We can do the following steps to solve the equation.
Step 1: We apply the distributive property. For this, the number outside the brackets is multiplied by everything that is inside the brackets.
Then, we have:
\(\begin{gathered} \frac{5}{4}(x-\frac{8}{5})=13 \\ \frac{5}{4}\cdot x-\frac{5}{4}\cdot\frac{8}{5}=13 \\ \frac{5}{4}x-\frac{5\cdot8}{4\cdot5}=13 \\ \frac{5}{4}x-\frac{8}{4}=13 \\ \frac{5}{4}x-2=13 \end{gathered}\)Step 2: We add 2 from both sides.
\(\begin{gathered} \frac{5}{4}x-2=13 \\ \frac{5}{4}x-2+2=13+2\rbrack \\ \frac{5}{4}x=15 \end{gathered}\)Step 3: We multiply by 4 from both sides.
\(\begin{gathered} 4\cdot\frac{5}{4}x=15\cdot4 \\ 5x=60 \end{gathered}\)Step 4: We divide by 5 from both sides.
\(\begin{gathered} \frac{5x}{5}=\frac{60}{5} \\ x=12 \end{gathered}\)Therefore, the value of x is 12.

The blue object (D) has been rotated 270° clockwise about the point (1, 2). Which is the correct image?
Answers
The correct image include the following: B. Green: image A.
What is a rotation?In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
By applying a rotation of 270° clockwise about the point (1, 2) to the coordinate of the vertices of blue block D, the coordinate the vertices of of its image would be located at the position of the Green: image A.
In this context, we can reasonably infer and logically deduce that Green: image A is the correct transformed shape.

A coin is flipped 50 times and shows heads on 22 occasions. Calculate the relative frequency of the coin showing heads.
0.44
22
50
0.5
Answers
Answer:
The relative frequency of a coin showing heads is calculated by dividing the number of heads by the total number of coin flips.
In this case, the number of heads is 22 and the total number of coin flips is 50.
So the relative frequency of the coin showing heads is:
22/50 = 0.44
Therefore, the correct answer is 0.44.

The area of a square garden is 100 square meters.
a. Find the length of each side of the garden.
? m area = 100 m2
b. Find the perimeter of the garden.
Please help
Answers
Answer:
a. The length of each side of the garden is 10 m.
b. The perimeter of the garden is 40 m.
Step-by-step explanation:
A square is a regular polygon with four sides. The area of a square is given by the formula
\(Area = width \cdot height\)
But since the width and height are by definition the same, the formula is usually written as
\(Area = s^2\)
where s is the length of one side.
a. To find the length of each side of the garden we know that the area is 100 \(m^2\) applying the area formula and solving for s, the length of one side, we get that
\(100=s^2\\\\s^2=100\\\\\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\s=\sqrt{100},\:s=-\sqrt{100}\)
The length can't be negative. Therefore, \(s=\sqrt{100}=10\)
b. In the case of a square, all four sides are the same length, so the perimeter is four times the length of a side. Or as a formula:
\(Perimeter = 4s\)
where s is the length of any one side.
We find that the length of each side is 10 m. Therefore, the perimeter is
\(Perimeter = 4s\\\\Perimeter =4 \cdot 10 = 40 \:m\)

Answers
Answer:
The second circle graph, labeled "New York City visitor's transportation, with five sections labeled walk 40 percent, bicycle 8 percent, car service 15 percent, bus 10 percent, and subway 27 percent" correctly represents the data in the table.
Step-by-step explanation:
The correct circle graph would have five sections labeled walk, bicycle, car service, bus, and subway, with each section representing the percentage of visitors who used that mode of transportation.
To find the percentage for each mode of transportation, we need to calculate the total number of visitors:
Total number of visitors = 120 + 24 + 45 + 30 + 81 = 300
Now we can calculate the percentage of visitors for each mode of transportation:
Walk: 120/300 x 100% = 40%
Bicycle: 24/300 x 100% = 8%
Car Service: 45/300 x 100% = 15%
Bus: 30/300 x 100% = 10%
Subway: 81/300 x 100% = 27%
Therefore, the correct circle graph would have the following sections and percentages:
Walk: 40%
Bicycle: 8%
Car Service: 15%
Bus: 10%
Subway: 27%
Answer: New York City visitor's transportation, with five sections labeled walk 80 percent, bus 16 percent, car service 30 percent, bicycle 20 percent, and subway 54 percent

