Answer:
27 children.
Step-by-step explanation:
We are told that at the newest animated movie, for every 9 children, there are 4 adults. There are a total of 39 children and adults at the movie.
We can see that number of children is proportional to number of adults. So we will use proportions to solve for number of children at the movie.
[tex]\frac{\text{Number of children}}{\text{Number of children + Adults}}=\frac{9}{4+9}[/tex]
[tex]\frac{\text{Number of children}}{\text{Number of children + Adults}}=\frac{9}{13}[/tex]
Let us substitute number of children and adults in our proportion.
[tex]\frac{\text{Number of children}}{39}=\frac{9}{13}[/tex]
Multiply both side of equation by 39.
[tex]39*\frac{\text{Number of children}}{39}=39*\frac{9}{13}[/tex]
[tex]\text{Number of children}=39*\frac{9}{13}[/tex]
[tex]\text{Number of children}=3*9[/tex]
[tex]\text{Number of children}=27[/tex]
Therefore, 27 children are at the movie.

A salesperson earns a salary of $700 per month plus 2% of the sales. Which inequality correctly represents the total sales if the salesperson is to have a monthly income of at least $1800?
x ≤ $45,000
x ≤ $55,000
x ≥ $55,000
x ≥ $45,000
Answer:
C. [tex]x\geq 55000[/tex]
Step-by-step explanation:
Let x be the total monthly sales.
We have been given that a salesperson earns a salary of $700 per month plus 2% of the sales. The salesperson want to have a monthly income of at least $1800.
This means that 700 plus 2% of total monthly sales should be greater than or equal to 1800. We can represent this information in an equation as:
[tex]700+(\frac{2}{100})x\geq 1800[/tex]
[tex]700+0.02x\geq 1800[/tex]
Let us solve our inequality to find the monthly sales (x).
Subtract 700 from both sides of our inequality.
[tex]700-700+0.02x\geq 1800-700[/tex]
[tex]0.02x\geq 1100[/tex]
Divide both sides of inequality by 0.02.
[tex]\frac{0.02x}{0.02}\geq \frac{1100}{0.02}[/tex]
[tex]x\geq \frac{1100}{0.02}[/tex]
[tex]x\geq 55000[/tex]
Therefore, the total monthly sales must be greater than or equal to 55,000 and option C is the correct choice.
The price of a pair of jeans was $45 after a 50% markup. What was the price of the jeans before the markup?
Answer:
$30
Step-by-step explanation:
Mark up is the profit on cost. if the pair of jeans was $45 after a 50% markup
Let the price of the jeans before the markup be p then;
p + 50%p = 45
1.5p =45
p = 45/1.5
p = 30
The price before mark up was $30, while the mark up or profit is $15. This shows 50% of the price before mark up.
(-2/3, sqrt5/3) is a point on a unit circle. Find the cosine, cosecant, and sine of the angle.
Look at the picture.
[tex]\csc\theta=\dfrac{1}{\sin\theta}=\dfrac{1}{\frac{y}{r}}=\dfrac{r}{y}[/tex]
We have the right triangle x, y and r. From the Pythagorean theorem we have:
[tex]r^2=x^2+y^2\to r=\sqrt{x^2+y^2}[/tex]
We have the point
[tex]\left(-\dfrac{2}{3};\ \dfrac{\sqrt5}{3}\right)[/tex]
Substitute:
[tex]r=\sqrt{\left(-\dfrac{2}{3}\right)^2+\left(\dfrac{\sqrt5}{3}\right)^2}\\\\r=\sqrt{\dfrac{4}{9}+\dfrac{5}{9}}\\\\r=\sqrt{\dfrac{9}{9}}\\\\r=1[/tex]
[tex]\csc\theta=\dfrac{1}{\frac{\sqrt5}{3}}=\dfrac{3}{\sqrt5}=\dfrac{3\cdot\sqrt5}{\sqrt5\cdot\sqrt5}=\boxed{\dfrac{3\sqrt5}{5}}[/tex]
The cosine of the angle is -2/3, the sine is √5/3, and the cosecant, being the reciprocal of the sine, is √5/5 after rationalization.
The point (-2/3,√5/3) on a unit circle represents the cosine and sine of a specific angle. Here, the x-coordinate is the cosine of the angle, and the y-coordinate is the sine of the angle.
Therefore, the cosine of the angle is -2/3, and the sine is √5/3.
To find the cosecant of the angle, we take the reciprocal of the sine, which gives us 3/√5 or √5/5 after rationalizing the denominator.

