What does a square have in common with a rectangle?
Each squares and rectangles are a form of quadrilateral, with four inner angles that are both 90 degrees, and opposite sides that are parallel to one another.
Are a square and a rectangle usually similar?
As a result, every square is a rectangle since it is a quadrilateral with right angles at each of its four corners. But not all rectangles are squares; for a shape to be a square, all of its sides must be the same length.
What is a rectangle, exactly?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.
The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.

Give a short note on triangle?A triangle is a three-sided polygon that is defined by three points in a plane, called its vertices. The three sides of a triangle are also called edges, and are connected by three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles, including:
Right triangle: has one angle of 90 degrees.Acute triangle: all three angles are less than 90 degrees.Obtuse triangle: has one angle greater than 90 degrees.Isosceles triangle: has two sides of the same length.Equilateral triangle: has three sides of the same length.Triangles are fundamental in mathematics and are used in many areas such as geometry, trigonometry, and engineering.
In a triangle, the measure of an angle is related to the lengths of the sides opposite and adjacent to it by the formula:
c = a/sin C
Given that c = 75 cm and mm∠C = 13°, we can use this formula to find the length of a:
a = c*sin C
where C is in radians.
a = 75 * sin(13°) = 75 * 0.2225 = 16.7 cm
Also, we know that the sum of the angles in a triangle is always 180°, so we can use that information to find the measure of angle A.
mm∠A = 180 - (mm∠B + mm∠C) = 180 - (154 + 13) = 180 - 167 = 13°
Therefore, using the Law of Sines, we can find the value of a.
[tex]\frac{a}{sin A}[/tex] = [tex]\frac{b}{sin B}[/tex] = [tex]\frac{c}{sin C}[/tex]
a = [tex]\frac{c*sin A}{sin C}[/tex]
a = [tex]\frac{75*sin(13^{0}) }{sin(154^{0}) }[/tex]
Now, you can use a calculator or a table of trigonometric values to find sin(13°) and sin(154°) and substitute them in the above equation to find the length of a. To the nearest tenth of a centimeter, a is approximately 18.6 cm.

To rent a certain meeting room, a college charges a reservation fee of $41 and an additional fee of $7.30 per hour. The history club wants to spend less than $92.10 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use for the number of hours the meeting room is rented, and solve your inequality for .
Answer:
Step-by-step explanation:
first we subtract 92.1 from 41 which gives us 51.1 now we want to see how many hours we can keep the room for while staying under 91.1 so we divide the value of 51.1(as we have to first pay the fee of $41) by 7.3 as that is the amount they are charging per hour(51.1/7.3) which gives us 7 so we can rent the roof for 7 hours max or just for 1,2,3,4,5 or 6 hours

Rachel's non-brokerage fee-related closing costs can be calculated by subtracting the brokerage fee from her total closing costs.
Since the brokerage fee was 6%, the fee comes out to be $1,105.20. To calculate the non-brokerage-related closing costs, subtract $1,105.20 from the total closing costs of $18,427, which yields a total of $17,321.80.
18427-1105.20=17321.80
This is the amount of non-brokerage fee-related closing costs that Rachel paid for her home. Rachel's net gain from the sale of her home was $230,063, which is the difference between the sale price of her home and the total closing costs, including the brokerage fee.

Akio draws a graph to record the distance he rides on a long bike ride. What is the slope of the line for the first two hours? What is the slope of the line for all five hours? What does the slope mean in this situation?
Answer:
Below
Step-by-step explanation:
To find the slope of a line, we use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, if Akio recorded the distance he rode on his bike ride in hours, the slope of the line for the first two hours would be the change in the y-coordinates (distance) divided by the change in the x-coordinates (time) between those two points.
To find the slope of the line for all five hours, we will need to know the specific coordinates of all five points, otherwise, it's impossible to calculate the slope.
The slope of a line represents the rate of change in the y-coordinates (distance) per unit of change in the x-coordinates (time). In this situation, the slope represents Akio's speed, since the change in distance is divided by the change in time. A positive slope indicates an increase in distance over time, which means Akio is getting faster, whereas a negative slope indicates a decrease in distance over time, which means Akio is getting slower.
It's worth noting that a slope of zero would mean that there is no change in distance over time, which would mean that Akio isn't moving.

Explain mean, median, mode briefly?In statistics, the mean, mode, and median are three measures of central tendency that describe a set of numerical data.
The mean is the average of a set of numbers, calculated by adding up all the values and dividing by the number of values. For example, if a set of data contains the values {1, 2, 3, 4, 5}, the mean is (1 + 2 + 3 + 4 + 5) / 5 = 3.
The mode is the value that appears most frequently in a set of data. For example, if a set of data contains the values {1, 2, 2, 3, 4, 4, 4, 5}, the mode is 4, because it appears three times, which is more than any other value.
The median is the middle value in a set of data when it is ordered in ascending or descending order. For example, if a set of data contains the values {1, 2, 3, 4, 5}, the median is 3, because it is the middle value. If there is an even number of values, then the median is the average of the two middle values.
It is important to note that different sets of data may have different measures of central tendency, and sometimes none of these measures may be appropriate.
Measures of central tendency are used to summarize and describe a set of data. The most common measures of central tendency are the mean, median, and mode.
1. Mean:
• Mean for June 2006: (508+435+538+913+367+033+254+240+137+022+160+548+260+458+358+035+222+879+136+371+127+586+201+316)/22 = $345,909
• Mean for June 2005: (422+843+469+588+245+803+199+409+132+054+139+728+254+725+345+065+210+740+134+334+125+455+184+853)/22 = $335,977
2. Median:
• Median for June 2006: Median of ordered data is the value in the middle of the data set, It is the 11th value in order set. we can see that it is $254,000
• Median for June 2005: Median of ordered data is the value in the middle of the data set, It is the 11th value in order set. we can see that it is $139,000
3. Mode:
• Mode for June 2006: There is no mode, because no value is repeated.
