D is the midpoint of AC, and E is the midpoint of BC, hence the value of x for the given problem will be 9 units.

If the respective sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are comparable (or proportion). Triangles that are similar will have the same shape but may not be the exact same size. According to the fundamental principles of triangles, two triangles are said to be congruent if their size and shape are the same, but two triangles are said to be similar if their shape is the same but their sizes differ. The proportions of similar triangles are the same.

Here,

Since these are similar triangle,

The markup from cost to sale price is $135.

What is the cost price?

Cost price, for instance, equals selling price plus profit ( when selling price and profit are given ) Cost is equal to Selling price plus Loss ( when selling price and loss is given ).

Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)

Given the selling price of the item = $650

The cost = $450

Therefore,

10% × $650 = $585

$585-$450=$135

Hence,  the markup from cost to sale price is $135.

a. Acceleration of the system (a) = 6.125 m/s^2

b. The tension in the rope (T) = 110.25

What is the definition of acceleration ?

Acceleration  defines that the rate at which velocity changes with time, in terms of both speed and direction.

For 30 kg mass

m . g - T = m . a

30 x 9.8  - T = 30. a   ⇒  (1)

For 10 kg mass

T - m base 2 g Sin θ = m base 2 a

T - 10 x 9.8 Sin 30° = 10 x a         ⇒  (2)

a. Adding equation (1) and (2)

    294 - 49 = 30 a + 10 a

    245 = 40 a

     a = 245/40

     a = 6.125 m/s^2

  Therefore, acceleration = 6.125 m/s^2

b. Sub a value in equation (1) we get,

Answer:

2. C

3. BCEF

4. C

Step-by-step explanation:

2. In a function, the x value cannot have two y values (for example: if the points are (1,2) and (1,3) then that is not a function).

In this question, none of the x values repeat with multiple y values, so it is a function. the answer is C.

It is not D, because not all straight lines are functions. If the straight line is vertical, then there is only one x value and it has infinitely many values for y. So, not all straight lines are necessarily functions.

3. Range is the y values. The points are (3,4), (-2,3), (7,1), (2, 1/2)

Here, the y values are 4, 3, 1, and 1/2

Choices B,C,E,F are the answers.

The number of hours will be 10 hours if Eliza and Sahana have agreed to go to the movies the weekend after they have earned the same amount of money.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Eliza has = 14 + 7x

x is the number of weeks

For Sahana:

y - 8.40 = (16.80-8.40)/(2-1)[x - 1]

y = 8.4x - 8.4 + 8.4

y = 8.4x

14 + 7x = 8.4x

x = 10 hours

Thus, the number of hours will be 10 hours if Eliza and Sahana have agreed to go to the movies the weekend after they have earned the same amount of money.

Answer:

Line t:  y = 1/9x + 8

Step-by-step explanation:

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

The formula for finding the slope the line perpendicular to line s is:

[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the line we don't know (in this case, line t) and m1 is the slope of the line we're given (in this case, line s).

Currently line s is in point-slope form or

[tex](y-y_{1})=m(x-x_{1})[/tex].  Since m is the slope, we know that the slope of line s is -9.

By plugging in -9 for m1 in our equation, we have:

[tex]m_{2}=-\frac{1}{-9}\\ m_{2}=-\frac{1}{9}[/tex]

Since we know -1/9 is the slope of line t, we can plug this in for m and (9,9) for x and y in the slope-intercept equation to find b:

[tex]9=1/9(9)+b\\9=1+b\\8=b[/tex]

Thus, the equation of line t in slope intercept form is y = 1/9x + 8

Using the Pythagorean Theorem for the right angled triangles and observing the given figure, The value of x can't be solved because the hypotenuse must be the longest side of the right angled triangle which is violated in this question.

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed. It implies that the internal angles of a triangle add up to 180 degrees.

The required formula is:

The second place player must earn 0.0467 points per game in each of the next three games to take the lead in this category.

What is PPG Statistics?

First, calculate the PPG earned by the current leader of the season.

The total points earned by the current leader amount to 2112 and he had participated in a total of 77 games.

The following formula can be used to determine the PPG earned by the current leader per game,

PPG = Total Points / Total Games

[tex]\implies PPG=\frac{2112}{77}\\ \implies PPG = 27.42[/tex]  -----(1)

Now, calculate the PPG of the player who is ranked in the second place for the season.

The total number of points earned by the second place player is 2020 and he played a total of 74 games.

The second place player earned the following points per game,

PPG = Total Points / Total Games

[tex]\implies PPG=\frac{2020}{74}\\ \implies PPG = 27.29[/tex]  ---(2)

The difference in score with the leading team can be found by subtracting (2) from (1),

[tex]\implies 27.42-27.29=0.13[/tex]

So, to be the leading player, the second place player must obtain a lead of 0.14 points per game in the next three games if the current player plays no more games.

In such a situation, the total PPG of the player should be 27.43 and the number of games to be played is 3.

So, the number of points required to take lead can be calculated as,

PPG = Total Points / Total Games

[tex]\implies 27.43=P/3[/tex]

So, the Total Points required, [tex]P=27.43 \times 3 =82.29[/tex]

And, the PPG required by the second place player to score in each of the next three games is calculated as,

[tex]\frac{0.14}{3}=0.0467[/tex]

Therefore, the second place player must earn 0.0467 points per game in each of the next three games to take the lead in this category.

Keith drove to the mountains last weekend. The trip took 12 hours because of the high traffic on the way there.

Let the distance is D and average rate or speed is x miles.

Distance = speed × time

Substitute the respective values.

D = x  * 12

D= 12x

When Keith drove home, there was no traffic and the trip only took  

hours. The average rate was  8 miles per hour faster on the trip home,

The average rate or speed during return is x+20 miles.

Substitute the respective values in the above formula.

D = (x+20) ×8

D= 8x+160

Equate both the equations.