Lisa's favorite chocolate candies are wrapped in the shape of a triangular prism with shiny gold paper as shown below. If all sides of the package are covered in the gold paper, what is the surface area of the amount that is wrapped?
Answer:
Surface Area = 150
Step-by-step explanation:
The surface area of this triangular prism is the sum of area of all the sides.
Surface Area = triangle 1 (with base 8 and height 3) + triangle 2 (same as triangle 1) + lateral surface 1 (with length 7 and width 5 (calculation shown below)) + lateral surface 2 (same as lateral surface 1) + bottom (side not shown with length 7 and width 8)

Investment R R has a value of $ 4 0 0 $400 at the end of the first year and increases by 1 0 % 10% per year. Eric checks the value of his investments once a year, at the end of the year. What is the first year in which Eric sees that investment R R's value exceeded investment Q Q's value?
Answer: After 8 year from the first year Eric will see that investment R's value exceeded investment Q's value.
Step-by-step explanation:
Let after x year from the first year Eric sees that investment R's value exceeded investment Q's value.
Investment Q has a value of $ 500 at the end of the first year and increases by $ 45 per year.
Thus, after x year from the first year the total amount of Investment Q,
500 + 45 x
Similarly, after x year from the first year the total amount of Investment R,
⇒ [tex]400(1+\frac{10}{100} )^x = 400(1.1)^x[/tex]
Thus, [tex]500 + 45 x = 400(1.1)^x[/tex]
By plotting the equations in the graph,
We get, x = -6.178 or 8.069
But year can not be negative,
Therefore, x = 8.069
Thus, Approx after 8 year from the first year Eric will see that investment R's value exceeded investment Q's value.

in 2004, there were approximately 7100 cinema sites. In 2000, there were 8300.
Write an equation describing this relationship.
The relationship between the year and the number of cinema sites can be expressed with the linear equation y = -300x + 608300, where y is the number of cinema sites and x is the year. This equation was derived by calculating the slope and y-intercept using the points provided.
Explanation:The subject of the question falls into the domain of mathematics, specifically algebra. We are given two points on a line where the x-axis is the year and the y-axis represents the number of cinema sites. The two points are (2000, 8300) and (2004, 7100).
First, we need to calculate the slope, m: m = (y2 - y1) / (x2 - x1) = (7100 - 8300) / (2004 - 2000) = -1200 / 4 = -300.
The slope, -300, is the rate of change suggesting the number of cinemas decreases by 300 each year.
The equation of the line, or the linear equation, will be in the form y = mx + b. We now need to find the y-intercept (b) by substituting one of our points into the equation and solving for b.
If we use the point (2000, 8300): 8300 = -300*2000 + b. Solving for b gives b = 8300 + 600000 = 608300.
Therefore, the equation describing the relationship between the year and the number of cinema sites is y = -300x + 608300.

Paws at play made a total of $1,234 grooming 22 dogs. Paws at play charges $43 to groom each small dog and $75 for each large dog. Write a system of equations that can be used to determine the number of small and large dogs that were groomed
Step-by-step explanation:
We are asked to write a system of equations using our given information.
Let x be number of small dogs and y be number of large dogs.
We have been given that paws at play made a total of $1,234 grooming 22 dogs, which means that number of small dogs and large dogs is 22. We can represent this information as:
[tex]x+y=22...(1)[/tex]
We have been given that paws at play charges $43 to groom each small dog and $75 for each large dog. So the total grooming charges for grooming x small and y large dogs will be 43x+75y, that is equal to total charges for grooming $1234.
We can represent this information as:
[tex]43x+75y=1234...(2)[/tex]

Hence, Length of each of rope will be 9.93 feet.
Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x< or = to 110)
Answer:
97.8%
Step-by-step explanation:
110 is 2 standard deviations above the mean (6+6 = 12)
12+98 = 110
Looking at the standard deviation curve
P(x< or = to 110) = 1 - P(x>110)
We can find the probability that x>100 by adding anything above 2 standard deviations above the curve.
P(x>110) = 2.1+.1 = 2.2%
P(x< or = to 110) = 1 - P(x>110)
= 1- 2.2%
= 1- .022
= .978

Answer:
187.69 cm
Step-by-step explanation:
We have that the maximum area allowed for the painting = 3003.04 [tex]cm^{2}[/tex].
Also, the width of Carmen's painting = 16 cm.
It is required to maximum length of Carmen's painting that will be eligible to take part in the competition.
Let the maximum length of the painting = L cm.
Since, Area of a rectangle = length of the rectangle × width of the rectangle.
i.e. 3003.04 = L × 16
i.e. [tex]L=\frac{3003.04}{16}[/tex]
i.e. L = 187.69 cm
Hence, the length of the painting should not exceed 187.69 cm in order to be eligible to participate in the competition.

