Answer:
A. 11.25
Step-by-step explanation:
If point C(x, y) divides line segment AB with end points at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2\\[/tex]) in the ratio on n:m, then the coordinates of point C is:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
Given that segment AB is divided by point C in the ratio of 3:1. Given A(3, 12) and B (14, 17). Let coordinate of C be (x, y), hence:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1\\\\x=\frac{3}{3+1}(14-3)+3=\frac{3}{4}(11)+3=11.25 \\\\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\\\\y=\frac{3}{3+1}(17-12)+12=\frac{3}{4}(5)+12=15.75[/tex]
Therefore, the coordinate of point C = (11.25, 15.75)
The x coordinate of point C is 11.25
Savannah gave the cashier $20 to pay for 3 pairs of socks. The cashier gave her $5.03 in change. Each pair of socks cost the same amount. What is the cost in dollars and cents for each pair of socks? Once you solve the problem, circle/highlight your answer.
Answer: $4.99
Step-by-step explanation:
The amount that Savannah paid for the 3 pairs of socks will be gotten by subtracting $5.03 from $20 which will be:
= $20 - $5.03
= $14.97
Since each paid of socks cost thesame amount, the cost of each pair of socks will be:
= $14.97/3
= $4.99
Each pair of socks cost $4.99

Answer:
181 mi^2
Step-by-step explanation:
Dimensions of large rectangle, on the left, are 6 mi by 8 m; area is 48 m^2;
Dimensions of small rectangle, in the middle of the diagram, are 4 mi by 5 mi, or 20 mi^2; area is 20 mi^2.
Dimensions of circle: r = 12 mi; area of quarter circle is (1/4)(3.14)(12 mi)^2, or 113 mi^2.
Total area is 113 mi^2 + 20 mi^2 + 48 mi^2, or 181 mi^2
Answer:
Step-by-step explanation:
So first off. lets take chunks of this shape. We have a 6x8 rectangle, a 4x5 rectangle, and a 1/4 circle with a radius of 12.
The area of a rectnagle is just length x width.
So lets plug in our values for our two ractnagles, and see what we get:
6*8
=
48
So our first rectangle has a area of 48
Next we have:
4*5
=
20
So our second rectangle has an area of 20.
Add these otgether you get 68.
Finally we have our 1/4 circle. To solve this, find the area of the full circle and divide by 4.
We already know the radius, which is 12, and the formula for area of a circle is:
a=πr^2
Plug in 12:
a=π12^2
=
a=π144
dividing by four for the 1/4circle:
a=π36
So this means your answer is either:
68 +36π
Or:
181.097(solving pi*36)
Either of these work, if the problem allows pi, then use the first one, If not, use the bottom one.

Find the median of the data in the box plot below. Cookies A horizontal boxplot titled Number of cookies eaten by each contestant, is plotted along a horizontal axis marked from 2 to 30, in increments of 1. A left whisker extends from 5 to 6. The box extends from 6 to 22 and is divided into 2 parts by a vertical line segment at 8. The right whisker extends from 22 to 25. All values estimated.
Diagrammatic representation of the summarized box plot is attached below :
Answer:
Range = 20
Median = 8
Step-by-step explanation:
The median value of a box plot is obtained at the point where a vertical line divides the box into two parts. In the boxplot Given the median of the representation is 8. This is the point where the vertical line divides the box.
The range of the distribution is the difference between the maximum and minimum value :
Minimum (starting point of whisker) = 5
Maximum (end point of whisker) = 25
Range = 25 - 5 = 20

A rectangular garden has length twice as great as its width. A second rectangular garden has the same length as the first garden and width that is 4 meters greater than the width of the first garden. The second garden has area of 120 square meters. What is the length of the two gardens? Enter your answer in the box. m=
Answer:
24 meters
Step-by-step explanation:
First we need to show width and length as variables.
let width of garden 1 = W
let length of garden 1 = L
let width of garden 2 = w
let length of garden 2 = l
Now make equations that are explained in the question
L = 2W
l = L
w = W + 4
l × w = 120
Now with that we can find l and w.
Now by looking at the factors of 120, find the factors that work throughout the question.
That is 12 and 10.
l=12
w=10
This means that...
L=12
W=6
Now the answer is 24 meters

Answer:
The correct answer is C.
Step-by-step explanation:
In the equation of a circle, if the variable [tex]x[/tex] and [tex]y[/tex] are added or subtracted by any number before being squared, the entire circle with be translated in the opposite amount that was added or subtracted to the circle. For example, [tex](x-8)^2 + (y-8)^2[/tex] shifts the center 8 to the right and up of the origin, [tex](x+1)^2+(y+4)^2[/tex] shifts the center 1 to the left and 4 down of the origin. Since the circle represented in the graph is centered directly on the origin, that means the equation will have [tex]x^2+y^2[/tex], which helps you eliminate choices A and C. For the equation of a circle, the radius is the value of the constant on the right side of the equal sign taken to its square root. Since the radius of this circle is 8, that means the constant at the right side of the circle would be 64 or [tex]8^2[/tex], so the correct answer would be choice C: [tex]x^2+y^2=8^2[/tex].

