Answer:
(6 + 9 + 24)/3
Step-by-step explanation:
First, you must add 6, 9, and 24.
6 + 9 + 24
Now you need to divide that sum by 3.
You must use parentheses to show the sum being divided by 3.
(6 + 9 + 24)/3
None of your expressions contain a division sign, so there is no answer contained in the choices. Did you use the equal sign to mean a division sign?

Step-by-step explanation:
At a recent audition school play, 1 out of 3 students who auditioned were asked to come to a second audition . After the second audition ,75% of those asked to the second audition were offered parts. If 18 students were offered parts , how many students were offered to the first audition
Answer:
The total students appearing in first audition = 72
Step-by-step explanation:
As given in the question:
1 out of 3 students were asked to come for second audition.
Let us assume the TOTAL STUDENT who came to first audition = m
So, [tex](\frac{1}{3}) m[/tex] appeared for the SECOND ROUND.
Now, 75% of students appearing in second audition were offered parts.
Calculating 75% of [tex](\frac{1}{3}) m[/tex]
[tex]\frac{75}{100} \times\frac{1}{3} m = 0.25 m[/tex]
Also, as said 18 students were offered parts.
⇒ 0. 25 m = 18
Now, solving for m, we get:
m = 18/0.25 = 72
or, m = 72
Hence, the total students appearing in first audition = 72
Final Answer:
- 24 students were asked to attend the second audition.
- 72 students auditioned initially for the first audition.
Explanation:
Let's tackle the problem step by step.
1. **Find the number of students asked to the second audition.**
We know that 18 students were eventually offered parts after the second audition. We're also given that 75% of those who were asked to the second audition were offered parts. To find out how many students were asked to the second audition, we can set up the following equation:
[tex]\[ \text{Number of students offered parts} =[/tex] [tex]\text{Percentage offered parts} \times \text{Number of students at the second audition} \][/tex]
From the given information:
[tex]\[ 18 = 0.75 \times \text{Number of students at the second audition} \][/tex]
Solving for the number of students at the second audition gives us:
[tex]\[ \text{Number of students at the second audition} = \frac{18}{0.75} = 24 \][/tex]
So 24 students were asked to the second audition.
2. **Find the total number of students who auditioned initially.**
If 1 out of 3 students who auditioned were asked to the second audition, we can infer that the ratio of students asked to the second audition to the total number of students who auditioned is 1:3.
Let's let X represent the number of students who auditioned initially. According to the ratio, we can write:
[tex]\[ \frac{1}{3} \times X = \text{Number of students at the second audition} \][/tex]
We've already solved for the number of students at the second audition, which is 24. Thus:
[tex]\[ \frac{1}{3} \times X = 24 \][/tex]
Solving for X, we get:
[tex]\[ X = 24 \times 3 = 72 \][/tex]
So 72 students auditioned initially for the first audition.
To summarize:
- 24 students were asked to attend the second audition.
- 72 students auditioned initially for the first audition.
In one day a movie theater collected $4275 from 675 people. The price of admission is $7 for an adult and $5 for a child. How many adults and how many children were admitted to the movie theater that day?
To find the number of adults and children admitted to the movie theater, we set up two equations based on the admission costs and total number of attendees. Solving these equations revealed that there were 450 adults and 225 children.
Explanation:The question involves a system of equations where we are required to determine the number of adults and children who were admitted to the movie theater given the total revenue and total number of attendees.
Let's denote the number of adults by A and the number of children by C. Given the price of admission is $7 for an adult and $5 for a child, we can represent the total revenue with the equation:
7A + 5C = 4275
Also, considering the total number of people is 675, we have another equation:
A + C = 675
To solve these equations, we'll use the substitution or elimination method:
From the second equation, express C in terms of A:Therefore, there were 450 adults and 225 children admitted to the movie theater that day.

