Hello there! :D

Firstly, I want you to understand an important concept. This has something to do with absolute value. So, although distance is a number, it is neither positive nor negative. It does not necessarily involve value. So, what we are looking for today will not have a negative sign in front of it. We are simply looking for distance!

Let's start with ST, because the distance between those is smaller and therefore I can better explain this to you. T is at the point 19.1, and S is at the point 14. We need to find the amount of distance between the two. How do we do that?

Subtraction! In order to find this value we can subtract the smaller number from the larger number.

19.1-14= 5.1

ST is 5.1

Now we can look at the distance between TR. We are actually going to add numbers together! We know that T is 19.1. If we were to put a dot at zzero and measure that distance, it would be 19.1. What is the distance from R to zero? That's right! The same principle is there. If we had a dot at zero and we're measuring from 4, the distance would be 7.5 (even though it is negative on the number line).

So, we can add these numbers together!

19.1+7.5= 26.6

TR is 26.6

I hope this helped you and you have a wonderful day,

Step-by-step explanation:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Three examples of objects that have potential energy are,  a child at the top of the seesaw in play-ground, water in dam, rock kept at some finite height of hill.

What is Potential Energy ?

The energy possessed by a body due to its position or configuration is known as potential energy. when an object is at rest, velocity is equal to zero, thus velocity of the object doesn't contribute to potential energy, it only depends upon gravitational constant "g", height h of the object above the Earth's surface and mass m of the object.

The basic formula to determine the Potential Energy possessed by the body is given by :

P.E = mgh

examples of objects that are having potential energy are :

1) a child at the top of the seesaw in play-ground.

2) water in dam.

3) rock kept at some finite height of hill.

Answer:

The complement is 50 and the supplement is 140

Step-by-step explanation:

Complementary angles add up to 90. Supplementary angles add up to 180. We simply need to subtract to find the difference to fill the gap.

90-40=50

180-40=140

The complement is 50 and the supplement is 140

Answer:

complement angle to 40 degrees is 50 and the supplement angle to 40 degrees is 140

Step-by-step explanation:

complement angle to 40 degrees is 90 - 40 = 50 degrees

Supplement angle to 40 degrees is 180 - 40 = 140 degrees.

FH is FG = GH    which is 4+15=19

Step-by-step explanation:

In order to meet at point F, line DF must travel from the top line to the bottom line. If it crosses through E, the midway, that means that it is halfway to the bottom line. This means the distance D E is equal to E F, because both are the distance from midpoint E to one of the sides (top or bottom).

If D E and E F are equal length, then AB and BF must be the length as well, as it is the length DF line takes to get halfway down from the top. Since they are the same length, A F must be twice the length of AB.

Answer:

I guess that you want to model the elevation of Lake Sam Rayburn.

During the summer, it is 165 ft above the sea level (the sea level is our position 0ft).

If it does not rain, the elevation of the lake decreases by 0.5ft each week.

So if we assume that there is no rain, we can write the elevation fo the lake as a linear relationship with slope equal to -0.5ft and y-intercept equal to 165ft.

L(w) = 165ft - 0.5ft*w

Where w is the number of weeks without rain, if we have 0 weeks without rain, then the level of the lake remains constant at 165ft above sea level,

L(0) = 165ft - 0.

Step-by-step explanation:

You had a typo and said that Phil weighed both amounts so I'm assuming that the second amount is Bill's weight

We can use LCM for this

So lets make a list for both of them

Phil:120, 130, 140, 150, 160, 170, 180, 190, 200

Bill: 150, 154, 158, 162, 166, 170, 174

As you can see here, after 5 months, they will have the same weight.

We can check our work to.

lets do 120+(10*5)=170

and 150+(4*5)=170

Answer: Robert is correct, irrational numbers are part of real numbers.

Explanation:

In mathematics, numbers are classified into different groups or seats. In the case of real numbers, these are a broad category that includes all numbers that can be represented on a line. Moreover, this category includes smaller categories such as rational numbers, for example, 15, 2.4 or 6/2 that can be represented as fractions, as well as, irrational numbers such as [tex]\pi[/tex] that cannot be fractions. In this context, Jenny is incorrect and Robert is correct because irrational numbers are also real numbers.

Answer:

≈ 197 students

Step-by-step explanation:

Let's start by writing what we know.

150 students sampled

68 prefer soccer

59 prefer basketball

23 prefer swimming

Part A

If 59 students prefer basketball out of the 150 students sampled then we divide 59/150 in order to get the percentage of students that prefer basketball.

59/150 ≈ 39.33%       Remember this is only a sample of the students so it is approximate.

Now that we have the percentage, we can multiply it by the entire student body to get an approximate number of all students that prefer basketball.

39.33% = .3933

.3933 * 500 = 196.66  ≈ 197 students   (because we can't have a partial student we round up)

The best approximation of the number of students in the school who prefer basketball is 197.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The results from a random sample of 150 students' after-school activities at a school are shown.

68 students prefer soccer. 59 students prefer basketball. 23 students prefer swimming.

The percentage of students who prefer soccer will be

[tex]\rightarrow \dfrac{68}{150} = \dfrac{34}{75}[/tex]

The percentage of students who prefer basketball will be

[tex]\rightarrow \dfrac{59}{150}[/tex]

The percentage of students who prefer swimming will be

[tex]\rightarrow \dfrac{23}{150}[/tex]

If there are a total of 500 students in the school. Then the best approximation for how many students in the school prefer basketball will be

[tex]\rightarrow \dfrac{59}{150} \times 500 = 196.667 \approx 197[/tex]

Answer:

mZRST = 155°, mZRSU  = 102°

Step-by-step explanation:

Given that mZRST = (12x - 1)º, mZRSU = (9x - 15),  and mZUST = 53°.

We know that mZRSU + mZUST = mZRST (since S is a common point)

So, (9x - 15)º + 53° = (12x - 1)º

Expanding the brackets we have

9x - 15 + 53 = 12x - 1

collecting like terms, we have

53 - 15 + 1 = 12x - 9x

54 - 15 = 3x

39 = 3x

Dividing through by 3, we have

x = 39/3

x = 13°

So, mZRST = (12x - 1)º

= 12(13) - 1

= 156 - 1

= 155°

So, mZRST = 155°

mZRSU = (9x - 15),  

= 9(13) - 15

= 117 - 15

= 102°

So, mZRSU = 102°

Answer:

The value of k that would make Deanna's claim to be true is k = 4

Step-by-step explanation:

The given transformation that Deanna has a claim for = Rotation

Deanna's claim. the minimum rotation of a polygon about its center that carries the polygon onto itself = The interior angle of the polygon

We note that the rotation of a regular polygon about its center that carries the polygon onto itself = The exterior angle of the polygon

Therefore, given that for a polygon with more than 5 sides, the exterior angle of the polygon < The interior angle of the polygon, Deana statement can be said to be true for the case of a square

Here;

The exterior angle of the polygon = The interior angle of the polygon 90

The value of k which is the number of sides of the polygon, for a square = 4

Therefore, the value of k that would make Deanna's claim to be true is k = 4.

Step-by-step explanation:

The width of the rectangle is (x - 9)

(x + 4)(x - 9)

x^2 - 9x + 4x - 36

x^2 - 5x - 36

Answer:

W = ( x - 9 )

Step-by-step explanation:

The area of a rectangle is equal to the length times the width of the rectangle.

So we can say A = LW

A = (x^2 - 5x - 36)

L = (x + 4)

A = LW

W = A / L

W = (x^2 - 5x - 36) / (x + 4)

W = (x + 4) (x - 9) / (x + 4)

W = (x - 9)
