Solve 3x+ -1/3y = 20 for x:

3x=1/3y+20

What is the percent of change from 8,000 to 2,000?
Answer:
75% markdown
Step-by-step explanation:
If I am not mistaken, you can input this into everyday values like a shirt.
For example: If a shirt costs $8 but is on special for $2 then it is 75% off. Since 2 goes into 8 four times, 2 can be considered 25%. So since percent almost always add up back to 100, you take 100- 25 and you get a 75% markdown.

What is base and power?Raising a base number to an exponent is referred to as "power" in mathematics. It indicates that "base number" and "exponent" are the two fundamental components of powers. The exponent shows how many times the base number has been multiplied, whereas the base number is defined as a number that is multiplied by itself.
In a nutshell, power is a number that has exponents used to express it. It means that the same element has been multiplied repeatedly. In the context of powers, the following specific terminology may be used:
Whenever a number:
Squared = power is 2
cubed = Power is 3
to the power of n = used for powers more than 3
The data given gives as an equation as followed
⇒ [tex]4^{2x}[/tex] ÷ [tex]8^x[/tex] = 32
⇒ [tex](2^2)^{2x}[/tex] ÷ [tex](2^3)^{x}[/tex] = 32
⇒ [tex]2^{4x}[/tex] ÷ [tex]2^{3x}[/tex] = 32
⇒ [tex]2^{(4x - 3x )}[/tex] = 32 (If the base is same in a division, then the powers
⇒ [tex]2^x[/tex] = 32 can simply be subtracted with the base as common)
⇒ 2 = [tex]\sqrt[x]{32}[/tex]
⇒ 2 = [tex]\sqrt[5]{32}[/tex]
Thus, x = 5

Write a function that could be used to calculate the altitude of a plane arriving at JFK
International airport which was cruising at an altitude of 30,000 before it began its descent at a rate of 3,200 feet per minute. How many minutes would it be before the plane landed. Round your answer to the nearest tenth.
Answer:
The plane landed after 9.4 minutes.
Step-by-step explanation:
Function Modeling
The initial altitude of a plane arriving at JFK International Airport is 30,000 ft.
It then began its descent at a rate of 3,200 feet per minute.
Let's call t the number of minutes since the descent started. If each minute the plane descends 3,200 feet, then after t minutes it descends 3,200t.
This must be subtracted from the initial altitude, thus the altitude H is written as:
H = 30,000 - 3,200t
When the plane landed, its altitude was H=0, thus:
0 = 30,000 - 3,200t
Adding 3,200t:
3,200t = 30,000
Dividing by 3,200:
t = 30,000/3,200
t = 9.375 minutes
Rounding to the nearest tenth:
The plane landed after 9.4 minutes.
Explain how to use the circle to figure out the measurement if the angles.
Answer:
You can find the area of a sector of a circle if you know the angle between the two radii. A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around.
Step-by-step explanation:
That's the answer
The measure of each angle in the given circle is 120°.
What is the circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
Th given circle is divided into 3 equal parts.
We know that, central angle of circle measures 360°.
Now, each angle measures =360/3
= 120°
Therefore, the measure of each angle in the given circle is 120°.

Answer:
9, 24, 6, 16
Step-by-step explanation:
6/2 = x/3
x = 3*3 = 9
42/7 = x/4
x = 6*4 = 24
48/12 = 2x/3
2x = 4*3 = 12
x = 6
20/15 = x/12
x = 4/3*12 = 16
12, 18, x, and 5 are used to calculate an average of 13. What is the missing number?
Answer:
17
Step-by-step explanation:
Given the data:
12, 18, x, 5
Average of the numbers = 13
The value of x will. Be
Sum of 12, 18, x and 5 divided by the number of data values.
Mean(average) = Σ(X) / n
n = number of values
13 = (12 + 18 + x + 5) / 4
13 = (35 + x) / 4
13 * 4 = 35 + x
52 = 35 + x
x = 52 - 35
x = 17
