To find out how many children and how many adults attended the event, we can set up a system of equations based on the given information.
Let's use the variables c and a to represent the number of children and adults, respectively. The total number of people who attended the event is 100, and the total amount collected at the door is $626. Each child ticket costs $5, and each adult ticket costs $8. By setting up and solving a system of equations, we can determine the values of c and a.
Let c represent the number of children and a represent the number of adults who attended the event. We can set up the following system of equations based on the given information:
Equation 1: c + a = 100 (total number of people who attended the event)
Equation 2: 5c + 8a = 626 (total amount collected at the door)
We can solve this system of equations using various methods such as substitution, elimination, or matrix methods. Here, we'll solve it using the substitution method.
From Equation 1, we have c = 100 - a. Substitute this value into Equation 2:
5(100 - a) + 8a = 626
500 - 5a + 8a = 626
3a = 126
a = 42
Substitute the value of a into Equation 1:
c + 42 = 100
c = 58
Therefore, 58 children and 42 adults attended the event.

What is the value of n when 3/5 of n is 27? Enter answer in the box
n = 45 satisfies the equation, and it is the value that makes 3/5 of n equal to 27. The value of n can be determined by setting up an equation based on the given information that 3/5 of n is equal to 27.
By solving the equation, we can find the value of n. Let's set up the equation based on the given information:
(3/5) * n = 27
To solve for n, we need to isolate n on one side of the equation. We can do this by multiplying both sides of the equation by the reciprocal of 3/5, which is 5/3:
n = 27 * (5/3)
Simplifying the right side of the equation:
n = (27 * 5) / 3
n = 135 / 3
n = 45
Therefore, the value of n is 45. We can confirm this by substituting n = 45 back into the equation:
(3/5) * 45 = 27
(3/5) * 45 = 135/5 = 27

What is the following product? (StartRoot 14 EndRoot minus StartRoot 3 EndRoot) (StartRoot 12 EndRoot StartRoot 7 EndRoot).
Let's solve the new math question you provided.
To simplify the product (√14 - √3)(√12 √7), we can apply the distributive property.
(√14 - √3)(√12 √7) = √14 * √12 √7 - √3 * √12 √7
To simplify the square roots, we can use the property √(a * b) = √a * √b.
= √(14 * 12) * √7 - √(3 * 12) * √7
= √168 * √7 - √36 * √7
Now, we can simplify the square roots further. √168 = √(4 * 42) = 2√42, and √36 = 6.
= 2√42 * √7 - 6√7
= 2√(42 * 7) - 6√7

Karen drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (−1.3,−3.1), (−1.3,1.2), and (1.1,1.2). What are the coordinates of the fourth vertex?
The coordinates of the fourth vertex are (1.1, -3.1).
We know that a rectangular piece of material has two pairs of parallel sides and four right angles. Therefore, we can calculate the distance between two opposite sides by using the distance formula. The two sides that are parallel to the x-axis have the same y-coordinate, and the two sides parallel to the y-axis have the same x-coordinate.
Thus, the distance between opposite sides is given by the difference between the x-coordinates or the difference between the y-coordinates. The x-coordinates of the vertices are −1.3, −1.3, and 1.1. So the difference between them is 1.1 − (−1.3) = 2.4. The y-coordinates of the vertices are −3.1, 1.2, and 1.2. So the difference between them is 1.2 − (−3.1) = 4.3. The fourth vertex is located at the point with an x-coordinate of 1.1 and a y-coordinate of −3.1. Therefore, the coordinates of the fourth vertex are (1.1, -3.1).

Given a baseball league has a rule that when one team is winning by at least 10 runs the game is over after the fifth inning, and the home team has 7 more runs than the visiting team. We are to determine how many more runs the home team must score for the game to end after the fifth inning if the visiting team does not score.
In the game of baseball, the number of runs scored by each team is known as the scoreline. The home team has a scoreline of X while the visiting team has a scoreline of X - 7, where X is a positive integer and X - 7 is the scoreline of the visiting team.
Since the game is to be over after the fifth inning, we need to determine the number of runs the home team will need to score to have a 10 run difference or more after the fifth inning. Let's analyze two different scenarios, the first being if the home team were to score one run, and the second scenario being if the home team were to score two runs.
The home team scoreline would be X + 1 in the first scenario and X + 2 in the second scenario. In both cases, the visiting team does not score any additional runs. Thus, the scoreline of the visiting team remains X - 7 in both scenarios.
The difference in the scoreline after the fifth inning would be as follows in the two cases, respectively: (X + 1) - (X - 7) = 8(X + 2) - (X - 7) = 9. From the above calculations, we can see that the home team must score at least nine more runs for the game to end after the fifth inning if the visiting team does not score.
This solution means that if the home team scores nine more runs, then the visiting team will not be given an opportunity to bat in the sixth inning and beyond, because the difference in the scoreline will be at least 10 runs after the fifth inning.

