A tilt level and a dumpy level are both surveying instruments used for measuring horizontal distances and vertical elevations. The main difference is that the tilt level has a built-in compensator that eliminates the need for manual leveling, while the dumpy level requires manual leveling before each use.
Explanation:A tilt level and a dumpy level are both surveying instruments used for measuring horizontal distances and vertical elevations. However, there are some key differences between the two.
Tilt Level: A tilt level, also known as a tilting level, is a type of level that utilizes a compensator mechanism to maintain a level plane even when the instrument itself is not level. This compensator allows for accurate measurements and eliminates the need for manually leveling the instrument each time.
Dumpy Level: A dumpy level, on the other hand, is a more traditional type of level that requires manual leveling before each use. It consists of a telescope mounted on a tripod, and the instrument is adjusted using leveling screws to ensure that it is perfectly horizontal. The dumpy level does not have a compensator like the tilt level, so the instrument needs to be leveled manually to obtain accurate measurements.
In summary, the main difference between a tilt level and a dumpy level is that the tilt level has a built-in compensator that eliminates the need for manual leveling, while the dumpy level requires manual leveling before each use.

Given that f(x) = 6x 2 and g(x) =2x=4/5 , solve for g(f(1))
Answer:
The answer would be 4.
Step-by-step explanation:
What you have to do here is you have to substitute
So the problem told you the f(x) = 1. So what you want to do is plug that into the function f(x).
So:
f(x) = 6(1)2
= 8
Now we know that f(x) = 8, so what we going to do now is plug f(x) into g(x).
So:
g(f(8)) = 2(8) + 4/5
= 4
The value of g(f(1)) is 4.
Composite function -Composition of functions is the process of plugging one function into another, and simplifying or evaluating the result at a given x-value. Another way to read it is "f circle g of x." It is a process that joins two functions to create a third, unique function.Given ,
f(x) = 6x + 2
g (x) = 2x + 4 /5
To get value of g(f(1)) first we have to solve f(x).
f(x) = 6x + 2 .......................(1)
We simply put x = 1 in equation 1 .
Then, F(1) = 6 × 1 + 2 ⇒ 8
Now , we put value of f(1) in g(f(1)) ,
So, g(f(1)) = [tex]\frac{2x + 4}{5}[/tex]
= [tex]\frac{2 * 8 + 4}{5}[/tex]
= [tex]\frac{16 + 4}{5}[/tex]
= 20/5 ⇒ 4
Therefore, the value of g(f(1)) is 4 .

Egypt is 386,700 square miles and wyoming is about 97,818 square miles egypt is about how many times as large as wyoming
Egypt is approximately 4 times as large as Wyoming when comparing their areas.
Explanation:To calculate how many times larger Egypt is compared to Wyoming, we divide the area of Egypt by the area of Wyoming. The area of Egypt is 386,700 square miles, and the area of Wyoming is about 97,818 square miles.
Dividing the area of Egypt by the area of Wyoming gives us: 386,700 / 97,818 ≈ 3.95.
Therefore, Egypt is approximately 4 times as large as Wyoming.

Select all ratios equivalent to 20:4
4:20, 2:10, 15:3, 1:2
Final answer:
The only ratio equivalent to 20:4 from the given choices is 15:3 because, when simplified, both ratios reduce to 5:1.
Explanation:
To determine which ratios are equivalent to 20:4, we need to find ratios that can be simplified or scaled to form the same relationship. An equivalent ratio maintains the proportion when both terms are multiplied or divided by the same number.
First, the given ratio of 20:4 can be simplified by dividing both terms by 4, which gives us 5:1. Now, we can compare this to the choices provided:
4:20 is not equivalent because when simplified (divided by 4), it gives 1:5, which is the inverse of 5:1.2:10 simplifies to 1:5 (dividing by 2), also not equivalent for the same reason.15:3 simplifies to 5:1 (dividing both terms by 3), which is equivalent to 20:4.1:2 is already in simplest form and is not equivalent to 5:1 or 20:4.Therefore, the only ratio equivalent to 20:4 given in the choices is 15:3.

What is the difference between slope on a table and slope on a graph
The difference between slope on a table and slope on a graph is shown below:
The slope on a table refers to the rate of change between two points represented in a table of values.
It is calculated by finding the ratio of the change in y-values to the change in x-values between two points.
The slope on a table is determined by taking the difference in y-values and dividing it by the difference in x-values.
On the other hand, the slope on a graph refers to the steepness or incline of a line that connects two points on a graph.
It is calculated by the ratio of the vertical change (rise) to the horizontal change (run) between two points on the graph.
While both the slope on a table and the slope on a graph represent the rate of change, they are determined differently.

4y2 + 25y + 6
Answer:
factored form of given equation [tex]4y^2+25y+6[/tex] is [tex](4y+1)(y+6)[/tex]
Step-by-step explanation:
Given equation [tex]4y^2+25y+6[/tex]
We have to write the given equation in factors form and then represent the factors on grid.
Consider the given equation [tex]4y^2+25y+6[/tex]
25y can be written as 24y + y , we get
[tex]\Rightarrow 4y^2+24y+y+6[/tex]
Taking 4y common from first two term and 1 common from last two term, we get,
[tex]\Rightarrow 4y(y+6)+1(y+6)[/tex]
[tex]\Rightarrow (4y+1)(y+6)[/tex]
Thus, factored form of given equation [tex]4y^2+25y+6[/tex] is [tex](4y+1)(y+6)[/tex]

Step-by-step explanation:
Slope intercept form:
The equation of line is given by:
[tex]y=mx+c[/tex] .....[1]
where, m is the rate or slope and c is the y-intercept or initial value.
As per the statement:
Here, y represents the distance in kilometer and x represents the time in minutes.
A student is running a 10-kilometer race
⇒y(0) = b = 10 km
It is also given that he runs 1 kilometer every 4 minutes.
Now, with each passing minute the student is getting closer and closer to the finish line which was 10 kilometers away when the race started. Thus, as the race progresses, the distance between the student and the finish line will decrease.
[tex]m =-\frac{1}{4}[/tex]
Substitute these in [1] we have;
[tex]y = -\frac{1}{4}x+10[/tex]
Therefore, the function that describes his distance from the finish line is, [tex]y = -\frac{1}{4}x+10[/tex]
