Answer: $251,535 is the total cost for all the laptops.

Step-by-step explanation:

615×409= 251,535

Answer:

[tex]total\ cost=\$251,535[/tex]

Step-by-step explanation:

For this exercise it is important to analize the information provided in the exercise.

According to the exercise, the of cost each computer is:

[tex]cost=\$409[/tex]

You know that the school district purchased 615 new laptops for their mobile labs; therefore, in order to calculate the total cost for all the laptops purchased, you must multiply the cost of one laptop ($409) by 615.

Therefore, you get that the total cost is the following:

[tex]total\ cost=(\$409)(615)\\\\total\ cost=\$251,535[/tex]

Answer:

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.

Step-by-step explanation:

Let p represents the number of transactions.

Each transaction is worth 10 points, then p transactions are worth 10p points.

Customers automatically earn 22 points when they sign up.

The total amount of points is

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.

Answer:

$60 - $104

Step-by-step explanation:

Based on what we know, we double $30 and double $52 which gives us $60 and $104. As we don't know the exact number we need to double we do that. This tells us that Daniela saved between $60 - $104.

If Julian saved between $ 30 and $ 52 over the summer. The inequality represents the amount of money Daniela saved which will be $ 60 < n < $ 104.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.

It is given that,n represents the amount of money and Julian saved between $ 30 and $ 52 over the summer.

The inequality represents the amount saved by Julian is,

$ 30<n<$ 52

If Daniela saved twice as much then he saved the amount between $ 60 and $ 104.If n shows the inequality for the amount Daniela saved then the inequality is shown as,

$ 60<x<$ 104

Thus, if Julian saved between $ 30 and $ 52 over the summer. The inequality represents the amount of money Daniela saved which will be $ 60 < n < $ 104.

Answer:

12.50x+30

Step-by-step explanation:

Answer:

[tex]y = 12.5x + 30[/tex]

Step-by-step explanation:

We are given the following information in the question:

Cost of a holiday meal = $12.50

Delivery fee = $30

Cost(y) represents the amount a holiday meal including delivery for x people.

[tex]cost = (\text{Cost of meal}\times x) + \text{Delivery chareges}[/tex]

Putting all the values,

[tex]y = 12.50\times x + 30\\y = 12.5x + 30[/tex]

The above equation gives the total amount of holiday meal for x people including the delivery charges.

The evaluation of the given mathematical expression 7•(x-8)-3 for x = 5 results in -24.

To evaluate the variable expression 7•(x-8)-3 for x = 5, we substitute the value of x into the expression.

This becomes 7•(5-8)-3, which simplifies to 7•(-3)-3, or -21-3. Therefore, the evaluation of the given expression for x = 5 is -24.

The length of Rectangle is 81 feet's.

We have a rectangle which has a length of 27 feet less than nine times its width and the area of the rectangle is 972.

We have the length of the rectangle.

The Area of a Rectangle = A = L x B

The Perimeter of a Rectangle = P = 2(L + B)

According to the question, we have -

Area = 972 square feet's.

Let the length of rectangle be x and width be y.

Then -

x = 9y - 27

Now -

Area = 972

xy = 972

y(9y - 27) = 972

9y(y - 3) = 972

y(y - 3) = 108

[tex]$y^{2} -3y -108 = 0[/tex]

(y - 12)(y + 9) = 0

y - 12 = 0       or        y + 9 = 0

y = 12             or         y = - 9

But width cannot be negative. Therefore -

y = 12.

Now, length = x = 9y - 27 = 12 x 9 - 27 = 108 - 27 = 81.

Hence, the length is 81 feet's.

Answer:

The range of the numbers make this true is (12 , 17)

Step-by-step explanation:

Lets explain how to solve the problem

The statement is:

→ Nine less than a number is between 3 and 8

Assume that the number is x

∵ The number is x

∴ Nine less than a umber is x - 9

→ The difference is between 3 and 8

∴ 3 < x - 9 < 8

∴ Nine less than a number is between 3 and 8 ≡≡≡ 3 < x - 9 < 8

Lets solve the inequality to find the range of x

∵ 3 < x - 9 < 8

Add 9 to each side

∴ 3 + 9 < x - 9 + 9 < 8 + 9

∴ 12 < x < 17

∵ There is no mention about the type of the number that is integer or

   rational number or real number

∴ The range of x is any number between 12 and 17

The range of the numbers make this true is (12 , 17)

Remember you can use any number between 12 and 17 but you

cannot use 12 or 17

The range of numbers that make this true is (12, 17).

Let the numbers be represented by x.

Therefore, based on the information given, the number will be:

x - 9 = 3

x = 3 + 9

x = 12

The first number is 12.

x - 9 = 8.

x = 8 + 9

x = 17

Therefore, the range of numbers that make this true is (12, 17).

Answer:

(5, 2), (14, -7), (5, -16), (-4, -7)

Step-by-step explanation:

There is an infinite number of possibilities. However, I suspect "they" are thinking of integral coordinates and equally spaced points.

In that case, you could move up nine units to (5, 2).

This puts eight points between A and B. I have numbered them in the diagram below.

Any point on a circle with radius 9 and centred at (5, -7) is 9 units from A, but only these four points have integral coordinates for themselves and for the points in between:

when we multiply the equation and subtract equatio 2 from equation 1 the result is 0=-4 and 0=2

Answer:  The correct option is

(B) no solution.

Step-by-step explanation:  We are given to find the solution of the following system of equations :

[tex]-2x-y=1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-4x-2y=-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

From equation (i), we have

[tex]-2x-y=1\\\\\Rightarrow y=-2x-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (ii), we get

[tex]-4x-2(-2x-1)=-1\\\\\Rightarrow -4x+4x+2=-1\\\\\Rightarrow 2=-1,[/tex]

which can never be possible.

Thus, the given system of equations have no solution.

Option (B) is CORRECT.

Answer:

b) 91

Step-by-step explanation:

Step 1: Multiple marks by its weights

Homework average: 95 x 20% = 19

Quiz average: 90 x 20% = 18

Test average: 87 x 40% = 34.8

Final exam: y x 20% = 0.2y

Step 2: Add all weighted averages and find y

19+18+34.8+0.2y = 90

71.8 + 0.2y = 90

y = 18.2/0.2

y = 91

Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.

Option b is correct.
