First, we determine the area of the rectangular house by multiplying the length by the width. That is,
area of the house = (50 ft)(24 ft) = 1200 ft²
Given that all sides of the house should have the pathway, the length of the house plus the pathway should be 50+2x and the new width would be 24+2x. The new area minus the original area of the house should not be more than 345 ft². Thus, the equation would be,
(50+2x)(24+2x) - 1200 ≤ 345
-8400/68 simplifies to to -2100/17, dolphins/year, so 2100 less dolphins every 17 years.
and we can just divide those to get the decimal amount of -123.53, which means, 123.53 less dolphins every year.
of course, there's no such a thing as 0.53 of a dolphin, so, we can say "about" 123 less dolphins per year.

Step-by-step explanation:
We have been given that, in a cricket match, a batsman hits a boundary 6 times out of 30 balls he plays and we have to find the probability of not hitting boundary. So, the probability of hitting boundary⇒Number of boundaries hitTotal number of balls=630=15.
Well, the answer to this question is X = 24.

Answer:
about 1.4 hours
Step-by-step explanation:
3.13 gallons per minute.
60 minutes in an hour, so multiply both numbers by 60.
187.8 gallons per hour.
Divide the number of gallons we need to fill the tub the number of gallons put in per hour.
255÷187.8=1.375...
Round it, you get 1.4 hours.
It takes about 1.4 hours to fill the hot tub.
