determine the given equation is a liner equation . write yes or no . if yes write the equation in a standard form
7n - 8m = 4-2m
use standard form
Answers
Answer:
7n - 8m = 4-2m is a linear equation. Rewritten:
6m + 7n = 4
Step by Step Explanation:
7n - 8m = 4-2m can be simplified by combining terms as if to solve. Add 2m to both sides of the equation..
7n - 8m +2m = 4-2m+2m leaves
7n + 6m = 4
It can be rewritten in slope-intercept form:
n = -6/7 m + 4

The height of a mountain is 24,000 feet. Of this height, 22,000 feet is above sea level and 2,000 feet is below sea level. Which set of integers represents the heights of the mountain above and below sea levels? pick the right expression that equal the word problem.
A. { 22,000, 2,000}
B. { 22,000, 2,000}
C. { 22,000, 2,000}
Answers
The answer is A {+22,000 -2,000}
This is because sea level is counted as 0 on a topographical map and any distance below sea level is counted in -ft. So if you the problem is amount above sea level to amount below sea level then you have 22,000 above sea level which would be +22,000 ft. And two thousand below. Then you just put that in the brackets “{}” and you are done.

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

A middle school club is planning a homecoming dance to raise money for the school. Decorations for the dance cost $100, and the club is charging $10 per student that attends.
Which graph describes the relationship between the amount of money raised and the number of students who attend the dance?
Answers
The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".
To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.
The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.
The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100

1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?
Answers
Answer:
\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
\(A = \frac{h_{b}+b}{2}\)
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
By using trigonometric relations we will see that the area is:
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Answer:
10. 91.08mm
11. 33.12in
12. 41.4yd
Step-by-step explanation:
To find the answer to each, we first need to calculate the circumference:
(use 3.14 for π)
(2 * Diameter) * π = Circumference
Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.
(Circumference / 2) + Diameter
Do this for each semi-circle as shown here:
10. (2 * 22) * 3.14 = 138.16
(138.16 / 2) + 22 = 91.08
11. (radius is given so double the middle)
(2 * (2 * 4)) * 3.14 = 50.24
(50.24 / 2) + 16 = 33.12
12. (2 * 10) * 3.14 = 62.8
(62.8 / 2) + 10 = 41.4

3. The ______ projection shows the size and shape of continents accurately but distorts water areas.
A. Conic
B. Mercator
C. Robinson
D. Interrupted
Answers
The correct answer is A. Conic projection.
A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.
Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.
Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.
Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.
Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian
