The answer is 125. 40x2 is 80, 50x2 is 100, 20 percent left, 20 is half of 40, half of 50 is 25, 100+25=125.
Answer:
rational
Step-by-step explanation:
it's rational because a rational number * a irrational number is always irrational. a rational number times a rational number = a rational number. here are examples:
case 1 irrational times rational:
root two * 4 = 5.65685424949
case 2 rational times rational
8 * 5 = 40
Multiply the two values together. 7.62 x 1.23 = 9.3726
10^2 x 10^4 = 10^6.
9.3726 x 10^6 is the answer in Scientific Notation.
