What is ruler postulateA line segment has two fixed end points in a line. The length of the line segment is the distance between two fixed points. The length can be measured by units such as centimeters, millimeters, feet or inches
The points on a line are matched one to one with the real numbers in ruler postulate. Coordinate of the point is the real number that corresponds to a point. The distance between points A and B (AB) is equal to the difference of the coordinates of A and B.
As given,
TU = 16, UV = x+4 and TV = 8x -15
TU + UV = TV
16 + x+4 = 8x -15
16 + 4 +1 5 = 8x - x
35 = 7x
x = 35/5
x= 7
We can find UV = x + 4 by substituting the value of x
= 7 +4
= 11
and TV = 8x - 15
= (8*7) - 15
=56 - 15
=41

Given that log 2 = 0.3010 and log 3 = 0.4771, find log √30 without using a calculator.
Answer:
0.73855.
Step-by-step explanation:
log √30
log 30^1/2
= 1/2 log 30
30 = 2 * 3 * 5
= 3 * 10
So, log 30
= log (3*10) = log 3 + log 10
= 0.4771 + 1
= 1.4771
and log √30
= 1/2 log 30
= 1/2 * 1.4771
= 0.73855

Answers- D) 4.4π & Area-44
1. To solve the first equation we must use the equation for find Circumfrence C=2πr. Our r is 2.2 so our equation would look as C= 2π2.2. Since 2 and 2.2 are whole numbers we can multiply them by one another and that gives us 4.4. So our final answer would be C= 4.4π or D)
2. The best way to solve for our area would be to cut the shapes straight down the middle. Now the two shapes will be 7x4 and 4x4. 7x4 is 28 and 4x4 is 16. To get our final answer we would add 28 and 16, which is 44. To show this one your work draw a line going straight down to cut the shapes into a square and a rectangle. (view source)

A metal bat is dropped from a hot air balloon and strikes the ground 6 seconds later. How high was the hot air balloon?
The balloon was flying at a height of 176.58 m .
The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:
Initial formula: v = u + at
The second formula is s = ut + 0.5at2.
The third formula is v2 = u2 + 2as.
Let t stand for the duration of the metal bat's flight, s for the height at which the hot air balloon was traveling, and u for the metal bat's initial vertical velocity since it is simply dropped.
Given: The metal bat took 6 seconds to reach the ground.
With t = 12 and u = 0, the second equation of motion gives us s = 0*t + 0.5*9.81*162 = 176.58 m.

Is this statement true or false?
0 x 5 = 5 x 0
The statement is true. Multiplication is commutative, which means that the order of multiplication does not affect the result.
The statement "0 x 5 = 5 x 0" is true because of the commutative property of multiplication. In multiplication, the order of factors does not change the result.
When we multiply 0 by 5, it equals 0 since anything multiplied by 0 is 0. Similarly, when we multiply 5 by 0, the result is still 0. Both expressions are equal to 0, confirming the commutative property.
In summary, 0 x 5 and 5 x 0 are interchangeable and yield the same result, proving the truth of the statement based on the fundamental property of multiplication.

Given:
a.) Each small box of paper weighs 50 pounds.
b.) Each large box of paper weighs 80 pounds.
c.) There were 4 more large boxes shipped than small boxes.
d.) The total weight was 1750 pounds.
Since the scenario is involving two types of boxes, we will be using two variables to represent each of them.
Let,
x = the total number of the small box of paper
y = the total number of the large box of paper
Let's now generate the system of equations that we will be using to able to solve the problem.
1st relationship: There were 4 more large boxes shipped than small boxes.
Putting this into equation, we get:
[tex]\text{ y = x + 4}[/tex]2nd relationship: The total weight was 1750 pounds.
For us to get the total weight, we will be adding the sum of the number of each box by the weight each box has.
We get,
[tex]\text{ 50x + 80y = 1750}[/tex]In summary:
Let x = the total number of the small box of paper
Let y = the total number of the large box of paper
System of equations:
a.) y = x + 4
b.) 50x + 80y = 1750

In three-dimensional space, a sphere is a collection of points that are all located at the same r-distance from a single point. The radius of the sphere is denoted by the letter r, and the given point is its center. The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin. A sphere is a solid shape that is round, without edges. Balloons, playing balls, and even light bulbs are examples of objects with sphere shapes.So, the formula for the volume of a sphere: V = 4/3πr³

The anti derivative of the function eˣ² is eˣ²/2x.
What is defined as the anti derivative?Derivatives are the inverse of antiderivatives. An antiderivative is a function that does the opposite of what a derivative does. There are many antiderivatives of one function, but they all take the shape of a function + an arbitrary constant. Indefinite integrals rely heavily on antiderivatives.An antiderivative, F, of the a function, f, is a function that may be differentiated to get the original function, f. In other words, an antiderivative is defined mathematically as follows: ∫ f(x) dx = F(x) + C, where C is the integration constant.The given function is; eˣ².
To find the anti derivative of the function, integrate the function with respect to x.
Let y = eˣ²
Integration of exponential function remains same but applying the chain rule, the derivative of the power of exponent comes at the denominator.
∫y. dx = ∫eˣ² .dx.
∫eˣ² .dx. = eˣ²/(d/dx)x²
∫eˣ² .dx. = eˣ²/2x

step 1
As you know before decimal the digits are said to be ones,tens, hundred so on and starts from left to right.
But after decimal it goes right to left and they are said ones,tenth,hundredth
step 2
so here it says 1 decimal place means ones means one digit after dot or point so its 2
The number rounded off to 1 decimal place is 1.2
what is rounding off a decimal number?Rounding is a process to estimate a particular number in a context. To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up. Rounding decimals refer to the rounding of decimal numbers to a certain degree of accuracy.
Given here, the number is 1.249 and thus the number rounded upto 2 decimal place is 1.25 and further rounding up the number to one decimal place we get 1.2
