Answer:
Step-by-step explanation:
4 cups of tea per minute.......lunch lasts 2 hrs.....there are 120 minutes in 2 hrs...so in 2 hrs, there will be (4 * 120) = 480 cups
and if there is 16 cups in 1 gallon, the caterer needs to bring :
480 / 16 = 30 gallons <==
we have

the solution is the interval -------> (3,∞)
therefore
the answer in the attached figure
Given: In the given figure, there are two equilateral triangles having side 50 yards each and two sectors of radius (r) = 50 yards each with the sector angle θ = 120°
To Find: The length of the park's boundary to the nearest yard.
Calculation:
The length of the park's boundary (P) = 2× side of equilateral triangle + 2 × length of the arc
or, (P) = 2× 50 yards + 2× (2πr) ( θ ÷360°)
or, (P) = 2× 50 yards + 2× (2×3.14× 50 yards) ( 120° ÷360°)
or, (P) = 100 yards + 2× (2×3.14× 50 yards) ( 120° ÷360°)
or, (P) = 100 yards + 209.33 yards
or, (P) = 309.33 yards ≈309 yards
Hence, the option D:309 yards is the correct option.