how do you find the height of a triangle (to calculate area)?
Answer:
The height of the triangle could be found by the Pythagoras theorem, where the result is, with the data of the exercise:
Height of the triangle = 10.392And the area of the triangle is:
Area of the triangle = 31.176 units^2Step-by-step explanation:
When you have two measurements of a triangle, as the case in the picture, you can find the third with the Pythagoras theorem, which is:
(opposite leg)^2 + (adjacent leg)^2 = hypotenuse^2As you can see in the picture, the measurement of the hypotenuse is 12, and the opposite leg could be 6, for this reason, we're gonna clear the adjacent leg of the formula above:
(opposite leg)^2 + (adjacent leg)^2 = hypotenuse^2(adjacent leg)^2 = hypotenuse^2 - (opposite leg)^2Now, we can replace the values in the formula obtained:
(adjacent leg)^2 = hypotenuse^2 - (opposite leg)^2(adjacent leg)^2 = 12^2 - 6^2(adjacent leg)^2 = 144 - 36(adjacent leg)^2 = 108Now, as we just need the adjacent leg, we take the square root of both sides:
adjacent leg = [tex]\sqrt{108}[/tex]adjacent leg = 10.392 approximately.Now, with these data, we can find the area of the triangle with the next formula:
Area of a triangle = (base * height) / 2And we replace the measurements:Area of a triangle = (6 * 10.392) / 2Area of a triangle = 31.176As the image does not contain units, it would be simply this number, however, you should know that the area units are usually given squared, for example: in^2 or ft^2.

What is the center and radius of the following
circle:
(x +4)2 + (-2) = 4?
Answer:
x = -1
Step-by-step explanation:
Answer:
That is not a circle; it has no y term
My guess:
center = (h, k) = (-4, 2)
r = √4 = 2
Step-by-step explanation:
If I had to guess what you intended:
(x + 4)² + (y - 2)² = 4
The standard equation for a circle is
(x - h)² + (y - k)² = r²
(h, k) is the center and r is the radius
center = (h, k) = (-4, 2)
r = √4 = 2
Solve for X please help
Answer:
x = 10
Step-by-step explanation:
First square both sides of the equation...

Find the are of this compound shape below *
Answer:
52 cm²
Step-by-step explanation:
First, we find the area of the bottom rectangle. We see it's 4 high and 10 wide, so 4x10 is 40. Then, we see that the small figure in the top right has a height of 4 and width of 3, so 4x3 = 12, add those and you get 52.
Find the value of x in the isosceles triangle shown below
Answer:
The answer is 12
Hope it helps
Answer:
x = 12
Step-by-step explanation:
Since the 2 legs and base angles are congruent the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector dividing the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles with legs 3 and [tex]\frac{1}{2}[/tex] x , hypotenuse [tex]\sqrt{45}[/tex] , then
([tex]\frac{1}{2}[/tex] x )² + 3² = ([tex]\sqrt{45}[/tex] )²
[tex]\frac{1}{4}[/tex] x² + 9 = 45 ( subtract 9 from both sides ²)
[tex]\frac{1}{4}[/tex] x² = 36 ( multiply both sides by 4 to clear the fraction )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12

Determine which lines are parallel and which are perpendicular. Explain your reasoning.
Answer:
Parallel: a and b, p and q, p and r, q and r
PErpendicular: p&a, p&b, q&a, q&b, r&a, r&b
Step-by-step explanation:
Parallel lines have the same slope so both of the lines would be going in the same direction and will never cross each other.
Perpendicular lines cross at a 90 degree angle.
Technically you do not know if q&a and q&b are perpendicular because you do not know if there is a 90 degree angle
Answer:
Parallel lines are equally spaced out in the same direction so it would be p,q, and r, Purpendicular Lines intersect at a 90 degee angle so it would be q and a, q and b, r and b, and r, and so on
Step-by-step explanation:
The quality control manager of at Long John Silver's restaurant wants to analyze the length of time that a car spends at the drive-thru window waiting for an order. It is determined that the mean time spent at the window is 59.3 seconds with a standard deviation of 13.1 seconds. The distribution of time at the window is skewed right. The quality control manager wishes to use a new delivery system designed to get cars through the drive-thru system faster. A random sample of 40 cars results in a sample mean time spent at the window of 56.8 seconds. What is the probability of obtaining a sample mean of 56.8 seconds or less, assuming that the population mean is 59.3 seconds
Answer:
0.11314
Step-by-step explanation:
The Long John Silver's restaurant parameters are;
The mean time spent at the window, μ = 59.3
The standard deviation, σ = 13.1
The time distribution is skewed right
The number of cars in the sample, n = 40 cars
The mean time spent at the window with the delivery system, [tex]\overline x[/tex] = 56.8 seconds
The Z-value for a mean time of 56.8 seconds is given as follows;
[tex]Z=\dfrac{\bar{x}-\mu }{\dfrac{\sigma }{\sqrt{n}}}[/tex]
Therefore, we get;
[tex]Z=\dfrac{56.8-59.3 }{\dfrac{13.1 }{\sqrt{40}}} \approx -1.20697620617[/tex]
Therefore, the z-value ≈ -1.21
From the normal probability table, we have;
P([tex]\overline X[/tex] ≤ 56.8) = P(Z < -1.21) = 0.11314
The probability of obtaining a sample mean of 56.8 second or less, assuming that the population mean is 59.3 seconds P([tex]\overline X[/tex] ≤ 56.8) = 0.11314.
