jekas [21]

Answer:

0.25 % loss.

Step-by-step explanation:

Let the cost of 1 watch be  rs x then the cost of the other is rs 400 - x.

Let the sp be rs y.

So we have:

y = x + 0.05x

y = (400 - x) - 0.05(400 - x)

y =  400 - x - 20 + 0.05x

y = 380 - 0.95x

So  x + 0.05x = 380 - 0.95x

2x = 380

x = 190.

and y = 190 + 0.05*190 = 199.5.

So the total selling price = 2 * 199.5 = rs 399

So final loss is [ (400-399)/ 400] * 100

= 0.25 %.

Answer:

4. x = 16.8

5. x = 35.98

Step-by-step explanation:

For both triangles that you need to work on, use the trigonometric function which is tan and you are dividing opposite by adjacent for the answers.

For number 4, the equation you are setting up is tan 35 = x/24.  Multiply 24 on both sides to get the answer which is 16.8 for the x side.

For number 5, the equation you are setting up is tan 17 = 11/x.  As a result on your calculator, you should get 35.98 for the x side.

Answer:

m = -3

Step-by-step explanation:

First, find two clear points:

(1, -2) (0, 1)

Then, use the slope formula:

m = <u>y2 - y1</u>

      x2 - x1

m = <u>1 - (-2)</u>

       0 - 1

   = <u>3</u>  = -3

     -1

m = -3

This means that the rise-over-run is -3 over 1, or 3 over -1.

Which means three down and 1 to the right, or 3 up and 1 to the left.

Slope is the steepness of the line.
