Answer:
Length= 50
Width=17
Step-by-step explanation:
length= n+8
Since n= 42, Just plug it in. So it would be 42+8 which is 50 for the length
Widith: 1/2n-4
basically since N is given for 42, you do 1/2 multipied by 42 which is 21.
Since you also have to subtract 4 inches it would be 17 for the length
What is value of x? enter your answer in the box. X = a triangle with vertices labeled as a, b, and c. Side b c is the base. A line segment is drawn from vertex a to base b c that bisects angle b a c into two parts marked with single arcs. Side a b is labeled as 8. Side a c is labeled as 12. Side b c is divided into two equal parts labeled as x plus 4 and 2 x plus 1.
The value of x calculated by using the Pythagorean theorem is equal to 6.
This can be found by using the Pythagorean theorem to solve for the length of side bc, which is the base of the triangle. By using the two given side lengths of 8 and 12, we can find that the length of the hypotenuse (bc) is equal to the square root of 8^2 + 12^2, which is equal to 16.
Since the base is divided into two equal parts, we can divide 16 by 2 and get 8. We then subtract the given length of 2x + 1 from 8 and get 7, which means x is equal to 6.

The table shows the length and width of proportional rectangles. Length (in inches) 4 6 12 16 width (in inches) 10 15 30 40 using the table, find the width of a rectangle that has a length of 24.
The width of a rectangle that has a length of 24 inches would be 60 inches.
According to the data, we can assume that all the rectangles in the table have the same ratio of measurement.
To find unknown width of the rectangle, we can use this equation:
A/B = C/D
Where:
A represents the length of the first rectangle
B represents the width of the first rectangle
C represents the length of the second rectangle
D represents the width of the second rectangle
In this case, we are going to use 12 as the length of the first rectangle, and 30 as its width.
12/30 = 24/D
12D = (30 x 24)
12D = 720
D = 60
Thus, the width of the rectangle that has a length of 24 inches is 60 inches.

Sophie would have $15,786 more than Sydney.
What is the compound interest?We know that the compound interest has to do with the kind of interest that we have to compound but on the principal and the the interest. In this case, we can see that we have;
A = P(1 + r/n)^nt
A = amount

A tunnel is constructed with a semielliptical arch. The width of the tunnel is 70 feet, and the maximum height at the center of the tunnel is 20 feet. What is the height of the tunnel 10 feet from the edge? round your answer to the hundredths place.
Considering the equation of an ellipse, it is found that the height of the tunnel 10 feet from the edge is of 14 feet.
The following is the equation for a horizontal ellipse of center with coordinates (h,k):
(x - h)²/a² + (y - k)²/b² = 1.
In relation to this issue, we have that:
The origin is where the center is.
Since the major axis is 70, 2a = 70 and a = 35.
The maximum height is 20, therefore b is equal to 20.
As a result, the ellipse's equation is as follows:
x²/35² + y²/20² = 1.
It is determined that x = 25 when the tunnel is 10 feet from the edge since 35 – 10 = 25; therefore, the height y is calculated as follows:
25²/35² + y²/20² = 1
0.51 + y²/20² = 1
y²/20² = 0.49
y² = 20² x 0.49
y =√(20² x 0.49)
y = 14 feet.

What is parabola?
A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
In general, if the directrix is parallel to the y-axis in the standard equation of a parabola is given as:

0.9 -0.3
0.5 -0.8
Answer: The correlation coefficient (also known as Pearson's correlation coefficient or r) is a measure of the strength of the linear relationship between two variables. The value of the correlation coefficient ranges between -1 and 1, with a value of 1 indicating a perfect positive linear relationship, a value of -1 indicating a perfect negative linear relationship, and a value of 0 indicating no linear relationship.
In this case, the correlation coefficient that represents the strongest linear relationship is
0.9
The absolute value of the correlation coefficient measures the strength of the linear relationship, regardless of whether it is positive or negative. So, the absolute value of 0.9 and -0.3 are both 0.9. but as we are looking for the strongest linear relationship, the value of 0.9 is closer to 1 than -0.3 is and it indicates stronger positive relationship.
In summary, the closer the correlation coefficient is to 1 or -1, the stronger the linear relationship between the variables is. In this case, 0.9 has the strongest linear relationship of the given options.

y=
Answer:
For each service call cost of 20$ will be added to fixed cost of 3000$.
Step-by-step explanation:
The total cost for 1 month is the sum of the fixed monthly cost and the cost of all the service calls, so we can write the equation as:
y = 3000 + 20x
This equation is already in slope-intercept form, where "y" is the dependent variable, "x" is the independent variable, 3000 is the y-intercept (the point where the line crosses the y-axis, when x=0), and 20 is the slope of the line.
This equation can be interpreted as

What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points (8, 12800) and (14, 14420)
So, the slope is
= (14420 - 12800)/(14-8)
= 1620/6
= 270
and, the slope intercept form
(y - 12800) = 270 (x - 8)
y- 12800 = 270 x - 2160
y = 270x + 10640
