When you write a decimal as a percent, you move the decimal point 2 places to the right because you multiply it by 100.
I hope this helps:)) !!

Answer:
The number is 53.
Step-by-step explanation:
If the digits are x and y where x is the first digit then we have the equations:
x + y = 8.........(1)
10x + y - (10y + x) = 18
9x - 9y = 18
Dividing through by 9:
x - y = 2..........(2)
Adding (1) and (2):
2x = 10
x = 5
and y = 8 - 5 = 3.
For 1:
Use pythagorean theorem because of the radius tangent theorem(point of contact = 90 degrees)
12 is the hypotenuse (the right angle points at the hypotenuse)
Therefore:
(9)^2 + (x)^2 = (12)^2
81 + x^2 = 144
Subtract 81 from both sides of the equation
x^2 = 63
Square root both sides to get rid of square on x and isolate the variable
The square root of 63 = 7.93 (roughly)
