Answer: The angle is in the second quandrant

Step-by-step explanation:

If sin of theta is greater than 0, the angle theta has to be in either the first or second quandrant. If tangent of theta is less than 0, it cannot be in the first or third quandrant. Therefore, we know the angle is in the second quandrant.

Sally bought the pizza shown above for lunch, which was cut into 10 equal slices.What percentage of the pizza did sally eat if s
Rashid [163]

Answer:

DM

Step-by-step explanation:

We can represent the pizza as 1. And every time we take a slice, we take percentage away. This pizza is cut up equally into 10 slices. So, if we take away a slice, we take away 1/10 of the pizza. What if Sally ate 6 slices? Same difference. She took away 6/10 of the pizza.

And to answer the question, "What percentage of the pizza did Sally eat if she had six slices?"

We will convert the 6/10 into a percentage. First convert the fraction into a decimal then into a percent.

To convert a fraction into a decimal, simply divide it's numerator by it's denominator.

6/10 = 0.60

And to convert a decimal into a percentage, move the decimal point two places to the right and change it into a % sign.

0.60 = 60%

So, the answer to this question C) 60%
