how to find the circumference with a radius​

Answers

Answer 1

Answer:

The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.

Answer 2

Answer:

the circumference is pi*diameter. diameter is radius*2, and so (radius*2)*pi is the circumference

Find the inequality represented by the graph in the picture


(Khan academy)

Answers

Answer:

[tex]y < 3x - 4[/tex]

Step-by-step explanation:

We can tell right away, that the line has a positive slope, since it goes upwards and to the right. To find the slope exactly, we will use rise/run. We will count the units from the first given point until we reach the next point.

So we can tell that the slope is 3/1 or just 3.

Also, since the line crosses the y-axis at -4, this will be the y-intercept.

Next, since the line is dotted, we know that the inequality sign will either be the "greater than" sign, or the "lesser than" sign. In this case, since the shaded area is below the line, we will use the "lesser than" sign.

So all together, we have y < 3x - 4.

Hope this helps you :)

He has a new 0.85-ounce tube of toothpaste that’s supposed to last him the whole trip. The amount of toothpaste Ken squeezes out of the tube each time he brushes varies according to a Normal distribution with mean 0.13 ounces and standard deviation 0.02 ounces.

Answers

Using the normal distribution, it is found that there is a 0.8888 = 88.88% probability that his tube last the whole trip.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. For n instances of a normal variable, the mean is [tex]n\mu[/tex] and the standard deviation is [tex]s = \sigma\sqrt{n}[/tex]

In this problem:

For each time he brushes his teeth, the mean is of 0.13 ounces and the standard deviation is of 0.02 ounces, hence [tex]\mu = 0.13, \sigma = 0.2[/tex]He will brush his teeth 6 times, hence [tex]n = 6, n\mu = 6(0.13) = 0.79, s = 0.2\sqrt{6}[/tex]

The probability that his tube last the whole trip is the p-value of Z when X = 0.85, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Considering the n instances

[tex]Z = \frac{X - n\mu}{s}[/tex]

[tex]Z = \frac{0.85 - 0.79}{0.2\sqrt{6}}[/tex]

[tex]Z = 1.22[/tex]

[tex]Z = 1.22[/tex] has a p-value of 0.8888.

0.8888 = 88.88% probability that his tube last the whole trip.

Logan is a great babysitter. He makes $9 an hour. Jeanette is an even better babysitter. She makes $16 an hour. Jeanette works 18 hours each week. How many
hours does Logan need to work in order to earn as much money as Jeanette earns in a week?

Answers

Answer:

18hx16money=288 dollars

Step-by-step explanation:

to ez and np

Answer:

32 hours a week

Step-by-step explanation:

First you have to find out how much Jeanette makes. You can do this by multiplying 16 x 18 since she makes $16 18 times a week. This gives you $288 that she makes each week.

Now to find how much Logan would have to work you take 288 and divide it by 9. You do this because you need to see how many times 9 goes into 288 to give you the amount of hours. When you divide you get 32.

The following dataset represents the number of minutes a student listens to music in a week for 50 students, sorted and
arranged in rows of 5. What is the 80th percentile of the data?

Answers

Using the percentile relation, the 80th percentile of the data is 77.

The 80th percentile of a data can be defined as :

80th percentile = 80% × (n+1)th term n = sample size = 50

Hence, we have ;

80th percentile = 0.8 × (50 + 1)th term

80th percentile = 40.8 term = 41th term

Since, the days is sorted, the 80th percentile is the value at index 41.

Hence, the 80th percentile of the data is 77.

Answer:

I = $650

A = $23,580

Step-by-step explanation:

First question

I = ?, P = $1000, R= 5%, T = 13

[tex]I = \frac{P*R*T}{100}=\frac{1000*5*13}{100}= 650[/tex]

Therefore, interest = $650

Second...

P = $15, 000, R = 5.2%, T = 11, I = ? A= ?

[tex]I = \frac{P*R*T}{100}=\frac{15000*5.2*11}{100}= 8580[/tex]

To find A, we add the principal with the interest

A = P + I = $15,000 + $8580 = $23,580

"A Dog's Mistake"by Andrew Barton PatersonHe had drifted in among us as a straw drifts with the tide, He was just a wand'ring mongrel from the weary world outside; He was not aristocratic, being mostly ribs and hair, With a hint of spaniel parents and a touch of native bear.He was very poor and humble and content with what he got, So we fed him bones and biscuits, till he heartened up a lot; Then he growled and grew aggressive, treating orders with disdain, Till at last he bit the butcher, which would argue want of brain.Now the butcher, noble fellow, was a sport beyond belief, And instead of bringing actions he brought half a shin of beef, Which he handed on to Fido, who received it as a right And removed it to the garden, where he buried it at night.Twas the means of his undoing, for my wife, who'd stood his friend, To adopt a slang expression, "went in off the deepest end," For among the pinks and pansies, the gloxinias and the gorse He had made an excavation like a graveyard for a horse.Then we held a consultation which decided on his fate: Twas in anger more than sorrow that we led him to the gate, And we handed him the beef-bone as provision for the day, Then we opened wide the portal and we told him, "On your way."Question #1Based on the first stanza, what can the reader infer about the dog?He was a bit aggressive towards those in his environment.He moved as if he was exhausted and unsure where to go.He was smart enough to find food on his own.He had no manners because he had not been around people.Question #2Which three lines from the poem support the inference that the dog becomes unappreciative of the help he is receiving?"He was very poor and humble and content with what he got," (line 5)"Then he growled and grew aggressive, treating orders with disdain," (line 7)"Till at last he bit the butcher, which would argue want of brain."
