[tex] \frac{arc \ SR+arc \ TU}{2}=63 \\ \\ 55+arc \ TU=63*2 \\ \\55+arc \ TU=126\\\\ \ arc \ TU = 126-55=71^o[/tex]
Answer:
[tex]arc\ TU=71\°[/tex]
Step-by-step explanation:
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite
In this problem we have that
[tex]63\° =\frac{1}{2}(arc\ SR+arc\ TU)[/tex]
we have
[tex]arc\ SR=55\°[/tex]
substitute and solve for arc TU
[tex]63\° =\frac{1}{2}(55\°+arc\ TU)[/tex]
[tex]126\° =(55\°+arc\ TU)[/tex]
[tex]arc\ TU=126\°-55\°=71\°[/tex]

The table below shows the surface area y, in square inches, of a shrinking puddle in x hours: Time (x) (hours) 1 4 7 10 Surface area (y) (square inches) 100 85 70 55 Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and surface area of the puddle. [Choose the value of the correlation coefficient from −1, −0.99, −0.5, −0.02.] (4 points) Part B: What is the value of the slope of the graph of surface area versus time between 1 and 4 hours, and what does the slope represent? (3 points) Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)
Answers
Part A. The correlation coefficient, R², is the quantitative evaluation of how the data points are well-fitted to a model. The closer it is to 1, the better. But a R²=1 is very ideal and rare. This can be only true if the points coincides exactly with the given model. Since we can see in the graph that the points are exaclty passed through by the linear model, the correlation coefficient is 1.
Part B. The slope of the graph is measured between two points as Δy/Δx. So, between 1 to 4 hours, the slope is: (85-100)/(4-1) = -5. The slope represents the instantaneous rate of change of surface area with time. It is called instantaneous because the change was only between than interval, not the whole set of data. Also, the negative sign signifies that the trend is decreasing.
Part C. The data represents causation if the time was the cause of the change of the pond's surface area. However, this is not technically true because there might be other factors to be considered like environmental conditions. But, definitely, these data are in correlation because together they show an observable trend.

The minimum sustained wind speed of a Category 1 hurricane is 74 miles per hour. The maximum sustained wind speed is 95 miles per hour. Write an absolute value equation that represents the minimum and maximum speeds. Let v
represent the wind speed.
Answers
The absolute value equation that represents the minimum and maximum speeds of a Category 1 hurricane is |v - 84.5| ≤ 10.5, where v is the wind speed.
Explanation:To write an absolute value equation that represents the minimum and maximum speeds of a Category 1 hurricane, you will center it around the average of the two, which is (74 + 95) / 2 = 84.5 mph. The difference between the maximum speed and the average speed is 95 - 84.5 = 10.5 mph. Thus, the absolute value equation to represent the wind speeds of this hurricane category is |v - 84.5| ≤ 10.5, where v represents the wind speed.

#SPJ12
An absolute value equation representing the minimum and maximum sustained wind speeds of a Category 1 hurricane can be written as |v - 84.5| = 10.5, where v is the wind speed in miles per hour. This equation indicates that the wind speed can deviate by 10.5 mph above or below 84.5 mph, encompassing the range of 74 to 95 mph.
Explanation:To represent the minimum and maximum sustained wind speeds of a Category 1 hurricane using an absolute value equation, we can use the variable v to stand for the wind speed. The absolute value of a number represents its distance from zero regardless of direction, which in the context of wind speed means how much the speed differs from a certain value.
For instance, if the center value is the average of the minimum and maximum speeds, that would be (74 + 95) / 2 = 84.5 miles per hour. Therefore, the absolute value equation that represents the wind speeds that form the boundaries of Category 1 could be written as |v - 84.5| = 10.5. This equation means that the Category 1 wind speed, v, can be 10.5 miles per hour above or below 84.5 miles per hour, which corresponds to the range between 74 and 95 miles per hour.
However, there usually isn't just one single absolute value equation to represent this range. Another approach could involve setting two absolute value inequalities that represent the minimum and maximum separately, such as |v - 74| ≥ 0 for the minimum speed and |v - 95| ≤ 0 for the maximum speed.

