How far, to the nearest foot, does a horse on a Merry-Go-Round travel in one revolution if he is 6.5 feet from the center? (Use 3.14 for π)
A) 26 feet
B) 39 feet
C) 41 feet
D) 56 feet
Answer:
c
Step-by-step explanation:
I'm pretty sure it's asking for the circumference. The formula for finding the circumferene is C=πd (d=diameter) First, you need to fiind the diameter. Thequestion gives you the radius, 6.5, which is half the diameter. multiply that by 2 and you get 13. The question says to use 3.14 as π, so just multiply 3.14 by 13 and you get 40.82, which rounds to 41.
What is the volume of the sphere, rounded to the nearest cubic foot?
Given:
Radius = 5 ft
To find:
The volume of the sphere
Solution:
Volume of the sphere:
[tex]$V=\frac{4}{3}\pi r^3[/tex]
[tex]$V=\frac{4}{3}\times 3.142 \times 5^3[/tex]
[tex]$V=523.66[/tex]

Solving systems of equations using any method
Final answer:
To solve the system of equations, use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite. Add the two equations together to eliminate 'x' and solve for 'y'. Substitute the value of 'y' into one of the original equations and solve for 'x'. The solution to the system of equations is x = -5/2 and y = -1.
Explanation:
To solve the system of equations:
4x + 9y = -19
-4x - 7y = 13
We can use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite:
16x + 28y = -52
Now, add the two equations together to eliminate 'x':
37y = -39
Divide both sides by 37:
y = -1
Substitute the value of 'y' into one of the original equations:
4x + 9(-1) = -19
4x - 9 = -19
Add 9 to both sides:
4x = -10
Divide both sides by 4:
x = -10/4 = -5/2
Therefore, the solution to the system of equations is x = -5/2 and y = -1.
The angle θ=π3 is in standard position and has a terminal side that coincides with the graph of a proportional relationship represented by y=kx.
a. Find the constant of proportionality, k.
b. Write an ordered pair that lies on the graph of y=kx.
Part a
theta = pi/3
sin(pi/3) = sqrt(3)/2
cos(pi/3) = 1/3
tan(angle) = opposite/adjacent = rise/run = slope
tan(pi/3) = sin(pi/3)/cos(pi/3) = (sqrt(3)/2)/(1/2) = sqrt(3)
The value of k is k = sqrt(3)This is also the slope the line y = kx because it is in the form y = mx+b with m = sqrt(3) and b = 0.
===============================================
Part b
Pick any value you want for x, and plug it in to find the paired value of y
if x = 0, then y = 0 because
y = sqrt(3)*x = sqrt(3)*0 = 0
So (0,0) is one ordered pair on the line---------
If x = 1, then y = sqrt(3), since,
y = sqrt(3)*x = sqrt(3)*1 = sqrt(3)
We can say ( 1, sqrt(3) ) is another ordered pair---------
If x = sqrt(3), then,
y = sqrt(3)*x = sqrt(3)*sqrt(3) = sqrt(3*3) = sqrt(9) = 3
Therefore, ( sqrt(3), 3 ) is another ordered pairThere are infinitely many ordered pairs on this line.12y=24x
6x=3y+5
Which statement best describes the relationship between the lines?
Answer: i think is A they are parallel
Step-by-step explanation: is not perpendicular NOT-B
The relationship between the lines represented by the equations 12y = 24x and 6x = 3y + 5 is that they are parallel lines. This conclusion is drawn from the fact that they have the same slope (2) but different y-intercepts (0 for the first line and -5/3 for the second line).
Explanation:To determine the relationship between the lines represented by these equations, we must first put them in slope-intercept form (y = mx + b), where m represents the slope of the line, and b indicates the y-intercept.
For the first equation, 12y = 24x, we can divide both sides of the equation by 12 to get y = 2x.
For the second equation, 6x = 3y + 5, we re-arrange the equation by subtracting 5 from both sides and then dividing by 3. This gives us y = 2x - 5/3.
From the equations y = 2x and y = 2x - 5/3, we can see that the slopes of both lines are the same which is 2. This indicates that the lines are parallel to each other. However, since the y-intercepts are different (0 for the first line and -5/3 for the second line), we can conclude that they are different parallel lines, not the same line.

Mr.O'Connor had $90 to spend at a football game. He spent 31/45 on his ticket. Then, he spent 3/7 of his remaining money at the concession stand. While walking back to his seat, he saw a new hat on sale for $18. Did Mr. O'Connor have enough money left to buy the hat?
I am not sure what to do.
Answer:
no
Step-by-step explanation:
he starts with 90 bucks to find what the fraction represents you can multiply it by 2 to get an equal denominator of 90 then subtract 90-62 that'll give you 28 then it says he spent 3/7 so you do the same thing get an equal denominator by multiplying by 4 and get 28 and as they say whatever you do to the denominator is done to the numerator so 3 times 4 is 12 then you do 28-12 and you gets 16 which isn't enough to buy the hat. :)

