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

Answer:

The only correct answer is the second one, that the three in the tenths place is 10 times the amount in the 100ths place.

Step-by-step explanation:

The others are all wrong because the further the place, the less the value, so they cannot be ANY times the amount of a place closer to the decimal.

Answer:

2. y = x + 16; 0.21y = 0.27x + 2.88

Step-by-step explanation:

You have two conditions:

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

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

NO, it's false....

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.

The student's question involves the use of scientific notation and unit conversion in Mathematics.

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.

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.

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.

In the equation m = k + 3, m represents a dependent variable. Hence the correct option is 2.

In an equation, a variable is a placeholder for an unknown value.

"Dependent" means that its value depends on the value of another variable.

In this case, the value of m depends entirely on the value of k.

If you know the value of k, you can solve the equation for m and find its specific value.

k is the independent variable in this equation because its value is not determined by any other variable in the equation.

Hence the correct option is 2.

Answer:

(x - 2)*(x - 1) is the answer

Step-by-step explanation:

We have to divide the polynomial f(x) = x^{3}-8x^{2}+17x-10 by (x-5).

Now, after dividing f(x) gets simplified into (x-5)*(x^{2}-3x+2).

So, we need to factorize the quadratic equation x^{2}-3x+2.

i.e. x^{2} - 3x + 2 = x^{2} - x - 2x + 2 = x(x-1) - 2(x-1) = (x - 2)*(x - 1)

Therefore, f(x) again gets simplified into (x-5)*(x - 2)*(x - 1)

Now eliminating the common factor (x-5).

We get, [tex]\frac{x^{3}-8x^{2}+17x-10}{x-5}[/tex] = (x - 2)*(x - 1)

Step-by-step explanation:

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.
