There are 25+17=42 white/blue cards, and 21+9=30 silver/red cars. Then, we have a difference of 42-30=12 cars.
3.25 * 7.8 = 25.35
10^3 * 10^6 = 10^(3+6) = 10^9
so we have 25.35 * 10^9 but in scientific notation the first number mus be <10
so the answer is 2.535 * 10^10
Answer:
5040
Step-by-step explanation:
"organism" has 8 letters. Since the g is not to be permutated, let's take it out, and we're left with 7 letters.
For the first position we have 7 options. For the second position we have 6 options, etc., so 7*6*5*4*3*2*1 = 7! = 5040.
The "g" we just insert at the 3rd position, it doesn't play any role in the counting.
