can someone please help me with this question?

Answer:

Step-by-step explanation:

Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

a). A(-6, -4), B(-3, -1)

Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]

                                             = [tex]\sqrt{9+9}[/tex]

                                             = 3√2

                                             = 4.2 units

b). C(3.5, 1), D(-4, 2.5)

Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]

                                              = [tex]\sqrt{58.5}[/tex]

                                              = 7.65

                                              ≈ 7.7 units

c). Distance between X(5, -5) and Y(-5, 5)

    Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]

                    = [tex]\sqrt{200}[/tex]

                    = 10√2

                    = 14.14

                    ≈ 14.1 units

Answer:

The answer is 9.625

Step-by-step explanation:

So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5

38.5 / 4 = 9.625

To double check just multiple 9.625 by 4

9.625 x 4 = 38.5

Answer:

k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]

Step-by-step explanation:

|19 - 3k| = 3

-3k = 3 - 19

-3k = -16

k = 16/3

k = 5 1/3

-19 + 3k = 3

3k = 3 + 19

3k = 22

k = 22/3

k = 7 1/3

Answer: -1/5

Step-by-step explanation:

Answer:

The second one -1/5.

Step-by-step explanation:

1-2=-1 for y and 10-5=5 for x -1/5.

Answer:

x = 36 degrees

y = 48 degrees

Step-by-step explanation:

The two given triangles are congruent

Hence, we can say that the interior angles are equal

We shall use the angle markings on each of the triangles

Using the markings, we can see that y is 48 degrees

Now, let us find the last angle measure of the first triangle

Mathematically, the sum of angles in a triangle is 180

Thus;

108 + 48 + A = 180

A = 180 - 48 - 108

A = 180 - 156 = 24

Now, the measure 2x-y is equal to this;

Hence;

2x -y = 24

2x = 24 + y

we have that y = 48

2x = 24 + 48

2x = 72

x = 72/2

x = 36 degrees

Answer:

12.5%

Step-by-step explanation:

Given data

Number of bicycles sold last year= 655

Number of bicycles sold this year= 582

%percent change= Iniitial -FInal/initial *100

%percent change= 655-582/582*100

%percent change= 73/582 *100

%percent change=0.125 *100

%percent change=12.5%

Hence the percent change is 12.5%

Answer:

115

Step-by-step explanation:

The number of students that  should the teacher predict will participate in the program is option C. 108 students

Since 15% of the students would be interested in a summer creative writing program and there are 720 students

So, the number of students should be

= 15% of 720

= 108

Therefore, The number of students that  should the teacher predict will participate in the program is option C. 108 students

Angle of 1 and 3 as 90*

Step-by-step explanation:

This is because all angles are the same meaning all angles are 90*. Even 1 and 3. Brainiest and a thank you?!

Answer:

We really aren't provided with enough information to give you the answer. I'll explain how to find them, but you should comment on my response and tell be if it gives you any values at all to work with.

So, ∠1 and ∠3 are vertical angles, which means they are equal to each other.

Along with that, ∠2 and ∠4 and also vertical angles, so they're equal to each other as well.

Now we have the information:

∠1 = ∠3

and

∠2 = ∠4

__________________________________________________________

Given that both of the two lines are intersecting, each angle has two angles that it is supplementary to.

Supplementary angle are angles that when added together equal exactly 180°.

A perfectly straight line's angle it 180°.

Using this knowledge, you can find that ∠1 is supplementary to ∠2, ∠2 is supplementary to ∠3, ∠3 is supplementary to ∠4, and ∠4 is supplementary to ∠1.

If that's still confusing, here's it explained simpler:

∠1 + ∠2 = 180°

∠2 + ∠3 = 180°

∠3 + ∠4 = 180°

∠4 + ∠1 = 180°

__________________________________________________________

But still - you haven't given us the information to find these values. Are you given even one angle measurement to work with?? If so, comment it here and I'll work it out for you.

Answer:

105 students

Step-by-step explanation:

The computation of the number of students left the school is given below:

Let us assume the total students be  x  and 100%

Left percentage = 84%

Remaining percentage = 100% - 84% = 16%

Now according to the question

16% of x = 20

0.16x = 20

x = 20 ÷ 0.16

x = 125

Total students 125

Those who left is

= 84% of 125

= 105 students
