The diameter and radius of circle is 24.84 feet and 12.42 feet.

We are given the circumference of circle. So, using the formula of circumference, we will find the diameter. As we know, the radius of circle is half of its diameter.

Performing calculation now -

Circumference = π×d, where d stands for diameter of circle.

Taking the value of π as 3.14.

Keep the values in formula to find the diameter of circle

Diameter = 78÷3.14

Performing division

Diameter = 24.840

Rounding to nearest hundredth -

Diameter = 24.84 feet

Now, calculating radius by the formula -

Radius = diameter÷2

Radius = 24.84÷2

Performing division to find the radius of circle

Radius = 12.42 feet

Hence, the diameter and radius of circle is 24.84 feet and 12.42 feet.

Answer:

KN = 45, NM= 31, m<K = 61° m<L = 119°, m<M = 61°

Step-by-step explanation:

Given: KL = 31 LM = 45 N = 119°

This is a parallelogram so sides will equal.

KL = NM (31) LM = KN (45)

The inside of a parallelogram equals 360°. Opposite angles are congruent.

L = N (119°) So, 119 + 119 = 238

360 - 238 = 122

122 ÷ 2 = 61°

So, K = 61° M = 61° L = 119°

The average of the last three numbers is 58 if the average of the five numbers in a list is 54. the average of the first two numbers is 48.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

It is given that:

The average of the five numbers in a list is 54. and the average of the first two numbers is 48.

54 = sum of the five numbers/5

54x5 = sum of the five numbers

270 = sum of the five numbers

48 = sum of the two numbers/2

48x2 = sum of the two numbers

96 = sum of the two numbers

Sum of three numbers = 270 - 96

Sum of three numbers = 174

The average of the last three numbers = 174/3 = 58

Thus, the average of the last three numbers is 58 if the average of the five numbers in a list is 54. the average of the first two numbers is 48.

Answer: 100 $

Step-by-step explanation:

300 divided by 3 is 100

The equation in slope-intercept form is y = -2/3x + 6

Given,

Points (x, y) = (6, 2)

Parallel to y = -2/3x + 1

Now,

Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "-2/3" (the coefficient that accompanies "x").

Therefore the equation of a parallel line has to be of the form:

y = -2/3x + b

2 = -2/3(6) + b

2 = -12/3 + b

2 = -4 + b

b = 6

The local gym holds three 45-minute workout sessions and two 30-minute sessions each week. Then the, total number of minutes Judy worked out for the week was 155 minutes.

We are to determine the total number of minutes Judy worked out for the week.

The gym holds three 45-minute workout sessions and two 30-minute sessions each week

So,

We can write,

The total number of minutes the gym holds workout sessions is

3 × 45 + 2 × 30

= 135 + 60

= 195 minutes

Also, from the information,

Judy left 5 minutes early during the 30-minute sessions and 10 minutes early during the 45-minute sessions.

The total number of minutes Judy didn't attend is

= 3 × 10 + 2 × 5

= 30 + 10

= 40 minutes

Then,

The total number of minutes Judy worked out for the week was,

= 195 minutes - 40 minutes

= 155 minutes

Therefore,

The total number of minutes Judy worked out for the week was 155 minutes.

B. The percentage of standardized test scores that is less than 210 or greater than 840 is 0.3%.

C. The percentage of standardized test scores that is greater than 735 is 2.2%.

a) The z score for 210 will be:

Using translation concepts, the new coordinates of the point are given as follows:

(-2.5, 9.8).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

For this problem, the translation rule for each point is given as follows:

(x, y) → (x - 7.5, y + 6.8)

This translation rule means that the figure is shifted:

The original coordinate is given by:

The simplication of the given expression is (3x - 8) /4x² and the restriction on the variable in the denominator of the given expression is x ≠ 0.

According to the given question.

We have an expression 3/4x - 2/x^2

Since, we have to simplify the above expression.

Therefore,

3/4x - 2/x²

⇒ (3x - 8) /4x²

Hence, the simplication of the given expression is (3x - 8) /4x².

Also, we have to find the restriction on variable.

As we know that, we never divide by 0, a restriction on the variable of a rational function with a linear denominator would be any value of the variable that makes the linear denominator equals to 0.

So, for the restriction on the variable.

Set the denominator equals to 0.

⇒ 4x² = 0

Solve for x

x = 0 ( because 4 ≠ 0)

The denominator is 0 when x = 0. This is the only value that makes the given expression undefined.

Therefore, the restriction on the variable in the denominator of the given expression is x ≠ 0.

The following set of numbers, 20, 21 and 31, can be the measures of the sides of an obtuse triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 20, b = 21, and c = 31

a + b > c     20 + 21 > 31     41 > 31     True

a + c > b     20 + 31 > 21     51 > 21     True

b + c > a     21 + 31 > 21     52 > 20     True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

20^2 + 21^2 = 841

2. Compare it to the square of the largest side.

31^2 = 961

961 > 841

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

The probability of hitting the area of the shaded region is 0.21 (in the form of two decimal places) when you throw a dar.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that the radius of the circle = 2cm

So one side of square = 2+2 = 4cm

Area of circle = πr² = (3.14) ×(2)²= (3.14)×4 = 12.57cm²

Area of square = (a)² = (4)² =16cm²

Then the area of the shaded region = 16−12.57 = 3.43cm²

So the probability of hits in the shaded region = 3.43/16 = 0.2144

Round to the nearest Hundredth (two decimal places).

The probability of hits in the shaded region = 0.21

The magnitude of the vector JK is estimated to be  2√13.

The given vector JK's direction is - Ф = 33.69° (angle lies in the fourth quadrant with having direction in clockwise)

The algebraic demonstration of the coordinate-based distances between two points (in coordinate system). Using rectangular coordinates, the Pythagorean theorem is employed to determine distances among points in 2- and 3-dimensional Euclidean space.

Now, in answer to your questioning;

J and K have coordinates of (8,1) & (2,5), respectively.

The following is the distance formula for the points J & K:

JK² = (x₂ - x₁)² + (y₂ - y₁)²

JK = √[(x₂ - x₁)² + (y₂ - y₁)²]

The given of coordinates of J and K's  are-

(x₁,y₁) = (8,1)   and (x₂,y₂) = (2,5).

Substituting the given values in the distance formula;

JK = √[(2 - 8)² + (5 - 1)²]

JK = √[(-6)² + (4)²]

JK = √[36 + 16] = √52

JK  = 2√13 (magnitude of the vector JK)

Now, estimate the vector JK's direction.

The angle formed by a vector with a horizontal line defines its direction.

Use one of the given equation to find the direction of a vector.

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

        = (5 - 1)/(2 - 8)

tan Ф = 4/(-6) = -2/3

Ф = 33.69° (angle lies in the fourth quadrant with having direction in clockwise)

As a result, the distance between J and K is found to be 2√13, that is the same as a magnitude of the given vector JK.
