Lets solve the question,

Given dimensions are:

Length = 26 feet

Width = 14 feet

concrete walkway with width = c

After installing the concrete walkway dimensions of the walkway will be,

Length = 26 + 2c

Width = 14 + 2c

She wants to build a wooden deck around the pool with a concrete walkway of width = w

Thus the dimensions of the wooden deck around the pool will be,

Length = [tex]26 + 2c + 2w[/tex]

Width = [tex]14 + 2c + 2w[/tex]

Now the perimeter of the wooden deck will be,

Perimeter = 2(length + width)

 [tex]= 2[(26 +2c + 2w) + 2(14 + 2c + 2w)] = 2(40 + 4c + 4w) = (80 + 8c + 8w)[/tex]

Therefore, perimeter of the wooden deck would be: 80 + 8c + 8w

Perimeter = (80 + 8c + 8w)

Answer:1 is exponential. 2 is linear. 3 is neither. 4 is linear. 5 is linear. 6 is exponential. 7a is  exponential. I think 7b could be 10x + y = 10 but I'm not too sure. 7c is (8,4).

Step-by-step explanation:1. the coordinates are moving in an exponential way or something im not sure the correct wording but that is what exponential graphs look like. 2 is a straight line so it is linear. 3 is neither because the graph isn't exponential or linear. 4 is linear because the coordinates are subtracting at the same number. 5 is linear for the same reason at 4. 6 is exponential because the coordinates are multiplied by 2 each time. 7a is exponential because the coordinates are divided by 2 each time. 7b I'm not sure on. 7c is 8/4 because August is the 8th month and the month before (7) is 8 so 8 divided by 2 equals 4. So the 8th month would have to be 4. I hope that helps!

Answer:

x = 20°

Step-by-step explanation:

(4x-10)+x=90

4x-10+x=90

4x+x-10=90

5x-10=90

5x=100

x=20

Answer:

20

Step-by-step explanation:

Straight line angles:

     Angles on a straight line add up to 180°.

 90 + 4x - 10 + x = 180

 90 - 10 + 4x + x = 180

Combine like terms.

         80 + 5x     = 180

Subtract 80 from both sides,

                 5x    = 180 - 80

                    5x = 100

Divide both sides by 5

                      x = 100 ÷ 5

Clayman is 10 years old and Ato is 15 years old

Let the age of Clayman be x

Let the age of Ato be y

If the sum of ages of Clayman and Ato is 25 years. then;

x + y = 25

x = 25 - y ...... 1

In five years time;

Age of Clayman = x + 5

Age of Ato = y + 5

If in five years' time, the age of Ato will twice the age of Clayman now, then;

y+5 = 2x ............. 2

Substitute equation 1 into 2

y +5 = 2(25-y)

y + 5 = 2(30 - y)

y + 5 = 50 - 2y

3y = 45

y = 15

Since x + y = 25

x = 25 - 15

x = 10

Therefore Clayman is 10 years old and Ato is 15 years old

Answer:

the graph of y=x^2-4x is parabola as shown in the image

Step-by-step explanation:

The graph of [tex]y = x^{2} -4x[/tex] by drawing the line y=x-4

so this gives us that the line  y=x-4 satisfies the equation  [tex]y = x^{2} -4x[/tex]

To get points put y = x - 4 in the equation  [tex]y = x^{2} -4x[/tex]

so we get x -4 = x( x- 4)

x =1 and x - 4 = 0

from here we get x = 1,4

now put these values in y = x -4

From here we get y = -3,0

so the points are (1 , -3) and ( 4 , 0)

Plot these on graph and we get the straight line .

Step-by-step explanation:

According to the definition, two triangles are similar if their corresponding angles are congruent and corresponding sides are proportional. Hence, we can find the dimensions of one triangle with the help of another triangle. If ABC and DEF are two similar triangles, then by the help of below-given formulas, we can find the relevant angles and side lengths.

∠A = ∠D, ∠B = ∠E and ∠C = ∠F

To convert 30 miles per hour to feet per minute, we use dimensional analysis in the process.

We have given that, rate using dimensional analysis.

1 hour = 60 minutes.

1 mile is equal to 5280 feet and 1 hour is equal to 60 minutes.
