A three-digit number has tens digit two greater than the units digit and the hundreds digit one greater than the tens digit. The
Paha777 [63]

Answer:

875

Step-by-step explanation:

As given, there is a three digit number

So, let assume three digit number be `xyz`.

Now, as given tens digit is 2 greater than the unit digit.

∴ y= 2+z

Next, the hundred digit one greater than the tens digit.

∴x= 1+y

The sum of the tens and the hundreds digits is three times the units digit.

∴x+y= 3z

Now, substituting the value in the equation.

x+y= 3z

⇒ (1+y)+y= 3\times (y-2)

solving it to get value of y

⇒ 2y+1= 3y-6

⇒-y= -7

∴ y=7

Next, finding value of z

y= 2+z

substituting the value of y and subtracting both side by 2

∴ z= 7-2= 5

Last, finding the value of x

x=1+y

substituting the value of y

∴ x= 8

xyz= 875

The leg of a right triangle is 2 units and the hypotenuse is 5 units. What is the length, in units, of the other leg of the tria
AVprozaik [17]
For this question, we have to use the Pythagorean theory since we're dealing with a right triangle.

a² + b² = c²

We're given the value of the hypotenuse and a leg, therefore we're looking for the value of the other leg.

Now let's plug in the given data into our equation.

2² + b² = 5²
4 + b² = 25
b² = 25 - 4
b² = 21
√b² = √21 = b

The correct answer is B) √21
