Which number has one digit that represents 10 times the value of the digit to it's right? 375,595, 545,150 and 378,658

The required number is : 375,595

Step-by-step explanation:

The given numbers are : 375,595, 545,150 and 378,658

We have to tell the number that has one digit that represents 10 times the value of the digit to it's right.

For this we need to look for the number that has two same digits together, because only then the left digit will be 10 times the right digit.

Only the number 375,595 has two 5's together where the left one is 10 times the right one.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
