Answer:
A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x ∠B = 38° + x∠A and ∠B are complementaryIf complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13
The value x form the given complementary angles is 13°.
Given that, m∠A = 26° + x and m∠B = 38° + x.
What are complementary angles?Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).
Here, m∠A + m∠B =90°
⇒ 26° + x+38° + x =90°
⇒ 2x+64° =90°
⇒ 2x =90°-64°
⇒ 2x =26°
⇒ x = 13°
Therefore, the value x form the given complementary angles is 13°.

What is the value of y in the equation y = 1/4 x divided by 2 when x =32
The value of y is 16 when x = 32 for equation y = (1/4)x divided by 2.
What is an equation?Mathematical expressions with two algebraic expressions on either side of the equals (=) sign are called equations. It displays how the expressions on the left and right sides are equally related. We have LHS = RHS in any mathematical equation. Equations can be solved to get the value of an unknown variable that represents an unknown quantity. If there is no "equal to" symbol, a statement is not an equation.
The given equation is
y = 1/4 x divided by 2
So,
y = ((1/4)x)/ 2
y = (2/4) × x
Put x = 32
y = 2/4 ×32
y = 2 × 8
y = 16

The amount that her clothes weigh more than her books would be = 57kg
The amount for the shipping cost for her school would be = 5600+25400 = $31000
What is postal service?Postal service is the type of service that helps.in the delivery of goods from one location to another when the goods are properly registered.
The mass of Moya's books = 70 kilograms
The mass of Moya's clothing = 127 kg
The difference between the bothe masses = 127 - 70 = 57kg
The cost per kg for books = $80 per kg
The cost per kg of clothing = $200
Therefore, the amount for the shipping cost for her school would be = (70×80) + (127 ×200)

Solve x^3 + x - 4 = 0, leaving your answers correct to 2 decimal places.
The solution to the equation x³ + x - 4 = 0 is x = 1.38
How to determine the solution to the equationFrom the question, we have the following parameters that can be used in our computation:
x^3 + x - 4 = 0
Express the exponents as proper superscript
So, we have the following representation
x³ + x - 4 = 0
Next, we solve the equation using a graph
i.e. we plot the graph of x³ + x - 4 = 0
See attachment for the graph of x³ + x - 4 = 0
The points where the graph of x³ + x - 4 = 0 crosses the x-axis are the solution
In this case, the point is 1.38
Hence, the solution is x = 1.38

What is the length of the missing leg?
Answer:
a = 12
Step-by-step explanation:
Formula:
a² + b² = c²
Given:
b = 9
c = 15
Finding a:
a² + b² = c²
a² = c² - b²
a² = 15² - 9²
a² = 225 - 81
a² = 144
[tex]\sqrt{a^2} =\sqrt{144}[/tex]
a = 12
Answer:
12
Step-by-step explanation:
To solve this, use the pythagreons theorm:
a^2+b^2=c^2
A and B are the side lengths, while is the hypotenuse, which in this case is 15 meters.
So lets plug in our values and solve for the missing length:
9^2+b^2=15^2
Square all the values except for the unknown:
81+b^2=225
Subtract from both sides to get b alone:
b^2=144
Take the square root of both sides so b^2 becomes b:
b=12
So your answer is 12!

What is statistics. Explain?
The science of statistics focuses on creating and researching strategies for gathering, analysing, interpreting, and presenting empirical data.
Research in statistics finds application in almost all scientific domains, and research concerns in the various scientific fields inspire the creation of new statistical methods and theories. Statistics is a very interdisciplinary field. Statisticians use a range of mathematical and computational techniques while creating new approaches and researching the theory that supports such methods. Uncertainty and variation are two key concepts in the study of statistics. In science, as well as more generally in life, there are numerous circumstances where the result is unknown. Sometimes the uncertainty is caused by the fact that the result is still up in the air. Probability is a mathematical language that is used to talk about uncertain events, and it is crucial to statistics. There are numerous causes of variance that can affect any measurement or data collection attempt. By this, we indicate that the result would probably alter if the same measurement was repeated. The goal of statisticians is to comprehend and, whenever feasible, manage the sources of variation.

A square board is attached to a wall. The board is divided into four squares and each square is painted either black or white. In how many ways can the board be painted if we can rotate the given board about its center? The answer is not 14 or 16.
The board can be rotated in 4 different ways (0, 90, 180, 270 degrees) and each of the four squares can be painted in 2 different ways (black or white). Since we can rotate the board, the order in which the squares are painted does not matter, so we must divide by the number of ways to rearrange the squares. So, there are (2^4) / 4 = 6 ways the board can be painted when we take rotations into account.
How to calculate the Rotation rate?To calculate turnover, it is necessary to consider the departures and additions of people to the company in the period. Calculating turnover is quite simple: you need to add the number of admissions and the number of dismissals, then just divide by 2 and then divide by the total number of employees within your company.
