The top of a 25-foot ladder is sliding down a vertical wall at a constant rate of 3 feet per second. When the top of the ladder is 7 feet from the ground, what is the rate at which the distance between the bottom of the ladder and the wall is changing in feet per second?

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
