The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at

30 miles per hour, how long will it take to drive the same distance at 50 miles per hour?

Distance = r x t ===> t=d/r

Distance (after 2 hours driving @30mil/hr) = 2 x 30 = 60 Mil

To drive same distance (60)  with r = 50, the time needed is 60/50 =1.2 hrs

A cone has a height 25 ft and a radius of 7 ft. Is a reasonable that the volume of this cone is 100 ft3? Why or why not?​
Nostrana [21]

Answer:

No

Step-by-step explanation:

the radius squared is 49 times π, which is roughly 3 means the area of the base is roughly 150 ft².

This means that one third of the height cannot be more than 100 / 150 = 2/3 of a foot. That makes the height about 2 ft, much less than the reported 25 ft.

Choose the ratios for sin A and cos A.
Irina18 [472]

Answer: D


Step-by-step explanation: By using SOH for sin A, 'S' being sin, 'O' being opposite side of angle A and 'H' being the hypotenuse which is the longest part of the triangle you would find that 15 is opposite from Sin A and 17 the hypotenuse, 15/17.

For cos A you would use CAH, C= cos, A which is the adjacent of the triangle located next to angel A which is 8, and H= hypotenuse (also note that the hypotenuse never changes even if the angle may be different) CAH would be cos A = 8/17
