Given the internal radius of the pipe is 2 cm, the external radius is 2.4 cm and the length of the pipe is 10 cm. Find the total surface area of the pipe.

Answer:

(0, 3)

Step-by-step explanation:

Visualize this problem as being based on a circle of radius 3.  (-3, 0) lies on this circle, straddling the x-axis.

Now if we rotate that radius (connecting the (0, 0) to (-3, 0) clockwise, the point (-3, 0) becomes the point (0, 3).

Answer:

A. 103.96

B. 93.5

C. 43.5

D. 112

103.96, 112, 93.5, 43.5

Answer: The y-intercept affects where the linear equation meet the y-axis. The slope affects how steep the linear equation is on the graph.

Answer: About 24 miles per hour or 11 meters per second.

Step-by-step explanation: It's concluded that the airspeed velocity of an unladen swallow is about 24 miles per hour or 11 meters per second.

The airspeed velocity of a unladen swallow is about :

24 miles/hr or 11 m/s

In aviation, airspeed is the speed of an aircraft relative to the air.

Given is to answer the speed of a unladen swallow.

The airspeed velocity of a (European) unladen swallow is about :

24 miles/hr or 11 m/s.

Therefore, the airspeed velocity of a unladen swallow is about :

24 miles/hr or 11 m/s.

Answer:

5 ft and 11 ft

Step-by-step explanation:

l= 2w+1

A=lw= 55

w(2w+1)=55

2w²+w-55=0

integer solution of quadratic equation is:

w=5 ft

l= 2*5+1=11 ft

Answer:

32 feet

Step-by-step explanation:

Start by creating your 2 equations

l = 2w + 1

l * w = 55

Plug in l, the isolated variable

(1 + 2w)w = 55

w + 2w² = 55

2w² + w -55 = 0

( − 5 ) ( 2 + 1 1 ) = 0

w= 5

w= -11/2 <- the width can't be negative so this one is out

Plug width into the area formula to find length

l * 5 = 55

l = 11

Find the Perimeter

2(11) + 2(5)

22 + 10 = 32

The statement which is true for the function having slope is that the function is linear.

Function is like a defined relationship between two or more variables expressed in equal to form. In a function each value of x must has a corresponding y value. The value which is entered in the function is known as domain and the value which comes out after is codomain of the function.

We have been given that slope of function is -3.

1) The function is linear because slope is in single number.

2) We cannot say that the equation is y=-3x because it depends on other points also. Suppose the point at which the line passes is (1,2)

y-2=-3(x-1)

y-2=-3x+3

y=-3x+3+2

y=-3x+5

So  this statement is wrong,

3) Same in statement third , we cannot say that the point (2,-6) lie on line.

4) It is wrong because in the given option slope is -1/3.

Hence the correct statement is that the function is linear.

Answer:

The cost of 1 calculator is $28.00

Step-by-step explanation:

You haven't mentioned the question. Anyways if you want to find the value of 1 calculator, the simplest method ( in my opinion) you could do so in the ratio method:

 5 calculators : $140

 1 calculators : x

( x is the cost of 1 calculator. You have to find x. )  

Cross multiply both the ratios. Multiply 5 with x and 140 with 1.

5x = 140 × 1

5x = 140

Bring 5 to the other makes 140 divided upon 5, as it was multiplied with x.

x = [tex]\frac{140}{5}[/tex]

x = $28

You could not only find the cost of 1 calculator, but any number of calculators. Just replace the number of calculators with 1 calculator that I have found the cost of.

     14 :  21                                                                             25 : 35

Mrs Washington has a greater ratio of band students to chorus students.  I know my answer is correct because I compared the ratio of the band to chorus students where the Band was the same. When Band to chorus had 10:15  students for Washington's class, and Band to chorus had 10:14 in Utley's class. This means That Washington had more students.

Answer:

1. the company C used 10 drivers2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  (6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/103. The groups that had the most deliveries where group A and B4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

Step-by-step explanation:

The mean absolute deviation of company C's data is 2.

A dot plot, also known as a strip plot or dot chart, is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis. These types of charts are used to graphically depict certain data trends or groupings.

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

We are given the sum of each point from the mean. It is 20.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4×2 = 4 times MAD (since MAD =2 for both companies).

Therefore, the mean absolute deviation of company C's data is 2.
