Answer: To find Janice's running speed, we need to determine how many miles she runs per hour.

We know that the track is 1/4 mile long and Janice can complete each lap in 1/10 of an hour. To find the total number of miles Janice runs in an hour, we can multiply the length of the track by the number of laps she completes in an hour.

Length of the track * number of laps = total miles

1/4 mile * (1/10 hour)^-1 = total miles

On the second equation, we are using the inverse of the time, to get the number of laps completed in an hour

The speed is distance over time, so we need to express the distance in miles and the time in hours.

So Janice's running speed is 4 miles/hour.

Step-by-step explanation:

The slope-intercept form of the equation is y = - mx + b.

The equation of a line can be expressed in a variety of ways. Although they may differ in appearance, all of them describe the same line because multiple equations can describe the same line. However, all linear equations describing the same line are equivalent.

The formula y = mx + b can be used to represent any straight line. Any straight line equation, known as a linear equation, can be expressed as y = mx + b, where m denotes the line's slope and b its y-intercept. The value of y at the line's intersection with the y-axis is its y-intercept.

Given a graph of the equation, choose two points on the line and use them to calculate the slope in order to put the equation in slope-intercept form. This is the answer to the equation's question. Next, determine the y-coordinates, intercept's which should be of the type (0,b). The value in the equation is the y-coordinate.

Thus, the equation derived from the graph is as follows:

Since we are aware that the slope here is negative,

Therefore Our formula is y = -mx + b.

Answer:

Step-by-step explanation:

-1 = 7 - x

On this case, what you want to achieve is for all the constants to go to one side of the equation and all the variables would be on the other side of the equation. Let us transpose 7 to the left side of the equation.

subtract 7 on both sides

-1 = 7 - x

-1 - 7 = 7 - 7 - x

Simplify

-8 = -x

Divide both sides by -1

-8/-1 = -x/-1

8 = x

The answer to the question is x=8. It is an example of a linear equation.

A linear equation is an algebraic equation that represents a straight line when graphed on a coordinate plane. It consists of variables, constants, and coefficients, with the variables raised to the power of 1 (i.e., they are not squared or cubed).

A general form of a linear equation with one variable, let's say x, is:

ax + b = 0

Here, 'a' and 'b' are constants, and 'x' is the variable. The coefficient 'a' represents the slope or gradient of the line, while the constant term 'b' represents the y-intercept, which is the point where the line crosses the y-axis.

In this question,

-1 = 7-x (Given)

so, x = 7+1

        =8

Therefore, the solution to the equation is x=8.

(my trick to calculate percentage) to calculate 1% of 70 we do 70/100= 0.7, then we multiply 0.7 with the percent which is 80, so 0.7*80=56

therefor the answer is 56!

Answer:

D. 56

Step-by-step explanation:

80% can also be said as 80/100 and then multiply that with the total value of the thing you need to find.

So in this case its 70.

Now 70x(80/100) [remember the BODMAS rule] solve the bracket first.

80/100 = .8 x 70 = 56

hence the option D

To find the three numbers, we need to use the information given about their mean, median, and range. Since the median is 18, we know that the middle number of the three must be 18. Also, since the mean is 20, the sum of the three numbers must be 3 times 20, which is 60. So, the 3 numbers are 16, 18, and 26.

Let's call the smallest number x, then the largest number must be x+10 since the range is 10.
Now we can set up an equation to solve for x. We know that the sum of the three numbers is 60, so we can write:
x + 18 + (x+10) = 60
Simplifying this equation gives:
2x + 28 = 60
Subtracting 28 from both sides gives:
2x = 32
Dividing by 2 gives:
x = 16

Therefore, the three numbers are 16, 18, and 26.
Given the information provided, we know the following:
1. Mean of 3 numbers is 20.
2. Median of the 3 numbers is 18.
3. Range (largest - smallest) is 10.
Since there are 3 numbers and the median is 18, the middle number is 18. Let's call the smallest number "x" and the largest number "y". We can now write two equations:
1. (x + 18 + y) / 3 = 20
2. y - x = 10
We can simplify the first equation to find the sum of the 3 numbers:
x + 18 + y = 60
Now, we can solve for x in the second equation:
x = y - 10
Substituting the value of x in the first equation:
(y - 10) + 18 + y = 60
Solving for y:
2y = 52
y = 26
Now, we can find the value of x:
x = 26 - 10
x = 16
So, the 3 numbers are 16, 18, and 26.