Given:
Students from Williams Middle School are also recycling aluminum cans. The data for the numbers of cans brought in each school day for a month were divided by quartiles and summarized in the box plot.
We need to determine the Median, Interquartile range and Range.
Median:
The median is the middle value of the given set of data.
From the box plot, it is obvious that the median line is at 18.
Thus, Median = 18
Hence, the value of the median is 18.
Interquartile range:
The interquartile range is can be determined by finding the difference between the ends of the box in the box plot.
From the box plot, we have;
Interquartile range = 20 -16
Interquartile range = 4
Hence, the value of the interquartile range is 4.
Range:
The range can be determined by subtracting the highest and the lowest value in the given set of data.
From the box plot, the range can be determined by subtracting the ends of the line.
Thus, we have;
Range = 28 - 10
Range = 18
Hence, the value of the range is 18.
Answer:
Median: 18
Interquartile range: 4
Range: 18

Jackie cut a piece of paper along its diagonal, as shown below, forming two triangles.
A rectangle is cut diagonally to form 2 equal triangles.
How do the height and base length of the two triangles compare to the height and base length of the original piece of paper?
The two dimensions are the same in the triangles as they were in the rectangle.
The two heights are the same in the triangles as they were in the rectangle, but the bases of the triangles are half the length of the base of the rectangle.
The two bases of the triangles have the same length as the base of the rectangle, but the triangles have heights equal to half the height of the rectangle.
The two dimensions of the triangles are each half what they were in the rectangle.
Answer:
B. The two dimensions are the same in the triangles as they were in the rectangle.
Step-by-step explanation:
Given
Initial Shape: Rectangle (Before cut)
Final Shape: Triangles (After cut)
Note that this can be explained properly with the use of attachments
See attachment 1 for Before Cut
Before Cut represent the full rectangle before Jackie cut the piece of paper.
Let H and B represent the height and base of the triangle
Given that the rectangle is cut diagonally, this means that the cutting starts and ends at the opposite edges of the rectangle
See attachment 2 for After Cut
After Cut represent the two triangles after cutting the rectangle
From the attachment, you'll observe that the dimension of the two triangles (Triangle 1 and Triangle 2) are the same as it is with the rectangle;
In other words, the two triangle have their heights as H and their bases as B.
Hence, it can concluded that the two dimensions are the same in the triangles as they were in the rectangle.

Taylor Breen took out a $100,000, 5-year term policy at age 48. The premium per $1,000 was $4.70. He will be 53 years old next year when the premium per $1,000 will be $6.40. What is the amount of the increase?
Select one:
a. $133
b. $136
c. $173
d. $170
To find the amount of the increase, calculate the difference in premiums per $1,000 between when Taylor Breen took out the policy at age 48 and when he will be 53 years old next year. The amount of the increase is $170.
Explanation:To find the amount of the increase, we need to calculate the difference in premiums per $1,000 between when Taylor Breen took out the policy at age 48 and when he will be 53 years old next year.
First, let's calculate the initial premium per $1,000 at age 48:
$100,000 / $1,000 = 100 (number of units)
$100,000 * $4.70 = $470,000 (initial premium)
Next, let's calculate the premium per $1,000 when Taylor Breen will be 53 years old:
$100,000 / $1,000 = 100 (number of units)
$100,000 * $6.40 = $640,000 (premium at age 53)
The amount of the increase is:
$640,000 - $470,000 = $170,000
Therefore, the amount of the increase is $170.

Factor completely 3x^2+33x+90=?
Answer:
3(x+5) (x+6)
Step-by-step explanation:
The factored form of 3x² + 33x + 90 is: 3(x + 6)(x + 5)
To factor completely the quadratic expression 3x² + 33x + 90, we can look for two binomial factors that multiply together to give us the original expression.
First, we can check if the expression can be factored by using the common factor 3:
3x²+ 33x + 90
We can factor out 3 from each term:
3(x^2 + 11x + 30)
Now, we need to find two binomial factors that multiply to give us x² + 11x + 30.
The factors can be determined by factoring the quadratic expression further:
x² + 11x + 30 = (x + 6)(x + 5)
Therefore, the completely factored form of 3x² + 33x + 90 is:
3(x + 6)(x + 5)

Find the volume of a triangular pyramid with a base height of 5 inches, base length of 3 inches, and a height of 6 inches.
Final answer:
The volume of the triangular pyramid is calculated by finding the area of the triangular base and then using the volume formula for a pyramid, resulting in a volume of 15 cubic inches.
Explanation:
To find the volume of a triangular pyramid, we use the formula for the volume of a pyramid, which is V = (1/3) × base area × height. First, calculate the area of the triangular base using the formula for the area of a triangle, A = (base length × base height) / 2. In this case, the base length is 3 inches, and the base height is 5 inches.
Therefore, the area of the triangle is A = (3 in. × 5 in.) / 2 = 7.5 in.². Now, we can calculate the volume of the pyramid using the height of the pyramid, which is 6 inches.
The volume of the pyramid is V = (1/3) × 7.5 in.² × 6 in. When you calculate this, you get V = 15 in.³, which is the volume of the pyramid.
