The hundreds digit and the ones digit of a three digit number are the same. the sum of its tree digits are 16. if the tens digit and the ones digit are exchanged, the number increases by 45. what is the number?

Step-by-step explanation:

       Let us denote the three digit number by , where is the hundreds digit, is the tens digit and is the ones digit.

       Hundreds digit = = Ones digit =

       Sum of digits =

       So,

       On exchanging tens and ones digit, value increases by 45. So is 45 greater than .

∴ Required number is 727

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction
