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%
