What is Rectangle?
The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.
The whole distance that a rectangle's boundaries, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides. Since a rectangle's perimeter is a linear measurement, the unit will be in meters, centimeters, inches, feet, etc.
Perimeter of a rectangle = 2(Length + Width) square units
Area of a rectangle = Length × Width = a × b

Write the ratio 1.8 : 4.2 inches Simplest for
The most simplified form of the given ratio 1.8: 4.2, which is a ratio of lengths in inches is 3/7.
What is meant by ratios?
In mathematics, a ratio shows how frequently one number appears in another. When expressed as a:b, a fraction has the form of a ratio. A ratio is a comparison or compressed version of two identical values. Like fractions, ratios can be entirely simplified. Divide all of the numbers in a ratio by the same number to make it simpler. Divide each integer in a ratio by their largest common factor to fully simplify the ratio. The ratio's numbers must always be whole numbers.
Given the ratio, 1.8: 4.2
The ratio can be simplified by dividing both the terms in the ratio by the highest common factor.
The highest common factor of 1.8 and 4.2 is 0.6.
So we divide both terms by 0.6.
1.8: 4.2 = 1.8/0.6 : 4.2/0.6 = 3:7
Therefore the simplified form of the given ratio, 1.8: 4.2 is 3:7.

Zack is expected to be at (-12,-10.5) by finding the midpoint of line segment WT and reflecting T over it.
What is coordinate ?
A coordinate is a set of numerical values that are used to identify the position of a point in a specific space, such as a two-dimensional plane or a three-dimensional space. In two-dimensional space, coordinates are commonly represented by an ordered pair (x, y) or (x, y, z) in three-dimensional space.
The problem states that the balloon lands at point W(42,-15) and Tahir ends up at point T(-18,36). We know that Tahir and Zack are flying off in opposite directions from point W at equal distances. To find the point where Zack is expected to land, we can use the midpoint formula which states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates.
We can find the midpoint of line segment WT by taking the average of the x-coordinates and y-coordinates:
x_midpoint = (x1 + x2) / 2 = (42 + -18) / 2 = 12
y_midpoint = (y1 + y2) / 2 = (-15 + 36) / 2 = 10.5
So the midpoint of line segment WT is (12,10.5). Since Zack is flying off in the opposite direction from Tahir at the same distance, we can expect Zack to end up at the point which is the reflection of point T over the midpoint of line segment WT.
This point would be (-12,-10.5)
Therefore , Zack is expected to be at (-12,-10.5) by finding the midpoint of line segment WT and reflecting T over it.

There are 128 three digit numbers divisible by 7
We know that the divisibility rule of 7 is:
If the difference between twice the unit digit of the given number and the remaining part of the given number is multiple of 7 or the difference is 0, then the number is divisible by 7.
the range of three digit numbers is 100 to 999
The first three-digit number divisible by 7 is 105 and the last three-digit number divisible by 7 is 994.
The numbers divisible by 7 must be: 105, 112, . . ., 994
We can observe that the above series represents the arithmetic progression with common difference d = 7, the first term a = 105 and the last term a_n = 994
We know that the formula for the n-th term of AP is:
a_n = a1 + (n - 1)d
994 = 105 + (n - 1)7
7n - 7 = 889

The length of a line segment can be measured either in metric units such as millimeters, centimeters, or customary units such as feet or inches.Rays - In geometry, a ray is usually taken as a half-infinite line (also referred to as a 'half line') with one or the two points and taken to be at infinity._____________________________________________________
So, in summary to all of this, it really depends on what concepts in geometry you are currently learning and which concept(s) you personally find the most useful and helpful.
What is the difference between a frequency histogram and a relative frequency histogram?
The vertical axis of a relative frequency histogram employs relative or proportional frequency rather than plain frequency, which is the only difference between it and a frequency histogram.
Explain the difference between frequency and relative frequency?Frequency can be expressed most simply in absolute terms. The number of times a specific value for a variable (data item) has been seen to occur in relation to the overall number of values for that variable is referred to as the relative frequency.Histogram is a term from the quality glossary. The frequency distribution of a collection of data reveals how frequently each unique value appears. The most typical graph for displaying frequency distributions is a histogram. Although it closely resembles a bar chart, there are significant variances.Relative frequencies, on the other hand, do not employ raw counts. Instead, they use percentages, proportions, or fractions to compare the count for one type of event to the entire number of events. The word "relative" refers to a specific tally in relation to the overall number, which is where it is used.Learn more about frequency histogram refer to :

What is the range of f/x )= Logbx?.
The range of the function f(x) = logbx is {y | y > 0}.
The range of the function f(x) = logbx is the set of all possible output values (or "y-values") that the function can produce. In this case, the function is a logarithm in base b, where b is a positive real number, and x is the argument of the logarithm, also a positive real number.
For a logarithm function, the range is all real numbers y such that y > 0, because the logarithm of a positive number is always positive. The domain of the function is all positive real numbers x because the logarithm of a positive number is always defined.
So, the range of the function f(x) = logbx is {y | y > 0}.
It's worth noting that the logarithm function is defined only for positive real numbers x, hence the domain of this function is x > 0 and the range is y > 0.
Also, the base of the logarithm b is a positive real number, different than 1, this ensures that the logarithm function is defined for all x > 0, for b = 1 it would not be defined for x = 1.

Doug etimate that hi occer team will win 7 game thi year. The team actually win 10 game. What i the percent error of Doug' etimate? Round the anwer to the nearet tenth percent if neceary
Doug's estimate was incorrect by 30% because probability his team won 10 games instead of the 7 he predicted.
Doug estimated 7 wins
Actual number of wins was 10
Error = (Actual - Estimate) / Estimate x 100
Error = (10 - 7) / 7 x 100
Error = 3 / 7 x 100
Error = 30%
Doug estimated that his soccer team would win 7 games this year. However, the team ended up winning 10 games in total. This means that Doug's estimate was incorrect by 30%. To calculate this percent error, we used the following formula: Error = (Actual - Estimate) / Estimate x 100. In this case, the actual number of wins was 10 and the estimate was 7. Plugging these numbers into the formula, we got that the error was 3/7 x 100, which is equal to 30%. This means that Doug's estimate was off by 30%. This is a significant overestimate since the team ended up winning 3 more games than what Doug had predicted.
