Answer:

2.57

Step-by-step explanation:

So we know that 1 kg equals to 1000 grams in this case however we have 2570 and to get them to kilograms you can go ahead and divide that by 1,000 because 1000 grams equals to 1 kg whenever you divide 2570 by 1,000 you end up getting 2.57 and that will be your answer.

Answer:

[tex]1)7.81 = a[/tex]

[tex]2)3\pi = b[/tex]

[tex]3) \sqrt{73} = c[/tex]

[tex]im \: not \: 100\% \: sure \: about \: b \: and \: c[/tex]

[tex]but \: i \: think \: i \: got \: it \: right \: \\ hope \: this \: helps[/tex]

From mental and pen paper calculation we came up that a = [tex]7.\overline{81}[/tex], b = √73 and c = 3π.

A number line is a horizonal line in which we can represent all our real numbers.

According to the given question without using a calculator we have to determine locations of √73, 3π and [tex]7.\overline{81}[/tex] on the number line.

For √73 we know, √64 is 8 and √81 is 9 so √73 lies between 8 and 9 on the number line and more closer to √81 as the distance between √73 and √81 is less than √64 and √73.

For 3π we know, π ≈ 3.14 so 3 times of 3 is 9 and 3 times of 14 is 42 so 3 times of .14 is .42 so it is 9 + .42 = 9.42.So it will lie between 9 and 10 and a just closer to 9 than 10.

For, [tex]7.\overline{81}[/tex] it will be in between 7 and 8 and lot closer to 8 (common sense).

Answer:

$121

Step-by-step explanation:

So if the meal cost $100, finding out the percentages is pretty easy.

The sales tax is 6%, and 6% of 100 is simply 6.

15% of 100 is simply 15.

So, adding the total cost of the meal plus the sales tax plus the tip is simply $121.

Answer:

3/50

Step-by-step explanation:

Slope m = y2-y1/x2-x1

From the coordinate

x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5

Substitute;

m = (3/5 - 2/3)/-4/9-2/3

m = (9-10/15)/(-4-6/9)

m = -1/15/-10/9

m = -1/15 * -9/10

m = 9/150

m = 3/50

Hence the slope of the line passing through the points is 3/50

Answer:

Step-by-step explanation:

Answer:

A square is defined as a quadrilateral with 4 sides of the same length and 4 right angles. To verify the lengths of the sides, you can use the distance formula. To find the angles, you can use the slopes of the line segments and make sure sides that form an angle have opposite reciprocal slopes.

Step-by-step explanation:

First, find the coordinates of each point. You're provided with the scale and you can just count, but to make it easier, you can label the axes.

A: (0,8)

B: (6,6)

C: (4,0)

D: (-2,2)

The distance formula is used to find the distance between any two points on the coordinate form. Here it is:

d=sqrt((y2-y1)^2 + (x2-x1)^2)

d=distance, and (x1, y1) and (x2, y2) are the points.

Find the length of each side. I'll demonstrate with two sides, AB and BC.

AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)

d=sqrt((6-8)^2 + (6-0)^2)

 =sqrt((-2)^2 + 6^2)

 =sqrt(4+36)

 =sqrt(40)=2sqrt10

BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)

d=sqrt((4-6)^2 + (0-6)^2)

 =sqrt((-2)^2 + (-6)^2)

 =sqrt(4+36)

 =sqrt(40)=2sqrt10

Do the same thing with sides CD and AD, you'll see that they both also have a length of 2sqrt10 inches. (You don't really have to simplify, I just like to.)

To verify if the sides are perpendicular, you need to find the slopes of the sides and make sure that the product of the slopes of each pair of sides that form a vertex is -1. In other words, each pair of sides that form a vertex have to have opposite reciprocal slopes. I'll demonstrate with 2 vertecies, A and B.

To find the slope, you have to use the formula m=(y2-y1)/(x2-x1). m is the slope, and again, (x1, y1) and (x2, y2) are the points you're plugging in.

To find the measure of angle A, you need to find the slopes of sides AD and AB. (These are the sides that meet to form the angle.)

AD: (x1,y1)=(0,8) and (x2,y2)=(-2,2)

m = (2 - 8)/(-2 - 0)

   = -6/-2

   = 3

AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)

m = (6 - 8)/(6 - 0)

   = -2/6

   = -1/3

So AD has a slope of 3 and AB has a slope of -1/3. Now you need to make sure they have a product of -1.

-1/3 * 3 = -1

So yes, it works! As I mentioned before, you can also think of them as opposite reciprocals.

The reciprocal of 3 is 1/3. The opposite of 1/3 is -1/3. So yes, the sides are perpendicular.

Let's do it again with angle B. We have to find the slope of BC now, since we already know the slope of AB.

BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)

m = (0 - 6)/(4-6)

   = -6/-2

   =3

So the slope is exactly the same as the slope of AD. A square is a parallelogram, so it has two pairs of opposite parallel sides. We already verified that 3 and -1/3 are opposite reciprocals, so we now know that angle B has a measure of 90 degrees as well. You can do the same for angles C and D. That way, you'll have proven that all the sides have the same length and all the angles measure 90 degrees-- so the quadrilateral ABCD matches the definition of a square.

Step-by-step explanation:

Here, we want to arrange 8 flags in a row

In the row, there will be 8 places

The first place has 8 flags to be chosen from

The second place has 7 and like that

So mathematically, the number of ways that we can arrange the flags is 8 factorial ways

We have this as:
