7.	What if we through a steel ball and a rubber ball on ground at the same time which will bounce higher.. I need a clear explaination.. and also think about this.. we have saw that rubber ball bouncing.. but not the steel ball... even you can't imagine that... And now give me a clear explaination that which bounces higher with explaination
Answer» AnsWer :- The key to this explanation is the 'stored energy'. When a rubber ball hits a surface, it COMPRESSES SLIGHTLY and then snaps back to its original shape. When a STEEL ball hits the ground, it snaps back faster because a steel ball is better at storing energy than a rubber ball, which GIVES it a lot of bounce power. Also, we can do it PRACTICALLY and the observation will be - The steel ball bounces higher than a rubber ball. Note that when we drop these balls on a hard surface, the observation will remain the same.

8.	Hasan buys two kinds of cloth material for school uniform shirt material that cost in rupees 50 per metre and trouser material that cost in rupees 90 per metre for every three of the shirt material he buys 2 metre of the trouser material he sells the material at 12% and 10% profit respectively is total sale is 36600 how much trouser material did he buy.tell me the answer with explanation please
Answer» Step-by-step explanation: LET Hasan BOUGHT 2X m of trouser material and 3X m of the shirt material. Per metre selling price(S.P) of the trouser material = ₹90+90×12/100 = 90 + 1.2× 9 = 90 + 10.8 =₹100.80 Per metre selling price(S.P) of trouser of shirt material = ₹50+ 50× 10/100 = ₹ 50 + 5 =₹55 Given: total amount of sale= ₹ 36660 100.80 x (2x) + 55 x (3x) = ₹36660 201.60 x + 165x = 36660 366.60 x = 36660 X= 36660/366.60 x = 100 Trouser material = 2x m = (2×100)m = 200m. Hasan bought 200 m of trouser material.

Hasan buys two kinds of cloth material for school uniform shirt material that cost in rupees 50 per metre and trouser material that cost in rupees 90 per metre for every three of the shirt material he buys 2 metre of the trouser material he sells the material at 12% and 10% profit respectively is total sale is 36600 how much trouser material did he buy.tell me the answer with explanation please

Answer»

Step-by-step explanation:

LET Hasan BOUGHT 2X m of trouser material and 3X m of the shirt material.

Per metre selling price(S.P) of the trouser material = ₹90+90×12/100

= 90 + 1.2× 9

= 90 + 10.8

=₹100.80

Per metre selling price(S.P) of trouser of shirt material

= ₹50+ 50× 10/100

= ₹ 50 + 5

=₹55

Given: total amount of sale= ₹ 36660

100.80 x (2x) + 55 x (3x) = ₹36660

201.60 x + 165x = 36660

366.60 x = 36660

X= 36660/366.60

x = 100

Trouser material = 2x m = (2×100)m = 200m.

Hasan bought 200 m of trouser material.

Maximum marks marked as brainliest ans irrevelent answer will be reported

Answer»

(a+b+c)² = (-a-b+c)²

x³ + y³ = (x+y)(x²-xy+y²)

(a+b)² + (a-b)²

= (a²+b²+2AB) + (a²+b²-2ab)

= a²+b²+2ab + a²+b²-2ab

34.	Define a square root.
Answer» ANSWER: In mathematics, a square root of a number X is a number y such that Y2 = x; in other words, a number y whose square(the result of multiplying the number by itself, or y ⋅ y) is x. ... For example, the principal square root of 9 is 3, which is denoted by √9 = 3, because 32 = 3 ⋅ 3 = 9 and 3 is NONNEGATIVE.

45.	(a). What is the output if the input is 5?
Answer» Find the INPUT and output values of a function When we know an input value and want to DETERMINE the CORRESPONDING output value for a function, we evaluate the function. Evaluating will ALWAYS produce one result because each input value of a function corresponds to exactly one output value. When we know an output value and want to determine the input values that would produce that output value, we set the output EQUAL to the function’s formula and solve for the input. Solving can produce more than one solution because different input values can produce the same output value.
