The focus of 76-inch diameter and the 42-inch deep reflecting telescope is located approximately 87.92 inches or 7.32 feet from the center of the mirror, at the prime focus.
The focus of a reflecting telescope's mirror is the point where incoming light rays converge after being reflected by the mirror. The location of the focus depends on the size and curvature of the mirror. In this case, the mirror has a diameter of 76 inches and a depth of 42 inches.
This information can be used to calculate the location of the focus, which is approximately 87.92 inches or 7.32 feet from the center of the mirror. This distance is also known as the prime focus and is the point where the image is formed. The eyepiece of the telescope, which magnifies the image formed at the prime focus, is typically located a short distance away from the prime focus, often around 0.90 inches.
The secondary mirror is positioned to reflect light from the prime focus to the eyepiece.

Recall that two angles are complementary if the sum of their measures is 90°
Find the measures of two complementary angles if one angle is 5° more than four times the other angle.
Answer:
I = 17deg, II = 73deg
Step-by-step explanation:
Let's say first angle is x, and then respectively, the second angle is 4*x + 5.
Their sum is 90 degrees, so:
x + (4*x+5) = 90
5x + 5 = 90
5x = 85 | :5
x = 17 degrees ==> first angle
4*x+5 = 73 degrees ==> second angle
In the continental United States the ratio of states the border an ocean to states that do not boarder an ocean is 7:9. How many states are landlocked and do not boarder an ocean.
There are 21 states landlocked and 27 states do not border an ocean.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Since there are 48 states in the continental United States, some of which are on the border of an ocean and some of which are not.
According to the question,
The ratio of the states having the border to the ocean and not having the border to the ocean = 7 : 9
Let the states having the border to the ocean = 7x
The states do not have a border to the ocean = 9x
Thus, 7x + 9x = 48
⇒ 16x = 48
⇒ x = 3
So, the states do not have a border to the ocean = 7 × 3 = 21
And, the states do not have a border to the ocean = 9 × 3 = 27

What is the difference between mixture and compound Class 9?.
The main difference between a mixture and a compound is that a mixture is a physical combination of substances while a compound is a chemical combination of elements.
In chemistry, a mixture is a combination of two or more substances that are not chemically combined and can be easily separated by physical means. The properties of a mixture depend on the properties of the individual substances that make it up, and the substances retain their original properties. Examples of mixtures include air, salt water, and a bowl of fruit.
A compound, on the other hand, is a substance that is made up of two or more elements chemically combined in a fixed ratio. The properties of a compound are different from those of the individual elements that make it up. The atoms in a compound are chemically bonded together and cannot be easily separated by physical means. Examples of compounds include water (H₂O), table salt (NaCl) and sugar (C₁₁H₂₂O₁₁).

After Carl ha ued 1 yard of cable how much cable will he have left explain how you found your anwer
Carl has 2 5/36 yard cable, more than 1 yard, not specified left.
What is yard ?
A yard is a unit of length measurement in the U.S. customary system and the imperial system. It is equal to 3 feet or 36 inches. The symbol for yard is "yd". It is mostly used in the United States and the United Kingdom for measuring small lengths, such as in construction, textiles, and landscaping.
Carl has three lengths of cable, 5/6 yard long, 1/4 yard long and 2/3 yard long. The total length of the cable that Carl has is:
5/6 + 1/4 + 2/3 = (30 + 15 + 40) / 36 = 85 / 36 = 2 5/36 yard
To check whether he has at least one yard of cable or not, we need to compare the total length of the cable he has (2 5/36 yard) with 1 yard. Since 2 5/36 is greater than 1, it means he has more than 1 yard of cable. So, he will have at least 1 yard of cable left after using some of it.

What is the linear inequalities?
Linear inequalities are mathematical expressions that describe a relationship between two variables that is linear in nature. The most common form of a linear inequality is of the form ax + by < c, where a, b, and c are constants and x and y are variables.
Yes, this system of two linear inequalities can be represented graphically on the x-y plane by plotting the solutions to each inequality. The steps are as follows:
Replace the equation with the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. For example, the first equation can be rearranged as:4x + 6y <= 24
=> -6y <= -4x + 24
=> y >= (4/6)x + 4
=> y = (4/6)x + 4
Plot the line corresponding to each equation. You can use the slope-intercept form of each equation to get the slope and y-intercept of each line, and then plot the line using the slope and y-intercept. For example, the line for the first equation is y = (4/6)x + 4, which is the graph of a line with slope 4/6 and y-intercept 4. The line for the second equation is y = (1/5)x + 2, which is the graph of a line with slope 1/5 and y-intercept 2.Determine the side of the line to shade in for each inequality. If the inequality is less than or equal to, shade in the region below the line. If the inequality is greater than or equal to, shade in the region above the line.The solution to the system of inequalities is the intersection of the shaded regions, which is the region where both inequalities are simultaneously satisfied.

21. The marks obtained by the students of class VII in the class test of Mathematics are given in the table below. Find the average marks. Marks obtained No. of students 10 3 20 6 30 10 40 7 50 4
Answer:
The average marks = 31
Step-by-step explanation:
We know that the average can be measured using mean
Mean = Sum of observations / no of observations
In the given data no of observations = sum of frequencies
= 3+6+10+7+4
=30
Sum of observations = No of marks * frequency 1 + No of marks * frequency 2+...
= 10*3 +20*6+30*10+40*7+50*4
= 930
Mean = 930/30
= 31