A herd of dinosaurs made paintings in the sand with their claws. Each baby dinosaur made 1515 paintings and each adult dinosaur made 77 paintings. The entire herd made 208208 paintings in total, and there were 33 times as many baby dinosaurs as adult dinosaurs. How many baby dinosaurs and adult dinosaurs were there?
Answer:
4 adult dinosaurs and 12 baby dinosaurs.
Step-by-step explanation:
Let the number of adult dinosaurs be x.
Number of baby dinosaurs = 3x
Number of paintings made by each baby dinosaur = 15
Number of paintings made by each adult dinosaur = 7
Total number of paintings made by 3x baby dinosaurs = Number of baby dinosaurs * Number of paintings made by each baby dinosaur
= 3x * 15
= 45x
Total number of paintings made by x adult dinosaurs = Number of adult dinosaurs * Number of paintings made by each adult dinosaur
= x * 7
= 7x
Total number of paintings made by both baby and adult dinosaurs = 45x + 7x
= 52 x
Again the problem says that the total number of paintings made = 208
So, 52x = 208
Dividing both sides by 52
[tex]\frac{52x}{52}[/tex] = [tex]\frac{208}{52}[/tex]
Cancelling out the 52's from the top and bottom on the left
x = 4
So, number of adult dinosaurs = 4
Number of baby dinosaurs = 3x = 3*4 = 12
A system of equations based on the information given can be used to find the number of baby and adult dinosaurs. The two equations are 1515b + 77a = 208208 and b = 33a. Solve these to find the number of each type of dinosaur.
Explanation:This problem can be solved by setting up a system of equations. Let's denote the number of baby dinosaurs as 'b' and the number of adult dinosaurs as 'a'. Then, from the statement, we know two things:
'Each baby dinosaur made 1515 paintings and each adult dinosaur made 77 paintings. The entire herd made 208208 paintings in total, we can set up the equation as 1515b + 77a = 208208.'There were 33 times as many baby dinosaurs as adult dinosaurs', so this can be represented as b = 33a.By substituting the second equation into the first, we can determine the number of adult dinosaurs, and subsequently, the number of baby dinosaurs. Solving this would give us the solution needed.

Jayda is cutting a roll of biscuit dough into slices that are 3/4 inches thick if the roll is 10 1/2 inches long how many slices can he cut?
Answer:
Jayda can cut 14 slices of dough that are 3/4 inches thick.
Step-by-step explanation:
In order to solve this problem, we need to take the total amount of dough at 10 1/2 inches and divide it by the thickness of one slide, 3/4 inches, to find the number of slices that can be made from the total amount. You can solve this two different ways. You can either convert your fractions to decimals so that 10 1/2 becomes 10.5 and 3/4 become 0.75 and then divide 10.5/0.75 to get 14. However, you can also keep them as fractions converting 10 1/2 to 21/2 and dividing by 3/4. When we divide with fractions with keep-change-flip, or keep the first fraction-change the sign to multiplication-flip the second fraction. So, we multiply 21/2 x 4/3 and get 84/6, or 14.
What is the inverse of f(x)=(x-5)^2 for x greater or equal to 5 where function g is the inverse of function f
The inverse function of f(x) = (x - 5)² for x greater or equal to 5 is g(x) = sqrt(x) + 5.
Explanation:The function f(x) = (x - 5)² for x greater or equal to 5 has a specific inverse function denoted as g(x). To find the inverse of a function, one typical solution is to replace f(x) with y, swap x and y, and solve for y. Here, it means writing y = (x - 5)², changing it to x = (y - 5)², and solving for y.
The solved y function is g(x) = √(x) + 5 (where sqrt indicates a square root), ensuring the range for x is greater than or equal to 5 to adhere to the original function constraints.

Mr robbins earns a commission on each airfare he books. At the end of the day,he had booked $208.60 worth if airfare and earned $31.29. Approximately what is Mr. Robins commision rate.
Answer:
Mr. Robins commision rate is 15%.
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
As given
Mr robbins earns a commission on each airfare he books.
At the end of the day,he had booked $208.60 worth if airfare and earned $31.29.
Here
Part value = $31.29
Total value = $208.60
Put in the formula
[tex]Percentage = \frac{31.29\times 100}{208.60}[/tex]
[tex]Percentage = \frac{312900}{20860}[/tex]
Percentage = 15%
Therefore the Mr. Robins commision rate is 15%.
Solve by elimination
2x-y=0
3x-2y=-3
To solve a system of equations by elimination, make the coefficients of one variable equal. Subtract one equation from the other to solve for one variable, then substitute this solution into one of the original equations to solve for the other variable. In this case, the solution to the given system of equations is x = 3, y = 6.
Explanation:In mathematics, specifically in algebra, the method of elimination is used to solve a system of simultaneous equations. Your equations are:
2x -y = 03x - 2y = -3To solve this system by elimination, we need to make the coefficients of y in both equations equal by multiplying if necessary. We can obtain this by multiplying the first equation by 2:
4x - 2y = 0
3x - 2y = -3
Next, we subtract one equation from the other to eliminate y:
4x - 3x = 0 - (-3) => x = 3
To find y, substitute x = 3 into the first equation:
2*3 - y = 0 => y = 2*3 = 6
So, the solution to the system of equations is x = 3, y = 6.

Answer: 1%
Explanation:
Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000
There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.
Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
