Answer:
3.5% of 20, (0.035)*20, and 7% of 10
Step-by-step explanation:
Converting the mixed number (3 1/2) to a decimal yields 3.5, so 3.5% of 20 is correct.
3 1/2 is not equal to 3 1/2%, so 3 1/2 * 20 is not correct.
Converting the percentage to a decimal yields .035 which makes .35 too large, so (0.35) * 20 is not correct.
Changing the percentage to a decimal yields .035, so (0.035) * 20 is correct.
If you divide 20 by 2, you get 10, and if you multiply 2 by 3 1/2, you get 7. The 2 remains part of the expression, so it is equal to 3 1/2 of 20.
Answer:
311.41 degrees
Step-by-step explanation:
If 4 sin Ф = -3 and Ф is between 0 and 360 degrees, then we conclude that Ф must be either in Quadrant III or Quadrant IV (because the sine is negative).
Let's assume we're in Quadrant IV. Then sin Ф = opp / hyp = -3/4; that is, the opp side is negative and has length 3, and the hypo is positive 4.
According to the Pythagorean Theorem, (-3)^2 + x^2 = 4^2, or,
x^2 = 16 - 9 = 7.
Then x is either √7 or -√7.
To find the angle Ф, use the inverse sine function:
Ф = arcsin (-3/4). Using a calculator we get the angle -40.59 degrees, which corresponds to (360 degrees - 40.59 degrees), or 311.41 degrees. We can check this by finding the sine of 311.41 degrees; the result is -0.75, which matches "If 4sintheta = -3."
