Answer»

Step-by-step explanation:

we know that 1 kg = 1000g

then, 4×1000+500= 4500gm

on dividing 8×1000gm = 8000gm by 4500kg we get,

quotient = 1 remainder = 35

Answer» Set 1 (10 cm, 26 cm, 24 cm) Step-by-step explanation: As we know, In a right-angled TRIANGLE, the hypotenuse is the LONGEST side and Hypotenuse^2 = Base^2 + Perpendicular^2 Let 26cm be the hypotenuse and 10cm and 24CM to be the base and perpendicular respectively, 26^2 = 10^2 + 24^2 676 = 100 + 576 676 = 676 Hence, set 1 is the correct set of side lengths for a right triangle.

4.

Which of these four sets of side lengths will form a right triangle?

Answer»

Set 1 (10 cm, 26 cm, 24 cm)

Step-by-step explanation:

As we know,

In a right-angled TRIANGLE, the hypotenuse is the LONGEST side and

Hypotenuse^2 = Base^2 + Perpendicular^2

Let 26cm be the hypotenuse and 10cm and 24CM to be the base and perpendicular respectively,

26^2 = 10^2 + 24^2

676 = 100 + 576

676 = 676

Hence, set 1 is the correct set of side lengths for a right triangle.

5.	The cost of 12 oranges is equal to the selling price of 15 oranges. Find the loss or gain percent?
Answer» Hyy Dude Given That: Selling price of 12 ORANGES = Cost price of 15 oranges Solution: Let the CP be ₹100 per orange. CP of 15 oranges = 15 × 100 = ₹1500. Then according to the given condition, we get SP of 12 oranges = ₹1500 Therefore, SP of 1 orange = 1500/12 = ₹125 Therefore, PROFIT = SP of 1 orange - CP of 1 orange = 125 - 100 = ₹25 Therefore, Profit Percentage = (25/100) × 100 = 25% Hence, Profit is 25% Hope you got it!.

5.

The cost of 12 oranges is equal to the selling price of 15 oranges. Find the loss or gain percent?

Answer»

Hyy Dude

Given That:

Selling price of 12 ORANGES = Cost price of 15 oranges

Solution:

Let the CP be ₹100 per orange.

CP of 15 oranges = 15 × 100 = ₹1500.

Then according to the given condition, we get

SP of 12 oranges = ₹1500

Therefore, SP of 1 orange = 1500/12 = ₹125

Therefore, PROFIT = SP of 1 orange - CP of 1 orange = 125 - 100 = ₹25

Therefore, Profit Percentage = (25/100) × 100

= 25%

Hence, Profit is 25%

Hope you got it!.

The first six players together score 5 times the total score of the remaining playersandiii. The average score of all eleven players is 30.Find the score of sixth batsmanplease let me know the answer of this Q

Answer»

1 )Given Number of players = 11,

Average score of 11 players = 30

Sum of the SCORES of 11 players = 11× 30

= 330 ---(1)

2 ) Let sum of the first 5 players score = x

sum of the remaining 6 players score = y

/* According to the problem given */

x = 4y ----(2)

Total score = 330 [ From (1) ]

=> x + y = 330 ---(3)

=> 4y + y = 330 [ From ( 2) ]

=> 5y = 330

=> y = 66 ---(4)

/* Put y = 66 in equation (3), we get */

x + 66 = 330

=> x = 330 - 66

=> x = 264 --(5)

3) Let Score of 6th batsman = K

x + k = 5(y-k)

=> x + k = 5y - 5k

=> 6k = 5y - x

=> 6k = 5×66 - 264 [From (4) and (5) ]

=> 6k = 330 - 264

=> 6k = 66

=> k = 11

Therefore.,

$\red { Score \:of \:the \:6th \:<klux>BATSMAN</klux>} \green {= 11 }$

Answer» Answer: The square root of 2 is equal to the length of the hypotenuse of a right triangle with legs of length 1 The square root of 2, or the (1/2)th power of 2, written in mathematics as √2 or 21⁄2, is the positive algebraic number that, when multiplied by itself, EQUALS the number 2. Technically, it is CALLED the principal square root of 2, to distinguish it from the negative number with the same property. Geometrically the square root of 2 is the length of a diagonal across a square with sides of one unit of length; this follows the Pythagorean theorem. It was probably the first number known to be irrational.[citation needed] As a good rational approximation for the square root of two, with a reasonably small DENOMINATOR, the fraction 99 / 70 (≈ 1.4142857) is sometimes used.
