A man sold a calculator at a loss of 12℅. If selling price was Rs.7040, what was the cost price?​

Answers

Answer:

Rs.6195.20

Step-by-step explanation:

So first you need to find 12 % of Rs.7040. Thus:

[tex]\frac{12}{100}[/tex] × 7040 = 844.80

Then you subtract 844.80 from 7040 from which you get  Rs.6195.20

Rs.6195.20 was the cost price.

Given that f(x)=2x-8, determine the average rate of change over the interval [2, 8].

Answers

Answer:

2

Step-by-step explanation:

The average rate of change over [2, 8] is the change in the y-values over the change in the x-values.

[tex]\frac{f(8) - f(2)}{8 - 2}[/tex]

[tex]f(8) = 2(8) - 8 = 16 - 8 = 8[/tex]

[tex]f(2) = 2(2) - 8 = 4 - 8 = -4[/tex]

[tex]\frac{8 - (-4)}{8-2} = \frac{8 + 4}{8-2} = \frac{12}{6} = 2[/tex]

Answer:

The integers are

1st: n

2nd: n + 1

3rd: n + 2

The words in the problem statement translate into

2(n + 1) = 3(n + 2) + 6

Solve for n.

2n + 2 = 3n + 12

n = -10

n + 1 = -9

n + 2 = -8

Step-by-step explanation:

Two-thirds a numberx plus 4 is 8.

Answers

Answer:

n = 6

Step-by-step explanation:

To solve this you can use an equation such as:

[tex]\frac{2}{3} n+4=8\\\\[/tex]

We need to so for n. Subtract 4 from both sides to get the variable (n) alone. 4 - 4 and 8 - 4 equals:

[tex]\frac{2}{3}n=4[/tex]

So now we divide both sides by 2/3.

This now equals:

[tex]n=6[/tex]

4. Find the equation of the lines described.
A. Find the equation of the line parallel to y = 3x -5
and passing through
(-4, 7).

Answers

Answer:

y = 3x + 19

Step-by-step explanation:

Apply point-slope form. Our point (y1, y2) is (-4, 7) and our slope (m) is 3. The slope of y = 3x - 5 is 3 because it is "m" in y = mx + b. Parallel lines have the same slope.

y - y1 = m(x-x1)

y - 7 = 3(x-(-4))

y - 7 = 3(x+4)

y - 7 = 3x + 12

y = 3x + 19

Junaid has a rectangular box open from the top as in the figure. He paints base and 4 lateral faces as shown. He paints only up to th of the height of the box to save paint. Find the total surface area he painted.

Answers

The surface area is the total area occupied by the object. The surface area of the painted figure is [tex]440m^2.[/tex]

From the attached box, we have the following:

[tex]L = 20m[/tex] -- length

[tex]W = 10m[/tex] --- width

[tex]H = \frac 45 \times 5m = 4m[/tex] --- the painted height

Since the box has an open-top, the surface area is:

[tex]Area = LW + 2(WH + LH)[/tex]

So, we have:

[tex]Area = 20 \times 10 + 2 \times (10 \times 4 + 20 \times 4)[/tex]

[tex]Area = 200 + 2 \times (120)[/tex]

[tex]Area = 200 + 240[/tex]

[tex]Area = 440[/tex]

Hence, the painted area is [tex]440m^2.[/tex]

If f(x) = ax + b represents a linear function, describe the a and b values that produce a constant function?

Answers

In f(x)=ax+b, 'a' is the slope and b is the initial value or y intercept

Given :

Given function is f(x)=ax+b

f(x)=ax+b is the linear equation

The graph of a linear equation is a line. The value of 'a' tell us the steepness of the line that is the slope of the line .

'b' is the initial value . when x=0, f(x)=a(0)+b

that is f(0)=b

Answers

Answer:

168000

Step-by-step explanation:

5/14 to the son.

that leaves 9/14 of the total.

these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.

how do we do that ?

well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).

but in general by multiplying. so 2/3 of 8/14 is

9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14

and then little surprising 1/3 is

9/14 × 1/3 = 9 / 14×3 = 3/14

now, we know, these 3/14 are 36000.

what we need to know is how much is 14/14 or 1/1 : the whole amount.

well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).

it in total, multiply it with the reverse fraction : 14/3

36000 × 14/3 = 12000×14 = 168000

Calculate the volume of a warehouse that has inside dimensions of 22.4 meters by 11.3 meters by 5.2 meters.

Answers

I think it should be 1316.22 cubic meters

The volume of the warehouse with the three dimensions is V = 1,316.224 cubic meters.

Given data:

To calculate the volume of the warehouse, you need to multiply its length, width, and height:

Volume = Length *  Width * Height

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Given the dimensions:

Length = 22.4 meters

Width = 11.3 meters

Height = 5.2 meters

Substitute these values into the formula:

Volume = 22.4 m × 11.3 m × 5.2 m

Calculate the result:

Volume = 1,316.224 m³

So, the volume of the warehouse is approximately 1,316.224 cubic meters.