In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. We denote the similarity of triangles here by ‘~’ symbol.
Answers
Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.
If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures. Consider a hula hoop and the wheel of a cycle, the shapes of both these objects are similar to each other as their shapes are the same.
Triangle is a three-sided polygon. The condition for the similarity of triangles is;
i) Corresponding angles of both the triangles are equal, and
ii) Corresponding sides of both the triangles are in proportion to each other.
Properties of the triangle:
1-Both have the same shape but sizes may be different
2-Each pair of corresponding angles are equal
3-The ratio of corresponding sides is the same

The angle θ = 90° is not a solution to trigonometric equation sin 2θ = 1. (Right choice: A)
How to solve a trigonometric equation
In this problem we must determine what angle is not a solution of a given trigonometric equation. The solution set is found by means of algebra properties and trigonometric formulas:
sin 2θ = 1
2θ = 90° + 360° · i, where i is a whole number.
θ = 45° + 180° · i
According to this expression, θ₁ = 45°, θ₂ = 225° and θ₃ = - 135° are solutions to this equation. θ = 90° is not a solution of sin 2θ = 1.

The probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 0.125 or 12.5%.
To find the probability that Greg winds up wearing the white shirt and tan pants while getting dressed in the dark, we need to find out all the possible outfit options. According to the question given, first we nned to find out number of outfit combinations possible.
Total number of Outfit Combinations:
There are 4 shirts: a white one, a black one, a red one, and a blue one and also two pairs of pants, one blue and one tan. So, total number of possible outfit combinations would be 4 * 2 = 8.
No of favourable options:
As given in the question, Greg wears white shirt and tan pants. There is only one white shirt and one tan pant. So, number of favourable options would be only 1 .
Probability = Number of favourable outcomes/Total no. of combinations
Probability = 1/8
Probability = 0.125 or 12.5%
Therefore, the probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 0.125 or 12.5%.

The customer service department of a company found that the relationship between the number of minutes a customer spends on hold when telephoning and the customer's level of satisfaction on a 10-point scale can be approximated by the equation y=10−0.1x
, where x
is the number of minutes on hold and y
is the level of satisfaction. What does 0.1 represent in the equation?
Answers
In the equation y = 10 - 0.1x, the coefficient 0.1 represents the slope of the line.
Define slopeit represents the rate of change of y with respect to x, which is the amount by which y changes for every unit increase in x.
In this case, the slope is negative (-0.1), which means that as the number of minutes on hold (x) increases by 1 unit, the level of satisfaction (y) decreases by 0.1 units.
In other words, the longer a customer spends on hold, the lower their level of satisfaction is likely to be. The slope is a key parameter in the equation and provides valuable information about the relationship between the two variables.

Use the given zero to find the remaining zeros of the polynomial function.
P(x) = 2x3 − 5x2 + 6x − 2; 1 + i
Answers
Using the given zero . The three zeros of the polynomial function are 1 + i, 1 - i, 1/2, and 2.
What is the polynomial function?If 1 + i is a zero of the polynomial function P(x), then its conjugate, 1 - i, must also be a zero of the polynomial, since complex zeros of polynomial functions with real coefficients always come in conjugate pairs.
To find the remaining zero, we can use polynomial division or synthetic division to divide P(x) by (x - 1 - i)(x - 1 + i), which is the quadratic factor corresponding to the two known zeros:
2x^2 - 3x + 2
P(x) = --------------
(x - 1 - i)(x - 1 + i)
Now we need to solve for the roots of the quadratic factor 2x^2 - 3x + 2. We can use the quadratic formula:
x = [3 ± sqrt(9 - 4*2*2)] / (2*2)
= [3 ± sqrt(1)] / 4
= 1/2 or 2
