Factor completely 3x^2+33x+90=?

Answers

Answer:

3(x+5) (x+6)

Step-by-step explanation:

The factored form of 3x² + 33x + 90 is: 3(x + 6)(x + 5)

To factor completely the quadratic expression 3x² + 33x + 90, we can look for two binomial factors that multiply together to give us the original expression.

First, we can check if the expression can be factored by using the common factor 3:

3x²+ 33x + 90

We can factor out 3 from each term:

3(x^2 + 11x + 30)

Now, we need to find two binomial factors that multiply to give us x² + 11x + 30.

The factors can be determined by factoring the quadratic expression further:

x² + 11x + 30 = (x + 6)(x + 5)

Therefore, the completely factored form of 3x² + 33x + 90 is:

3(x + 6)(x + 5)

Step-by-step explanation:

I'm pretty sure it's asking for the circumference. The formula for finding the circumferene is C=πd (d=diameter) First, you need to fiind the diameter. Thequestion gives you the radius, 6.5, which is half the diameter. multiply that by 2 and you get 13. The question says to use 3.14 as π, so just multiply 3.14 by 13 and you get 40.82, which rounds to 41.

Answers

Given:

Students from Williams Middle School are also recycling aluminum cans. The data for the numbers of cans brought in each school day for a month were divided by quartiles and summarized in the box plot.

We need to determine the Median, Interquartile range and Range.

Median:

The median is the middle value of the given set of data.

From the box plot, it is obvious that the median line is at 18.

Thus, Median = 18

Hence, the value of the median is 18.

Interquartile range:

The interquartile range is can be determined by finding the difference between the ends of the box in the box plot.

From the box plot, we have;

Interquartile range = 20 -16

Interquartile range = 4

Hence, the value of the interquartile range is 4.

Range:

The range can be determined by subtracting the highest and the lowest value in the given set of data.

From the box plot, the range can be determined by subtracting the ends of the line.

Thus, we have;

Range = 28 - 10

Range = 18

Hence, the value of the range is 18.

Answer:

Median:  18

Interquartile range:  4

Range:  18

Step-by-step explanation:

∠X and ∠Y and ∠W and ∠Z are linear angles and supplementary angles, and ∠Y and ∠Z are complementary angles. Then the correct options are A, B, and E.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

∠X and ∠Y are linear angles and supplementary angles.

∠W and ∠Z are linear angles and supplementary angles.

∠Y and ∠Z are complementary angles.

A square napkin is folded in half on the diagonal and placed on the diameter of a round plate
(see diagram below).
If the folded napkin spans the plate and the plate has an 18-inch diameter, what is the area of
the space on the plate that is NOT covered by the napkin? Leave your answer in terms of .

Answers

Answer:

The area of  the space on the plate that is not covered by the napkin is[tex]81(\pi-1)\ in^2[/tex]

Step-by-step explanation:

step 1

Find the area of the plate

The area of a circle is given by the formula

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=18/2=9\ in[/tex] ---> the radius is half the diameter

substitute

[tex]A=\pi (9)^{2}\\A=81\pi\ in^2[/tex]

step 2

Find the area of the square napkin folded (is a half of the area of the square napkin)

we know that

The diagonal of the square is the same that the diameter of the plate

Applying Pythagorean theorem

[tex]D^2=2b^2[/tex]

where

b is the length side of the square

we have

[tex]D=18\ in[/tex]

substitute

[tex]18^2=2b^2[/tex]

solve for b^2

[tex]b^2=162\ in^2[/tex] -----> is the area of the square

Divide by 2

[tex]162/2=81\ in^2[/tex]

step 3

Find the area of the space on the plate that is NOT covered by the napkin

we know that

The  area of the space on the plate that is NOT covered by the napkin, is equal to subtract the area of the square napkin folded (is a half of the area of the square napkin) from the area of the plate

so

[tex]A=(81\pi-81)\ in^2[/tex]

simplify

[tex]A=81(\pi-1)\ in^2[/tex]

6x=3y+5

Which statement best describes the relationship between the lines?

Answers

Answer: i think is A they are parallel

Step-by-step explanation: is not  perpendicular NOT-B

Final answer:

The relationship between the lines represented by the equations 12y = 24x and 6x = 3y + 5 is that they are parallel lines. This conclusion is drawn from the fact that they have the same slope (2) but different y-intercepts (0 for the first line and -5/3 for the second line).

Explanation:

To determine the relationship between the lines represented by these equations, we must first put them in slope-intercept form (y = mx + b), where m represents the slope of the line, and b indicates the y-intercept.

For the first equation, 12y = 24x, we can divide both sides of the equation by 12 to get y = 2x.

For the second equation, 6x = 3y + 5, we re-arrange the equation by subtracting 5 from both sides and then dividing by 3. This gives us y = 2x - 5/3.

From the equations y = 2x and y = 2x - 5/3, we can see that the slopes of both lines are the same which is 2. This indicates that the lines are parallel to each other. However, since the y-intercepts are different (0 for the first line and -5/3 for the second line), we can conclude that they are different parallel lines, not the same line.

