Answer:

The selling price of each is Rs.5941

Step-by-step explanation:

Given

[tex]N = 80[/tex] ---- Cookers

[tex]CP = Rs. 5700[/tex] --- Cost Price

[tex]Transport = Rs.1280[/tex]

[tex]Profit = Rs.18000[/tex]

Required

Determine the selling price (SP) of each

First, calculate the total cost price:

[tex]Total = N * CP + Transport[/tex]

[tex]Total = 80 * 5700 + 1280[/tex]

[tex]Total = 457280[/tex]

Selling Price is calculated using:

[tex]Selling\ Price = Cost\ Price + Profit[/tex]

[tex]Selling\ Price = 457280 + 18000[/tex]

[tex]Selling\ Price = 475280[/tex]

So, the total selling price of the 80 cookers is: Rs.475280

The selling price of each is:

[tex]Each = \frac{475280}{80}[/tex]

[tex]Each = 5941[/tex]

The selling price of each is Rs.5941

Answer:

tan55 = x/43

x = tan(55) * 43

x = 61.4 cm

Step-by-step explanation:

The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

In a right triangle, the leg adjacent to an angle of 23° is 12 cm long. The triangle is given below.

Let 'x' be the opposite side of the angle 23°. Then the value of the variable 'x' is given as,

tan 23° = x / 12

Simplify the equation, then we have

tan 23° = x / 12

0.4244 = x / 12

x = 0.4244 · 12

x = 5.1 cm

The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.

Answer:

D. 22 square feet

Step-by-step explanation:

From what I can see of the measurements, I think the answer is 22 square feet. Divide the L into two rectangles: 8x2 for the top one gives you 16 square feet; 3x2 for the bottom one give you 6 square feet. Add 16 and 6 for the area of the entire shape. You get 22 square feet.

Hope it helps!

The other endpoint is (-3, -3).

Option A is the correct answer.

The distance between two points of a line is given as:

Distance =  [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]

Where (a, b) and (c, d) are the two endpoints.

We have,

Distance between the points = 8 units

One endpoint = (5, -3) = (a, b)

Another endpoint = (c, d)

Now,

Substituting the values.

Distance =  [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]

8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]

Now,

We have to check each point.

(-3,-3) = (c, d)

8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]

8 = [tex]\sqrt{(-3 - 5)^2 + (-3 + 3)^2}[/tex]

8 = [tex]\sqrt{(-8)^2[/tex]

8 = √64

8 = 8

This is true

(-3,-11) = (c, d)

8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]

8 = [tex]\sqrt{(-3 - 5)^2 + (-11 + 3)^2}[/tex]

This is not true.

(5,8) = (c, d)

8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]

8 = [tex]\sqrt{(5 - 5)^2 + (8 + 3)^2}[/tex]

This is not true.

(8,-3) = (c, d)

8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]

8 = [tex]\sqrt{(8 - 5)^2 + (-3 + 3)^2}[/tex]

This is not true.

Thus,

(-3,-3) is the other endpoint.

Step-by-step explanation:

Answer:

  5)  (x, y) = (10, -1)

  6)  (x, y) = (5, 6)

Step-by-step explanation:

5) y coefficients are opposites, so y can be eliminated by adding the two equations.

  (x -y) +(2x +y) = (11) +(19)

  3x = 30 . . . . . simplify

  x = 10 . . . . . . . divide by 3

Using the second equation, we can find y:

  2(10) +y = 19

  y = -1 . . . . . subtract 20

The solution is (x, y) = (10, -1).

__

6) The x-coefficients are the same, so we can eliminate the x-term by subtracting the second equation from the first. We choose to do it that way so the y-coefficient ends up positive.

  (-6x +6y) -(-6x +3y) = (6) -(-12)

  3y = 18 . . . . . . simplify

  y = 6 . . . . . . . . divide by 6

Using the first equation to find x, we have ...

  -6x +6(6) = 6

  x -6 = -1 . . . . . . . divide by -6

  x = 5 . . . . . . . . . add 6

The solution is (x, y) = (5, 6).
