, take L.C.M between y and 8y/3

[tex]x + \frac{(3y + 8y)}{3} = 1200 \\ x + \frac{11y}{3} = 1200[/tex]

now multiply with 3 to this equation.

3x + 11y = 3600 .......................(1)

tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults.

according to the question

6x + 5y + 32y/3 = 5300

Now take the L.C.M between 5y and 32y/3

6x + 47y/3 = 5300

now multiply with 3 to this equation.

18x + 47y = 15900 ...................(2)

now, multiply equation (1) with 6

18x + 66y = 21600 .....................(3)

now, subtract equation (1) in equation (2)

(18x - 18x) + (66y - 47y) = (21600 - 15900)

19y = 5700

y = 5700/19

y = 300

Hence, the 300 teenagers went to the zoo.

c. Write an explicit formula for the sequence.

Answers

The recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19 and the explicit formula for the sequence is Tn = 22 - 3n

a. Is the sequence arithmetic, geometric, or neither

On the given graph, we have the following points

19, 16, 13, 10, 7

These points represent the nth term of the sequence

See that the points have a common difference of -3

Hence, the sequence is an arithmetic sequence

b. Write a recursive formula for the sequence.

In (a), we have

T1 = 19

d = -3

So, we have

T2 = T1 + d

This gives

T2 = T1 - 3

Express 2 as 1 + 1

So, we have

T(1+1) = T1 - 3

Express 1 as n

So, we have

T(n+1) = Tn - 3

Hence, the recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19

c. Write an explicit formula for the sequence.

In (a), we have

T1 = 19

d = -3

So, we have

Tn = T1 + (n - 1)d

This gives

Tn = 19 + (n - 1) * -3

Evaluate

Tn = 19 + 3 - 3n

Evaluate the sum

Tn = 22 - 3n

Hence, the explicit formula for the sequence is Tn = 22 - 3n

Answers

The probability that it is gold is (1/3).

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. If two events are mutually exclusive, then there is a 0 percent chance that they will both happen at the exact moment. Two events are said to be mutually exclusive if they share no elements (their intersection is the empty set). Consequently, P(A∩B)=0.

Let A be the event that a gold marble is picked.

Let B₁ and B₂ be the event that the first bag is chosen and the second bag is chosen respectively.

Given: P (B₁ ) = 2.P(B₂)

Also, P(B₁) + P(B₂) = 1

∴ 2P(B₂) + P(B₂) =1

3P(B₂) = 1

P(B₂) = 1/3 and  P(B₁) = 2/3

Now

P(A)

= P(A∩(B₁∪B₂))

= P[(A∩B₁)∪(A∩B₂)]

Probability adds up because the events are mutually exclusive

= P(A∩B₁) + P(A∩B₂)

= P(B₁). P(A/B₁) + P(B₂). P(A/B₂)

= (2/3)×(3/16) + (1/3)×(15/24)

have on the mean and median?
0, 40, 60, 70, 75, 80, 85, 95, 95, 100

Answers

We can conclude that the value of both mean and median increases when we remove the lowest value, 0, from the data set.

What do we mean by mean and median?The mean is the average of a set of values in mathematics and statistics. The mean can be calculated in a variety of ways, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean.The median is the number in the middle of a sorted list of numbers, and it is more descriptive of the data set than the average. When there are outliers in the sequence that could skew the average of the values, the median is sometimes used instead of the mean.

(1) First, we have to find the value of the mean and median with the value of 0.

(A) Mean: Sum of all values/Number of terms

= 700/10= 70

(B) Median: If the number is an even number, add the two middles and divide by 2.

= 75 + 80/2= 155/2= 77.5

(2) Now, we have to find the value of the mean and median without the value of 0.

(A) Mean: Sum of all values/Number of terms

= 700/9= 77.77

(B) Median: If there are an odd number of observations, the number in the middle of the list is the median.

= 5th term from both sides is the middle value= 80

Therefore, we can say that the value of both mean and median increases when we remove the lowest value, 0, from the data set.
