What is the midpoint of AB

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

Explanation:

It might help to move either line m or line n to make them parallel to one another. This isn't required but it might help to see the answer better.

Angles 1 and 2 are between lines m and n, so they are interior angles. They are alternate interior angles as they are on alternate sides of the transversal line.

Angles 2 and 3 are on the same side of the transversal, and both are above their adjacent parallel line counterpart, so they are corresponding angles.

Angles 3 and 4 are outside the interior region, and they alternate on either side of the transversal. They are alternate exterior angles.

Angles 1 and 4 are corresponding for similar reasons as angles 2 and 3 are.

Angle B=60 degrees

Angle C=180-60=120 (DCB)    

Answer:  The answers are in the steps.

Step-by-step explanation:

A standard form equation says that Ax + By=C

SO we have to set all the equations to be like that.

43.  y = 12x     Subtract 12x from both sides.

    -12x + 1y = 0      In this case -12  is A, 1 is B , and 0 is C.

44 .  -4y =3x -24      subtract 3x from both sides

     -3x - 4y = -24     A is -3 , B is -4, and  C is -24  

45. 4x = 8y - 12         Subtract 8y from both sides.  

   -8y     -8y

  4x - 8y = -12         A is 4, B is -8 and C  is -12  

46. If we are given the equation y=65x and x represent the number of hours spent driving. And it says that how far do you travel in 8 hours then plot 8 into the equation for x and solve for y.

y = 65(8)

y= 520  

They traveled 520 miles in 8 hours .

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

According to the question, data provided in the question is as follows

Given ratio

[tex]\frac{3}{4}[/tex] a pound of direct apples

[tex]\frac{1}{2}[/tex] a pound of dried pears

We can right

[tex]\frac{3}{4} : \frac{1}{2}[/tex]

Now we multiplied it to determine the amount of dried apples that required per pound of dried pears

[tex]\frac{3}{4} \times \frac{1}{2}[/tex]

[tex]\frac{3}{8}[/tex]

Hence the above is the answer and the same is to be considered by taking the pound of direct applies to pound of direct pears so that the correct amount could arrive

The amount of dried apple needed per pound of dried pear is 3/8

The question tells us that

3/4 pound of dried apples : 1/2 pound of dried pears

We are asked to find the amount of dried apples needed per pound of dried pears. To do this, we multiply both ratio together to get it in 1. This means that

3/4 * 1/2 = 3/8.

This then mean that for every pound of dried pear, 3/8 pound of dried apple was mixed.

Answer:

Step-by-step explanation:

The formula for calculating the distance between 2 points is expressd as;

D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates A(-7,1) B(-4,-3) C(3,-5) D(7,-2)

The disyance AB will be expressed as

AB = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates A(-7,1) B(-4,-3)

AB = √(-4-(-7))²+(-3-1)²

AB = √(-4+7)²+(-4)²

AB = √3²+4²

AB = √25

AB = 5

For CD with coordinates C(3,-5) D(7,-2)

CD = √(7-3)²+(-2-(-5))²

CD = √(4)²+3²

CD = √16+9

CD = √25

CD = 5

Congruent sides are sides that are equal. Hence since AB is equal to CD, this means that the distances AB and CD are congruent

Answer:

Yes, line L and line K are parallel because the slopes are equal.

Step-by-step explanation:

From the question given:

Line L contains point A(2, 2) and B(3, 6)

Line K contains point C(0, 5) and D(1, 9)

To know if the lines are parallel, we need to determine the slope of each line.

The slope of each line can be obtained as follow:

1. Determination of the slope of line L.

Line L contains point A(2, 2) and B(3, 6)

x1 coordinate = 2

x2 coordinate = 3

y1 coordinate = 2

y2 coordinate = 6

Slope = Chang in y coordinate / change in x coordinate

Slope = y2 - y1 / x2 - x1

Slope = 6 - 2 / 3 - 2

Slope = 4/1

Slope = 4

Therefore, the slope of line L is 4.

2. Determination of the slope of line K.

Line K contains point C(0, 5) and D(1, 9)

x1 coordinate = 0

x2 coordinate = 1

y1 coordinate = 5

y2 coordinate = 9

Slope = Chang in y coordinate / change in x coordinate

Slope = y2 - y1 / x2 - x1

Slope = 9 - 5 / 1 - 0

Slope = 4/1

Slope = 4

Therefore, the slope of line K is 4.

