Answer:

(5x + 8y)(5x - 8y)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = (a + b)(a - b) where a = 5x and b = 8y.

Answer:

Triangles are not similar.

Step-by-step explanation:

Properties of the similarity of two triangles,

1). Corresponding angles of two triangles are equal in measure.

2). Corresponding sides of the similar triangles are proportional.

From the given triangles,

- Corresponding angles of the given triangles are not equal in measure.

- Ratios of the corresponding sides,

 [tex]\frac{KM}{XY}=\frac{CM}{RY}= \frac{KC}{XR}[/tex]

[tex]\frac{53}{53}= \frac{54}{53}= \frac{64}{53}[/tex]

But these ratios are not equal.

Therefore, both the triangles are not similar.

Answer:

x + 2y - 3 = 0

Step-by-step explanation:

Coordinates of the points P and Q are (-3, 0) and (0, 6) respectively.

Slope of PQ = (0- 6)/(-3 - 0) = - 6/-3 = 2

Slope of line perpendicular to PQ = - 1/2

Since, required line passes through point R(7, - 2) and is perpendicular to PQ.

Therefore, equation of line in point slope form is given as:

[tex]y - (-2) = - \frac{1}{2} (x - 7) \\ \\ y + 2 = - \frac{1}{2} (x - 7) \\ \\2(y + 2) = - (x - 7) \\ \\ 2y + 4 = - x + 7 \\ \\ 2y + 4 + x - 7 = 0 \\ \\ x + 2y - 3 = 0[/tex]

Therefore x + 2y - 3 = 0 is the required equation of line.

Answer:

Answer:

x + 2y - 3 = 0

Step-by-step explanation:

Coordinates of the points P and Q are (-3, 0) and (0, 6) respectively.

Slope of PQ = (0- 6)/(-3 - 0) = - 6/-3 = 2

Slope of line perpendicular to PQ = - 1/2

Since, required line passes through point R(7, - 2) and is perpendicular to PQ.

Therefore, equation of line in point slope form is given as:

\begin{gathered}y - (-2) = - \frac{1}{2} (x - 7) \\ \\ y + 2 = - \frac{1}{2} (x - 7) \\ \\2(y + 2) = - (x - 7) \\ \\ 2y + 4 = - x + 7 \\ \\ 2y + 4 + x - 7 = 0 \\ \\ x + 2y - 3 = 0\end{gathered}

Answer:

yeah whats the question asking >:(

Answer:

20°

Step-by-step explanation:

In circle with center O, PS is diameter.

[tex] m\angle PRS =90\degree [/tex]

(angle inscribed in semicircle)

PQRS is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

[tex] \therefore m\angle QPS + m\angle QRS = 180\degree [/tex]

[tex] \therefore (x\degree +25\degree) +(45\degree +90\degree) = 180\degree [/tex]

[tex] \therefore x\degree +25\degree + 45\degree +90\degree = 180\degree [/tex]

[tex] \therefore x\degree +160\degree = 180\degree [/tex]

[tex] \therefore x\degree = 180\degree-160\degree [/tex]

Answer:

V=634.0 cubic meter.

Step-by-step explanation:

By formula   V=πr^2(h/3)

so  V=π5.8^2(18/3)

then 5.8square2 =33.64 ,18/3=6  and pi  

multiply everything you'll get  V=634.0990612

finally it says round to the nearest tenth which mean , V=634.0 cubic meter.

Answer:Percentage of students who prefer scary movies =35%

Step-by-step explanation:

Number of students who prefer scary movies= 35

Number  of students who love comedies= 65

Total number of students = 65 +35= 100

Percentage of students who prefer scary movies = Number students who prefer scary movies/ total number of students x 100

35/ 100 x 100

0.35 x 100= 35%

PART A:

To find the rate of change, put change in y over change in x. In order to first find the changes, you must subtract two y values from each other and two x values from each other, like this:

Change in y = 20-10

Change in x = 4-2

Then you can put these over each other:

20-10/4-2

Then simplify

20-10/4-2 = 10/2 = 5/1 = 5

So, this means the rate of change is 5. $5 per bushel.

If you also need part B it would be helpful to see the other chart because it's hard to understand in the writing you included. :) Comment and let me know if you post it so I can help you out!

Part A: 7 dollars  

- The graph shows that 2 bushels is 14 dollars,  because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and  rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five  To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

Answer:

1/80 or 0.01234568

Step-by-step explanation:

Exponentiation: (-3) ^ (-9) = -5.08052634253E-5 = -1/

19683

Exponentiation: (-3) ^ 5 = -243

= -1/

19683

* (-243) = -1 · (-243)/

19683 · 1

= 243/

19683

= 1 · 243/

81 · 243

The height of up in the tree was the bald eagle is, 352.5 feet

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

You measure the angle of elevation to the eagle to be 67 degrees.

And, The angle of elevation to the eagle to be 67 degrees.

Now, Let the height of up in the tree was the bald eagle is, x

Hence, We can formulate;

⇒ tan 67° = x / 150

⇒ 2.35 = x / 150

⇒ x = 2.35 × 150

⇒ x = 352.5 feet

Thus, The height of up in the tree was the bald eagle is, 352.5 feet

Write the problem as an equation:

5n <65

Solve for n by dividing both sides by 5:

n <13

Because the inequality does not contain an equal sign, n (13) is not included in the answer so there would be an open circle on the number 13

The correct answer would be A.

Answer:

7 m

Step-by-step explanation:

We are told that;

100 cm = 1 m

Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m

This means that;

1 inch = 0.0254 m

Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m

Approximating to the nearest metre gives 7 m
