Answer:
Step-by-step explanation:
Given expression is,
First equalize the denominators of the fractions,
Now combine the fraction as a single fraction,
Since, we can not solve this fraction further, this will be simplified form of the given expression.
16/20
Simplified to 8/10
Again simplified to 4/5.
Multiply the area of the circle by the percentage:
60 square units x 50% = 60 x 0.50 = 30
50% 0f the circle id 30 square units.
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
The answer is A. If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil. Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