Summary

Line >>>>>>>>>>> Slope

L >>>>>>>>>>>>> 4

K >>>>>>>>>>>>> 4

From the above calculations, we can see that line L and line K has the same slope.

Therefore, line L and line K are parallel.

Answer: x+12

We know that the area is length * width. Since length is x+4, we know

(x+4) * something = x^2+16x+48.

To find that something, note that 48 (from the right side) = 4 (from the left side) * 12. Why is this important? Well, then we know that the something is x+12.

This is because (x+4) * (x+12) = x^2 + 16x + 48. But just focus on this part: 48. Even if we put like 3x+12 or something, that would work out to 3x^2+28x+48. It's 48 every time.

Answer: 3 min

Step-by-step explanation:

Step 1. Find the constant speed

you walked 1000 feet in 15 min

1000 ft/ 15min=200/3 ft / min

Step 2. Apply the constant speed to the left distance

You already walked 1000 feet and it is total 1200 feet

1200-1000=200 feet left

distance ÷ speed=time

200 ÷ (200/3)=3 min

Please let me know if you have any question

Answer:

1 hour

Step-by-step explanation:

Lea's speed = 22km/hr

Trevon's speed = 43km/hr in a direction opposite Lea's

How long does Trevon needs to drive before they are 65km apart.

Note : both took at the same time and in opposite direction.

Recall : speed = distance / time

Distance = speed * time

Distance between them = 65km

Let Trevon's distance = D2 = 43 * t

Lea's distance = D1 = 22 * t

t is the same since they both left at the same time.

D2 + D1 = 65

43t + 22t = 65

65t = 65

t = 65/65

t = 1 hour

Answer:

the answer is 42

Step-by-step explanation:

let the number be ''x''

the difference between ''x'' and 12 can be written as

x - 12

4 times means multiplied by 4, so

4 (x - 12) = 120

4x - 48 = 120

4x = 120 + 48

4x = 168

x = 168/4

x = 42

Answer:

B. 200 km

Step-by-step explanation:

You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation

 170^2 +   150^2 = c^2

28900 + 22500 = c^2

                51400 = c^2

             √51400 = √c^2

                 ~226 = c

They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.

While writing this, I felt like I wasn't explaining well. Please feel free to ask for clarification if you need.

The distance between the planes is closest to 200km

You can use the Pythagorean theorem for this question.

First, we need to find a and b. This is gotten by calculating the distance between North and South, and the East and West. From the question, we can say that, 200 North - 30 North gives 170 miles with respect to the y-axis. In the same vein, we know that 50 East + 100 West gives us 150 kilometers which is with respect to the x-axis.

Since we have found our a and b to be 170 and 150, we then use Pythagoras to find the answer to the equation.

170² + 150² = c²

28900 + 22500 = c²

c² = 51400

c =[tex]\sqrt{51400}[/tex]

c = ±226 km.

Since we can't have distance in negative, then our answer is 226 km. The answer asked us to find the closest distance, and thus, our answer is 200km.

Answer: 216 square units

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

Explanation:

A common pythagorean triple you may be familiar with is the 3-4-5 right triangle. This has two legs of 3 and 4, and a hypotenuse of 5. The perimeter is 3+4+5 = 7+5 = 12. Note how this is a factor of 72.

If we multiply the perimeter (12) by 6, then 12*6 = 72. So we have scaled the triangle by a factor of 6. Each length is 6 times longer

the side length 3 becomes 3*6 = 18

the side length 4 becomes 4*6 = 24

the side length 5 becomes 5*6 = 30

The new perimeter is 18+24+30 = 42+30 = 72

The last step is to find the area. The two legs of this triangle are the base and height

area = 0.5*base*height

area = 0.5*18*24

area = 9*24

area = 216

-----

Or you could find the area of the 3-4-5 right triangle to get

area = 0.5*base*height = 0.5*3*4 = 6

then multiply by 36 to get 6*36 = 216. The 36 is the square of the scale factor 6 we applied above. The new lengths are 6 times longer, so the new area is 6^2 = 36 times larger.
