a mason builds two patios with the same area. one is a square and the other is a rectangle 10 m longer than the square but 8 m less wide than the square. what is the area of each patio?

The function that includes all the ordered pairs in the given table is y = -x - 4

First choose two points

First point = (0, -4)

Second point = (2, -6)

The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values in the equation

The slope of the line = (-6 - (-4) / (2 - 0)

= -6 + 4 / 2

= -2 / 2

= -1

Here at X = 0, the value of Y = -4

Therefore the y intercept of the line = -4

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

Substitute the values in the slope intercept form

y = -1x - 4

y = -x - 4

Hence, The function that includes all the ordered pairs in the given table is y = -x - 4

The volume of the rectangular prism is 12 cubic inches

It is given that Each cube represent 1 unit

The base length of the rectangular prism = 4 inches

The base width of the rectangular prism = 3 inches

The height of the rectangular prism = 1 inches

The volume of the rectangular prism = The base length of the rectangular prism × The base width of the rectangular prism × The height of the rectangular prism

Substitute the values in the equation

The volume of the rectangular prism  = 4 × 3 × 1

= 12 cubic inches

The value of x that makes lines u and v parallel is 6. Option A is correct.

First, let us understand the angles formed by parallel and transversal lines:

The different types of angles are alternate exterior angles, alternate interior angles, corresponding angles, consecutive angles, etc.

From the picture attached,

If the lines u and v are parallel and a third line (transversal) is intersecting these lines at two distinct points,

Both the angles given in the picture will be equal in measure as these angles are alternate exterior angles if u and v are parallel.

20x + 10 = 130 degrees

20x = 130 - 10 degrees

x = 120 / 20 = 6

So, the value of x is 6.

Thus, the value of x that makes lines u and v parallel is 6. Option A is correct.

Step-by-step explanation:

The commonly used technique in problem solving is means-end analysis

One typical heuristic is to define subproblems or subgoals. Means-ends analysis, which entails determining how to close the gap between a goal and the actual situation, is another frequently employed heuristic. You can divide a problem into smaller problems and deal with each one separately by using means-ends analysis.

Heuristic problem-solving entails what?

A problem-solving heuristic is a non-formal, speculative process that, in certain circumstances, produces a solution but not in others. The strategy can be either more or less successful than employing an algorithm because the results of applying a heuristic are unpredictable.

For the given standard deviation and sample mean the two sided confidence interval on mean diameter foe 95% and 99% is given by        ( 1.4983 , 1.5107 ) and ( 1.49635 , 1.51265 ) respectively.

As given in the question,

Confidence interval for population mean is given by:

[tex]\bar{x}[/tex] ± z × ( σ / √n)

Where,

σ = population standard deviation.

n= sample size

[tex]\bar{x}[/tex] = Sample mean

Given values from the random sample size are :

σ = 0.01 inches

n= 10

[tex]\bar{x}[/tex] = 1.5045

Critical value confidence interval (using x-value table)

z  for 99% = 2.576 and Significance level = 0.01

z for 95% = 1.960 and Significance level = 0.05

99% two-sided confidence interval on the mean hole diameter is equal to :

[tex]\bar{x}[/tex] ± z × ( σ / √n)

= 1.5045 ± 2.576 × ( 0.01 / √10)

= 1.5045 ± 0.00815 (approximately)

= 1.5045 - 0.00815 , 1.5045 + 0.00815

= ( 1.49635 , 1.51265 )

95% two-sided confidence interval on the mean hole diameter is equal to :

[tex]\bar{x}[/tex] ± z × ( σ / √n)

= 1.5045 ± 1.960 × ( 0.01 / √10)

= 1.5045 ± 0.00620 (approximately)

= 1.5045 - 0.00620 , 1.5045 + 0.00620

= ( 1.4983 , 1.5107 )

Therefore, for the given standard deviation and sample mean the two sided confidence interval on mean diameter foe 95% and 99% is given by ( 1.4983 , 1.5107 ) and  ( 1.49635 , 1.51265 ) respectively.

What is arithmetic sequence?

It is a sequence of numbers which have same difference between two consecutive numbers. The common difference can be any positive number or negative number or even it can be 0.

The six terms of the arithmetic sequence are as follows:

1,7,13,19,25,31

Calculate the common difference as follows:

7-1=6

13-7=6

19-13=6

Since it is an arithmetic sequence hence common difference is 6.

Hence, [tex]d=6[/tex].

Now, substitute value of the first term and the common difference in the following expression of the nth term.

[tex]a_n=a+(n-1)d\\a_n=1+(n-1)6[/tex]

The above expression has brackets

So, we start by expanding the brackets

Solving further, we have

6 + 5(3x - 2) = 6 + 15x - 10

Collect the like terms

This gives

6 + 5(3x - 2) = 15x - 10 + 6

Algebraic expression in mathematics is a phrase that include coefficients, unknown variables  operations, and constants

To solve for y in the equation 10x+5y=5x+20 we apply algebraic rule;

Step 1: Collect the like terms by moving the unknown 'ý' to the left side of the equation

5y =5x -10x+20

Step 2: Evaluate the the expression 5y =5x -10x+20

5y = -5x + 20

Answer:

The angle is approximately 111.199 degrees.

Step-by-step explanation:

Cosine is adjacent over hypotenuse.

The hypotenuse is the longest side of the triangle.  

In this cos the hypoteneuse is a. However, we can only use cos on right triangles and on the angles that are not 90 degrees. In this case, p would be the 90 degree angle if we could use cosine.

In this case, you need the law of cosines, not cosine. The law of cosine says [tex]c=\sqrt{a^2+b^2-2 a b cosp}[/tex] where c is the side opposite to the angle, a and b are the sides adjacent to the angle, and p is the angle. The law of cosine works for all the triangles.

Plugging in the numbers:

[tex]5.3=\sqrt{3.6^2+2.8^2-2*3.6*2.8* cosp}\\5.3^2=20.8-20.16* cosp}\\7.29=-20.16*cosp\\cos^{-1}\frac{7.29}{ -20.16}=p\\p=111.198929[/tex]

The linear function rule of the equation is y =  x + 18

From the question, the points on the line are given as

(2, 20) and (9, 27).

So, we have the following ordered pairs

(x, y) = (2, 20) and (9, 27).

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (2, 20) and (9, 27).

Substitute the known values in the above equation

So, we have the following equation

Slope = (27 - 20)/(9 - 2)

Evaluate the above quotient

Slope = 1

The equation is then calculated as

y = Slope(x - X) + Y

Substitute the known values in the above equation

So, we have the following equation

y = 1 * (x - 2) + 20

So, we have

y =  x + 18

Hence, the equation of the line is y =  x + 18
