The square root contains two same numbers and the cubic root contains three same numbers.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The square root contains two same numbers and the cubic root contains three same numbers.
For an example:-
√9 = [tex]\sqrt{3\times 3}[/tex] = 3 as we can see in the example the value of the square root of 9 is 3 it consists of two threes in the roots.
∛27 = [tex]\sqrt[3]{3\times 3\times 3}[/tex] = 3 here we have found that 27 contains 3 times 3 so the cube root of 27 will be equal to 3.
Therefore square root contains two same numbers and the cubic root contains three same numbers.

Determine the measure of the indicated angle!
The measure of the angle PUT is 13 degrees and the measure of the angle PQR = 21 degrees
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have triangles shown in the picture.
In the first triangle SUT:
PU is bisecting the angle SUT:
The measure of angle PUT:
Angle PUT = Half of Angle SUT
= 26/2
= 13 degrees
In the triangle SQR:
Angle SQP = Angle PQR
Angle SQP = 21 degrees
Angle PQR = 21 degrees
Thus, the measure of the angle PUT is 13 degrees and the measure of the angle PQR = 21 degrees

Click for the picture of the question it’s a multiple choice, I don’t even know where to begin
Answer:
b - read explanation if you are confused for future problems
Step-by-step explanation:
Inverse variation is when x*y = k whereas direct variation (may come up in future problems) is when y = x*k
Remember that k is always a set value while x and y are values that can change
In this case y*x = k so k = 18 (since y is 9 when x is 2)
So when x = 8
8y = 18
y = 18/8 = 9/4

Step-by-step explanation:
A trader bought 30 baskets of pawpaw and 100 baskets of mangoes for 2450. she sold the pawpaw at a profit of 40% and the mangoes at a profit of 30%. if her profit on the entire transaction was 855, find the cost price of a basket of pawpaw and the selling price of 100 baskets of mangoes.
The cost price of pawpaw is 40 and the cost if the basket of mangoes is 1250.
How to calculate the price?Based on the information given, the equations to solve the question will be:
30p + 100m = 2450 .... i
1.3 × 40p - 30 p + 1.3 × 100m = 855 ..... ii
30p + 100m = 2450
12p + 30m = 855
Solving simultaneously, the price of pawpaw is 40 and the price of mango is 12.5.
Therefore, the cost of 100 basket of mangoes will be:
= 12.5 × 100
= 1250

what are the true statements
write and solve a proportion to complete the statement. Round to the nearest hundredth if necessary.
1. 6km ≈ ?mi
2. 2.5 L≈ ?gal
3. 90lb ≈ ?kg
pls help
Answer:
Step-by-step explanation:
Convert kilometer to miles:1 km = 0.62 mi
So, to convert 6 km to mi, multiply 6 by 0.62.
6km = 6* 0.62
= 3.72 mi
Convert liter to gallon:1 L = 0.26 gal
To convert 2.5 L to gallon, multiply 2.5 by 0.26.
2.5 L = 2.5 * 0.26
= 0.65 gal
Convert pound to kilogram:1 lb = 0.45 Kg
To convert 90 lb to Kg, multiply 90 by 0.45.
90 lb = 90 *0.45
= 40.5 Kg

The number of ways this can be done is 151200 if they choose 6 letters without replacement from 10 distinct letters.
What are permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Suppose we want to choose 6 letters without replacement from 10 distinct letters.
Number of letters = 10
Number of letters need to select = 6
Order is important.
A number of ways:
C(10, 6) = 10!/(10-6)!
= 10!/(4)!
= 151200

Answer:
C (The third answer). The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
This problem can be thought similarly to: (x-2)²
A common mistake would to make the x squared and the -2 squared like x²+4, however, the problem should be solved like (x-2)(x-2) which equals to: x² - 4x + 4
In this question, if you square root an expression like ±√(b²-4ac), you cannot just take the square root of b² unless it was (b²)(-4ac).
The terms can only be divided individually if they are either multiplied or divided, but cannot if they are added or subtracted.

