Zavier and Maria shared 70 books, Zavier had 2 more books than Maria, how many did Maria have?
Answer:
Zavier had 37 books, and Maria had 33 books
Step-by-step explanation:
You take 70 and divide it by 2 (cause you are only dividing the books up to maria and Zaviar); this will give you 35 books to each person EXCEPT Zavier has two more books to his pile, so you subtract two books from Marie and add it to Zaviers!
Which of the following numbers is the greatest? 16.007; 15.999; 15.99; 16.01
16.01 is the greatest number.
Numbers:
In everyday life, we use numbers. They are frequently known as numbers. We are unable to count things, dates, hours, money, etc. without numbers. These numerals are utilised for labelling and measurement purposes at various periods. The characteristics of numbers enable them to be used in arithmetic operations. Both verbal and quantitative representations are used to express these numbers.
Math teaches us about the various kinds of numbers there are. The types of numbers include natural and whole numbers, odd and even, rational and irrational, etc. In addition to this, the numbers are employed in numerous other contexts, including the creation of number series and arithmetic tables.

answer is option 2 : (1, 5) because:
when x = 1 , y should = 5:
[tex]\left \{ {{y=5x} \atop {y=4x+1}} \right.\\\\\left \{ {{y=5(1)} \atop {y=4(1)+1}} \right.\\\\\left \{ {{y=5} \atop {y=5}} \right.[/tex]

What is solving an equation?
Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution.
Consider, the given equation[tex]\frac{2}{3}x - 1=9-\frac{1}{6}x[/tex]
Add 1 on both sides,
[tex]\frac{2}{3}x -1+1 = 9-\frac{1}{6}x+1\\ \frac{2}{3}x=10-\frac{1}{6}x[/tex]
Add 1/6(x) to both sides,
[tex]\frac{2}{3}x + \frac{1}{6}x = 10 - \frac{1}{6}x+\frac{1}{6}x\\ \frac{5}{6}x = 10[/tex]
Multiply both sides by 6/5
[tex]\frac{5}{6}x (\frac{6}{5}) = 10(\frac{6}{5}) \\ x = 12[/tex]
Hence, the value of x is, x = 12.

The mean of a data set can be greater than any of the data sets
True or false and explain your reason.
The mean of a data set can be greater than any of the data sets is True.
The average is basically a model of the dataset. The most frequently occurring value. However, the mean value is often not one of the actual values observed in the dataset. The median can be larger or smaller than the mean of the distribution. So the given statement is wrong.
The mean is affected by outliers that do not influence the mean. Therefore, when the average distribution of data is skewed to the left, the mean is often less than the median. When the distribution is skewed to the right, the mean is often greater than the median. No matter what value we add to the set, the mean, median, and mode will shift by that amount but the range and the IQR will remain the same. The same will be true if we subtract an amount from every data point in the set.

Complete the two-way frequency table below, which shows the relationship between students who enroll in advanced algebra and physics in
particular high school. From a sample of 40 students, it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both. How
many students are enrolled in either algebra physics?
By making use of Set Theory, we calculate that a total of 38 students are enrolled in either physics or algebra.
Number of students taking algebra n(A)= 29
Number of students taking physics n(B)= 14
Number of students taking both subjects n(A∩B)= 5
So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)
The union of two sets is a set containing all elements that are in A or in B (possibly both).
As we know,
n(A∪B) = n(A) + n(B) - n(A∩B)
n(A∪B) = 29 + 14 - 5
n(A∪B) = 38
Therefore, A total of 38 students are enrolled in either physics or algebra.

Hence ΔKFG is similar to ΔFJH
Now using the property of similarity and proportion we can say that:
FG/FH = KF/JF
putting the values in the above proportion we get:

Question:
The local furniture store pays $ 60 for a sofa and sells it with a 30% markup. What is the selling price of the sofa?.
Solution:
Let the following data:
Base price = $60
30% of base price = $60 x 0.3 = $18
Then:
Selling price = $60 + $18 = $78.
Then, we can conclude that the correct answer is:
The selling price of the sofa is $78.

