Answer for the first one - it's complicated, but that maths is correct
I kind of cheated and did it a different way than they'd expect. By doing 24 squared, that gives you 576.
since both angles are 45 degrees, then the sides are equal lengths. Therefore x squared times 2 = 576.
Because of this, x squared = 576 divided by 2, which equals 288.
Therefore the square root of 288 = 12 square root 2
The Second Answer: 721,000
Given:
The given system of equation is:
To find:
The solution of given system of equations using subtraction.
Solution:
We have,
...(i)
...(ii)
First equation can be rewritten as
(Adding 2x on both sides)
...(iii) (Multiplying both sides by 2)
After subtracting (ii) from (iii), we get
This statement is false because . It means, there is no value of x and y for which the given system of equations are true.
Therefore, the given system of equations has no solution and the correct option is b.
The probability of picking an even card the first time was 5/10, now that you have 9 cards the probability went down to 4/9.
