The cost price of a box and a pen is Rs 80 The box is sold at 10% profit and the pen is sold at 20% loss. If the selling price of the box is Rs 28 more than that of the pen, calculate the profit or loss percent in a whole. ​

Answer:

x^2.

Step-by-step explanation:

(x+3)^2 -3 (2x+3)

= (x + 3)(x + 3) - 3(2x + 3)

= x^2 + 3x + 3x + 9 - 6x - 9

= x^2 + 6x + 9 - 6x - 9      

= x^2 + 6x - 6x + 9 - 9        Simplify like terms:

= x^2.

Answer:

If he can spend $400 +- $50 ($350 or $450) the maximum number of guests at $25 each is 18 and the minimum is 14. If there can be up to 7 guests, he should prepare to have at least 3 tables to ensure everyone gets a seat if he goes with the $450 option.

Step-by-step explanation:

Please mark Brainliest if this helped :)

Division is one of the four fundamental arithmetic operations. The minimum number of tables Ashton should reserve so everyone has a seat is 2.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Ashton's budget is $400±50. Therefore, the maximum and the minimum budget that Ashton can spend on the banquet are,

Maximum budget = $400 + $50 = $450

Minimum budget = $400 - $50 = $350

A.) Now, the maximum guest will cost the maximum budget, therefore, we can write

Maximum guest = Maximum budget / Budget per guest

                           = $450 / $25

                           = 18

Minimum guest = Minimum budget / Budget per guest

                           = $350 / $25

                           = 14

B.) Since the minimum number of guests that can come to the banquet is 14, and only 7 people can seat at a table, therefore, the minimum number of tables Ashton should reserve so everyone has a seat is 2.

The perimeter of the triangle will be 5 + √17.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. The sum of all the sides of the triangle will be known as the perimeter of the triangle.

A triangle DEF with vertices D (3,2), E (4,2), and F (3,-2).

Distance between DE will be

DE² = (4 - 3)² + (2 - 2)²

DE² = 1

DE = 1

Distance between EF will be

EF² = (3 - 4)² + (-2 - 2)²

EF² = 1 + 16

EF = √17

Distance between DF will be

DF² = (3 - 3)² + (-2 - 2)²

DF² = 16

DF = 4

Then the perimeter of the triangle will be

P = DE + EF + DF

P = 1 + √17 + 4

P = 5 + √17

The perimeter of the triangle will be 5 + √17.

Answer:

2

Step-by-step explanation:

8 + 2 = 10, so basically, 10 - 8 = 2. Meaning the missing number to when 8 is added to something to equal 10, would be 2.

J (0 , -10)

gradient/slope(m) = 2.

We're asked to find K if K is the X- Intercept.

At the x intercept... the corresponding y value is zero. This concept should be pretty clear.

Reason is...

At the Point where the line touches the x axis...If you trace the y value... It will be at point zero(0).

With this Knowledge

We're able to interprete that the points of K is

(x" , 0)

Where x" represents the x coordinate of K

So

J ( 0, - 10)

K ( x" , 0)

m= 2.

Applying the Gradient/Slope Formula

m = y₂ - y₁/x₂ - x₁

x₁ = 0 y₁ = -10

x₂ = x" y₂ = 0

Substituting

2 = 0 - ( -10)/ (x" - 0)

2 = 10/x"

x" = 10/2

x" = 5.

Coordinates of Point K is ( 5 , 0).

Total Time Taken = 16secs

10a). We're asked to calculate the rate of speed change for the first 5secs.

This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.

Why?

Acceleration is the rate of change of speed or the rate at which speed changes.

acceleration = v - u/t

where v = Final Speed

u = initial Speed.

Looking at the graph

You see that

Initial speed(u) = 1m/s

Final Speed(v) = 9m/s

t = 5secs

Acceleration = 9 - 1/ 5

a = 8/5

a = 1.6m/s².✅

10b)

We're asked to calc "t" from the graph.

Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².

This simply means that Constant Acceleration was held from "t" to the end of the Motion.

Do not confuse Constant Acceleration for Constant Velocity.

At Constant Velocity... Acceleration is zero(0)

At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.

Taking the same step as we used in calculating acceleration above

Given a= 2m/s²

a = v - u/∆t

Where ∆t means time change or difference.

From "t" to 16

The change in time is 16 - "t"

2 = 21 - 9/( 16 - t)

2 = 12/16-t

16-t = 12/2

16 - t = 6

t = 16 - 6

t = 10secs.✅

Answer:

The three numbers are 29, 31, and 33.

Step-by-step explanation:

Let's imagine that the three consecutive odd integers are 2x−1, 2x+1, and 2x+3. And we are told the sum is 93 right? So, let's equal the three numbers to 93.

2x − 1 + 2x + 1 + 2x + 3 = 93

6x + 3 = 93

     -3     -3

-----------------

6x = 90

/6    /6

----------------

x = 15

Now, plug in x into 2x−1, 2x+1, and 2x+3 to find the three numbers.

2x − 1                   2x + 1                 2x + 3

2(15) - 1                2(15) + 1             2(15) + 3

30 - 1                    30 + 1                 30 + 3

= 29                      = 31                      = 33

Answer:

x=8 y=4

Step-by-step explanation:

eliminate x: make x of two equation equal to each other

2(-3x+9y=12) : -6x+18y=24 ___[1]

-3(2x-8y=-16) : -6x+24y=48 ___[2]

[2]-[1]= 6y=24

substitute y to any equation;

2x-8y=-16

2x-8(4)= -16

2x= -16+32

2x= 16

Answer:

x=14 and y=6

Step-by-step explanation:

-3x+9y=12.............(i)×2

2x-8y=-16..............(ii)×3

Multiplying equation (i) by 2 and equation (ii) by 3 and adding (i) and (ii)

-6x+18y=12

6x-24y=-48

-----------------

0-6y=-36

or, -6y=-36

So,y=6

From (i)

-3x+9y=12

or,-3x+9×6=12

or,-3x+54=12

or,-3x=12-54

or,-3x=-42

So,x=14
