I WANT SOLUTION AND EXPLANATION ANSWER IS GIVEN AT LAST!!!

<h3><u>Question</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. If the sum of the digits of the original number is 13, then find the number. </u>

<h3><u>Statement</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. </u><u>T</u><u>he sum of the digits of the original number is 13</u><u>.</u>

<h3><u>Solution:</u></h3>
  • Let one of the digit of the original number be x.
  • So, the other digit = (13-x)
  • Therefore, the two digit number = 10(13-x) + x = 130-10x+x = 130-9x
  • The number obtained after interchanging the digits is 10x+(13-x) =9x+13
  • Therefore, by the problem

130-9x-(9x+13) = 45

or, 130-9x- 9x-13 = 45

or, -18x = 45-130+13

or, -18x= -72

or, x = 72/18 = 4

or, x = 4

  • So, the original number = 130-9x = 130 -9(4) = 130 - 36 = 94
<h3>Answer:</h3>

The number is 94.

I think the answer you have given isn't right. The answer should be 94.

How do you find the radius when given the volume and height? ​
Eduardwww [97]

Answer:

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume. SOO just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

Step-by-step explanation:
