The third figure has 15 tiles

The 4th figure has 24 tiles

The 5th figure has 35 tiles

The 6th figure has 48 tiles

Each time we increased row and column

So the rule is

n = 46

The number of tiles in figure 46 is 2208

Depending on the angle we are analyzing on the right triangle, each side of it takes a different name. In this case, we are going to name them depending on the angle A. Then,

a: opposite side (to A)

b: adjacent side

c: hypotenuse

We know that the formula for cot(A) is:

Replacing it with a and b:

Since a = 3:

We have an expression for cot(A) but we do not know its exact value yet. First we have to find the value of b to find it out.

We do this using the Pythagorean Theorem. Its formula is given by the equation:

Since

a = 3

and

c = √51

Then,

solving the equation for b:

Then,

b= √42

Therefore, the equation for cot(A) is:

-(x+ 5) + 3x

Distributing the -1:

(-1)*x + (-1)*5 + 3x

-x - 5 + 3x

Combining similar terms:

(-x + 3x) - 5

2x - 5

Step-by-step explanation:

since M is the midpoint, it means that AM = MB.

so,

b² + 5b = 3b + 35

b² + 2b - 35 = 0

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case (x is called b, don't get confused, as this is not the factor of x) this gives us

b = (-2 ± sqrt(2² - 4×1×-35))/(2×1) =

= (-2 ± sqrt(4 + 140))/2 = (-2 ± sqrt(144))/2 =

= (-2 ± 12)/2 = -1 ± 6

b1 = -1 + 6 = 5

b2 = -1 - 6 = -7

therefore, we have 2 solutions

b = 5

AM = 5² + 5×5 = 25 + 25 = 50

b = -7

AM = (-7)² + 5×-7 = 49 - 35 = 14

control, as AM = MB

MB = 3×5 + 35 = 15 + 35 = 50

or

MB = 3×-7 + 35 = -21 + 35 = 14

AM = MB in both cases, so, all is correct.

To graph, a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equals sign. The graph of this equation is a line.

If the inequality is strict ( < or > ), graph a dashed line. If the inequality is not strict ( ≤ and ≥ ), graph a solid line.

For example,

Consider the linear inequality in two variables below

Always remember that the slope is the number of units on the Y-axis in relation to the X movement.

A horizontal line always has a slope of 0. (it is not increasing in the Y-axis)

The domain of a function is all values of x the function can have.

Since this function has radicals, and the value inside a radical needs to be positive or zero, and also the denominator of a fraction can't be zero, we have the following conditions:

Since the first condition contains the second, so the domain set is represented by the second condition:

Given the System of Inequalities:

1. Take the first inequality and solve for "y":

Notice that direction of the symbol changes, because you had to multiply both sides of the inequality by a negative number.

Now you can identify that the boundary line is:

Since it is written in Slope-Intercept Form, you can identify that its slope is:

And its y-intercept is:

Notice that the symbol of the inequality is:

That indicates that the line is dashed and the shaded region is above the line.

Knowing all this information, you can graph the first inequality on the Coordinate Plane.

2. Apply the same procedure to graph the second inequality. Solving for "y", you get:

Notice that the boundary line is:

Where:

Since the symbol is:

The line is dashed and the shaded region is above the line.

Knowing this, you can graph the second inequality.

3. Look at the graph of the System of Inequalities:

Notice that:

-The black line is the boundary line of the first inequality and the green line is the boundary line of the second inequality.

- The solution of the system is the intersection region. It is the region where the shaded region of the first inequality and the shaded region of the second inequality, intersect.

4. Plot the points given in the options on the graph of the Systems:

5. You can identify that this point is in the intersection region:

Therefore, it is a solution.

Hence, the answer is: Option B.

Answer:

length: 21 cm

width: 16 cm

Step-by-step explanation:

. A rectangle has two lengths and two widths, or two sides that are vertical (up and down) and two sides that are horizontal (left and right)

. In order to find the perimeter we must add up all four side lengths.

. You can find the perimeter of a rectangle by adding the length and the width then multiplying by 2, because there are two of each side length.

P = 2(l+w)

In the question the perimeter is given, which is 74.

We can divide 74 by 2 so that we can find the sum of the length and width.

74/2 = 37

l + w = 37

In the question is states that the length is 5 inches longer than the width.

l = (5 + w)

There are two widths and two lengths in a rectangle, the measurement of the two lengths is 5 inches longer than the two widths.

5 + w + w = 37

5 + 2w = 37

Now that we have our equation we can solve for w, or the width.

1. Move the term containing the variable to the left

5 + 2w = 37

2w + 5 = 37

2. Subtract 5 from both sides of the equation, the opposite of adding 5

2w + 5 = 37

2w + 5 - 5 = 37 - 5

2w = 32

3. Divide by 2 in both sides of the equation, the opposite of multiplying 2

2w = 32

2w/2 = 32/2

4. Cancel out the 2s on the left, but leave the x

2w/2 = 32/2

w = 16

So, now that w, or the width = 16, we can find the length:

l = 5 + w

l = 5 + 16

l = 21

You can check your answer by plugging in our values into the original perimeter formula:

P = 2(l+w)

P = 2(21 + 16)

P = 2(37)

P = 74, so my answer is correct, because 74 is the perimeter given in the question.

3(y-4) - 5(y+8)

3y - 12 - 5y - 40

-2y - 52

Given that 11v - 8 = 3

add 8 to both sides

11v = 3 + 8

11v = 11

Divide both sides by 11

v = 1

to simplify 4v - 8

= 4 (1) - 8

= 4 - 8

= -4

Tyrone randomly interviewed 55 8th graders at the Westwood Mall Saturday afternoon to determine their reason for going to the mall.

Based on the results he made the following claim.

"Two out of four middle school students visit the mall to go shopping".

Let us analyze each of the given options.

a. Tyrone only interviewed students in the food court.

There is no evidence that suggests the interview was conducted at the food court so this is not the correct answer.

b. Tyrone did not survey enough 8th graders to draw a valid conclusion

He interviewed 55 8th graders which are more than enough students so this is not misleading.

c. Tyrone did not use a random sample of 8th graders

It is given in the question that he used a random sample so this is not misleading.

d. Since Tyrone surveyed only 8th graders, his sample is not representative of all middle school students.

If you notice closely, Tyrone interviewed only 8th graders whereas the claim was about all middle school students.

So this is clearly misleading, 8th graders do not represent all middle school students.

Therefore, option d is correct.

Answer:

Surface area = 1084 in²

Step-by-step explanation:

To find the surface area of a right cone, we can use the following formula:

[tex]\boxed{{Area = \pi r^2 + \pi rl}}[/tex],

where:

• r = radius

• l = slant height.

In the question, we are told that the diameter of the cone is 30 in. Therefore its radius is (30 ÷ 2 = ) 15 in. We are also told that its height is 8 in.

Using this information and the formula above, we can calculate the surface area of the cone:

Surface area = [tex]\pi \times (15)^2 + \pi \times 15 \times 8[/tex]

                     = [tex]345 \pi[/tex]

                     [tex]\approx[/tex] 1084 in²

To be a function, it is nesessary that the values of x correspond to a unique value of y (a value of x cannot correspond to 2 different values of y). The same value of y can correspond to two or more values of x

As in the given data each value of x has just one value of y. Then, it is a function.

If both triangles are congruent by the HL theorem, then their hypotenuses are equal and at least one of the corresponding legs is equal too.

Hypothenuses:

From this expression, you can calculate the value of m

Legs:

Replace the expression with the calculated value of m

Now pass the n-related term to the left side of the equation and the numbers to the right side:

And divide both sides of the expression by 3

So, for m=3 and n=6 the triangles are congruent by HL
