The answer is one.
The answer to anything to the power of zero is one.
+7-8= -1
-7+8= 1
-7-8= -15
-7+8 = 1
Always remember that
2 negatives (minus negative something) is positive
2 positives (plus positive something) is positive
1 negative and 1 positive is negative
Good Luck :)
We multiply the numerators by each other. This will be the numerator for the answer. 9 x 1 = 9
We repeat the first step for the denominator. 14 x 6 = 84
Then we put them together. 9/84
Lastly we simplify 3/28
I agree XD
1.98855 × 10^30 kg
You're welcome :D
You'll rip through the fabric of time and space, effectively destroying the universe.
Sorry, I had to.
The answer is a.
Explanation:
Complementary angles are two angles that add up to 90 degrees.
So (3x-10) + (2x+10) would have to equal 90 (3x-10) + (2x+10) = 90
We simplify it. The 10s cancel each other out 3x - 10 + 2x +10 = 90
5x = 90
We simplify again x = 18
First, we expand the brackets 3/10x + 6/10 (simplified form is 3/5) = 5
Then we would move the 6/10 to the other side. 3/10x = 4 4/10
We would then multiply both sides by 10 3x = 44
Then we divide both sides by 3 x = 14.67
To calculate a percentage you must divide the amount out of the total and multiply it by the total. For this question you would have to do 94/640 = 0.146 0.146 x 100 = 14.6%
