Answer:
an=7.35+ 0.33(n-1)
Step-by-step explanation:
The relationship between women's whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of n.
We are given values for n=7 and n=12 as a7=9.33 and a12=11
So, we proceed from the options and check which an satisfies these values:
an = 7.35 + 0.33(n-1)
when n = 7:
an = 7.35 + 0.33 (7-1)
an = 9.33
when n = 12:
an = 7.35 + 0.33 (12-1)
an = 10.98≈11
Hence, correct option is:
an=7.35+ 0.33(n-1)

Answer: 16,425 gallons are wasted a year
Step-by-step explanation:
First find out how many minutes there are in a year then multiply it by how much oz the faucet leaks every years then convert it into gallons.
There are 525,600 minutes in a year now multiply it by 4.
525,600 * 4 = 2,102,400 So there are more than 2 million oz wasted in a year so now convert it to gallons.
If there are 128 oz for every gallons the divide 2,102,400 by 128 to find out how many gallons are wasted a year.
2,102,400 / 128 = 16,425
The faucet wastes 16,425 gallons of water in a year by leaking 4 oz. per minute. This is calculated by first determining the total ounces of water wasted in a year, and then converting it into gallons.
The question wants to know how many gallons of water are wasted in a year by a faucet that leaks 4 oz. of water per minute. To solve this, let's first convert everything into consistent units, and then use simple multiplication to find the answer.
First, remember that there are 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Thus, the faucet wastes 4 * 60 * 24 * 365 = 2,102,400 ounces of water in a year.
Now, convert this to gallons. We know that 1 gallon = 128 ounces. Therefore, the faucet wastes 2,102,400 / 128 = 16,425 gallons of water in a year.
