20 x 85% = 17. She should make 17 shots.
If the measure of an angle "θ" is 7(π/6), then it's equivalent measurement in degrees is 210°.
As per question statement, we have an angle "θ" whose measurement in radians is 7(π/6). We have to convert this radians into its equivalent measurement in degrees. Thus, to solve this question, we will have need to know the relation between radians and degrees, which goes as,
("π" Radian = 180°).
Then, we will apply unitary method to our provided data and use the above-mentioned relation to obtain our desired answer, i.e.,
π Radian = 180°,
then, 7π Radian =
°,
Then, 7(π/6) Radian =
°.
- Radian: This is an unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
- Degrees: This is another unit of measurement of angles, one unit of this being equal to one three-hundred-and-sixtieth of the circumference of a circle.

Answer:
We conclude that 49x² - 28x + 4 = 0 has only one real root.
Thus, option B i.e. one real root is the correct option.
Step-by-step explanation:
Given the equation
49x² - 28x + 4 = 0
comparing with the quadratic equation ax² + bx + c = 0 for x, where a ≠ 0,
here
a = 49, b = -28, c = 4
Determining the discriminant b²-4ac
b²-4ac = (-28)² - 4(49)(4)
= 784 - 784
= 0
It is clear that the discriminant b²-4ac is equal to zero.
i.e.
b²-4ac = 0
We know that if the discriminant b²-4ac = 0, then the quadratic equation has one real root.
Therefore, we conclude that 49x² - 28x + 4 = 0 has only one real root.
Thus, option B i.e. one real root is the correct option.
Let H = Henry
Let R = Roger
Let S = Sandy
H = 3R -> H = 3y
S = 9 + H -> S = 9 + 3y
R = y
Sandy has 3y + 9 CDs more than Roger.
