The rate at which Riya is applying the mulch to the garden is 250000:1.

What is the rate?

It should be noted that rate is simply used to show the relationship between two things. A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio expresses the corresponding rate of change in the dependent variable if the denominator of the ratio is written as a single unit of one of these quantities and it is assumed that this quantity may be modified systematically (i.e., is an independent variable).

Per unit of time is a frequent sort of rate, and examples include speed, heart rate, and flux. Exchange rates, literacy rates, and electric field ratios are examples of ratios with a non-time denominator (in volts per meter).

From the information, Riya is applying mulch to the garden and she applied at a rate of 250000cm³ for every m² of space.

5. Find the lowest number which is exactly divisible by 14 and 16.

Answers

Answer:

112

Step-by-step explanation:

Find the lowest common multiple of 14 and 16.

To find the lowest common multiple:

1) Break the numbers down into their prime factors.

14 = [tex]2^{1}[/tex] x [tex]7^{1}[/tex]

16 = 2 x 8 = 2 x 2 x 4 = 2 x 2 x 2 x 2 = [tex]2^{4}[/tex]

2) Multiply the highest power of each prime number.

We have three numbers, but only two are unique: [tex]2^{1}[/tex] , [tex]7^{1}[/tex] and [tex]2^{4}[/tex]

[tex]2^{4}[/tex] > [tex]2^{1}[/tex] , so we will use [tex]2^{4}[/tex]

[tex]7^{1}[/tex] x [tex]2^{4}[/tex] = 7 x 16 = 112

Scores on an exam follow an approximately normal distribution with a mean of 76. 4 and a standard deviation of 6. 1 points. What is the minimum score you would need to be in the top 2%?.

Answers

If scores on an exam follow an approximately normal distribution with a mean of 76.4 and a standard deviation of 6.1 points, then the minimum score you would need to be in the top 2% is equal to 88.929.

This type of problem can be referred to as a normal distribution problem.

It can be solved by using the z-score.

Formula;

Z = x - μ / σ

Here,

Z represents the standard score

x represents the observed value

μ represents the mean

σ represents the standard deviation

The z- score can be found by using the p-value on a standard table.

As the minimum score to be in the top 2% is needed to be found, p-value = 0.02

z- score that corresponds to the p-value of 0.02 in the standard table is equal to 2.054

Hence,

2.054 = x - 76.4 / 6.1

2.054(6.1) = x - 76.4

12.529 = x - 76.4

x = 12.529 + 76.4

x = 88.929

Hence the minimum score needed to be in the top 2% is calculated to be 88.929

Answers

The inverse of the function x^7 is x^-7 and it is also a function.

An inverse function or an anti function is defined as a function, which can reverse into another function.

A standard method to find inverse of a function is to set y=f(x)

let y= f(x)=x^7

thus

[tex]\sqrt[7]{y}[/tex]=x

thus [tex]f^{-1}[/tex](y)=[tex]\sqrt[7]{y}[/tex]

thus [tex]f^{-1} (x)=\sqrt[7]{x}[/tex]

(To verify this if a function is inverse or not we are required to check for the identity)

(n = the number of boxes)

Taxi = 20n

The break-even point is when these are the same.

150 + 5n = 20n

150 = 15n

n = 150/15 = 10

So with 10 boxes, it costs the same ($200) either way.

With 11 boxes, the Moving Company costs $205

With 11 boxes, the Taxi would cost $220.

It is cheaper to use the moving company with 11 or more boxes.

Answers

Math reality is more restrictive and logical, physical reality is more "free" and well-behaved.

How is "Mathematical Reality" different than physical reality?

Mathematics are a logical construct, thus, everything in the "mathematical realty" must follow a certain logic.

For example, in math, always that you do a simplification (like rounding, applying a theorem, using an integration property, etc) you need to prove logically why you can do that.

While on physics we assume the reality is "nice" and we can always apply the simplifications. This is because most of the functions that represent physics are nice (continuous, differentiable, etc) functions, in the same way, most of the matrices are square matrices, and so on.

Concluding, for example in math the number 4.99999 is exactly 4.9999

On physics, if that same number represents a measure, for example:

4.99999 meters is practically equal to 5 meters.

Math reality is more restrictive and logical, physical reality is more "free" and well-behaved.

The equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6

From the question, we are to determine the equation of the line that is perpendicular to the given equation.

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line.

That is,

If m₁ is the slope of one of the lines

and m₂ is the slope of the other line

Then,

m₁ = -1/m₂

First, we will determine the slope of the given line

The equation of the given line is

y = 3x - 9

Compare the equation to the general form of the equation of a straight line

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison,

m = 3

∴ The slope of the given line is 3

Thus,

The slope of the line that is perpendicular to this line is -1/3

Now,

To determine the equation this line,

We have that the line passes through the point (3, 1)

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

m = -1/3

x₁ = 3

y₁ = 1

Putting the parameters into the equation,

y - 1 = -1/3(x - 3)

Expressing the equation in standard form

3(y -1) = -1(x - 3)

3y - 3 = -x + 3

3y + x = 3 + 3

x + 3y = 6

Hence, the equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6

While conducting financial analysis, it's possible that we'll need to date a report.

Additionally, the function's capabilities include the ability to merge several values into a single time value.

formula= TIME (hour, minute, second)

distance = rate X time

D = RT

T = D/R

20 feet per second = 1200 feet per minute

16 feet per second = 960 feet per minute

(D/R) + 19 + (D/R) = 21

(D/R) + 19 + (D/R) = 21

(D/1200) + 19 + (D/960) = 21,

Let x represent the number of acres that Annie can mow in hour.

Also convert 1 hour to minutes

1 hour = (1 × 60)min = 60min

Annie can mow 1/6 of an acre in 50 minutes

Annie can mow x of an acre in 60 minutes
