Answer:
430
Step-by-step explanation:
<u>Given :-</u>
- By selling a watch on 400 and 460’. Loss and profit happened respectively.
- The loss and profit are equal.
And we need to find out the CP .So ,
<u>Let :- </u>
- CP be x
- Profit and Lost be y .
<u>According to the Question :- </u>
460 = x + y <em>( Profit)</em>
400 = x - y <em>( Loss)</em>
<u>Adding both :- </u>
460 + 400 = x + y + x - y
860 = 2x
x = 860/2
x = 430
<u>Hence the Cost price of the watch is 430 .</u>
Answer:
150 ft
Step-by-step explanation:
The diagram shown gives us a picture of two similar right triangle.
The height of the man is similar to the height of the platform.
To find the height of the platform, multiply the height of the man by the scale factor.
Scale factor = the ratio of any corresponding sides of two similar triangles.
Scale factor = 100 ft ÷ 4 ft = 25
Height of man = 6ft
Therefore, height of platform = 6 ft × 25 = 150 ft
Yes, a quadratic model does exist and its equation is f(x)=4x^2
The figure consists of a triangle and two rectangles.
-----------------------------
Top Triangle:
-----------------------------
Height = 22 - 10 - 7 = 5cm
Base = 20 - 5 - 5 - 10cm
Area of triangle = 1/2 x 5 x 10 = 25 cm²
-----------------------------
Middle Rectangle:
-----------------------------
Length = 10cm
Width = 7cm
Area = 10 x 7 = 70 cm²
-----------------------------
Bottom Rectangle:
-----------------------------
Length = 20 cm
Width = 10 cm
Area = 20 x 10 = 200 cm²
-----------------------------
Total Area:
-----------------------------
Area = 25 + 70 + 200 = 295 cm²
-----------------------------
Answer: Area = 295 cm²
-----------------------------