The solution to the equation is x is less than 1.
Let's assume the number as "x".
The given statement can be translated into an equation as follows:
3 - 11x > 21 - 5x
To solve this equation, we can start by simplifying both sides:
3 - 11x > 21 - 5x
Next, let's gather the terms with x on one side and the constant terms on the other side by adding 11x and subtracting 21 from both sides:
3 - 11x + 11x - 5x > 21 - 5x + 11x - 21
Simplifying further, we get:
-16x > -x
Now, we can divide both sides by -16, but since we are dividing by a negative number, we need to reverse the inequality sign:
-16x / -16 < -x / -16
x < 1

I know the answer is 9 but how do i get that?
9 kilograms of cashews were in the mixture the grocer sold.
To solve the given problem, let x represent the number of kilograms of cashews.
Hence, the number of kilograms of Brazil nuts would be (12 - x) as the grocer sold 12 kg of the mixture.
Therefore, the cost of the cashews at $8 per kilogram is 8(x)
and the cost of the Brazil nuts at $10 per kilogram is 10(12 - x).
Hence, the cost of the mixture at $8.50 per kilogram is:
8.5*(12) = 8(x) + 10(12 - x)

The amount of money that Ben gets is £140.
Let's denote the amount Abby gets as 2x. Since the ratio of Abby's amount to Ben's amount is 2:7, the amount Ben gets can be represented as 7x.
Chloe and Denesh each get 1.5 times the amount Abby gets, which means they each get 1.5 * 2x = 3x.
The total amount shared between Abby, Ben, Chloe, and Denesh is £360. So we can write the equation: 2x + 7x + 3x + 3x = £360.
Simplifying the equation, we have: 15x = £360.
Dividing both sides by 15, we find that x = £24.

A Mad Professor has created a new kind of creature called a Blorg. For each Blorg, one hour after it is born, it gives birth to a new Blorg. Two hours after it is born, it gives birth to two more new Blorgs and then it immediately dies. If the Professor starts with one newborn Blorg at noon, how many live Blorgs does he have at 4:05 PM that afternoon after the new Blorgs have been born and the 2-hour-olds have died?
Blorgs have a lifespan of two hours, and after that, they die. The newborn Blorgs continue the reproductive cycle, but all Blorgs born before 3 PM would have reached their lifespan and died by 4:05 PM.
To determine the number of live Blorgs the Mad Professor has at 4:05 PM, we need to understand the pattern of Blorg reproduction and lifespan.
From the given information, we know that one hour after a Blorg is born, it gives birth to a new Blorg. Two hours after birth, it gives birth to two more new Blorgs and then immediately dies.
Let's break down the timeline:
At noon, the Professor has one newborn Blorg.
One hour later, at 1 PM, the initial Blorg gives birth to a new Blorg. So, there are two Blorgs now.
Two hours after birth, at 2 PM, the initial Blorg dies, but the newborn Blorg from 1 PM gives birth to two more Blorgs. So, there are four Blorgs now.
At 3 PM, the two newborn Blorgs from 1 PM give birth to two more Blorgs each, resulting in a total of eight Blorgs.
At 4 PM, the four Blorgs that were born at 2 PM die, while the four Blorgs born at 3 PM are still alive. The four living Blorgs are from the second generation.
Now, let's calculate the number of live Blorgs at 4:05 PM:
At 4 PM, there are four living Blorgs.
Since each Blorg lives for two hours, at 4:05 PM, it has been 5 minutes past their lifespan, and all the living Blorgs from the 3 PM generation would have died.
Therefore, at 4:05 PM, the Mad Professor would have zero live Blorgs.
It is important to note that Blorgs have a lifespan of two hours, and after that, they die. The newborn Blorgs continue the reproductive cycle, but all Blorgs born before 3 PM would have reached their lifespan and died by 4:05 PM.

