When written as a radical, the index of a expression x²/³ is 2.
What are defined as the radicals?A radical is the inverse of an exponent, which is represented by the symbol "√, also known as the root. It can be a square root or even a cube root, and the number preceding the symbol and otherwise radical is known as an index number and degree.To rewrite the expression x²/³ as a radical expression, we must first understand what such a radical expression is.
A radical expression is a form expression: ⁿ√x.
As, ⁿ√x = x¹/ⁿ
Thus the given expression x²/³ can be written in the above form as;
x²/³ = (³√x)²
Now, the obtained result (³√x)² is written in the radical form where (³√x) is a radical.
As, the expression (³√x) is raised to the 2 power, the index of the expression when the expression is written as x²/³ have a radical is 2.
As a result, the index of the expression x²/³ when rewritten as a radical is 2.

What is the percentage formula?
By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.The word percentage comes from the Latin term per centum, which means "by the hundred." In the 16th century, the Latin phrase made its way into English. Later, it was shortened to percent and ended with a period.Use the formula percent change
Percent change = [tex]\frac{New - old}{old} * 100[/tex]
= 70- 30/30 * 100

It takes the object about 26/49 minutes to travel 5 1/5 miles.
How long would it take the object to travel 5 1/5 miles?A mixed fraction is a non-integer that consists of a whole number and a proper fraction. An example of a mixed fraction is 1 1/2.
Speed measures how fast an object is moving with respect to time. Speed is the total distance travelled per time.
Speed = total distance / total time
In order to determine the total time it would take the object to travel the distance, divide the distance travelled by the speed.
Time = distance / speed

If a/b=c/d'' then a and d are the ____?_____
If a/b = c/d then a and d are the extremes.
Ratio is defined as the comparison of two quantities. The ratio between quantities a and b can be expressed as a : b or a/b.
example:
There are 3 girls for every 5 boys in a class. Then, the ratio of girls to boys is 3 : 5 or 3/5.
On the other hand, proportion is defined as the equality between two or more ratios.
a : b = c : d
Two ratios are equivalent if their cross-products are equal. Cross products are the products of the extremes and means. The 1st and and 4th terms of a proportion is called the extremes, while the 2nd and 3rd is the means of a proportion.

Use the values of a₁ and Sn to find the value of a n a₁=4 and S₄₀=6080 ; a₄₀
Using the values of the first term and the sum of the first 40 terms of the given series, a(40) = 300
Suppose we are given a series:
a(1) + a(2) + a(3) + ....+ a(n)
Then, the sum of the first n terms is given by:
S(n) = n/2 [a(1) + a(n)]
Parameters given in the problem:
a(1) = 4
S(40) = 6080
To find a(40), substitute n = 40, a(1) = 4, and S(40) = 6080 into the formula:
S(n) = n/2 [a(1) + a(n)]
S(40) = 40/2 [4 + a(40)]
6080 = 20 . [4 + a(40)]
Divide both sides by 20
304 = 4 + a(40)
Subtract 4 from both sides:

Find x and the measure of each side.

The value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11
We know that, in an isosceles triangle, any two sides of the triangle are equal and the angle opposite to these sides are equal in measure.
In this question, we have been given an isosceles ΔMNP with MN ≅ NP .
Also we have been given some statements about the sides of isosceles ΔMNP.
MN is two less than five times x.
We write above statement as mathematical expression.
MN = 5x - 2
NP is seven more than two times x.
We write above statement as mathematical expression.
NP = 7 + 2x
And PM is two more than three times x.
We write above statement as mathematical expression.
PM = 2 + 3x
As MN = NP
⇒ 5x - 2 = 7 + 2x
⇒ 5x - 2x = 7 + 2
⇒ 3x = 9
⇒ x = 3
So, the value of x is 3.
Now we find the measure of each side of triangle JKL
MN = 5x - 2
MN = 5(3) - 2
MN = 15 - 2
MN = 13
Now the side NP
NP = 7 + 2x
NP = 7 + 2(3)
NP = 13
And side PM would be,
PM = 2 + 3x
PM = 2 + 3(3)
PM = 11
Therefore, the value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11

If the labor force of 165 million people is growing by 1.2 percent this year, how many new jobs have to be created each month to keep unemployment from increasing?
0.165 million jobs must be created monthly to keep unemployment from increasing.
What is the labor force?The combined employed and unemployed population makes up the labor force. The labor force as a percentage of the civilian noninstitutional population is the labor force participation rate.The number of employed persons plus the number of jobless people seeking work is known as the labor force. 1 The unemployed who are not looking for work are not included in the labor pool. For instance, stay-at-home mothers, retirees, and students are not employed.An economy's labor force is calculated as the sum of employed and jobless citizens. As a result, the labor force can be calculated using the formula: labor force = employed population + unemployed population.All employees are included in the labor force, including persons looking for work who are unemployed and the companies who pay their workers. A job seeker would not be regarded as an employee even if she were included in the labor force.How many new jobs have to be created each month to keep unemployment from increasing?
The population of the labor force = is 165 million
Percentage increase of labor force in a year = 1.2 % of 165 million
Percentage increase in the labor force in a month 1.2 %/12=0.1 %= of 155 million
Jobs required to be created each month = population increase each month

If p( a,2a) Q(4,3) and distance between them is 10 units find the coordinates of p
The distance between the coordinates is 2+√19.
According to the question, the given problem can be solved by using the standard distance formula.
Now, the coordinate values are:
p(a, 2a); q(4, 3) and Distance = 10 units
Therefore, from the given parameters we can write:
x1 = a; y1 = 2a; x2 = 4; y2 = 3
Now,
Distance^2 = (x1 - x2)^2 + (y1 - y2)^2
Substituting the given values, we get:
Distance^2 = (4 - a)^2 + (3 - 2a)^2 = 16 +a^2 - 8a + 9 +4a^2 - 12a
100 = 25 + 5a^2 - 20a
5a^2 - 20a - 75 = 0
a^2 - 4a - 15 = 0
a = 2+√19
Hence, the distance between the coordinates is 2+√19.

1 A map has a scale factor of 1 : 24 000
The distance between two towns is 3.6 km.
How far will this be on the map?
The two towns will be 15 centimeters apart on the map.
Here, we are given that a map has a scale factor of 1:24 000.
This means that if the distance between two points on the map is say 1 meter then in reality, these two points will be 24,000 meters apart.
Now, we are given that two towns are 3.6 kilometers apart
That is in reality, they are 3.6 km away
Let them be x kilometers away on the map
The ratio of the distances on map and in real life must be equal to 1/24,000
⇒ x/3.6 = 1/24,000
x = 3.6/24,000
x = 0.00015 kilometers
