Consider the segment AB with A positioned at (6,2). The midpoint of AB, M is located at (5, -3). What are the coordinates of point B? * O (7,7) O (4,-8) O (5.5, -0.5) O (4,5)​

Answers

Answer 1

Answer:

I didn't "do the math" yet at all, but draw it out on an X,Y axis...  Thinking about it logically...  If point A is in the upper right quadrant of the axis, because both X and Y coordinates are positive numbers, so you go right on the horizontal axis and up on the vertical axis...  Then the midpoint is in the lower right quadrant of the due to the X coordinate being a positive, thus you go right on the horizontal axis, but the Y coordinate is a negative, so you go down vertically... So point B cannot be above both the midpoint or point A, ruling out (7,7) and (4,5) as both Y coordinates of those answers (7 or 5) are higher than point A's Y coordinate of 2...  B would have to be below point A because the midpoint is below point A with a Y coordinate of -3... So this leaves either option (5,-0.5) or option (4,-8)...  However....  While (5,-0.5) has a lower Y coordinate than point A with -0.5, its Y coordinate is above the Y coordinate of the midpoint as well, since -0.5 is above -3...  So this doesn't jive as point B cannot be between point A and the midpoint to point B...  This logically leaves (4,-8) left to be the answer...  And if you drew on an X,Y axis the coordinates (6,2) as well as (5,-3) and (4,-8), then connect the dots, you'd find (5,-3) sits about half ways between (6,2) and (4,-8)...

So (4,-8) is probably the answer...

The best way to come to this conclusion mathematically is finding the slope (rise over run) of point A and the midpoint between point A and point B, then continuing the slope down, etc...  But this particular question with the multiple choice answers ruled all but 1 answer out...

To find the slope you take rise over run, which is the Y of the 2nd coordinate minus the Y of the 1st coordinate, divided by (or over) the X of the 2nd coordinate minus the X of the 1st coordinate....

IE: ( Y2 - Y1 ) / ( X2 - X1 ) = Rise / Run

So.... The 2nd coordinate's Y value is -3, and the 1st coordinate's Y value is 2...  Subtract 2 from -3, and you get -5...

Then the 2nd coordinate's X value is 5, and the first coordinate's X value is 6...  Subtract 6 from 5, and you get -1...

Divide -5 over -1, which equals the same as 5 over 1...  The rise is 5, the run is 1, the slope is 5 steps vertically for every 1 step horizontally...

Or visually... ( -3 - 2 ) / ( 5 - 6 ) which is -5 / -1...  Since both sides are negative, that's the same as 5 / 1... which is 5 vertical steps (rise) for every 1 horizontal step (run), or a slope of 5...

So add the slope rise of 5 to the Y coordinate of the midpoint, -3, and you get 2, which is the Y coordinate of point A...  And add slope run of 1 to the midpoint X coordinate, 5, and you get 6, the X coordinate of point A...  Now subtract the slope rise of 5 from the midpoint, -3, and you get -8...  So that tells you that point B has to have a Y coordinate of -8....  And now subtract the slope run of 1 from the midpoint X coordinate, 5, and you get 4...  The X coordinate of point B...  Giving you a point B coordinate of (4,-8)...

Answers

Answer:

Angle E is 43 degrees.

Step-by-step explanation:

So we know that AB is parallel to CD.

We also know that Angle CHF is 119 degrees and that Angle B is 18 degrees.

First, let's find Angle DHF. It is the supplementary angle to Angle CHF. Thus, they must total 180:

[tex]\angle DHF+\angle CHF=180[/tex]

We already know that Angle CFH is 119. Substitute:

[tex]\angle DHF+119=180[/tex]

Subtract 119 from both sides:

[tex]\angle DHF=61[/tex]

Therefore, Angle DHF is 61 degrees.

Since Angle DHF is 61 degrees, then angle BGH must also be 61 degrees. This is because they are corresponding angles, and corresponding angles have the same measure.

Also, Angle BGE is the supplementary angle to Angle BGH. In other words:

[tex]\angle BGE+\angle BGH=180[/tex]

Find Angle BGE. Substitute 61 for BGH:

[tex]\angle BGE+61=180[/tex]

Subtract 61:

[tex]\angle BGE=119[/tex]

So, angle BGE is 119 degrees.

