Answer:

1. $21

2. $56

Step-by-step explanation:

1.

100% - 30% = 70%

70% * $30 = 0.7 * $30 = $21

2.

100% - 20% = 80%

80% * $70 = 0.8 * $70 = $56

Step-by-step explanation:

The equation for percentages is (percent over 100) times (x over total)  

So for the table the equation is 30/100 * x/30

You cross multiply your total x percent and divide by 100.

So 30 * 30 = 900

900 / 100 = 9

30% of 30 is 9.

Now subtract your answer from the original total (30 - 9 = 21)

So the sale price of the tennis table is $21.

Now repeat for your other equation

Your equation is 20/100 * x/70

So 20 * 70 = 1400

1400 / 100 = 14

20% of 70 is 14.

Now subtract your answer from the original total (70 - 14 = 56)

So the sale price of the easel is $56.

Answer:

If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.

Step-by-step explanation:

From statement, we know that measure of the angle ABC is equal to the sum of measures of angles ABD (section 1) and DBC (section 2), that is to say:

[tex]m \angle ABC = m\angle ABD + m\angle DBC[/tex] (1)

If we know that [tex]m\angle ABC = 40^{\circ}[/tex], [tex]m\angle ABD = 2\cdot x + 3[/tex] and [tex]m\angle DBC = 4\cdot x + 7[/tex], then the value of [tex]x[/tex] is:

[tex](2\cdot x + 3)+(4\cdot x + 7) = 40^{\circ}[/tex]

[tex]6\cdot x +10^{\circ} = 40^{\circ}[/tex]

[tex]6\cdot x = 30^{\circ}[/tex]

[tex]x = 5[/tex]

Then, we check the angles of each section:

Section 1

[tex]m\angle ABD = 2\cdot x + 3[/tex]

[tex]m\angle ABD = 13^{\circ}[/tex]

Section 2

[tex]m\angle DBC = 4\cdot x + 7[/tex]

[tex]m\angle DBC = 27^{\circ}[/tex]

If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.

Answer:

52 degrees

Step-by-step explanation:

A triangle's angles all add up to 180 degrees so we can create this equation:

x + 20 + 3x + 32 = 180

Combine like terms.

x + 3x + 20 + 32 = 180

4x + 52 = 180

Subtract 52 from both sides.

4x = 128

Divide.

128 / 4 = 32

x = 32

Plug in the value of x.

x + 20

32 + 20

52

Angle D is equal to 52 degrees.

Answer:

The possible combinations of two letters is 12

Step-by-step explanation:

Here, we want to count the possible combinations of two letters

Now, for the first letter any point in time, we have 4 letters to pick from,

For the second letter we have 3 letters to pick from

So therefore, we have the possible combinations as;

4 * 3 = 12

Answer:

6

Step-by-step explanation:

The method you were doing was for permutation (nPr) and the question needs you to do the method for combinations (nCr).

Answer:

No.

Step-by-step explanation:

If it is a regular polygon then the sum of its exterior angles add up to 360 degrees. The number of sides in such a polygon  = 360 / exterior angle.

Here each exterior angle = 180-169 = 11 degrees,

Now 11 is not a factor of 360 and if we try to find the number of sides we don't get a whole number, so the answer is NO.

An interior angle 169° cannot form an regular polygon.

The polygons are the closed shape that has sides and vertices. A regular polygon has all its interior angles equal to each other.  An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon.

For the given situation,

An interior angle of the polygon = 169

The angle of the sum of all the types of interior angles is always equal to 180 degrees.

⇒ [tex]180-169=11[/tex]

Number of sides can be found by dividing the angle by 360°.

We cannot divide 360 by 11, because 11 is not the factor of 360.

Hence we can conclude that an interior angle 169° cannot form an regular polygon.

Answer:

the slope is 1 so D

Step-by-step explanation:

Answer:

D.1

Step-by-step explanation:

Hello There!

Given two points we can use the slope formula to identify the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Where the x and y values derive from the points given

So all we have to do is plug in the x and y values from the given points

so

slope =

[tex]\frac{8-3}{3-(-2)} \\8-3=5\\3-(2)=5\\\frac{5}{5} =1[/tex]

So we can conclude that the answer is D. 1

Step-by-step explanation:

We start by subtracting the 6 from the 14, to get the leftover space on the wall, 8 feet. We then divide that by two, since if the painting is centered there will be two equally-sized spaces on either side of it. This means that X = 4 feet.

Step-by-step explanation: took test

In table, the rows represent whether or not a student signed up for swimming, and the columns represent whether or not a student signed up for canoeing.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

To create a two-way table summarizing the data, we need to list the categories we are interested in and then fill in the counts for each combination of categories.

In this case, we are interested in the categories of swimming and canoeing, and we want to know how many students signed up for each combination of the two activities.

                       Canoeing            No Canoeing

Swimming          28                           43

Not swimming    34                           45

Hence,  the rows represent whether or not a student signed up for swimming, and the columns represent whether or not a student signed up for canoeing.