The original dimensions of the piece of metal are 39 inch by 24 inches.

Let the breadth of the rectangular piece be b inches.

Hence, according to the data given in the question,

Length of the rectangular piece will be (b + 15) inches.

After 4 squares of 3 inches each are cut from the corners of the rectangular piece, the length and breadth of the piece becomes:-

Length = b + 15 - 3 - 3 = (b + 9) inches

Breadth = b -3 -3 = (b - 6) inches

The height of the subsequent open box made will be 3 inches.

We have,

Volume of the cuboidal open box = 1782 cubic inches.

Also, we know that,

Volume of cuboid = l*b*h

Where,

l is the length,

b is the breadth, and

h is the height

Hence,

(b+9)(b-6)(3) = 1782 cubic inches

(b+9)(b-6) = 1782/3 = 594

We can write 594 as 33*18

Hence,

(b+9)(b-6) = 33*18

b+9 = 33 or b-6 = 18

b = 33-9 = 18+6 = 24

Spherical harmonics are an integral part of quantum mechanics. They describe the shape of the orbitals, which electrons occupy in atoms. Moreover, the spherical harmonics provide the angular distribution of a wave in spherical coordinates. In 3D, the spherical harmonics can be written as:

Ylm(θ, φ) = √(2l + 1)/(4π) * √[(l - m)!/(l + m)!] * Plm(cosθ) * e^(imφ)

Here, l and m are known as the angular quantum numbers. They define the shape and orientation of the orbital. Plm(cosθ) represents the associated Legendre polynomial, and e^(imφ) is the exponential function. The spherical harmonics have various forms, including:

Y1,1 = -Y1,-1 = 1/2 √(3/2π) sinθe^(iφ)

Y1,0 = 1/2 √(3/π)cosθ

Y2,2 = 1/4 √(15/2π)sin²θe^(2iφ)

Y2,1 = -Y2,-1 = 1/2 √(15/2π)sinθcosφ

Y2,0 = 1/4 √(5/π)(3cos²θ-1)

Y0,0 = 1/√(4π)

In sharecropping contracts, the landlord receives a fixed share of the output, while in fixed rent contracts, the landlord receives a fixed amount. On the other hand, in sharecropping contracts, the tenant receives a fixed share of the output, whereas in fixed rent contracts, the tenant receives a fixed amount.

Sharecropping and fixed rent contracts are two different arrangements between landlords and tenants in agricultural settings. In a sharecropping contract, the landlord's compensation depends on the output of the land. Specifically, the landlord receives a fixed share or proportion of the output produced by the tenant. This means that if the tenant's effort leads to a high output, the landlord's share will be larger, and if the output is low or zero, the landlord's share will be correspondingly smaller. The tenant, in turn, receives a fixed share of the output as their compensation.

On the other hand, in a fixed rent contract, the landlord's compensation is predetermined and does not depend on the output. The landlord receives a fixed amount of rent regardless of the output produced by the tenant. This fixed amount ensures that the landlord's income remains stable and is not influenced by the variability of agricultural output. In this case, the tenant also receives a fixed amount as their compensation, which is unaffected by the output.

Answer:

Step-by-step explanation:

First, we'll write the cost equations for each house, using the number of months since the initial purchase as the independent variable X:

For the house on Main Street:

Cost = 900X + 10,000

For the house on Empire Road:

Cost = 1050X + 4000

Next, we'll find the rate of change for each house by finding the slope of the respective cost equation:

The slope of the cost equation for the house on Main Street is 900. This means that for every month that passes, the cost of the house will increase by $900.

The slope of the cost equation for the house on Empire Road is 1050. This means that for every month that passes, the cost of the house will increase by $1050.

Now that we have found the rate of change for each house, we can compare them to determine which house has the greater rate of change:

Since the slope of the cost equation for the house on Empire Road is greater than the slope of the cost equation for the house on Main Street (1050 > 900), the house on Empire Road has a greater rate of change.

Finally, we can compare the initial values of each house by comparing the y-intercepts of the respective cost equations:

The y-intercept of the cost equation for the house on Main Street is 10,000, which means that the initial cost of the house is $10,000.

The y-intercept of the cost equation for the house on Empire Road is 4000, which means that the initial cost of the house is $4,000.

Since the y-intercept of the cost equation for the house on Main Street is greater than the y-intercept of the cost equation for the house on Empire Road (10,000 > 4,000), the house on Main Street has a greater initial value.