Recall that a triangle's interior angles sum to 180. This means that Angle B plus Angle BGE plus Angle E must equal 180. Thus:

[tex]\angle B+\angle BGE+\angle E=180[/tex]

Substitute 18 for B and 119 for BGE. Thus:

[tex]18+119+\angle E=180[/tex]

Add:

[tex]137+\angle E=180[/tex]

Subtract:"

[tex]\angle E=43\textdegree[/tex]

And we're done!

Remarks:

I just realized that you can just use the fact that alternate exterior angles have the same measures to figure out that BGE is equivalent to CHF. Regardless, we will arrive at the same answer :)

Answers

Answer:

The expression 75ℎ represents the total charge for Elegance Home Architects.

If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.

If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.

Step-by-step explanation:

Given the following :

Rock the house digital designs :

Initial consultation charge = $500

Additional hour of work for house plan = $50 /hr

Elegant Home Architect:

Charge = $75 / hr

h = number of hours fro which Johnson's family hires the design firm

Total amount charged by Elegant home Architect = 75 × h = 75h

Total amount charged by Rock the house digital design = (500 + 50h)

If h = 15 hours :

Total amount charged by Elegant home Architect = 75 × 15 = $1,125

Total amount charged by Rock the house digital design = (500 + 50(15)) = 500 + 750 = $1,250

Hence, Elegant home Architect is cheaper.

If h = 40 hours :

Total amount charged by Elegant home Architect = 75 × 40 = $3,000

Total amount charged by Rock the house digital design = (500 + 50(40)) = 500 + 2000 = $2,500

Hence, Rock the house digital design is cheaper.

A band marches in the African American Day Parade in New York City. The band marches 800 meters every 15 minutes. At this rate, how many kilometers does the band march in 1 hour?

Answers

3.2 Kilometers


reasoning:

there are 1000 meters in a kilometer. If they march 800 meters in 15 minutes, in 60 minutes they will march 3200 meters (800x4) . You then divide 3200 by 1000 to get 3.2 kilometers

The band will march 3.2 kilometers at the same rate.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

800 meters for every 15 minutes

800 meters  ⇔ 15 minutes

Multiply 4 by both sides

3200 meters ⇔ 60 minutes

Now,

60 minutes = 1 hour

And,

Since 1000 meter = 1 kilometer ⇒ 3200 meter = 3.2 kilometer.

So,

1 hour ⇔ 3.2-kilometer.

Hence "The band will march 3.2 kilometers at the same rate".

A. 12 ft
B. 12 ft2
C. 14 ft
D. 14 ft2​

Answers

Answer:

12ft²

Step-by-step explanation:

The frame is rectangular in nature, to determine a reasonable value for how much wall space the portrait will cover, we will take the area of the frame.

Given

Length of the frame = 45in

Width of the frame = 37in

Required

Area of the frame

Area of the rectangular frame = Length * Breadth

Area of the rectangular frame = 45in * 37in

Given 1feet = 12in

45in = 45/12 ft=  3.75ft

37 in = 37/12 ft = 3.083 ft

Area of the frame = 3.75ft * 3.083 ft

Area of the frame = 11.56ft²

Area of the frame ≈ 12ft²

The sum of 4 consecutive odd integers is equal to zero. Write an equation to model the sentence.

Answers

Answer: X + (X + 2) + (X + 4) + (X + 6) = 0

Step-by-step explanation:

We were already given the sum of four consecutive integers. Consecutive means coming after another. Let's first define our first consecutive odd number as X. Since it says consecutive odd integers, there is a difference of 2   between two odd numbers. We keep on adding 2 to the value of X, since they asked for four consecutive odd integers, so we get the 4 values of X,  (X+2), (X+4), and (X+6). Once we put this in an equation, we get X + (X + 2) + (X + 4) + (X + 6) = 0.

The equation that models the sentence is :  x + (x + 2) + (x + 4) + + (x + 6)  = 0.

An odd number is a number that cannot be divided into half without any remainders. Examples of odd numbers are 1,3, 7, 11.

For example when 11 is divided in half, its value is 5.5

Consecutive odd numbers are odd numbers that follow each other. Examples are 1, 3, 5.

Consecutive odd numbers increase by 2

In order to model the sentence, let x represent the first odd number

Second odd number = x + 2

Third odd number = x + 4

Fourth odd number = x + 6

The equation is: x + (x + 2) + (x + 4) + + (x + 6)  = 0
