What is the distance?Generally, There is a concept referred to as distance that may be used to quantify, either quantitatively or qualitatively, the distance that separates two items or sites.
When speaking about physics or using the phrase in everyday language, "distance" may either refer to a literal measurement or an estimate based on a number of other parameters.
Both meanings are appropriate when discussing or using the term.
The progression of existence and events that occur in what seems to be an unstoppable order beginning in the past, continuing through the present, and moving into the future is what we refer to as time.
Time may be broken down into three distinct parts: the past, the present, and the future.

The factors of the given monomial are given below
What is a monomial?
A monomial is, broadly speaking, a polynomial with just one term in mathematics. There are two definitions of a monomial: A monomial, often known as a power product, is a product of powers of variables with nonnegative integer exponents, or a product of variables with repeats. The constant 1 is a monomial, which means that it is equivalent to the empty product and to for any variable x. If just one variable, x, is examined, a monomial is either 1 or a power xn of x, where n is a positive integer. If many variables, say x,y,z, are examined, each can be assigned an exponent, such that each monomial has the form xaybzc with a,b,c non-negative integers.

Find the approximate perimeter of the isosceles triangleAOPD. Round your answer to the whole number.
Answers
The perimeter of the given triangle is the sum of the following segments:
Perimeter = PD + DO + OP
based on the given graph, you have that the coordinates of the points PDO are:
P: (1,-6)
D: (4,3)
O: (7,-6)
use the following formula for the distance in between two points:
d = √((x2 - x1)²+(y2 -y1)²)
where (x1,y1) and (x2,y2) are two points on the cordinate system.
For segement PD you have:
PD = √((1-4)²+(-6-3)²) = √(100) = 10
For segemtn DO:
DO = √((4-7)²+(-6-3)²) = √(100) = 10
For segment OP:
OP = √((1-7)²+(-6+6)²) = √36 = 6
then, the perimeter of the triangle is:

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
With this in mind we conclude that:
There are 8 values in the data set which are greater than or equal to 20 and less than or equal to 29. This comes from the fact that we have to count how many leafs are in the stem 2.
There are 6 values in the data set which are greater than or equal to 10 and less than or equal to 19. This comes from the fact that we have to count how many leafs are in the stem 1.

a lab technician is tested for her consistency by taking multiple measurements of cholesterol levels from the same blood sample. the target accuracy has an average of 2.78 or less with a standard deviation of 1.17. if the lab technician takes 16 measurements and the variance of the measurements in the sample is 2.45, does this provide enough evidence to reject the claim that the lab technician's accuracy is within the target accuracy?
Answers
The proper test statistic has a value of 13.21.
As a result, repeated measurements of cholesterol levels from the same blood sample are taken to assess a lab technician's consistency.
The desired accuracy is a measurement variance of 2.78 or less. In the event that the lab technician conducts 16 measurements, and the sample's measurement variance is 2.45.
1) n=16 samples were used.
The desired accuracy is a measurement variance of 2.78 or less.
The sample's measurements' variance is 2.45 or less.
We list both the null and alternative hypotheses in response to the query.
Null hypothesis [tex]H_{0}[/tex] = [tex]var^{2} \geq[/tex] 2.78
Alternative hypothesis [tex]H_{a}[/tex] = [tex]var^{2} <[/tex] 2.78
We claim the alternative hypothesis.
2)Calculate the appropriate test statistic's value.
Using Chi-square,
X= ((n-1)(2.45)/(2.78)
X= 15(2.45)/(2.78)
X=36.75/2.78
X= 13.21
Therefore, The value of the appropriate test statistic is 13.21

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
given that :
Salesman A gets paid $300 a month plus $8 for every sale he makes :
let the no. of sales A made be : x
then, in order to make the same amount of salesman b we equate btoth the amount :
300 + 8x = 1500
8x = 1500-300
8x = 1200
x = 1200/8
x = 150
Therefore, the number of sales by A must be 150 to make the same amount of salesman b.