What is right angled triangle ?
A right triangle, also known as a right-angled triangle, an orthogonal triangle, or formerly a rectangled triangle, is a triangle with one right angle, meaning that its two sides are perpendicular. Trigonometry's foundation is the relationship between the right triangle's sides and other angles.
To find the value of x we will use the trigonometric formula
sin x = [tex]\frac{opposite}{hypotenuse}[/tex]
cos x = [tex]\frac{adjacent}{hypotenuse}[/tex]
tan x = [tex]\frac{opposite}{adjacent}[/tex]
cosec x = [tex]\frac{1}{sin x}[/tex]
sec x = [tex]\frac{1}{cos x}[/tex]
cot x = [tex]\frac{1}{tan x}[/tex]
As we know the value
hypotenuse = 14cm
opposite side = 8cm
∴ sin x = [tex]\frac{8}{14}[/tex]
= [tex]\frac{4}{7}[/tex]

Answer:
angle x =34.8°
Step-by-step explanation:
sinX=opposite/hypotenuse this means sin(θ) is the ratio of the opposite side to the hypotenuse
so, to solve this problem we have to find the value of sin X then we can get the value of X.
Let sin X = 8/14
=0.571
SO, X =sin-1(0.571) =34.8°
I have no idea how to solve this problem, could someone help me?△ABC∼△XYZ. Find the values of x and b (side lengths).
The symbol ∼ denotes similarity, that is, the triangles ABC and XYZ are similar. When two triangles are similar, they have the same shape but not necessarily the same size and their corresponding angles are the same. In turn, the corresponding sides of two corresponding triangles are in the same ratio. Graphically,
[tex]\frac{a}{a^{\prime}}=\frac{b}{b^{\prime}}=\frac{c}{c^{\prime}}[/tex]So to find x in the small triangle, you have
[tex]\begin{gathered} \frac{15}{10}=\frac{9}{x} \\ \text{ Multiply by x on both sides of the equation} \\ \frac{15}{10}\cdot x=\frac{9}{x}\cdot x \\ \frac{15}{10}x=9 \\ \text{ Multiply by }\frac{10}{15}\text{ on both sides of the equation} \\ \frac{10}{15}\cdot\frac{15}{10}x=9\cdot\frac{10}{15} \\ x=6 \end{gathered}[/tex]Finally, to find b in the large triangle, you have
[tex]\begin{gathered} \frac{15}{10}=\frac{b}{8} \\ \text{ Multiply by 8 on both sides of the equation} \\ \frac{15}{10}\cdot8=\frac{b}{8}\cdot8 \\ 12=b \end{gathered}[/tex]Therefore, the lengths of the sides x and b are

What is the Commutative Property of Multiplication?Commutative is derived from "commute," which means to move about or travel. The commutative property of multiplication states that the result is unaffected by the order in which the numbers are multiplied.
According to the commutative property, the result of addition or multiplication remains the same regardless of the sequence in which the numbers are added or multiplied. It should be noted that the commutative feature only applies to addition and multiplication, not to division or subtraction. As an illustration, the sum of 6 + 7 and 7 + 6 equals 13. Like 6 x 7 = 42, so does 7 x 6.

51% decay
Answer:
Step-by-step explanation:
This is decay, the rate of change is 49%
hope this helps!
The correct rate of change is B)49% decay.
What constant rate of change ?
A rate of change is constant when, at any given point along the function, the ratio of the output to the input remains constant. The slope is another name for the rate of change that is constant. A linear function's rate of change will be constant.
Here the given function is ,
=> h(x)=38(0.51)x.
For any exponential function in which the base is less than 1, it will be an exponential decay situation.
In this problem, the base is 0.51.
Then,The amount that the base is less than 1 ( i.e. 1 - base) . It represents the rate of change in decimal ,
=> 1-0.51 = 0.49
Converting into percentage => 0.49 *100 = 49%

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.
Answer:
perimeter is 7.5 units
Step-by-step explanation:
the sides of the regular polygon are the same length , then
5x - 6 = 3)x - 1)
5x - 6 = 3x - 3 ( subtract 3x from both sides )
2x - 6 = - 3 ( add 6 to both sides )
2x = 3 ( divide both sides by 2 )
x = 3 ÷ 2 = 1.5
then length of one side is
5x - 6 = 5(1.5) - 6 = 7.5 - 6 = 1.5 units
then perimeter = 5 × 1.5 = 7.5 units
