Answer:
y = -x + 3
Step-by-step explanation:
y = x - 3 This equation has a slope of 1
A line that would be perpendicular to the above line would then need a slope of -1
If the line has a slope of -1 and passes through (2, 1) then we can plug into
y = mx + b to get the 'b' value
1 = (-1)(2) + b
1 = -2 + b
3 = b
Equation would be y = -x + 3

The speed of sound is approximately 720 miles per hour at sea level. At this rate, how many feet does it travel in 20 seconds? Use 1 mile=5280 feet.
Answer: 21120 feet.
Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.
The distance travelled by sound in 20 seconds is 21120 feet.
What is speed?In unit time the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 720 miles per hour.
According to given condition,
1 hour = 720 miles
Since, 1 hour = 60 minutes
60 minutes = 720 miles
1 minute = 12 miles.
1 minute = 60 seconds
60 second = 12 miles
1 second = 12 / 60 = 1/5 miles
20 second = 20 / 5 = 4 miles
According to given condition,
1 mile = 5280 feet
Therefore,
20 second = 5280 x 4 = 21120 feet
The distance travelled in 20 seconds is 21120 feet.

Find the measure of angle x in the figure.
Answer:
8
Step-by-step explanation:
We know that angles in a triangle add up to 180, so:
5x-60+2x+40+3x-80=180
Simplify
10x-100=180
Solve
Subtract 100 from both sides
10x=80
Divide 80 by 10 to find x
x=8
five times a number increased by seven is equal to forty-seven what is the number
Answer: The number is 8
Please mark brainliest
Step-by-step explanation:
8 is the value of the unknown number 'x' from the equation 5x + 7 =47.
What is linear equation?
" Linear equation is defined as the algebraic expression which has highest power of the given variable equals to one."
According to the question,
'x' represents the unknown number.
As per the condition given linear equation we get,
5x + 7 = 47
Add (-7) both the sides
5x + 7 + (-7) = 47 + (-7)
⇒5x = 40
Divide by 5 both the sides we get,
(5x) / 5 = 40 / 5
⇒ x = 8
Hence, 8 is the value of the unknown number 'x' from the equation 5x + 7 =47.

x + 4 - 3 = 1
x + 1 = 1
x = 0
Answer:
x = 8
Step-by-step explanation:
√x + 4 - 3 = 1
1) Move constant terms to the opposite side of the equation: √x + 4 = 1 + 3
2) Simplify the right side: √x + 4 = 4
3) Now square both sides to eliminate the square root: (√x + 4)^2 = 4^2 (x + 4) = 16
4) Move the constant term to the other side: x + 4 = 16 – 4
5) Simplify the right side: x + 4 = 12
6) Move constant side to the other side: x = 12 – 4
7) Finally, after simplifying the right side again, you get: x = 8
Therefore, the solution to the equation √(x + 4) - 3 = 1 is x = 8.

A carpet measures 7 meters 3 decimeters in length and 4 meters 2 decimeters in width. What is its area in square meters?
Answer:
C
Step-by-step explanation:
change decimetres into metres
length - 7.3m
Width - 4.2m
to find an area, do length times width
7.3 x 4.2 = 30.66 square metres
I hope this helped :)
Answer:
C. 30.66 square meters
Step-by-step explanation:
The equation for area is A = L × W
L = length
W = width
Because a demimeter is 1 tenth of a meter your new measurements are 7.3 and 4.2.
multiply the measurements to find the area of 30.66² meters

What is the relationship between mass, density and volume? Provide and example that involves calculating population density.
Answer:
Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.
