4 0

Answer:

7

Step-by-step explanation:

So I started with an equation (g for green variable, y for yellow variable, b for blue variable)

8g + 5y + 8b = ??

Because of the lack of variables, I'm not really sure how to tie in the 50%, 20%, and 30%. (It could be unnecessary information)

But going off the average number of items, you have 8 green, 5 yellow, and 8 blue. So you can add them together for 21. From here, you divide 21 by 3 to get your average, 7.

An umbrella is made by stitching 10 triangular pieces of clothes of 2 different colors, each piece measuring 9 cm, 40 cm and 41
malfutka [58]

Answer:

See below in bold.

Step-by-step explanation:

The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).

So the area of one piece = 1/2 * 9 * 40  cm^2.

The total amount of cloth  required for one umbrella = 10 * 1/2 * 9 * 40

= 1800 cm^2.

The total cost =  1800 * 0.25 = Rs 450.
