Step-by-step explanation:

A. by making the ramp as long as possible

The students can reduce the effort needed to push the boxes up the ramp by making the ramp as long as possible.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

The students can reduce the effort needed to push the boxes up the ramp by making the ramp as long as possible.

A longer ramp will have a more gradual slope, which requires less force to push the boxes up.

This is because the longer the ramp, the smaller the angle of inclination, and the easier it is to move objects up the ramp.

While making the ramp out of lightweight material and covering the ramp’s surface with a soft rubber mat may make moving the boxes up the ramp easier, these factors are not as significant as the ramp's length.

Additionally, making the ramp’s height and length equal could make it too steep, requiring more effort to push the boxes up.

Therefore, by making the ramp’s height and length equal, students can reduce the effort.

Step-by-step explanation:

Think of a car. when you are going 15 miles an hour that means that every hour, you are crossing 15 miles. In this situation the dolphin is going 25 km for every hour. one hour would be 25, two hours would be 50 and so on.

A.  (N • p)(x) = -8x² + 320x

B.  (N • p - C)(x) = -8x² + 120x .

Function - a function is a relationship or expression involving one or more variables.  It has a set of input and outputs.  Each input has only one output.  The function is the description of how the inputs relate to the output.

given that -

N(x) = x

p(x) = 320 – 8x  for  0 ≤ x ≤ 10

C(x) = 200x

(N ∙ p)(x) =?

(N ∙ p – C)(x) =?

For the question A....

         (N ∙ p)(x) = N(p(x))

         N(p(x)) = N(320 – 8x)  

         N(p(x)) = x(320 – 8x)

       (N ∙ p)(x) =  320x - 8x²

For the question B....

      (N ∙ p – C)(x) = N.((p-c)(x))

      N.((p-c)(x)) = N.(p(x) - c(x))

      N.((p-c)(x)) = x.(320 – 8x) -(200x)

      N.((p-c)(x)) = 320x - 8x² - 200x

      N.((p-c)(x)) = -8x² - 120x

Thus , the function represent (N • p)(x) = -8x² + 320x and (N • p - C)(x) = -8x² + 120x . These are the relationship between N , P , C.

Answer:

The student played basketball for 40 minutes.

Step-by-step explanation:

Given that one week a student exercised for 2 hours at school and for 2/3 of an hour at home, it can be stated that the student exercised for 2 hours and 40 minutes (since 60 x 2/3 is equal to 40 ). Thus, in total the boy exercised for 160 minutes (2 x 60 + 40).

Now, since he spent 1/4 of that time playing basketball, the time spent doing this sport is determined through the following calculation:

160/4 = X

40 = X

Thus, the student played basketball for 40 minutes.

Step-by-step explanation:

the volume of a cone: 1/3 [tex]\pi[/tex]r^2 h

the volume of a right circular cone will be

1/3 [tex]\pi[/tex](5.1)^2 * 11.4

310.60 for a full circular cone.

for a right circular cone, we use 90/180 of the volume.

= 155.3

The volume of the cone is 121.8 in³.

A cone is a 3-dimensional shape that consists of a flat circular base and a tip known as the vertex.

Volume of a cone = [tex]\frac{1}{3}[/tex]πr²h

Where:

π = pi = 22/7

r = radius

h = height

Volume =  [tex]\frac{1}{3}[/tex] x 22/7 x 5.1² x 11.4 = 121.8 in³

Step-by-step explanation:

The continuous division method is an effective method to determine the GCF of two or more numbers, aside from the listing method where we are listing down the common factors before determining the greatest among them.

In continuous division, we are just simply dividing the numbers by their common factors until such time that we find no more common factors except for 1 to them to be divided. After which, we will just multiply the common factors that we used to divide them. The result will be our GCF. Let us try the exercise given above:

1. Find the GCF of 24 and 72

               2   /    24      72

               2   /     12      36

               2    /      6       18

               3    /      3        9

                   /       1        3

Since we keep on dividing the numbers by 2 for 3 repetitions, we arrived at 3 and 9 by which  we divide by 3 and we get 1 and 3 which we can no longer divide. So the GCF is: 2x2x2x3 = 24

Therefore, the GCF of 24 and 72 is 24.

2. Find the GCF of 24, 32 and 48

                   2  /   24   32    48

                  2   /    12    16   24

                   2  /     6     8     12

                        /     3     4      6

So the GCF is: 2x2x2 = 8

Therefore, the GCF of 24, 32 and 48 is 8.

3. Find the GCF of 18, 27 and 45.

                3  /  18     27     45

                3  /    6      9      15

                    /    2      3       5

So the GCF is: 3x3 = 9

Therefore, the GCF of 18, 27 and 45 is 9.

4. Find the GCF of 24 and 36.

            2   /  24      36

            2   /  12       18

            3   /   6         9

                 /   2         3

So the GCF is 2x2x3 = 12

Therefore, the GCF of 24 and 36 is 12.

The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. Before moving to solve the linear equations using the substitution method, get an idea on what the algebraic method and graphical method is.

Algebraic Method

An Algebraic method is a collection of several methods, which are used to solve a pair of the linear equations that includes two variables. Generally, the algebraic method can be sub-divided into three categories:

Substitution method

Elimination method

Cross-multiplication method

Graphical Method

The graphical method is also known as the geometric method and is used to solve the system of linear equations. In this method, the equations are designed based on the objective function and constraints. To solve the system of linear equations, this method has undergone different steps to obtain the solutions.

In this article, we will focus mainly on solving the linear equations using the first algebraic method called “Substitution Method” in detail.

Substitution Method Steps

For instance, the system of two equations with two unknown values, the solution can be obtained by using the below steps. Here, the list of steps is provided to solve the linear equation. They are

Simplify the given equation by expanding the parenthesis

Solve one of the equations for either x or y

Substitute the step 2 solution in the other equation

Now solve the new equation obtained using elementary arithmetic operations

Finally, solve the equation to find the value of the second variable

Graphing of Linear Equations

Solving Linear Equations

Linear Equations in Two Variables

Difference Between Linear and Non-Linear Equations

Elimination by Substitution Method

In this method, the elimination of the variable can be performed by substituting the value of another variable in an equation. Hence, this method is called the elimination by substitution method.

Let us assume the system of linear equations

2x+3y = 13 and x-2y = -4

Given:

2x+3y = 13  …  (1)

x-2y = -4 …(2)

The equation (2) can be written as

x = 2y-4 … (3)

Now, in equation (1) eliminate the variable x by substituting the equation (3).

Hence, equation (1) becomes

2(2y-4) +3y = 13

Now, apply the distributive property for the above equation,

4y-8+3y = 13

Now, solve the above equation for the variable y

7y – 8 = 13

7y = 13+8

7y = 21

y= 21/7

y= 3

Hence, the value of y is 3.

Now, substituting y=3 in the equation (2), we get

x- 2(3) = -4

x – 6=-4

x = -4+6

x = 2

Therefore, the value of x is 2.

Hence, the solution for the system of linear equations is:

x = 2 and y=3

To check whether the obtained solution is correct or not, substitute the values of x and y in any of the given equations.

Verification:

Use Equation (2) to verify the solution

x-2y = -4

Now, substitute x= 2 and y=3

2-2(3) = -4

2-6= -4

-4=-4

Here, L.H.S = R.H.S

Hence, the obtained solution is correct
