Answer:
2/3
Step-by-step explanation:
Let x be number
Multiply by 2 = x * 2
Now, divide by 3 = 2x ÷ 3 = [tex]\frac{2x}{3}[/tex]
So, this is same as multiplying 'x' by [tex]\frac{2}{3}[/tex]

What is the vertex of the graph of the function below?
y= x2 - 10x + 21
O A. (5,-4)
B. (3,0)
O C. (5,0)
OD. (3,-4)
Answer:
Step-by-step explanation:
A. (5,-4)
The vertex of the graph of the function is (5,-4).
The answer is option A.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the vertex of the function y = x² - 10x + 21,
We can use the formula:
x = -b/2a
where a is the coefficient of the x² term, b is the coefficient of the x term, and x is the x-coordinate of the vertex.
In this case,
a = 1 and b = -10, so:
x = -(-10)/(2 x 1) = 5
To find the y-coordinate of the vertex, we can substitute x = 5 into the function:
y = (5)² - 10(5) + 21 = -4
Therefore,
The vertex of the graph of the function is (5,-4).

Joanne signed up for 24 dancing lessons she took 3/4 of the by April and 1/5 of them by May .What part of dancing lesson did she take?
Answer:
[tex]Part = \frac{19}{20}[/tex]
[tex]Lessons = 23[/tex]
Step-by-step explanation:
Given:
[tex]Dancing\ Lessons = 24[/tex]
[tex]April = \frac{3}{4}[/tex]
[tex]May = \frac{1}{5}[/tex]
Required:
Determine the part she took
To solve this, we simply add up the part she took in April and May.
[tex]Part = \frac{3}{4} + \frac{1}{5}[/tex]
Take LCM
[tex]Part = \frac{15 + 4}{20}[/tex]
[tex]Part = \frac{19}{20}[/tex]
Hence, she took [tex]\frac{19}{20}[/tex] of the dancing lesson.
However, to calculate the number of lesson.
We have to multiply [tex]\frac{19}{20}[/tex] by the total dancing lessons.
[tex]Lessons = \frac{19}{20} * 24[/tex]
[tex]Lessons = \frac{19* 24}{20}[/tex]
[tex]Lessons = \frac{456}{20}[/tex]
[tex]Lessons = 22.8[/tex]
[tex]Lessons = 23[/tex] ---- Approximated

Suppose Borman earned $148,000 last year. She calculates her self-employment tax by multiplying
$148,000 by 15.3%, which equals $22,644. Is Borman correct? Briefly explain.
Answer:
Yes Borman is correct.
Step-by-step explanation:
Borman moved the decimal point 2 spaces to the left which gave her 0.153
Then she multiplied that by $148,000 to get 15.3% of it which would give her $22,644 so therefore, she is correct.
evaluate each expression if m equals 3 and n equals 7, 3mn is?
Answer:
63
Step-by-step explanation:3(3)(7)=63
Answer: 3 x 3 x 7 = 63
Step-by-step explanation: I am not sure if this is what you are asking but when a number and a variable and next to each other without any spaces it means that you should multiply them, so, 3 x m is just 3 x 3. Expanding on this, if 3 x 3 x n is equal to 3 x 3 x 7 then you can just multiply 3, 3, and 7 for a total of 63.

The simplified form of 3√(512) using radical is 48√(2).
To simplify √(512), find the prime factorization of 512.
Prime factorization of 512:
512 = [tex]2^9[/tex]
Now, rewrite the square root as follows:
√(512) = √[tex](2^9)[/tex]
Next, use the property of square roots that states √(a * b) = √(a) * √(b):
√[tex](2^9)[/tex] = √([tex]2^8 * 2)[/tex]
= √[tex](2^8) * \sqrt(2)[/tex]
Since √[tex](2^8)[/tex] is equal to [tex]2^4[/tex] then
√(512) = [tex]2^4[/tex] * √(2)
Finally, simplify √(2) as it is not a perfect square:
√(512) = [tex]2^4[/tex]* √(2)
= 16 * √(2)
So, the simplified form is 48√(2).

dennis estimated the width of the space he has in his kitchen to fit a new refrigerator to be 36 inches. the actual width is 33 inches. what is the approximate percent error?
Answer:
8%
Step-by-step explanation:
Given the following data;
Experimental value = 36 inches
Theoretical value = 33 inches
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Substituting into the equation, we have;
[tex] Percent \; error = \frac {33 - 36}{ 36} *100[/tex]
Note: we would ignore the negative sign.
[tex] Percent \; error = \frac {3}{ 36} *100[/tex]
[tex] Percent \; error = 0.833 *100[/tex]
Percent error = 8.33 ≈ 8%