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than 3 times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. What was the temperature of City A and City B on that day?
A) City A was 5: C. and City B was 4° C.
B) City À was 3° C, and City B was -1° C
C)City A was 8° C. and City 3 was -3° C.
D)City À was 5° C, and City 3 was -5° C.
Answer:
A) City A was 5°C and City B was 4°C
Step-by-step explanation:
let temperature of City A be x and City B be y
According to the conditions of the question
4x = 8 + 3y (first temperature)
x - 2y = -3 (second temperature)
x = -3 + 2y
4(x) = (-3 + 2y)×4
4x = -12 + 8y
But it's already given that 4x = 8 + 3y
So,
8 + 3y = -12 + 8y
8 + 12 = 8y - 3y
20 = 5y
y = 20/5
y = 4
That means City B temperature was 4°C
So Option A
If you want you can find x to find City A temperature

If the divisor is a decimal then you must multiply by a power of 10 to make it a whole number. Why is it important to multiply the dividend and the divisor by the same power of 10?
It is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.
Division of whole numbers
When the numerator and denominator of improper fractions are in whole number form, it makes the division a lot easier.
For example;
what is the simplest form of 0.1/0.2?
To obtain the simplest form of the above function, we multiple the numerator and denominator by 10.
= (0.1 x 10)/(10 x 0.2)
= 1/2
Note: introducing factor of 10 to both numerator and denominator has not changed the function.
Thus, it is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

What is the sum of the arithmetic sequence 3, 9, 15..., if there are 24 terms? (5 points)
There's a fixed difference of 6 between terms (9 - 3 = 6, 15 - 9 = 6, and so on). The first term of the sequence is 3, so the [tex]n[/tex]-th term is
[tex]3 + 6(n-1) = 6n - 3[/tex]
If there are 24 terms in the sum, then the last term is 6×23 - 3 = 135.
Let [tex]S[/tex] be the sum,
[tex]S = 3 + 9 + 15 + \cdots + 123 + 129 + 135[/tex]
Reverse the order of terms:
[tex]S = 135 + 129 + 123 + \cdots + 15 + 9 + 3[/tex]
If we add up the terms in the same positions, we get twice [tex]S[/tex] on the left side, while on the right side we observe that each pair of terms will sum to 138.
[tex]S + S = (3 + 135) + (9 + 129) + (15 + 123) + \cdots + (135 + 3)[/tex]
[tex]2S = 138 + 138 + 138 + \cdots + 138[/tex]
and since there are 24 terms in the sum, the right side is the sum of 24 copies of 138. In other words,
[tex]2S = 24 \times 138[/tex]
and solving for [tex]S[/tex] gives
[tex]S = \dfrac{24\times138}2 = \boxed{1656}[/tex]

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k. 3 1/3 -1/3 −3
This is about interpretation of graphs.
Option C is correct.
From the graph, we can see the 2 lines representing function f(x) and function g(x).
Now for us to find the value of x in g(x) = k⋅f(x), we need get a mutual x-coordinate where we can easily read their respective y-coordinate values.
We see that the best point for that is where x = -3.
For f(x), when x = -3, y = 1
For g(x), when x = -3, y = -3
we can rewrite them as;
x = -3, f(-3) = 1 and x = -3, g(-3) = -3
Let us plug in the relevant values into g(x) = k⋅f(x) to get;
-3 = k(1)
Thus; k = -1/3

solve 3(10)^x = 30,000
Step-by-step explanation:
We will need to use logs here...
First divide each side by 3
[tex]3(10)^x=30000[/tex]
[tex]10^x=10000[/tex]
Then take the log of each side
Keep in mind that [tex]log_{10} (10)[/tex] gets canceled out to leave x
[tex]log_{10} (10^x)=log(10000)[/tex]
Finally, log(10000) = 4 because [tex]10^4=10000[/tex]
[tex]x = 4[/tex]
Solve for x in the diagram below.
Answer:
x = 34
Step-by-step explanation:
A straight line is 180 degrees
We can sum angles to form a straight line
x+12 + 100 +x = 180
Combine like terms
2x+112 = 180
2x+112-112 = 180-112
2x = 68
Divide each side by 2
2x/2 = 68/2
x = 34
answer:
=x+12+100+x =180
=x+x+12+100=180
=2x+112=180
=2x=180-112
=2x=68
