119/30 or 3.96 or 3 29/30
Explanation:
First write all numerators above the least common denominator (in this case 30)
Then calculate the sum or difference
If you would like to solve the inequation X - 9 > 6, you can calculate this using the following steps:
X - 9 > 6 /+9
X - 9 + 9 > 6 + 9
X + 0 > 15
X > 15
The correct result would be X > 15.
Answer:
19.63%
Step-by-step explanation:
The probability of scoring 8 points is the probability of getting a dart into the green circle.
That probability is equivalent to the area of the circle divided by the total area of the square board.
The area of the circle according to
, is
cm squared
The area of the whole square board is one side squared: 20 squared = 400 cm squared
The probability is therefore equal to
%
