What are the possible measures of the triangle’s sides? Select all that apply.

The first step in the construction of a line perpendicular to line AB and passing through an external point m is:

a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB

To construct a perpendicular line, a compass and a scale are used.

Consider a line AB and an external point M.

Step 1:

Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.

Step 2:

Name the two intersecting points on line AB as X and Y.

Draw the arcs from these two points to the opposite side of point M with the same compass width.

Step 3:

Name the intersecting point of two arcs as N.

Draw a line connecting the two points M and N using scale.

Step 4:

Using a protractor, measure the angle of the line MN with the line AB.

The angle must show 90°.

Thus, the line MN perpendicular to line AB and passing through an external point M is constructed.

Answer:

y = -1.3x + 10

Step-by-step explanation:

x_avg = (-2 + -1 + 1 + 2 + 3 + 4)/6 = 1.166666...

y-avg = (21 + 8.6 + 1 + 1 + 5 + 14.3) = 8.48333...

x      y       x-x_avg       y-y_avg          (x-x+avg)²           (x-x_avg)(y-y_avg)

-2    21     -3.1666        12.51666       10.02777                    -39.63611

4     14.3    2.8333        5.81666         8.02777                     16.480555

sum of (x-x_avg)(y-y_avg) = -34.858

sum of (x+x_avg)² = 26.8333

slope = [(x-x_avg)(y-y_avg)/[(x+x_avg)²]

slope = -34.858/26.8333

slope = -1.29907

y = mx + b

y_avg = m(x_avg) + b

8.48333 = -1.3(1.1666) + b

b = 9.9989

y = -1.3x + 10

Answer:

4.35

Step-by-step explanation:

The expected value can be defined as: [tex]\sum{x_i*p_i}[/tex] where x_i = the payout, and p_i = the probability of it occurring.

This gives us the expression: [tex](1 * 0.35) + (2 * 0.2) + (5 * 0.1) + (8 * 0.2) + (10 * 0.15) = 0.35 + 0.4 + 0.5 + 1.6 + 1.5 = 4.35[/tex]

So the expected payout is 4.35

Using it's concept, the probabilities are given as follows:

19. A. 1/3.

20. F. 1/6.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:

p = 4/12 = 1/3.

Which means that option A is correct.

2 papers have a score greater than 12, hence the probability in item 20 is given by:

p = 2/12 = 1/6.

The cost of 2 chairs is = $30

The cost of 1 table = $60

Step-by-step explanation:

Let a table represent x

A chair represents y

4x + 3y = 225.......eq 1

3x + 4y = 195........eq 2

Use elimination method

x - y = 30

x= 30 + y...... Eq 3

Substitute the value of x into equation 1

4(30+ y) + 3y= 225

120 + 4y + 3y= 225

7y + 120= 225

7y= 225-120

7y= 105

y= 15

Substitute the value of y in eq 2

3x + 15 = 195

3x= 195-15

3x= 180

x= 60

Therefore, the cost of 2 chairs is 15 * 2= $30

The cost of 1 table = $60

V = four-thirds pi r cubed = Four-thirds (3.14) (5) cubed

The equation of the line is 3x + y = 1

The points are given as:

(5, −2) and (3, 4)

Start by calculating the slope (m)

m =(y2 - y1)/(x2 - x1)

This gives

m = (4 + 2)/(3 - 5)

Evaluate

m = -3

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -3(x + 2) +5

So, we have:

y = -3x - 6 + 5

Evaluate the like terms

y = -3x - 1

Rewrite as:

3x + y = 1

Hence, the equation of the line is 3x + y = 1

Answer:

b = 21

Step-by-step explanation:

In general for these trig problems look for the angle whose measure you are given or need to find and for the sides you are given lengths or whose sides you need to find.

Given:

side AB = 10 cm

m<C = 25°

Find:

side AC

The angle of interest here is <C whose measure is 25°.

Now look at the given side and the side you are looking for with respect to angle C, the given angle.

For angle C, AC is the adjacent leg.

For angle C, AB is the opposite leg.

Which trig function relates the opposite leg to the adjacent leg?

It is the tangent, since, in general, tan X = opp/adj.

tan C = opp/adj

tan 25° = AB/AB

tan 25° = 10 cm/b

Solve for b.

b × tan 25° = 10 cm

b = 10 cm / tan 25°

Using your calculator, divide 10 by the tangent of 25°.

b = 21.44506...

Answer: b = 21

Answer:

[tex]b = \bf 21 \space\ cm[/tex]

Step-by-step explanation:

• To solve for a side using SOH CAH TOA, first check the angle whose measure is given.

In this case, we know ∠ C is 25°.

• Next we have to figure out the relationships between the given angle and two sides: one side whose length we know, and the other whose length we have to find.

In this case, the side opposite to ∠ C is known to be 10 cm, and the side adjacent to ∠ C is AC, whose length, b, we have to find.

• The trigonometric ratio that relates the adjacent and opposite sides of an angle is tan, where:

[tex]\boxed{tan \theta = \frac{opposite}{adjacent} }[/tex] .

We can use this relationship to calculate the value of b:

⇒ [tex]tan (25 \textdegree) = \frac{10}{b}[/tex]

Solving for b:

⇒ [tex]b \cdot tan (25 \textdegree) = 10[/tex]

⇒ [tex]b = \frac{10}{tan (25 \textdegree)}[/tex]

⇒ [tex]b = 21.45[/tex]

⇒ [tex]b \approx \bf 21 \space\ cm[/tex]  (rounded to the nearest whole number)

Given that:

The linear equations are:

x - 5y = 0

15x + 10y = 17

Solve the equations using elimination method:

Multiply equation 1 by 2

Step-by-step explanation:

The time taken by Millie to catch up with Ben is 6 minutes, solved using the linear equation in one variable and the unit rates provided.

We assume the minutes taken by Millie to catch up with Ben to be x minutes.

The number of words Ben has already typed = 180.

The unit rate for Ben for the typing of words = 30 per minute.

Therefore, words typed by Ben in x minutes = 30x words.

Therefore, the total number of words typed by Ben = 180 + 30x words.

The number of words Millie has already typed = 60.

The unit rate for Millie for the typing of words = 50 per minute.

Therefore, words typed by Millie in x minutes = 50x words.

Therefore, the total number of words typed by Millie = 60 + 50x words.

As Millie needs to catch up with Ben after x minutes, the total number of words typed by them needs to be equal, that is, 60 + 50x = 180 + 30x, which is the required linear equation in one variable.

To find the minutes taken by Millie to catch up with Ben, we solve this linear equation in one variable as follows:

60 + 50x = 180 + 30x,

or, 60 + 50x - 30x = 180 + 30x - 30x {Subtracting 30x from both sides},

or, 60 + 20x = 180 {Simplifying},

or, 60 + 20x - 60 = 180 - 60 {Subtracting 60 from both sides},

or, 20x = 120 {Simplifying},

or, 20x/20 = 120/20 {Dividing both sides by 20},

or, x = 6 {Simplifying}.

Thus, the time taken by Millie to catch up with Ben is 6 minutes, solved using the linear equation in one variable and the unit rates provided.
