Answer:

125.6m^2

Step-by-step explanation:

Let R be the greater radius and r be the smaller radius

Area of the sidewalk = R^2 - r^2 - This can be the expression

= 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

= 40

= 3.14 x 40

Solve for x

A wall in a classroom has a length of 16 ft and a diagonal of 20 ft. A student is painting a rectangular mural on the wall. The mural has a length of 6 ft and a diagonal of 10 ft. What is the difference between the width of the wall and the width of the mural?
ill mark you brainliest pls help!
Answer choices:
A. 2ft
B. 4ft
C. 10ft
D. 14ft

Answers

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Answer is...B 4 ft....

Which measure of spread is the most appropriate for the data set represented by the graph?
A. range
B. quartiles
C. interquartile range
D. mean absolute deviation
E. either range or interquartile range

Answers

The answer is D! I hope this helps..

The most appropriate for the data set represented by the graph is mean absolute deviation.

What is Mean absolute deviation (MAD)?

It is a measure of variability or variation that indicates the average distance or average absolute distance between each data point or data value and the mean of a data set

We can calculate the variability of a data set by different measure thay include range, interquartile range, mean absolute deviation, standard deviation, etc.

Quartiles or ranges may be useful but they are limited as they tend to skip a lot of data in the group.

While, absolute deviation can help us get a more representative idea of spread for a data set like the one given in this question, where the elements have close difference.

Hence, the most appropriate for the data set represented by the graph is mean absolute deviation.

How is unit rate related to the linear equation?

Answers

Answer:

https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example

Step-by-step explanation:

Answer:

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.
