Let the unknown variable be n.Given the following data:
Output = 8a. To represent the statement as an algebraic equation:
In this exercise, you're required to write a mathematical expression (algebraic equation) that represents the word sentence given.
Translating the word sentence into an algebraic expression, we have;
The product of 0.4 and a number is 8:
[tex]0.4n = 8[/tex]
b. To determine the solution set using the replacement set:
Let's use the following set of numbers (0, 1, 10, 20)When n = 0:
[tex]0.4(0)=8\\\\0\neq 8[/tex]
When n = 1:
[tex]0.4(1)=8\\\\0.4\neq 8[/tex]
When n = 10:
[tex]0.4(10)=8\\\\4\neq 8[/tex]
When n = 20:

The magnitude, M, of an earthquake is represented by the equation M=2/3log (E/E0) where E is the amount of energy released by the earthquake in joules and E0=10^4.4 is the assigned minimal measure released by an earthquake.
To the nearest tenth, what would be the magnitude of an earthquake releasing 2.1⋅ 10^14 joules of energy?
Answer:
4.5*10^12
Step-by-step explanation:
5.5=2/3log(E/10^4.4)
8.25=log(E10^4.4)
10^8.25=E/10^4.4
E=10^4.4*10^8.25
E=10^12*4.5

The sum of two numbers is 25 and their difference is 13. Find their product.
Step-by-step explanation:
x + y = 25
x - y = 13
x.y = ?
x + y = 25
y = 25 - x
x - y = 13
x - 25 + x = 13
2x = 13 + 25
2x = 38
x = 38/2
x = 19
y = 25 - x
y = 25 - 19
y = 6
(x, y) = (19,6)
So, find their product!!
= x.y
= 19 × 6
= 114

Point E is located at (8-,7) point F is located at (9,7). What is the distance in units between point E and point F?
Answer:
[tex]d=\sqrt{197}}[/tex]
Step-by-step explanation:
Use the distance formula to find the distance between two points.
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
Plug in your coordinate points into x and y.
[tex]d=\sqrt{(9-8)^{2}+(7-(-7))^{2}}[/tex]
Solve for d.
[tex]d=\sqrt{(1)^{2}+(14)^{2}}[/tex]
[tex]d=\sqrt{197}}[/tex]
The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK : KL : LM is equal to 2:1:2. If JM=30, find JL.
JKLM forms a line segment. In this, the ratio of JK : KL : LM is equal to 2:1:2. We know that JM = 30 cm.
JK = 2x
KL = x
LM = 2x
JM = JKLM = 30 cm
JL (JK + KL) = 2x + x = 3x
So,
JL + LM = JKLM
3x + 2x = 30
5x = 30
x = 30/5
x = 6.
JL = 3x = 3 × 6 = 18 cm.
=》 JL = 18 cm.

Plot two points to represent the temperatures -0.9°F and -1.2° on the number line
Red = -1.2°
Blue = -0.9 °
Answer Below:
The line represents the range of temperatures, and the points (-0.9°F and -1.2°F) are marked at their appropriate positions on the number line.
-1.2°F -0.9°F
|------------------|------------------|
A number line represents a range of numbers in order.
The numbers increase as we move to the right and decrease as we move to the left.
Now, we have to plot -0.9°F and -1.2°F on a number line:
-0.9°F:
Start at the origin (usually marked with 0), move slightly to the left, and place a point there.
This point represents -0.9°F.
-1.2°F:
Start at the same origin, move further to the left, and place another point there.
This point represents -1.2°F.
So, on the number line, we would have something like this:
-1.2°F -0.9°F
|------------------|------------------|
The line represents the range of temperatures, and the points (-0.9°F and -1.2°F) are marked at their appropriate positions on the number line.

Given the following
The rate at which the fan blows = 30rps
The time it takes to blow = 10s
Required
number of laps it has made to a stop
Using the formula
Rate = Number of laps/time
30 = Number of laps/10
Number of laps = 30 * 10
Number of laps = 300
Hence the number of laps it has made to a stop is 300 laps

Answer:
B. 4/5
Step-by-step explanation:
The function g(x) undergoes a reflection over the x-axis, a horizontal shift left 4 units, and a vertical shift down 2 units to become f(x).
Which equations describes f(x)?
a. f(x)=|−x+4|−2
b. f(x)=|−x−4|−2
c. f(x)=−|x+4|−2
d. f(x)=−|x−4|−2
please only answer if you know correct answer, I will give brainliest.
f(x) = -|x+4|-2
============================================================
Explanation:
The parent function is g(x) = |x| which is the absolute value function.
Reflect it over the y axis to get -|x|
Replace x with x+4 to shift the graph 4 units to the left. So we have -|x+4|
Lastly, tack on a -2 at the end to shift 2 units down
We'll end up with f(x) = -|x+4|-2 which is choice C.
The sequence of graphs, showing the step by step transformation process, is shown below.
The equation describes function f9x) will be f(x) = -|x+4|-2. The correct option is C.
What is an absolute function?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
Given that function g(x) undergoes a reflection over the x-axis, a horizontal shift left 4 units, and a vertical shift down 2 units to become f(x).
The parent function is g(x) = |x| which is the absolute value function. Reflect it over the y-axis to get -|x|. Replace x with x+4 to shift the graph 4 units to the left. So we have -|x+4|. Lastly, tack on a -2 at the end to shift 2 units down
The final equation can be written as:-
f(x) = -|x+4|-2
Therefore, the equation describes function f9x) will be f(x) = -|x+4|-2. The correct option is C.

Given: 2x+1/3=1
Prove: x = 1
Solve to correctly complete the proof.
2x+13=1 = Given
2x+1=3 =
2x = 2 =
x = 1 =
Answer:
2x+13=1, Given.
2x+1=3, multiplied both sides by 3.
2x=2, subtracted 1 from both sides.
x=1, divided both sides by 2.
NOTE: Your school may use special names for all of those proofs. If so, I don't know what they are. Sorry.
Step-by-step explanation:
For the first non-given statement, everything is over 3. A simple law of fractions is that the top number/s is being divided by the bottom, so all we need to do to reverse it is multiply it all by 3. This includes the other side.
For the second, it begins to get much easier as we've past the hardest step. Subtracting 1 from both sides gets us 2x = 2.
For the third, it is again easier. All that's left is to divide by 2 because that's what x is being multiplied by. After we do that, x turns out to be 1.
