The pool leaks 7/8 of a gallon in 1/2 hour. Times that by 2 to find out how many gallons per hour. 7/8 x 2 = 14/8 = 1 and 3/4 gal/hour. (1.75 gal/hour)
I'm pretty sure he saved $27. I just divided 90 by 20 to get the amount of times he would have saved 6 dollars. Then, I multiplied that number, 4.5, times 6 to get the amount he saved. Hope that helps (and that it's correct lol). <span />
Answer:
Explanation:
In the given geometric sequence:
We see that:
• The first term, c1 = 4
Also:
• The common ratio, r= -1/3
The explicit formula for a geometric function is obtained using the formula:
Substituting a (the first term, c(1)) and r, we have the explicit formula below:
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