JL has coordinates J(-6, 1) and L(-4,3).
Find the coordinates of the midpoint.
Answer:
The coordinates of the mid-point of JL are (-5 , 2)
Step-by-step explanation:
If point (x , y) is the mid-point of a segment whose end-points are [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex], then [tex]x=\frac{x_{1}+x_{2}}{2}[/tex] and [tex]y=\frac{y_{1}+y_{2}}{2}[/tex]
∵ JL is a segment
∵ The coordinates of J are (-6 , 1)
∴ [tex]x_{1}[/tex] = -6 and [tex]y_{1}[/tex] = 1
∵ The coordinates of L are (-4 , 3)
∴ [tex]x_{2}[/tex] = -4 and [tex]y_{2}[/tex] = 3
Lets use the rule above to find the mid-point of JL
∵ [tex]x=\frac{-6+-4}{2}=\frac{-10}{2}[/tex]
∴ x = -5
∴ The x-coordinate of the mid-point is -5
∵ [tex]y=\frac{1+3}{2}=\frac{4}{2}[/tex]
∴ y = 2
∴ The y-coordinate of the mid-point is 2
∴ The coordinates of the mid-point of JL are (-5 , 2)
Final answer:
The coordinates of the midpoint of the segment with endpoints J(-6, 1) and L(-4,3) are obtained by averaging the x and y coordinates of the endpoints, resulting in (-5, 2).
Explanation:
To find the coordinates of the midpoint of a segment with endpoints J(-6, 1) and L(-4,3), you use the midpoint formula which is ((x1 + x2)/2, (y1 + y2)/2). In this case, x1 is -6, x2 is -4, y1 is 1, and y2 is 3. Plugging these into the formula, we get the midpoint coordinates ((-6 - 4)/2, (1 + 3)/2) which simplifies to (-5, 2). Therefore, the midpoint of JL is at the coordinates (-5, 2).

Answer:
We'll use the Law of Sines:
Sine (C) / c = Sine (B) / b
Sine (86) / 40 = Sine (52) / b
0.99756 / 40 = 0.78801 / b
0.024939 = .78801 / b
b = .78801 / .024939
side b = 31.5974978949 feet
Sine (42) / a = Sine (86) / 40
(0.66913 / a) = 0.024939
a = .66913 / .024939
side a = 26.8306668271 feet

What is the sum of an arithmetic sequence?Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.
Then the sum of the arithmetic sequence will be
S = (n / 2)[a₁ + L]
S = (n/2) [2a + (n − 1) d]
The arithmetic sequence is given below.
2, 4, 6, 8, 10, .....
The first term is 2 and the common difference is 2. Then the sum of the first 100 even natural numbers will be
S = (100/2) [2 x 2 + (100 − 1) x 2]
S = 50 [4 + 99 x 2]
S = 50 [4 + 198]
S = 50 [202]
S = 10,100
The sum of the first 100 even natural numbers will be 10,100.

his season, Lisa's lacrosse team has won $\frac 23$ of their home games (games played at Lisa's school), but just $\frac 25$ of their away games (games played at other schools). In total, Lisa's team has won $26$ games out of $49$ games they have played. How many home games has Lisa's team played?
Solution:
Let "h" be the number of home games
Let "a" be the number of away games
The total number of games is 49
Therefore,
h + a = 49 ---------- eqn 1
They won 2/3 of the home games and 2/5 of the away games
There were 26 games won
Thus we get,
[tex]\frac{2}{3}h + \frac{2}{5}a = 26\\\\10h + 6a = 26 \times 15\\\\10h + 6a = 390\\\\[/tex]
10h + 6a = 390 --------- eqn 2
Multiply eqn 1 by 6
6h + 6a = 294 ----------- eqn 3
Subtract eqn 3 from eqn 2
10h + 6a = 390
6h + 6a = 294
( - ) ------------------
4h = 96
h = 24
Thus 24 home games were played
What is -9x+6=18 in slope intercept form ?
Answer:
y = 3/2 x + 3
Step-by-step explanation:
-9x + 6y = 18 is in standard form (ax + by = c).
Slope-intercept form isolates the "y" variable. It looks like this:
y = mx + b
Move anything that's not "y" to the right side. Move things in reverse BEDMAS order, using reverse operations of what you want to move.
[tex]-9x + 6y = 18[/tex] Move -9x by doing +9x to both sides
[tex]-9x + 9x + 6y = 18 + 9x[/tex] Simplify. -9x + 9x will cancel out.
[tex]6y = 18 + 9x[/tex] Move the "6" that multiplies with "y".
[tex]\frac{6y}{6} = \frac{18}{6} + \frac{9x}{6}[/tex] Divide each term by 6.
[tex]y = 3 + \frac{3x}{2}[/tex] "y" is isolated. Simplify the rest.
[tex]y = \frac{3}{2}x + 3[/tex] Rearrange to match slope-intercept form.