Which histogram depicts a higher standard deviation.
Histograms visualize the distribution and spread of data. A higher standard deviation implies greater variability in the data points. In a histogram, a wider shape indicates a larger spread of data and thus a higher standard deviation. Therefore, the histogram with a broader shape depicts a higher standard deviation.
To determine which histogram depicts a higher standard deviation, we need to look for the histogram with a greater spread or dispersion of data. In a histogram, a higher standard deviation indicates that the data points are more spread out or have a larger variability. This means that the values are more scattered from the mean. Therefore, the histogram with a wider and more spread-out shape would depict a higher standard deviation, as it indicates a greater variability in the data.

if BAT is congruent to DOG and angle B equals 14 angle G equals 29 and angle O is equal to 10 X +7 find X and angle O
The value of X is 7/10 and the measure of angle O is 14. Angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
To find the value of X and the measure of angle O, we need to use the information provided about the congruent triangles BAT and DOG and the measures of angles B, G, and O.
Given that BAT is congruent to DOG, we know that their corresponding angles are equal.
From the given information, angle B is equal to 14 and angle G is equal to 29.
Therefore, angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
We are also given that angle O is equal to 10X + 7.
Setting up an equation, we have:
10X + 7 = 14
To solve for X, we subtract 7 from both sides:
10X = 14 - 7
10X = 7
Dividing both sides by 10:
X = 7/10
Thus, X is equal to 7/10.
Therefore, the value of X is 7/10 and the measure of angle O is 14.

Let b cannot equal 1 and consider the integral 1 to b (6x-9) dx a) what value of b will make this integral equal to 0? b) sketch a graph of y=6x-9 on the interval from x=1 to x=b to verify your answer in (a)
a) To find the value of b that makes the integral equal to 0, we need to solve the integral:
∫(1 to b) (6x - 9) dx = 0
Applying the fundamental theorem of calculus, we can find the antiderivative of the integrand and evaluate it at the limits of integration:
[3x² - 9x] (from 1 to b) = 0
Substituting the limits, we have:
(3b² - 9b) - (3(1)² - 9(1)) = 0
Simplifying further:
3b² - 9b - 6 = 0
Now we can solve this quadratic equation for b using the quadratic formula or factoring:
b² - 3b - 2 = 0
Factoring the quadratic equation, we get:
(b - 2)(b + 1) = 0
Setting each factor to zero, we find two possible values for b:
b = 2 or b = -1.
However, since b cannot equal 1 (as stated in the problem), the only valid solution is b = 2.
b) To verify our answer, we can sketch a graph of y = 6x - 9 on the interval from x = 1 to x = b = 2. The graph will be a straight line with a slope of 6 and y-intercept at -9.
On the interval [1, 2], the line starts at the point (1, -3) and ends at the point (2, 3). By calculating the area under this line, we find that the integral from 1 to 2 of (6x - 9) equals 0, confirming our previous result.

Milo wants to make a mixture that is 50% lemon juice and 50% lime juice. How much 100% lemon juice should he add to a juice mixture that is 20% lemon juice and 80% lime juice to make 4 gallons of the 50% lemon/50% lime juice mixture? 0. 5 gallon 1. 5 gallons 2 gallons 2. 5 gallons.
To solve this problem, we can set up an equation based on the volume of lemon juice in the mixture:
Let's assume Milo needs to add x gallons of 100% lemon juice.
The total volume of the final mixture is given as 4 gallons, and it should be a 50% lemon juice and 50% lime juice mixture.
The initial mixture contains 20% lemon juice, which means it contains 20% of 4 gallons = 0.2 * 4 = 0.8 gallons of lemon juice.
So, the equation becomes:
0.8 gallons (initial lemon juice) + x gallons (additional 100% lemon juice) = 0.5 * 4 gallons (final lemon juice)
Simplifying the equation:
0.8 + x = 2
Subtracting 0.8 from both sides:
x = 2 - 0.8
x = 1.2
Therefore, Milo needs to add 1.2 gallons of 100% lemon juice to make 4 gallons of the 50% lemon/50% lime juice mixture.
