A plane leaves jfk international airport and travels due west at 570 mi/hr. another plane leaves 20 minutes later and travels 22

olga2289 [7]

Distance=speed*time
distance traveled by plane A after 40 minutes:
distance=570×40/60=380 miles

Distance traveled by B after 40 minutes
distance=20/60×585=195 miles

Thus the distance between them will be given using cosine law:
c^2=a^2+b^2-2ab Cos C
thus we shall have:
c^2=380^2+195^2-2*380*195*cos22
c^2=45016.35275
c=212.171 miles
Thus the distance between them after 40 minutes is 212.171 miles

The glass container is filled to a height of 2.25 inches. What percent of the container is filled with sand?

Makovka662 [10]

The complete question in the attached figure

Part A) How much sand is currently in the container?
[sand currently in the container]=(5)*(4 1/2)*(2.25)-----> (5)*(4.5)*(2.25)
[sand currently in the container]=50.625 in³

the answer Part a) is 50.625 in³

Part B) How much more sand could the container hold before?
[sand could the container hold before]=[5*4.5*3]-[50.625]
[sand could the container hold before]=[67.5]-[50.625]------> 16.875 in³

the answer Part B) is 16.875 in³

Part C) What percent of the container is filled with sand?
the volume of container is [5*4.5*3]=67.5 in³
the volume filled with sand=50.625 in³
therefore
if 100%----------------> 67.5 in³
X---------------------> 50.625 in³
X=(50.625*100)/67.5=75 %

the answer Part C) is 75%
