Answer:

The number of ways you can get 2 kings from 4 kings times the number of ways you can get 1 queen out of 4 queens divided by the number of ways you can get any 3 cards out of 52 cards.

Or you can draw a king on the first draw and a king on the second draw and a queen on the third draw, or you can draw a kind on the first draw and a queen on the second draw and a king on the third draw, or you can draw a queen on the first draw and a king on the second draw and a king on the third draw.

Jane had a bottle filled with juice. At first she drank 1/5 of the juice in the bottle. After 1 hours she drank 1/4 of the juice

Butoxors [25]

X is the size of the bottle. So x/5 + (x/5)/4 + ((x/5)/4)/3 = 2/3 cups

x/5 + x/20 + x/60=2/3; (12x+3x+x)/60=2/3; 16x/60=2/3; (16x)3=(2)(60)
48x=120
x= $\frac{120}{48}$ = 2 $\frac{24}{48}$ = 2 $\frac{1}{2} }$

The bottle is 2 $\frac{1}{2}$ cups

If a vehicle travels 25x miles in 2 hours, what is the vehicle's average speed, in miles per hour.

il63 [147K]

Given that a vehicle travels 25 miles in 2 hours, determine the average speed of the vehicle in miles per hour.

Work:

In order to find the average mph of the vehicle, you have to divide the distance the vehicle travels in a certain period of time by that amount of time.

So, in this case, the vehicle traveled 25 miles in 2 hours, so you would divide 25 by 2.

25/2 = 12.5

That means, the vehicle is traveling at a speed of 12.5 mph.

Thus, the average speed of the vehicle is 12.5 miles per hour (mph).
