Change 23 out of 25 to a percentage
This how we change 23 out of 25 to a percentage
The numerator of a question is the number that appears above the bar; in this case, the numerator is 23.
The denominator is the number beneath the bar, and in this question, it is 25.
To calculate the value of a fraction, divide the numerator by the denominator.
Therefore, we must divide 23 by 25.
23/25 = 0.92
To determine the percentage, multiply the outcome by 100.
The percentage value will be obtained by multiplying 0.92 by 100.
0.92 x 100 = 92%
As a result, 92% is the answer to the question.

cos^4x - sin^4x +1 = 2cos^2x
prove
Proved [tex]Cos^{4}x - Sin^{4}x + 1[/tex] = 2Cos²x
We will use the Pythagorean Theorem:
Sin²x + Cos²x = 1
from which we can get:
Sin²x = 1 - Cos²x
Also, note that the difference in the similarity of squares can be written:
A² - B² = (A - B)
We can use this with A = Sin²x and B = Cos²x as follows:
[tex]Sin^{4}x - Cos^{4}x[/tex]
= (Sin²x)² - (Cos²x)²
= (Sin²x - Cos²x) (Sin²x + Cos²x)
= Sin²x - Cos²x
= (1 - Cos²x) - Cos²x
= 1 - 2Cos²x
Now move the 1 and negative symbols to the left.
[tex]Cos^{4}x - Sin^{4}x + 1[/tex] = 2Cos²x

A man's taxable income is $3.060 If tax is paid at 12%. How much is the man's net income
A man's taxable income is $3060 if tax is paid at 12%, then the man's net income is $3477.27
The taxable income = $3060
The tax percentage = 12%
Income tax is the a type of tax impose on income generated by businesses and individuals by the government
Consider the net income as x
Then,
12% of the income = x×(12/100)
Therefore the equation will be
x - x×(12/100) = 3060
x(1-(12/100) = 3060
x(1-0.12) = 3060
0.88x = 3060
x = 3060/0.88
x = $3477.27
Hence, a man's taxable income is $3060 if tax is paid at 12%, then the man's net income is $3477.27

What is a line segment?A line segment can be defined as the part of a straight line that is being bounded by two different end points, and also contains all the points on the line between its endpoints.
From the information given, we have that line AD is a line with segments, line AB, line BC, line CD with B and C as the midpoints.
Given the points as;
AC = x + 23BD = 12BC = 14 + xAD = 26 + xWe have that;
AC + BC = AD
But line BD = 14 + x, we have;
Line AC = x + 23 - 14 + x
Line AC = 2x + 9
substitute the values into the equation
2x + 9 +12 = 26 + x
collect like terms
2x - x = 26 - 21
Add or subtract like terms

4. Find “a” so that the parabola y = ax² + 3x + 11 goes through the point (3,2).
Answer:
a = - 2
Step-by-step explanation:
since the point (3, 2 ) lies on the parabola, then it makes the equation true.
substitute x = 3, y = 2 into the equation and solve for a
y = ax² + 3x + 11
2 = a(3)² + 3(3) + 11
2 = 9a + 9 + 11
2 = 9a + 20 ( subtract 20 from both sides )
- 18 = 9a ( divide both sides by 9 )
- 2 = a
Answer:
a = -2
Step-by-step explanation:
Given quadratic equation:
[tex]y=ax^2+3x+11[/tex]
In order to find "a", substitute the given point on the curve (3, 2) into the equation and solve for a:
[tex]\begin{aligned}y&=ax^2+3x+11\\\textsf{Substitute $(3,2)$} \implies 2&=a(3)^2+3(3)+11\\2&=9a+9+11\\2&=9a+20\\2-20&=9a+20-20\\-18&=9a\\9a&=-18\\\dfrac{9a}{9}&=\dfrac{-18}{9}\\\implies a&=-2 \end{aligned}[/tex]
Therefore, the value of "a" so that parabola y = ax² + 3x + 11 goes through the point (3, 2) is:

Which number is located between 11 and 12 on a number line?
A.
√150
B.
√134
C.
√115
D.
√121
√134 is the number which is located between 11 and 12 on a number line.
What is a Number Line?A number line is a horizontal straight line on which real numbers are arranged in equal intervals. This line extends both sides at infinity.
Comparison and operations of numbers can be better explained using number lines.
Taking consecutive perfect squares of integers which lies above and below the given numbers on the number line and taking it's square root, we can find the answer.
The perfect squares below and above 150 are 144 = 12² and 169 = 13². So √150 lies in between 12 and 13.
The perfect squares below and above 134 are 121 = 11² and 144 = 12². So √134 lies in between 11 and 12.
The perfect squares below and above 115 are 100 = 10² and 121 = 11². So √115 lies in between 10 and 11.
The number 121 is itself a perfect square. √121 = 11.
Hence √134 is the number which lies in between 11 and 12.
