Simply use a protractor. Remember, sometimes triangles can be impossible to draw with improper values!
Additive inverse of a number is the number that should be added to the number to result in zero.
Eg additive inverse of -2 is +2, because -2 + 2 = 0
Similarly additive inverse of - 10 1/4 is +10 1/4.
Answer:
Step-by-step explanation:
Assuming that you need to simplify the expression, below is the explanation to do it.
Given the following expression:
You need to decompose the radicand (The number inside the square root) into its prime factors:
Knowing that, you can rewrite the expression in this form:
Since , you must substitute it into the expression:
Now you need to remember the following property:
Then, applying that property, you get:i:
Finally, you must divide the numerator and the denominator by 3. So, you get:
There are 39 boys.
First you divide 4 into 52 because there are 3 boys for 4 girls.
Then you take the quotient, 13, and multiply by 3.
