An umbrella is made by stitching 10 triangular pieces of clothes of 2 different colors, each piece measuring 9 cm, 40 cm and 41
cm. How much clothes is required for the umbrella? If the cost of 1 cm square cloth is Rs. 0.25, find the total cost of the clothes.
1 answer:
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.

Step-by-step explanation:
i am not sure but that is what i got.
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
Just draw like the 2 hundredths, 4 tens, and 6 ones
And then draw 7 tens and 8 ones
Short answer = 20
Argument
Your chances of throwing a 6 = 1/6
Expected Throws = P(6) * Total Throws
Expected Throws = 1/6 * 120
Expected Throws = 20
Answer = 20 <<<<<
