Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

v_A=\dfrac{300}{4}\\\\v_A=75\ mph

Speed of Truck B,

v_B=\dfrac{240}{3}\\\\v_B=80\ mph

Speed of Truck C,

v_C=\dfrac{325}{5}\\\\v_C=65\ mph

Speed of Truck D,

v_D=\dfrac{170}{2}\\\\v_D=85\ mph

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.

Can someone help me please
exis [7]

Answer:

43.7 ft

Step-by-step explanation:

Radius of the semicircular garden is 8.5 ft .

Diameter = 8.5 × 2 = 17 ft

Circumference of the garden = \frac{1}{2} × π × diameter = \frac{1}{2} × π × 17 = 26.7 ft (rounded up to the nearest tenth of a foot)

Distance around the gardent = Circumference + diameter = 26.7 ft + 17 ft =  43.7 ft
