At a ballroom dancing lesson there were twenty-three students. Deena danced with six boys, Chloe with seven, Moira with eight and so on for all the girls up to the last girl, Anna, who danced with all the boys. How many boys were at the lesson?
Answers
First girl, Deena danced with 6 boys.
Second girl, Chloe danced with 7 boys.
Third girl, Moira danced with 8 boys.
And so last girl, Anna danced with all boys, given is an arithmetic series as 6, 7, 8, ........, a+(n-1)d.
Let's assume number of girls are 'n'.
Last term of a.p. series would be number of boys = a+(n-1)d.
Here a=6 and d=1, so number of boys = 6+(n-1)*1 = 5+n.
Given there were 23 students.
So total students = number of girls + number of boys
23 = n + (5+n)
23 = 2n + 5
2n = 23-5 = 18
n = 9.
Hence, there were 9 girls and 14 boys.
Out of 28 students in a class, 7 have blue eyes. What is the probability a student picked at random from the class does NOT have blue eyes?
A) 1/4
B) 3/4
C) 1/7
D) 6/7
Answers
[tex] \frac{7}{28} = \frac{1}{4} [/tex]
so the probability of pi king someone without blue eyes is the entire sample minus the probability of blue eyes so
[tex]1 - \frac{1}{4} = \frac{4}{4} - \frac{1}{4} = \frac{3}{4} [/tex]
so there is 75% chance of picking someone without blue eyes.

4. Rosa plays games at a fair. She can buy 8 game tokens for $ 1. Each game cost 2 tokens. How many games can she play with 120 tokens? Write a rule and complete the table.
Please help with the bottom one too
Answers
Answer:
60 tokens and the rule is the number of tokens divided by 2
20 cups of oats and the number of cups of raisins times 2
Rosa can play a total of 60 games with 120 tokens.
Explanation:To determine the number of games Rosa can play with 120 tokens, we need to divide the total number of tokens by the number of tokens required to play a game. Since each game costs 2 tokens, we divide 120 by 2. This gives us the number of games Rosa can play, which is 60.
We can also write a rule to calculate the number of games Rosa can play. Let G represent the number of games, and T represent the number of tokens. The rule would be: G = T ÷ 2. We can substitute T with 120 to find G: G = 120 ÷ 2 = 60.
Here is a table that shows the number of games Rosa can play for different numbers of tokens:

Answers
Answer:
Saras Mean on her reading test is 78
Lee's Mean on his reading test is 79
Step-by-step explanation:
You add grades for Sara's test together and then you will divide by the= number of graded test there were and you will get 78.
You add Lee's Grades for the test together and divide by the number of graded test there were and you will get 79.
The mean of Sara's reading test scores is 78, and the mean of Lee's reading test scores is 79.
To find the mean (average) score of Sara's and Lee's reading tests, we need to add up all of the scores and then divide by the number of scores.
Let's start with Sara's scores:
Sara's scores: 98, 100, 65, 78, 98, 46, 100, 100, 45, and 50.
Add up Sara's scores:98 + 100 + 65 + 78 + 98 + 46 + 100 + 100 + 45 + 50 = 780
Divide the total by the number of scores (which is 10):Mean of Sara’s scores = 780/10 =78
Now, let's calculate the mean for Lee's scores:
Lee's scores: 97, 67, 89, 99, 100, 45, 79, 89, 58, and 67.
Add up Lee's scores:97 + 67 + 89 + 99 + 100 + 45 + 79 + 89 + 58 + 67 = 790
Divide the total by the number of scores (which is 10):Mean of Lee’s scores = 790/10 = 79
So, the mean of Sara's reading test scores is 78, and the mean of Lee's reading test scores is 79.

C- n =5/3
D- n=5/2
Answers
4/5=.8
1/5=.2
The answer is n=-1
Answer:
B. n = 2
Step-by-step explanation:
Given equation,
[tex]\frac{3}{5}n-\frac{4}{5}=\frac{1}{5}n[/tex]
[tex]\frac{3n-4}{5}=\frac{n}{5}[/tex]
[tex]3n-4=n[/tex]
Subtracting n on both sides,
[tex]3n - 4 - n = n - n[/tex]
[tex]2n - 4 = 0[/tex]
Adding 4 on both sides,
[tex]2n=4[/tex]
Divide both sides by 2,