Graph each function.
Answer:
Step-by-step explanation:
We can recognize that the parent function for all of these graphs is going to be y=x^2. What this means is that we can graph y=x^2 and then apply transformations to it to get to all of these new graphs.
1. y = -x^2 + 5
We can see that the coefficient of the x^2 term is negative which tells us that the graph will now open downwards.
We also know that we are adding 5 on the outside of the argument which means it affect vertical shift. Therefore, we will be moving 5 units up.
2. y = x^2 - 4
We can see that the only change made to this equation is subtracting 4 on the outside of the squared part of the equation. Again, this signifies vertical movement, but since it's negative we will be moving the entire y = x^2 graph down 4 units.
3. y = -x^2 - 1
What do you notice about this graph?
- negative coefficient
- subtracting 1 outside of the argument
What do these mean?
- negative coefficient: opens downwards
- subtracting 1: move entire y = x^2 graph down 1 unit

Assignment - 4. Ratios, Rates, and Unit Rates
Attempt 1 of 2
Decide which unit rate is greatest and explain why using complete sentences.
• 12 apples for $4
• 21 apples for $8
• 35 apples for $14
• 45 apples for $16
WRITER
Answer:
3 apples per $ is the greatest unit rate when someone buy 12 apples for $4, because we are able buy more apples with this rate for the same price.
Step-by-step explanation:
As we know that unit rate can be calculated by dividing the two quantities having different units.
For example, Madrid has been champions 10 times in 30 seasons,
i.e. 10 champions / 30 seasons = 0.33 champions per season
and
Barcelona has been champions 5 times in 30 seasons.
i.e. 5 champions / 30 seasons = 0.16 champions per season
Thus, the champion rate for Real Madrid is greater than the champion rate for Barcelona. It means, Real Madrid has been a better team.
Now, let us check and answer the question.
12 apples for $4 means:12 apples / $4 = 3 apples per $
21 apples for $8 means:21 apples / $8 = 2.62 apples per $
35 apples for $14 means:35 apples / $14 = 2.5 apples per $
45 apples for $16 means:45 apples / $16 = 2.81 apples per $
From the above calculations and observation, we can conclude that 3 apples per $ is the greatest unit rate when someone buy 12 apples for $4.
This unit rate is the greatest because we are able buy more apples with this rate for the same price.
In other words, the rate is cheaper than the unit rate of the rest, because can buy more apples with this rate for the same price.

The five-number summary for a set of data is 10, 14, 15.5, 21, 25 what is the interquartile range of the data?
Answer:
7
Step-by-step explanation:
Q1 = 14
Q3 = 21
Take 21 - 14 and it gives you the interquartile range of 7.
Final answer:
The interquartile range (IQR) for the data set with a five-number summary of 10, 14, 15.5, 21, 25 is 7, calculated as the difference between the third quartile (Q3) and the first quartile (Q1), which are 21 and 14 respectively.
Explanation:
The interquartile range (IQR) of a data set is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). Given the five-number summary of 10, 14, 15.5, 21, 25, where 14 is Q1 and 21 is Q3, the IQR can be found using the formula:
IQR = Q3 - Q1
In this case:
IQR = 21 - 14
IQR = 7
Therefore, the interquartile range for this data set is 7.
An animal reserve has 28,000 elk. The population is at a rate of 15% per year. How long will it take for the population to reach 56,000?
Answer: In 5 years time the population will reach to 56,000.
Step-by-step explanation:
This can be calculated using yearly compound interest formula
Formula for yearly compound interest
CI = P(1+R/100)ⁿ
CI = 56,000
P = 28,000
R = 15%
n= number of years
Now,
56,000 = 28,000 (1+15/100)ⁿ
56,000 = 28,000 (1+.15)ⁿ = 28,000 (1.15)ⁿ
log (56,000/28,000) = n log(1.15)
log 2 = n log (1.15)
n = log 2/log 1.15
n≅ 5
