Given data:
The given figure.
The major arc angle is 300 degree, it means the minor arc angle is 60 degree, so the triangle inscribed in the circle is equilateral triangle.
The expression for the area of the shaded region is,
![\begin{gathered} A=\frac{60^{\circ}}{360^{\circ}}(\pi)(7)^2-\frac{\sqrt[]{3}}{4}(7)^2^{} \\ =\frac{1}{6}(\pi)(7)^2-\frac{\sqrt[]{3}}{4}(7)^2 \\ =25.65-21.22 \\ =4.43 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D%5Cfrac%7B60%5E%7B%5Ccirc%7D%7D%7B360%5E%7B%5Ccirc%7D%7D%28%5Cpi%29%287%29%5E2-%5Cfrac%7B%5Csqrt%5B%5D%7B3%7D%7D%7B4%7D%287%29%5E2%5E%7B%7D%20%5C%5C%20%3D%5Cfrac%7B1%7D%7B6%7D%28%5Cpi%29%287%29%5E2-%5Cfrac%7B%5Csqrt%5B%5D%7B3%7D%7D%7B4%7D%287%29%5E2%20%5C%5C%20%3D25.65-21.22%20%5C%5C%20%3D4.43%20%5Cend%7Bgathered%7D)
Thus, the area of the shaded region 4.43 sq-units.
Answer:1/5
Step-by-step explanation:
It’s goes 1/5 per time
The answer that you're looking for is B
"Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week." because.
Let n be the number of aerobic and strength-training exercises per week.
Let x be the number of strength-training exercises per week on the beginner
15x + 20n = 90
Let y be the number of strength-training exercises for week on the advanced plan.
20y + 30n = 130
Multiply both sides by 1.5, to get:
22.5x + 30n = 135
Subtracting equation 2 from 3 we get:
22.5x - 20y = 5
