Graphs of the following equations are straight lines except :

The two circles shown above have radii of 8 in. and 4 in. What is the Circumference of the both?

Dmitry [639]

Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches

Step-by-step explanation:

Radius of circle 1 = 8 inches

Radius of circle 2 = 4 inches

We need to find circumference of both circles.

The formula used to find the value of circumference is:

$Circumference=2\pi r$

Finding Circumference of Circle 1:

Radius = 8 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*8$

$Circumference=50.24\,\,inches$

Finding Circumference of Circle 2:

Radius = 4 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*4$

$Circumference=25.12\,\,inches$

So, Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches

According to an informal poll in Glenview 1/3

Talja [164]

Answer:

Percent form: 41.65%

Fraction form: $\frac{833}{2000}$

Step-by-step explanation:

33% of men support John Smith.

67% of women support John Smith.

Lets say, for instance, that there are 20 polled individuals -- 10 women and 10 men.

However, since 1.5 times as many men voted as women, we have to apply our poll to 15 men and 5 women.

33% of the 15 men makes 5 men who voted for Smith and 10 who did not.

67% of the 5 women makes 3.33 women who voted for Smith and 1.67 who did not.

Add these numbers together.

8.33 total voters were cast for John Smith, while 11.67 were not.

Now, divide 8.33 by 20 and multiply by 100 to obtain a percentage.

$\frac{8.33}{20} \\.4165\\41.65$

41.65% of voters voted for John Smith according to the results of the poll.

$2680

Step-by-step explanation:

3.00-1.50= 1.50 profit per hotdog

1200+800=2000 expenses

1.50 (3120) = 4680

4680-2000=

The researcher also determined that the standard deviation of all horses coming to the veterinary clinic is 8 years. Based on th

elena-14-01-66 [18.8K]

Answer: 0.9013

Step-by-step explanation:

Given mean, u = 10, standard deviation =8

P(X) =P(Z= X - u /S)

We are to find P(X> or =12)

P(X> or = 12) = P(Z> 12-10/8)

P(Z>=2/8) = P(Z >=0.25)

P(Z) = 1 - P(Z<= 0.25)

We read off Z= 0.25 from the normal distribution table

P(Z) = 1 - 0.0987 = 0.9013

Therefore P(X> or=12) = 0.9013

Note the question was given as an incomplete question the correct and complete question had to be searched online via Google. So the data used are those gotten from the online the Googled question.

leons older brother is 4and 3/4 feet tall. Leon is 1/3 foot shorter than his brother. How tall is leon

S_A_V [24]

Answer: $4\frac{5}{12}\ feet$

Step-by-step explanation:

The height of Leon's older brother = $4\frac{3}{4}$ feet

$=\frac{16+3}{4}=\frac{19}{4}$ feet

Since, Leon is 1/3 foot shorter than his brother.

Then, the height of Leon = $\frac{19}{4}-\frac{1}{3}$

First we need to make them like fractions by multiplying 3 on the numerator and denominator of the first fraction and 4 on the numerator and denominator of the second fraction.

Then, the height of Leon = $\frac{57}{12}-\frac{4}{12}$

$=\frac{57-4}{12}\\=\frac{53}{12}=4\frac{5}{12}$ feet

Hence, The height of Leon = $4\frac{5}{12}\ feet$
