7/8 & -8/7 are these line slope perpendicular or parallel or neither
Answer:
Perpendicular!
Step-by-step explanation:
If they were parallel they would have the exact same slope. If they are perpendicular their slopes would be opposite reciprocals of each other... which they are. Another trick to tell if two slopes are perpendicular is to multiply them by each other and if the answer equals -1 they are perpendicular:
7/8 • -8/7 = -1/1 = -1

Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours. How long, to the nearest tenth of an hour, will it take them to paint the room together?
Answer:
It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour = [tex]\frac{1}{2}[/tex]
Work done by Jamie in 1 hour = [tex]\frac{1}{6}[/tex]
Work one together in 1 hour = [tex]\frac{1}{2}+\frac{1}{6}[/tex]
Now take common denominator to add both fractions
LCD = 6, Multiply the first fraction by 3
[tex]\frac{1*3}{2*3}+\frac{1}{6}[/tex]
[tex]\frac{3}{6}+\frac{1}{6}[/tex]
Now add the numerators
[tex]\frac{4}{6}[/tex]
[tex]\frac{2}{3}[/tex]
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together = [tex]\frac{3}{2}= 1.5[/tex]
It will take 1.5 hours to paint the room together
The nearest tenth of an hour, will it take them to paint the room together is 1.5 hours.
Given data:
Time taken by Martha to paint a room is, 2 hours.
Time taken by Jamie to pain the same room is, 6 hours.
Then work done by each of Martha and Jamie in 1 hour is given as,
[tex]W_{Martha}=\dfrac{1}{2}\\\\W_{Jamie}=\dfrac{1}{6}[/tex]
Total work done in 1 hour is given as,
[tex]W_{total}=W_{Martha} + W_{Jamie}\\\\W_{total}=\dfrac{1}{2} + \dfrac{1}{6}\\\\W_{total}=\dfrac{6+2}{12} \\\\W_{total}=\dfrac{8}{12}\\\\W_{total}=\dfrac{2}{3}[/tex]
To find total hours of painting together, we take reciprocal of 2/3.
Then, time taken to paint together is, 3/2 = 1.5 hours.
Thus, we can conclude in the nearest tenth of an hour, will it take them to paint the room together is 1.5 hours.

A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles
To find the average speed of the plane, divide the total distance traveled, which is 3,360 miles, by the total time of the journey, which is 6 hours, resulting in an average speed of 560 miles per hour.
Explanation:The student's question involves calculating average speed, which is a concept in Physics, specifically within the topic of kinematics. To find the average speed of the plane you would use the formula:
average speed = total distance / total time
In this case, the plane travels 3,360 miles in 6 hours, so the calculation would be:
average speed = 3,360 miles / 6 hours = 560 miles/hour
This calculation demonstrates how to determine the average speed of an object in motion when given the total distance traveled and the total time taken. This concept is analogous to determining the average speed in other examples, such as a car journey or a train trip.
Alicia runs for exercising falicia runs 8 Miles and 6 days how many days will it take for her to run 36 miles
Alicia runs 8 miles in 6 days. By setting up a proportion, it's calculated that it will take her 27 days to run 36 miles at the same rate.
Calculating Days Needed to Run a Total Distance:
Alicia runs 8 miles in 6 days. To find out how many days it will take her to run 36 miles, we can set up a proportion. Since the number of days is directly proportional to the miles run, we can use the equation:
8 miles / 6 days = 36 miles / x days
By cross-multiplying, we get:
8 miles * x days = 6 days * 36 miles
x = (6 days * 36 miles) / 8 miles
The miles cancel out, leaving us with:
x = 216 / 8
x = 27 days
Therefore, it will take Alicia 27 days to run a total of 36 miles if she continues running at the same rate.

