Answer:

Pia

Step-by-step explanation:

The smaller the number of pencils in a bundle the greater the number of  bundles.

For example if the number of pencils each has is 60,

Then the number of bundles for Pia = 60/10 = 6,

and    ...................................................Gauri  = 60/12 = 5,

and   .....................................................Yasmin = 60/20 = 3.

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:

Step-by-step explanation:

multiply 11 by seven and then add nine because thats what you had originally.

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....

Step-by-step explanation:

Let the slope of one line be 's' , then according to the given condition that the  slope of second line is negative reciprocal of the first , We obtain the slope of the second line as [tex]\frac{-1}{s}[/tex].

So, the product of both the slopes is given by [tex]s\cdot \frac{-1}{s}=-1[/tex]

This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1

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:

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

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.

Answer:

C (1.38)

Step-by-step explanation:

The graphed function has the slope 4/3, which is obvious:  As x increases from 0 to 1.5, y increases from -2 to 0.  Thus, m = rise / run = 2/1.5 = 4/3.

Which of the given functions have greater rates of change than 4/3?  These include A (1.86), B (1.4), C (1.38), E (1.67).  Of these, C has the lowest rate of change (1.38).

The lowest rate of change of the function is y = 11/8x + 3/8. The correct option is C.

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.

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.

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.

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.
