What Is The Circumference Of The Circle?

Answers

Answer 1

Answer:

[tex]\huge\boxed{\bf\:E) \: \: 31.4 \: \:feet}[/tex]

Step-by-step explanation:

Since the tetherball is in the centre of the circle, any distance from it to the edge of the circle will be its radius. So, radius (r) = 5 ft.

Now, the formula for the cirumference of a circle = 2πr

Circumference of the circle

= 2πr

= 2 × 3.14 × 5                      [π = 3.14]

= 31.4 feet (option E)

          What is the circumference of the circle? (Its radius is 5 ft)

[tex]\diamond\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond[/tex]

The distance from the tetherball pole to the edge of the circle is the radius of the circle; we're given that it's 5 feet (ft).

We're asked to find the circumference of the circle, which can be found using the following formula:-

❖  [tex]\sf{C=2\pi r}[/tex]

Where:-

C=circumferenceπ=pi (3.14...)r=radius

Substitute 5 for r:-

[tex]\sf{C=2\pi (5)}[/tex]

On simplification,

[tex]\sf{C=10\pi}[/tex]

On further simplification,

[tex]\sf{C=31.4\:feet}[/tex]

So we conclude that the right option is:-

[tex]\checkmark\dashrightarrow\bigstar\boxed{\boxed{\bold{Option\:E}}}\bigstar\dashleftarrow\checkmark[/tex]

Good luck.

Is the vertex of the graph a maximum or a minimum?

Answers

Answer:

maximum

Step-by-step explanation:

Concepts

The vertex of a graph represents the turning point in a parabola.

Example: The graph shown in your question first steadily increases, but then at the point (1,3), it begins to go down. The point (1,3) is called the vertex in this case because it symbolizes the turning point.

Application

We are asked to determine if the vertex of this graph is a maximum or minimum. If the vertex is maximum, it's the highest point on the graph. If it's the minimum, it's the lowest point on the graph. Using your stunning eyes, you can see that the vertex is the highest point on the graph, making the answer maximum.

The midpoint of overline AB is M(-4, 0)M If the coordinates of A are (-6, 6) what are the coordinates of B?

$125 per hour in addition to $55 for an assistant. The committee
wants to keep the total cost under $600. Which inequality represents
the maximum amount of hours the DJ will play at the dance?

Answers

Answer: 4 hours

Step-by-step explanation:

4 Hours

Explanation:

Make h = hours

You add the $55 extra cost for the assistant

$125h + $55 = $555

Use additive inverse to isolate the term with the variable

$125h + $55 - $55 = $555 - $55

Use multiplicative inverse to isolate the variable

[tex]\frac{125h}{125}[/tex] = [tex]\frac{500}{125}[/tex]

Hours would be: 4 Hours.

51% of a university's freshman class are majoring in Economics. If 4590 students in the freshman class are Economics majors, how many students are in the freshman class?

Answers

Answer:

2340

Step-by-step explanation:

4590*.51=2340.9

Because you can not have .9 people, you round down to 2340

2341 students are in the freshman class.

What is percentage?

Percentage is defined as ratio expressed as a fraction of 100.

Total no. of students in the freshman Economics majors = 4590

51% students of a university's freshman class,

Let x no. of students in the freshman class,

x = 51/100×(4590)

The area of a rectangle is 49d + 91
The length is an integer higher than 1, but is a known number.
Find the width of the rectangle.

Answers

Assuming that L and d are known numbers, we can write.

[tex]W = \frac{49d + 91}{L}[/tex]

How to get the width of the rectangle?

Remember that for a rectangle of width W and length L, the area is given by:

A = L*W

In this case, the area is 49d + 91, and the length is a known number, so we know the value of L.

Then we can write:

A = L*W =  49d + 91

To get the value of W, we need to isolate it on one side of the equation.

We can do that by dividing both sides by L.

[tex]W = \frac{49d + 91}{L}[/tex]

We assume that d and L are known, so with the above rational expression, we have W totally determined.

No, corresponding angles aren't congruent

Step-by-step explanation:

We have a transversal and lines intersecting with it.

The angle measures formed by the lines and the transversal are not all equal to each other.

Four of the angles measure 85° and one 79°.

These are corresponding angles (the angles which occupy the same relative position at each intersection where a straight line, transversal,  crosses two or more others).

If corresponding angles are equal, the lines are parallel.

In our case all the lines intersecting the transversal are parallel apart from the one with different angle measure.

Therefore, correct answer choice is:

A the time left until the pool is empty

B the gallons of water initially in the pool
Cthe total hours required to drain the pool
D the amount of water being drained per hour

Answers

Using linear function concepts, it is found that the representation of the value of 4,000 is given by:

B the gallons of water initially in the pool.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, the amount of water in the pool after x hours is modeled by:

y = -720 x + 4000.

4000 is the y-intercept, which is the initial amount of water in the pool, hence option B is correct.
