Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)

0 divided 15=0 is your answer
Area of a sector (s) = radius (r) · θ (in radians)
First, convert 168° into radians using the proportion π = 180°
Next, plug in x for θ
s = r · θ
= 8 ·

= 23.457
≈ 24.0
Answer: C
Multiply to remove the fraction, then set equal to 0 and solve, n= 1 over 2