The perimeter of a square can be found using p=n+n+n+n
Answers
Answer: Well, yes. It's more like p = s + s + s + s. "S" = side. "P" = perimeter.
So, this is theoretically true if your variable for a side just happened to be "n".
You also put, "The perimeter of a square", A simpler way to put this is
P = s4 or in your case P = n4.
Because this shape is a square all side lengths and angles will be congruent, and therefore will all be the same (which is why we are able to multiply one side by four.)

A red ballon is 40 feet above the ground and rising at 2 ft/s. At the same time, a blue balloon is at 60 feet above the ground and descending at 3 ft/s. What will the height of the balloons be when they are the same height above the ground
Answers
Answer: 48 ft
Step-by-step explanation:
The height gap between the balloons is 60 -40 = 20 feet. That gap is being closed at the rate of 2 + 3 = 5 ft/s, so will be gone in ...
(20 ft)/(5 ft/s) = 4 s
At that time, the red balloon will have risen (2 ft/s)(4 s) = 8 ft to a height of ...
40 ft +8 ft = 48 ft
The blue balloon will have descended (3 ft/s)(4 s) = 12 ft to a height of ...
60 ft -12 ft = 48 ft
The balloons at at 48 ft when they are both the same height.
_____
Time and speed and distance are related by the formula you see on every speed limit sign:
speed = distance/time . . . . . . . (on the sign, it's "miles per hour")
or
time = distance/speed
or
distance = speed × time
_____
If you want equations, you can write them as ...
h = 40 +2t
h = 60 -3t
where h is the altitude the balloons have when they are at the same height, and t is the number of seconds it takes to get there.
We're only interested in h, so we can cancel t by multiplying the first equation by 3 and adding that to the second equation multiplied by 2:
3(h) + 2(h) = 3(40 +2t) +2(60 -3t)
5h = 120 +6t +120 -6t
h = 240/5 = 48 . . . . the height in feet at which the balloons are the same height

Given diagram is a solid prism of a triangular base. if the base of the prism is 480 cm cube. find its height .
Answers
Answer:
20 cm
Step-by-step explanation:
Given a prism with a right triangle base and a volume of 480 cm³, you want the height of the prism. The base has one side 8 cm, and hypotenuse 10 cm.
Base edgeThe missing edge of the right triangle base can be found using the Pythagorean theorem. It tells us the square of the hypotenuse is the sum of the squares of the other two sides:
b² = c² +a²
10² = 8² +a² . . . . . . . use given lengths
a² = 100 -64 = 36 . . . . subtract 8², simplify
a = 6 . . . . . . . . . . . . . length of side BC
Base areaThe area of the right triangle base is ...
A = 1/2bh . . . . . . . . b is the triangle base; h is its height
A = 1/2(6 cm)(8 cm) = 24 cm²
VolumeThe volume of the prism is ...
V = Bh . . . . . . . . . . . . . . . where B is the base area, and h is the height
480 cm³ = (24 cm²)h . . . use known values
h = 20 cm . . . . . . . divide by the coefficient of h
The height of the prism is 20 cm.
a 13-ft ladder rests against a vertical wall. if the bottom of the ladder slides away at 1 ft/s, at what rate is the top of the ladder sliding down the wall when the bottom of the ladder is 5 ft from the wall? g
Answers
The given situation can be solved using the differential equation and the top of the ladder slides downward at 0.417 ft/s.
Let:
x be the distance from the bottom of the ladder to the base of the wall
y be the distance from the top of the ladder to the bottom of the wall
When the ladder is still, apply the Pythagorean Theorem,
x² + y² = 13²
5² + y² = 13²
y² = 169 - 25 = 144
y = 12 ft
When the ladder slides, apply the differential equation:
x² + y² = 13²
2x . dx/dt + 2y . dy/dt = 0
Substitute x = 5, dx/dt = 1, y = 12
2 . 5 . 1 + 2 . 12 . dy/dt = 0
24 dy/dt = -10
dy/dt = -5/12 = - 0.417 ft/s
The minus sign indicates that the ladder is sliding downward.
