Complete question
A 29-meter ladder is sliding down a vertical wall so the distance between the top of the ladder and the ground is decreasing at 7 meters per minute. At a certain instant, the bottom of the ladder is 21 meters from the wall.
What is the rate of change of the distance between the bottom of the ladder and the wall at that instant(in meters per minute)
Answer:

Step-by-step explanation:
From the question we are told that
Slant height 
Change in Vertical height 
Horizontal length 
Generally in finding the distance form the top to the bottom of the wall it is mathematically given by




Generally solving for the differential equation is mathematically represented as







53 times .07 is 3.71
53 times .15 is 7.95
You add those and get $64.66.
Answer:

Step-by-step explanation:
There are two scenarios:
A - Rain
B - Fog.
The probability of rain or fog is determined by the Addition Rule, given that A and B are not mutually excluyent:



Hey there,
The largest fraction out of the three would be 3/4.
Hope I helped :)
The answer to 3 is C, because 18+15 is 33, and 33 divided into three equal groups would have 11 in each.
The answer to 4 is A, because in 11/3 3 can go into 11 3 times, with 2/3 remaining.
