1.53 rounded to the nearest tenth is 1.5
The probability that the train will be there when Alex arrives is 5/18
If Alex arrives at any time after 1.20pm the chances that train will be there is 1/3.
However if alex arrives at 1.00pm exactly there is no chance the train will be arrive there.
The probability that the train will be there increase linearly to 1/3 as alex's arrival time moves from 1.00pm to 1.20pm.
By arranging the probabilities over the first 20 minutes to get a 1/6 chance the train will be there if alex arrives between 1.00pm to 1.20pm
we get the final answer by
=1/3( 1/6 + 1/3 + 1/3)
=5/18
So, the probability that the train will be there when Alex arrives is 5/18

To answer this you’d have to use an 2 step equation 145x= 1000
When u get the answer for x multiply the answer by the erasers original area to find the area of the eraser it would be lengthtimes width times height
-4.5 or -4.3 i’m not really sure i’m just estimating
Perimeter of a square=4*side length
160=4*side length
40=side length
Therefore, 39.99999 (repeating 9s) is the maximum side length in feet for the perimeter to be less than 160. If it was 40 feet as the side length, then it would not be less than 160.
Hope this helps!