Which is an equation of the line that is perpendicular to 3x+y=-5 and passes through the point (3, -7)?
Answer:
y+7=1/3(x-3) in point slope
y=1/3x-8 in slope intercept form
Step-by-step explanation:
First put 3x+y=5 in slope-intercept form (y=mx+b)
y=-3x+5
Give that the slope is -3 the perpendicular slope would be 1/3
now using the points (3.-7)
y+7=1/3(x-3) in point slope
y=1/3x-8 in slope intercept form
Put it in Slope - Intercept Form:
3x + y = -5
-3x -3x
y = -3x - 5
Now plug in the ordered pair that is given:
(3, -7)
y = -3x - 5
-7 = -3(3) - 5
-7 = -9 - 5
-7 = -14

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Express the equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
Enter your answer in the box.
Answer:
y = 7x + 1
Step-by-step explanation:
If the slope and coordinates have already been given, you can plug the values into the following equation of a line:
y - y1 = m(x - x1)
Where y1 is the y coordinate, so in this case 8,
x1 is the x coordinate which is 1
m is the slope, so 7:
y - 8 = 7(x - 1)
Expand the brackets:
y - 8 = 7x - 7
To isolate the y, we need to move the -8 over to the other side making it a positive 8:
y = 7x - 7 + 8
y = 7x + 1
So the equation of the line is y = 7x + 1

A specific distance is approximately 63,500,00 mi. A fly is about 0.18 in. long ???
A) what is the distance written in scientific notation
B) what is the length of a fly written in scientific notation
C) change the distance to inches it would be 5.04×10 to the power of nine if we lined up the flies how many would it take to reach the distance in standard form and scientific notation.
Answer:
Step-by-step explanation:
a) Given that a specific distance is approximately 6350000 miles.
To write this in scientific notation. We know that for writing in scientific notation we must writte the given number as a positive number less than 10 x product of powers of n.
Hence this number
6350000 = 6.35 x1000000 = [tex]6.35x10^6[/tex] miles
b) Length of a fly = 0.18 inches.
To write this in scientific notation. We know that for writing in scientific notation we must writte the given number as a positive number less than 10 x product of powers of n.
so 0.18 = 1.8([tex]1.8(10^{-1}[/tex]
c) Given that distance = 5.04x10^9 inches
To line up number of flies required
= [tex]\frac{5.04x10^9}{0.18} = \frac{504x10^9}{18}=28(10^9)\\Answer is\\28(10^9)[/tex]
In this mathematical problem, the distance of 63,500,000 miles is written in scientific notation as 6.35 x 10^7. The length of a fly, 0.18 inches, is expressed in scientific notation as 1.8 x 10^-1. To find the number of flies to cover the distance, the distance is first converted to inches (5.04 x 10^9), which when divided by the length of a fly results in 2.8 x 10^10, meaning approximately 28,000,000,000 flies would be needed.
Explanation:The student's question involves the use of scientific notation and unit conversion in Mathematics.
Firstly, the distance given as approximately 63,500,000 miles can be written in scientific notation as 6.35 x 10^7 miles. The number is changed to a number between 1 and 10 by moving the decimal point 7 places to the left, hence the exponent 7. Secondly, the length of the fly given as 0.18 inches can be written in scientific notation as 1.8 x 10^-1 inches. The decimal point is moved 1 place to the right resulting in an exponent of -1. Lastly, to find out how many flies it would take to reach the distance, we first need to convert the distance from miles to inches. It is given that the conversion is approximately 5.04 x 10^9 inches. So, if we divide this by the length of a fly, i.e., 1.8 x 10^-1 inches, we would arrive at approximately 2.8 x 10^10 flies in both standard form and scientific notation. That is, it would take about 28,000,000,000 flies to reach the mentioned distance. Learn more about Scientific Notation and Unit Conversion here:

Marie mixes 16 liters of 18% acid solution with a 27% acid solution, which results in 21% acid solution. Let x represent the number of liters of 27% solution used and let y represent the number of liters of mixture. Which system of equations can be used to find the number of liters of 27% acid solution in the mixture?
1. y = x + 16; 0.27y = 0.21x + 2.88
2. y = x + 16; 0.21y = 0.27x + 2.88
3.y = x + 16; 0.21y = 0.27x + 4.32
4. y = x + 16; 0.27y + 2.88x = 0.21
Answer:
2. y = x + 16; 0.21y = 0.27x + 2.88
Step-by-step explanation:
You have two conditions:
Volume of 18 % + volume of 27 % = volume of 21 % Mass of acid in 18 % + mass of acid in 27% = mass of acid in 21 %For the first condition,
16 + x = y Transpose
(1) y = x + 16
=====
For the second condition
V₁c₁ + V₂c₂ = V₃c₃
16×0.18 + 0.27x = 0.21y
2.88 + 0.27x = 0.21y Transpose
(2) 0.21y = 0.27x + 2.88
The system of equations is y = x + 16; 0.21y = 0.27x + 2.88
