Answer:

A

Step-by-step explanation:

Given 60% of students passed , then 40% of students failed.

60% = 180 ( divide both sides by 60 )

1% = 3

Then

40% = 40 × 3 = 120

120 students failed the exam

Let's say you had a cake that is cut into 5 equal slices. Then someone eats 2 of those slices. They ate 2/5 of the cake.

Now let's say you have another cake that you cut into 10 equal slices. If someone eats 4 of those ten, then they have eaten 4/10 = 2/5 of the cake.

Check out the diagram below to see a visual of how 4/10 and 2/5 are equivalent fractions.

Going from 2/5 to 4/10 has us multiply top and bottom by 2.

-----------

Similarly, 1/2 = 5/10 after multiplying top and bottom by 10

The original expression 2/5 + 1/2 turns into 4/10 + 5/10

Then you add the numerators to get 4+5 = 9, placing that over the common denominator of 10

<h3>Answer: 9/10</h3>

Describe what solving a trigonometric equation is.
AleksAgata [21]
That's an awfully broad question.  Could you not be more specific?

A basic example:  Suppose you are told that sin theta = 1/2.  Solving this equation would require finding the measure of the angle theta.  In this case the answer would be "30 degrees," or "pi/6 radians."
