50.24

Step-by-step explanation:

8÷2 is the radius. 3.14×4^2=50.24 m^2

^= where the exponent is supposed to go

Find the area and the circumference of a circle with diameter 8 m .

1)

[tex] \pink{\boxed{ \sf{Area \: of \: circle = \pi r {}^{2} }}}[/tex]

2)

[tex] \pink{\boxed{\sf{Circumference of circle = 2\pi r}}}[/tex]

We know that radius of circle is always halves of its diameter . So radius of circle :

1) Finding area :

Therefore, area of circle is 50.24 m² .

2) Finding circumference :

Therefore, circumference of circle is 25.02 m

Answer:

22) a. Supplemental angles

      b. 43.5 degrees and 136.5 degrees

Step-by-step explanation:

22) a) If 2 angles are on a straight line then they are supplemental angles.  Supplemental angles add up to 180 degrees

b) (x+1) + (3x+9) = 180

Combine like terms

4x + 10 = 180

4x = 170

divide both sides by 4

x = 42.5

so the 2 angles are 1) 42.5 + 1 = 43.5 and 2) 3(42.5) + 9= 136.5

P(teacher and chooses play) is an example of independent events.

What is Independent events?

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B.

According to questions, the activity preference of teachers and librarians

are:

For Teachers:

Movies 3

Books 4

Plays 2

For Librarians:

Movies 12

Books 9

Plays 15

Since, Teacher and Plays both are independent events, they are not related to each other.

So, we can conclude that P(teacher and chooses play) is an example of independent events.

Answer: The middle number in a data set when the data are put in order.

Answer and Step-by-step explanation:

To find the median of a set of numbers, you need to find what the number in the center is in a listed group of numbers. I'll use the example of these numbers:

6, 9, 5, 4, 3, 4, 2.5, 8, 0, 1, 5.

First, we need to organize the numbers in numerical order to find the median.

0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.

It would be the most simple and helpful to cross out each number until we get our center number; the median. (I can't cross the numbers out, so I'll underline them instead.) When crossing out, both sides need to be full of equally crossed out numbers.

0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.

The number in the center for this example problem is 4. Thus meaning that our median is 4.

Sometimes though, it is not always a whole number. Sometimes you'll have to find the median in between two numbers. For example, let's just say you got stuck between 4 and 5. Then the median for that set of data would be 4.5, because it is still in the middle of the two.

I hope that this helps, let me know if you have any more questions about this topic.

The intensity of the earthquake is an illustration of functions

The function is given as:

[tex]M=0.67 \log(0.37E)+1.46[/tex]

When the earthquake releases 10,500,000,000, we have:

[tex]M=0.67 \log(0.37*10500000000)+1.46[/tex]

Evaluate

[tex]M=7.8848919855[/tex]

Approximate

[tex]M=7.88[/tex]

Hence, the earthquake's magnitude is 7.88

Also, we have:

Earthquake 1 = 6.2

Earthquake 2 = 5.3

Calculate the difference (d)

[tex]d = 6.2-5.3[/tex]

[tex]d = 0.9[/tex]

Hence, the earthquake is 0.9 times more than the earthquake that measured 5.3

Answer:

620 miles

Step-by-step explanation:

knowing that if his parents drive 155 miles to camp and then go back and then pick him up in two weeks.

Thus ,Times they drove back and forth is:

Drive to camp

Go back home

Pick him up

Drive back home

Hence, that a total of 4.

Since it 155 miles to camp then it the same going back home and pick him up and then drive back home

Therefore,

155 × 4 =   620

As a result, they would have to traveled 620 miles.

The matrix shown represents its elements in rows and columns

The operation performed by the student is R3 -> 2R2 + R3.

The matrix is given as:

[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&2&4&5\end{array}\right][/tex]

Multiply the elements on the second row (Row 2) by 2.

So, we have:

2R2 = 0 -2 6 2

Add these elements to the third row (Row 3).

So, we  have:

2R2 + R3 = 3 0 10 7

Replace the row 3 by the above elements.

i.e.

R3 -> 2R2 + R3.

So, we have:

[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&0&10&7\end{array}\right][/tex]

Hence, the operation performed by the student is R3 -> 2R2 + R3.

Because we now know that he earns 5.8 per hour we can just do 135/5.8 (23.28) < this is rounding to the nearest hundreth

to get the equation of any straight line we only need two points off of it.

1st one

well, we have four points on the table, let's use a couple from it hmmm say (10 , -25) and (13 , -34)

[tex](\stackrel{x_1}{10}~,~\stackrel{y_1}{-25})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-34}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-34}-\stackrel{y1}{(-25)}}}{\underset{run} {\underset{x_2}{13}-\underset{x_1}{10}}}\implies \cfrac{-34+25}{3}\implies \cfrac{-9}{3}\implies -3[/tex]

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-25)}=\stackrel{m}{-3}(x-\stackrel{x_1}{10}) \\\\\\ y+25=-3x+30\implies y=-3x+5[/tex]

4th one

well, from the picture itself we already have a couple of points we can use hmmm (0 , -4) and (5 , 0)

[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{0}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{0}-\stackrel{y1}{(-4)}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{0}}}\implies \cfrac{0+4}{5}\implies \cfrac{4}{5}[/tex]