The measure of arc UV is 24° .
What is arc?An “arc” is a smooth curve joining two endpoints. In general, an arc is one of the portions of a circle. It is basically a part of the circumference of a circle. Arc is a part of a curve.
According to the question
The Triangle formed inside the triangle
with angles 90° , 36° , ∠W
As sum of angle of triangle
99° + 36° + ∠W = 180°
∠W = 180° - 99° - 36°
∠W = 45°
Now,
According to the relation
∠W = [tex]\frac{1}{2}[/tex](arc SP - arc UV)
As
Arc SP = 94° + 20°
= 114°
so ,
45° = [tex]\frac{1}{2}[/tex]( 114° - arc UV)
90° = 114° - arc UV
arc UV = 114° - 90°
= 24°
Hence, the measure of arc UV is 24° .

A 125-inch pipe is cut into two pieces. one piece is four times the length of the other. find the lengths of the two pieces.
Answers
You can calculate the length of the two pieces of pipe by setting up and solving a simple equation: 'x' stands for the length of the shorter piece, '4x' stands for the length of the longer piece, which will add up to the total length, 125 inches. You will find that 'x' equals 25, meaning the shorter pipe is 25 inches long and the longer one is 100 inches long.
Explanation:This question revolves around a simple equation in algebra. If we say that the shorter piece of pipe's length is 'x', we know from the problem that the longer piece's length is four times this length, or '4x'. The total length of the pipe, 125 inches, is made up of these two pieces. Therefore, those two lengths must add up to 125 inches.
This gives us the equation 'x + 4x = 125'. Combining like terms gives us '5x = 125'. To find 'x', we then divide both sides of the equation by 5, giving us 'x = 25'. Therefore, the shorter piece of pipe is 25 inches long, and the longer piece, being four times this length, is 100 inches long.

In parallelogram ABCD, if angle C=110 and angle D=70, what is the sum of the measures of angle A and angle B?
Answers
To solve this problem, we must remember that the sum of interior angle of a polygon is:
Sum of interior angles = (n – 2) * 180˚
So, we can say that:
Sum of interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle D = 110 + 70 = 180˚
Therefore substituting this value:
angle A + angle B + 180˚ = 2 * 108˚
angle A + angle B = 360˚ - 180˚
angle A + angle B = 180˚ (answer)
Hence we can also conclude that,
angle A + angle B = angle C + angle D
The answer is 180 degrees because...
angle A + angle B + 180˚ = 2 * 108˚
angle A + angle B = 3
angle A + angle B = 180˚ 60˚ - 180˚

A

Answers
since A is a horizontal line it is constant
so A would be linear constant
By defining a constant line, we will see that the correct option is interval A.
What is a constant line?
A general linear equation is given by:
y = a*x + b
Where a is the slope and b is the y-intercept.
We say that a line is a constant line if the slope is equal to zero, so we get:
y = b
This would be graphed as a horizontal line.
So we only need to see which interval on the graph has a horizontal line. We will see that the interval is the A interval.

How many revolutions will a car wheel of diameter 26 in. make as the car travels a distance of one mile? (round your answer to the nearest whole number.)?
Answers

The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi
Answer:
776 revolutions per mile
Step-by-step explanation:
First we need to find the Circumference of the wheel.
Formula for circumference = πD
Where D = Diameter of the car wheel = 26 inches
Circumference of the car wheel = π × 26
= 81.68 inches
We have to find, how many inches make 1 mile.
1 mile = 63360 inches.
To determine the number of revolutions a car wheel of diameter 26 inches will travel,
= 63360 inches ÷ circumference of the car wheel
= 63360 inches ÷ 81.68inches
= 775.71 revolutions per mile
To the nearest whole number = 776 revolutions per mile.
