Step-by-step explanation:
1. Increase of 10% in price of shirt.
2. Decrease of 10% in price of shirt.
Hence- both amounts cancel out, therefore there is 0% change in price of shirt as both percentages cancelled out, or we can say nullified each other. Because they added the same amount to the item and then subtracted the same percent leading to no change.
What is the slope of this line?
Enter your answer as a whole number or a fraction in simplest form in the box.
Answer:
-1
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{4.4cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ \\are two points on the line.\\\end{minipage}}[/tex]

Cars under 25 mph / Total Number of Cars
Cars under 25 mph:
I count 42 I think.
Total Number:

42 / 50 = .84
.84 * 100 = 84%
So, 84% of cars are moving below the speed limit.
The width of a claroom i 4meter le than the length. It area i 45cm*45cm. Find the dimenion of the claroom
The dimensions of the classroom are a width is 5 m and a length is 9 m.
We have been given that the width of a classroom is 4m less than the length its area is 45m², then.
L= 4 + W
Area = 45, so
L x W = 45
Now substituting the value of L, we get.
(4+W) W=45,
Now simplifying this we get.
4W + W² =45
W² + 4W - 45 = 0, this is a quadratic equation
Now solving this we get the factors 9 and -5,
(W+9) and (W-5) = 0
Thus, W= -9 or W= 5, since the width cannot be negative,
So, it is width = 5
So, length = 9 m
In physics and arithmetic, the dimension of a mathematical space (or item) is informally defined as the minimal range of coordinates to specify any factor within it. therefore, a line has a dimension of one (1D) due to the fact handiest one coordinate is wanted to specify a factor on it – for instance, the point at 5 on more than a few lines. A floor, together with the boundary of a cylinder or sphere, has a size of two (2d) because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the floor of a sphere. A two-dimensional Euclidean area is a -dimensional area on the aircraft. The internal of a dice, a cylinder, or a sphere is 3-dimensional (3-d) due to the fact 3 coordinates are had to find a factor inside these spaces.
In classical mechanics, area and time are distinct classes and seek advice from absolute space and time. That theory of the sector is a four-dimensional space however not the only one that was discovered as essential to explain electromagnetism. The four dimensions (4D) of spacetime encompass activities that are not really described spatially and temporally, however as a substitute are acknowledged relative to the movement of an observer. Minkowski's area first approximates the universe without gravity; the pseudo-Riemannian manifolds of fashionable relativity describe spacetime with depend and gravity. 10 dimensions are used to describe the superstring principle (6D hyperspace + 4D), eleven dimensions can describe supergravity and M-principle (7D hyperspace + 4D), and the kingdom-space of quantum mechanics is an infinite-dimensional feature area.

36 is a multiple of two numbers added together without a common factor.
What is a common factor?When a number is exactly divided by a divisor, that divisor is known as a factor of that number.
Alternatively, a factor of a number is an exact divisor of the provided number.
A number's factors are either less than or equal to the supplied number; they cannot be bigger. Every number is a factor of itself, and the common factor of all numbers is 1.
A number can be divided exactly by numerous divisors if it is a multiple of the divisor, therefore when we determine the factors of two or more numbers, we discover that some factors are common. As an illustration, the factors of 35 are 1, 5, 7, 35 while those of 45 are 1, 3, 5, 9, 15, 45. 1 and.

Solve x for this diagram
Answer:
x = 20
Step-by-step explanation:
the 3 unknown angles form a right angle and sum to 90° , that is
x + 2x + x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Answer:
x = 20°
Step-by-step explanation:
From the picture we know that x + 2x + x + 10 = 90°
x + 2x + x + 10 = 90
4x = 80
x = 80 : 4
x = 20°

What is the order from least to greatest of the following: 0.8, −0.1, 1.1, and −1.5?
Answer:
I think -1.5 -0.1 0.8 1.1
Answer:
-1.5 || -0.1 || 0.8 || 1.1
Explanation:
Since it is from least to greatest, let's compare the 2 negative numbers -1.5 and -0.1.
-1.5 has a 1 in its first place while -0.1 has a 0. This means that -1.5 is smaller because the further a number is on the negative number line the smaller it is.
So, -1.5 is the smallest, then -0.1.
-1.5 || -0.1
Now we compare the 2 positive numbers 0.8 and 1.1.
0.8 has a 0 in its first place and 1.1 has a 1 in its first place. Because the numbers are positive, the number with the biggest digit in in front of the decimal is greater.
So, in this case 1.1 is greater than 0.8.
0.8 || 1.1
In order it is:
-1.5 || -0.1 || 0.8 || 1.1
One thousand tickets are sold at $5 each. One ticket will be randomly selected and the winner will receive a color television valued at $375. What is the expected value for a person that buys one ticket?
Multiple choice:
-$4.62
-$1.00
$1.00
$4.62
Answer:
Hope this helps, Good Luck! :)
Step-by-step explanation:
EV = - + prob(win)*win
= -5 + 1/1000 * 375
= -4.62
The requried, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.
To calculate the expected value, we need to consider the probability of winning the color television and the corresponding value of the prize. We can then subtract the cost of buying the ticket to find the expected value.
Given:
Cost of one ticket = $5
Value of the color television (prize) = $375
Number of tickets sold = 1000
The probability of winning the color television is 1 out of 1000, as only one ticket will be selected out of the total 1000 tickets sold.
Expected Value (EV) = (Probability of winning * Value of prize) - Cost of the ticket
EV = (1/1000 * $375) - $5
EV = $0.375 - $5
EV = -$4.625
Rounded to two decimal places, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.

Define the term combination?A combination is indeed a selection of all or a portion of a group of items, regardless of the sequence in which the items are chosen.The formula for the combination is-
ⁿCr = n!/r!(n - r)!
We are wondering in how many distinct options there are to choose 4 subjects out of 20;
n = 20
r = 4.
Sequence is not important because the topics can be arranged in any order and still form the same group, hence we must use a combination:
Review the combination's definition:
²⁰C₄ = 20!/4!(20 - 4)!
²⁰C₄ = 20!/4!16!
²⁰C₄ = 4845

Given that the first two sides of a triangle are 8 cm and 10 cm in length, the third side's range of potential lengths will be [2,18].
What is range?When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself. The difference between the highest and lowest values for a given data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range can also be thought of as the distance between the highest and lowest observation.

Since the triangles are similar, the side lengths are proportional. One way we can solve this is by finding the scale factor for the triangle on the left to the triangle on the right. We can use the two corresponding sides that we know.
Let x = the scale factor
385x = 175 Divide both sides by 385
x = [tex]\frac{175}{385}[/tex] Simplify by dividing the numerator and the denominator by 35
x = [tex]\frac{5}{11}[/tex]