The angle θ=π3 is in standard position and has a terminal side that coincides with the graph of a proportional relationship represented by y=kx.

a. Find the constant of proportionality, k.

b. Write an ordered pair that lies on the graph of y=kx.

Answers

Part a

theta = pi/3

sin(pi/3) = sqrt(3)/2

cos(pi/3) = 1/3

tan(angle) = opposite/adjacent = rise/run = slope

tan(pi/3) = sin(pi/3)/cos(pi/3) = (sqrt(3)/2)/(1/2) = sqrt(3)

The value of k is k = sqrt(3)

This is also the slope the line y = kx because it is in the form y = mx+b with m = sqrt(3) and b = 0.

===============================================

Part b

Pick any value you want for x, and plug it in to find the paired value of y

if x = 0, then y = 0 because

y = sqrt(3)*x = sqrt(3)*0 = 0

So (0,0) is one ordered pair on the line

---------

If x = 1, then y = sqrt(3), since,

y = sqrt(3)*x = sqrt(3)*1 = sqrt(3)

We can say ( 1, sqrt(3) ) is another ordered pair

---------

If x = sqrt(3), then,

y = sqrt(3)*x = sqrt(3)*sqrt(3) = sqrt(3*3) = sqrt(9) = 3

Therefore, ( sqrt(3), 3 ) is another ordered pairThere are infinitely many ordered pairs on this line.

Jackie cut a piece of paper along its diagonal, as shown below, forming two triangles.

The two heights are the same in the triangles as they were in the rectangle, but the bases of the triangles are half the length of the base of the rectangle.

The two bases of the triangles have the same length as the base of the rectangle, but the triangles have heights equal to half the height of the rectangle.

The two dimensions of the triangles are each half what they were in the rectangle.

Answers

Answer:

B. The two dimensions are the same in the triangles as they were in the rectangle.

Step-by-step explanation:

Given

Initial Shape: Rectangle (Before cut)

Final Shape: Triangles (After cut)

Note that this can be explained properly with the use of attachments

See attachment 1 for Before Cut

Before Cut represent the full rectangle before Jackie cut the piece of paper.

Let H and B represent the height and base of the triangle

Given that the rectangle is cut diagonally, this means that the cutting starts and ends at the opposite edges of the rectangle

See attachment 2 for After Cut

After Cut represent the two triangles after cutting the rectangle

From the attachment, you'll observe that the dimension of the two triangles (Triangle 1 and Triangle 2) are the same as it is with the rectangle;

In other words, the two triangle have their heights as H and their bases as B.

Hence, it can concluded that the two dimensions are the same in the triangles as they were in the rectangle.

Solving systems of equations using any method

Answers

Final answer:

To solve the system of equations, use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite. Add the two equations together to eliminate 'x' and solve for 'y'. Substitute the value of 'y' into one of the original equations and solve for 'x'. The solution to the system of equations is x = -5/2 and y = -1.

Explanation:

To solve the system of equations:

4x + 9y = -19

-4x - 7y = 13

We can use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite:

16x + 28y = -52

Now, add the two equations together to eliminate 'x':

37y = -39

Divide both sides by 37:

y = -1

Substitute the value of 'y' into one of the original equations:

4x + 9(-1) = -19

4x - 9 = -19

Add 9 to both sides:

4x = -10

Divide both sides by 4:

x = -10/4 = -5/2

Therefore, the solution to the system of equations is x = -5/2 and y = -1.

Find the volume of a triangular pyramid with a base height of 5 inches, base length of 3 inches, and a height of 6 inches.

Answers

Final answer:

The volume of the triangular pyramid is calculated by finding the area of the triangular base and then using the volume formula for a pyramid, resulting in a volume of 15 cubic inches.

Explanation:

To find the volume of a triangular pyramid, we use the formula for the volume of a pyramid, which is V = (1/3) × base area × height. First, calculate the area of the triangular base using the formula for the area of a triangle, A = (base length × base height) / 2. In this case, the base length is 3 inches, and the base height is 5 inches.

Therefore, the area of the triangle is A = (3 in. × 5 in.) / 2 = 7.5 in.². Now, we can calculate the volume of the pyramid using the height of the pyramid, which is 6 inches.

The volume of the pyramid is V = (1/3) × 7.5 in.² × 6 in. When you calculate this, you get V = 15 in.³, which is the volume of the pyramid.

When you just can't stay silent on a particular issue, expressing your views through civil protest is a positive way to make a difference. Gathering with other people to collectively speak out against wrongdoing is a fundamental right. It can also be a powerful way to bring about change.Part One: Organizing The ProtestSet A GoalProtests can function as a way to spread awareness about an issue. They can also put pressure on those in power to make a specific change. What do you hope to accomplish with your protest? Figure out who the audience of your protest will be. Then plan your strategy from there. You're more likely to get the outcome you want if you take time to set a goal for achieving it.For example, let's say you want to stage a protest at a local factory farm as a way to spread awareness about how animals are treated there. Your goal is to convince people to stop buying their products until something changes. In this case your audience is the public.In some cases your goal might be quite large in scale, like if you're protesting a war or a governmental policy. In this case the protest can be used as a tool to show political leaders that their constituents want a change. Match the meaning to the Native American word.