In 2000, the circulation of a local newspaper was 3,250. In 2001, its circulation was 3,640. In 2002, the circulation was 4,100. a. Find the percent of increase in the newspaper’s circulation from 2000 to 2001 and from 2001 to 2002. b. Which period had a higher percent of increase, 2000 to 2001, or 2001 to 2002?
Answers
The formula for percentage change is:
(New number - Original number) / Original number × 100 = Percentage change
(3640-3250)/3250 x 100 =
(390)/3250 x 100 =
.12 x 100 = 12%
(4100-3640)/3640 x 100 =
(460)/3640 x 100 =
.1263736264 x 100 = ~ 12.6%
2001 to 2002 had a higher percent of increase.
The percent of increase in the newspaper’s circulation from 2000 to 2001 and from 2001 to 2002 is 12% and 12.6% respectively
Given:
2000 = 3,250
2001 = 3,640
2002 = 4,100
Percentage change2000 to 2001 = (Difference in change) / old value × 100
= (3,640 - 3,250) / 3,250 × 100
= 390 / 3,250 × 100
= 0.12 × 100
= 12%
Percentage change 2001 to 2002 = (Difference in change) / old value × 100
= (4,100 - 3,640) / 3,640 × 100
= 460 / 3,640 × 100
= 0.126373626373626 × 100
= 12.63736263736263%
Approximately,
12.6%
Therefore, the period which had a higher percent of increase is 2001 to 2002

How many inches are equal to 10 centimeters? Remember, 2.54 cm = 1 in. Round your answer to the nearest hundredth. Do not include units in your answer.
Answers
Answer:
10 centimeters = 3.94 .Step-by-step explanation:
We are given 2.54 cm = 1 in.
We need to convert 10 centimeters into inches.
We have 2.54 cm = 1 in.
On dividing both sides by 2.54, we get
[tex]\frac{2.54}{2.54}cm = \frac{1}{2.54} in[/tex]
1cm=[tex]\frac{1}{2.54}[/tex] in.
In order to find the number of inches in 10 centimeters, we need to multiply [tex]\frac{1}{2.54}[/tex] by 10.
On multiplying [tex]\frac{1}{2.54}[/tex] by 10, we get
=[tex]10\times \frac{1}{2.54}[/tex]=3.94.
Therefore,
10 centimeters = 3.94.10 centimeters is approximately equal to 3.94 inches when converted using the conversion factor of 1 inch equals 2.54 centimeters.
The student is asking for conversion of a length measurement from centimeters to inches. Given that 1 inch equals 2.54 centimeters, you can convert 10 centimeters to inches by dividing by the conversion factor. Here's the calculation:
Identify the conversion factor: 2.54 centimeters per inch.
Divide the number of centimeters by the conversion factor: 10 cm \/ 2.54 cm/in = approximately 3.94 inches.
Therefore, 10 centimeters is approximately equal to 3.94 inches when rounded to the nearest hundredth.

The running back for the Bulldogs football team carried the ball 3 times for a total loss of 6 3/4 yards. Find the average change in field position on each run. Enter the average change as a simplified mixed number.
Answers
Average of -2 1/4 yards per play
The average change in field position per run is -2 1/4 yards. This is found by dividing the total yardage lost (6 3/4 yards) by the number of runs (3).
Explanation:The subject of this problem is calculating the average. In this case, we are looking for the average yardage lost by the running back on each run. The running back for the Bulldogs football team has carried the ball 3 times for a total loss of 6 3/4 yards.
To find the average change in field position on each run, divide the total loss by the number of runs:
Convert the mixed number 6 3/4 to an improper fraction. This gives us 27/4. Divide the numerator (27) by the denominator (4). This gives us -6.75. Divide -6.75 by 3 (the number of runs). This gives us -2.25. Convert -2.25 to a mixed number, which gives us -2 1/4.
Therefore, -2 1/4 yards is the average change in field position on each run.

A person needs to pay TK. 500 to by pencils and TK. X for any additinal unit of pencil.If the cumstomer pays a total of TK. 4700 for 1200 pencils what is the value of X?
Answers
Answer:
3.50
Step-by-step explanation:
First we take the 500 fee for purchasing pencils off of the total:
4700-500 = 4200
This means we pay 4200 for 1200 pencils; dividing this will tell us the amount per pencil, x:
4200/1200 = 42/12 = 21/6 = 7/2 = 3.5
Thus we pay 3.50 per pencil.
The value of X for any additional pencil is gotten as;
X = 3.5
We are told that base amount for pencils is TK. 500 and amount per pencil is TK. X.
This means formula for total cost for n number of pencils is;
C(n) = 500 + Xn
We are told that a customer pays TK. 4700 for 1200 pencils. Thus;
C(n) = TK. 4700
n = 1200 pencils
Therefore;
4700 = 500 + 1200X
1200X = 4700 - 500
1200X = 4200
X = 4200/1200
X = TK. 3.5 per pencil

What is the difference in the sum of the exterior angles measures of a rectangular nonagon and a rectangular dodecagon?
Answers
The sum of the exterior angles of any polygon is 360 degrees, thus the difference between the sums of the exterior angles of a nonagon and a dodecagon is 0 degrees.
The question asks about the difference in the sum of the exterior angle measures of a nonagon and a dodecagon. The key concept here is that for any polygon, the sum of the exterior angles is always 360 degrees, regardless of the number of sides.
Therefore, the sum of the exterior angles of both a nonagon (9-sided polygon) and a dodecagon (12-sided polygon) would be 360 degrees each. Consequently, the difference in their sums would be 0 degrees.
