When converting to an equivalent value, the appropriate conversion factor must be utilized. To convert inches into feet, for example, the suitable conversion value becomes 12 inches equal to 1 foot.
What exactly does unit conversion imply?Unit conversion is indeed a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of important digits, and rounding.
According to the given data:The car gets 35 miles for each gallon of gas.
We need to calculate how many liters of petrol will be required for a 450-kilometer trip.
first converting km into miles:
1 km =0.621371 miles.
So,
450 km = 450 x 0.621371
= 279.61 miles.
Now we know that :
One gallon of gasoline will get you 35 miles.
So for 279.61 miles.
Let x be the number of liters of gasoline required to travel the distance.
So
x = 279.61 / 35
x = 7.98 gallons
Now in litters:
1 gallon = 3.78541litters
So,
7.98 * 3.7854 = 30.24
= 3.0 x 10¹ litter
As a result, 3.0 x 10¹ litter of petrol will be used for a 450-kilometer trip.

On a number line, suppose the coordinate of A is 0, and AR = 17. What are the possible coordinates of the midpoint of AR ?
Step-by-step explanation:
The coordinate of A is 0. It is given that AR = 17. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.
Point R is on Right side of A i.e. at coordinate 17
Point R is on Left side of A i.e. at coordinate -17
In both of these cases AR which is the distance from A to R will be 17.
So, if R is on Right side of A, the midpoint of AR would be:
0+17
÷ = 17/2 = 8.5
2
Or if R is on Left side of A, the midpoint of AR would be:
0-17
÷ = -17/2 = -8.5
2
Thus, the possible coordinates of the midpoint of AR are 8.5 and -8.5
A new car is purchased for $26, 000 and over time its value depreciates by one half
every 7 years. How long, to the nearest tenth of a year, would it take for the value of
the car to be $8, 800?
If the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.
Given that the cost of car is $26000 and it depreciates by one half every 7 years.
We are required to find the number of years after which the cost of car will reach $8800.
Because the method of depreciation is not given in question, so we will apply straight line method of depreciation.
Depreciation is the gradual or permanent decrease in the cost of asset due to passage of time and many factors.
Depreciation of 7 years=26000*R*7
13000=26000*R*7
R=13000/26000*7
=7.14%
The cost of car will be $8800,so the depreciation charged will be 26000-8800=$17200
17200=26000*7.14/100 *N
N=1720000/26000*7.14
=9.2652
Because it is slightly larger than 9 so we can approx it as 10 years.
Hence if the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.

In a statistics test, the class average is 76 with a standard deviation of 8. emmy is told that the z-score of her exam score is -1.50. what was emmy's actual score on the exam?
Emmy's actual score in the exam is 64.
What is the Z score of the population?A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values. Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score.
Given,
class average = 76
standard deviation = 8
Z- score = -1.50
The formula of Z-score is -
z = (x-μ)/σ
Where x is the actual score,
μ is the mean,
σ is the standard deviation.
Now putting the values in the formula we get,
-1.50 = (x- 76) / 8
⇒ on solving, we get x = 64
So the actual score of Emmy = 64

In the diagram below of triangle LMN, O is the midpoint of LN and P is the midpoint of MN. If OP = 31 - 2x, and LM = 38 + 4x, what is the measure of LM?
Answer: LM= ?
If O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, then the measure of LM = 88
As per the question statement, Triangle LMN where O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, we are supposed to find the measure of LM.
As O is the mid point of LN and P is the midpoint of OP the using the Mid point theorem, we can say that in Triangle LMN
[tex]OP=\frac{LM}{2}[/tex]
Substituting values,
[tex]31-2x=\frac{38+4x}{2} \\2(31-2x)=38+4x\\62-4x=38+4x \\8x = 100\\x=12.5[/tex]
LM = 38 + 4x
[tex]LM = 38 + 4(12.5)\\LM=38 + 50\\LM=88[/tex]

If x - 4y = -10 and 2x + 9y= -3 are true equations, what would be the value of 3x+5y?
The value of the expression 3x + 5y will be 47.
How to calculate the equation?It should be noted that an equation is used in Mathematics to show the relationship the exist between different variables.
The given equations are:
x - 4y = -10 ...... i
2x + 9y= -3 ....... ii
Multiply equation i by 2
Multiply equation ii by 1
2x - 8y = -20 ...... iii
2x + 9y = -3. ..... iv
Subtract equation iv from iii
(2x - 2x) (-8y - 9y) = (-20 + 3)
-17y = -17
Then, we have to divide by the coefficient.
y = -17/-17
y = 1
Since x - 4y = -10.
We will then put the value of y = 1 into the equation
x - 4(1) = 10
x = 10 + 4
x = 14
Therefore, 3x + 5y will be:
=3(14) + 5(1)
= 42 + 5
= 47.

Find the value of the variable and Y Z if Y is between X and Z.
X Y=11 d, Y Z=9 d-2, X Z=5 d+28
For the given line segment, the value of variable d is 2 units and the value of YZ is 16 units.
Given that, Y is between X and Z.
We need to find the value of the variable and YZ.
What is a line segment?A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.
Given that, XY=11d, YZ=9d-2, XZ=5d+28
Here, the line segment XZ is sum of XY and YZ
That is, XZ=XY+YZ (∵Y is between X and Z)
⇒5d+28=11d+9d-2
⇒5d+28=20d-2 (Add like terms that is 11d+9d=20d)
⇒20d-5d=28+2
⇒15d=30
⇒d=2
So, YZ=9d-2
=9×2-2=18-2

What is the length of one side if the area of a square is 16 m²
Answer:
s = 4 m
Step-by-step explanation:
the area (A) of a square is calculated as
A = s² ( s is the side length )
given A = 16 m² , then
s² = 16 ( take square root of both sides )
s = [tex]\sqrt{16}[/tex] = 4 m
Answer:
4m
Step-by-step explanation:
All the sides of a square are equal lengths. So 2 numbers that are the same must equal 16m^2.
A number times itself is known as a square number. The value of this square number is 16 m².
It can be shown like this:
a²= 16 m² or a×a = 16 m²
The reverse of squaring numbers is square root. To find the value of one side you can do √16. √16 = 4. We can check this by substituting (replacing) 4 in the place of 'a' to see if the answer is 16.
a×a = 16 m²
4 × 4 = 16
Therefore, the length of one side of the square equals to 4m.

you choose, at least one marble is guaranteed to be blue. Is it
possible to figure how many blue marbles are in the jar? If so,
how
many are there?
The number of blue marbles in the jar are 8.
Given, the total number of marbles in the jar = 24.
therefore, total number of all possible outcomes = 24.
Let the number of green marbles in Jar be x.
therefore, the number of favourable outcomes = x.
The probability that the marble drawn is green = x/24
But we have the probability of drawing a green marble = 2/3
x/24 = 2/3
3x = 2 (24)
x = 16
Thus , the number of green marbles in the jar = 16
The number of blue marbles = 24 - 16 = 8
