A faucet leaks 4 oz. of water per minute. How many gallons of water are wasted in a year? (128 oz. = 1 gallon)

Answers

Answer 1

Answer:

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

Answer 2

Answer:

Final answer:

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.

Explanation:

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.

Which is equivalent to 216 power of 1/3 ?

Answers

Answer:

Step-by-step explanation:

GIVEN :

$(216)^{(1)/(3) }$

Solution :

let

$(216)^{(1)/(3) }=x$

$216 = x^(3)$

$6^(3) = x^(3)$

⇒ x = 6

⇒ $(216)^{(1)/(3) }= 6$

Answer:

Option (b) is correct.

$(216)^{(1)/(3)}=6$

Step-by-step explanation:

Given: 216 power of 1/3

We have to find an equivalent number to 216 power of 1/3

Consider 216 power of 1/3

Writing mathematically as, $(216)^{(1)/(3) }$

Also, 216 can be written as product of 6 three times that is 6× 6 × 6

Thus, $(216)^{(1)/(3)}=(6* 6* 6)^{(1)/(3)}$

Simplify, we get,

$(6* 6* 6)^{(1)/(3)}=(6^3)^{(1)/(3)}$

Apply property of exponents, we have,

$(a^n)^m=a^(nm)$

$(6^3)^{(1)/(3)}=6^{(3)/(3)}=6$

Thus, $(216)^{(1)/(3)}=6$

Option (b) is correct.

The cost of 8 muffins and 2 quarts of mil is $18. The cost of 3 muffins and 1 quart of milk is $7.50 hos much does 1 muffin and 1 quart of milk cost ?

Answers

Answer:

The cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .

Step-by-step explanation:

Let us assume that the cost of one muffins be x.

Let us assume that the cost of one 1 quarts of milk be y.

As given

The cost of 8 muffins and 2 quarts of mil is $18.

Than the equation becomes

8x + 2y = 18

As given

The cost of 3 muffins and 1 quart of milk is $7.50.

Than the equation becomes

3x + 1y = 7.50

Two equations are

8x + 2y = 18 and 3x + 1y = 7.50

Multiply 3x + 1y = 7.50 by 2 and subtracted from 8x + 2y = 18 .

Thus

8x - 6x + 2y - 2y = 18 - 15

2x = 3

$x = (3)/(2)$

x = 1.5

Put x = 1.5 in 3x + 1y = 7.50

3 × 1.5 + y = 7.50

y = 7.50 - 4.5

y = 3

Therefore the cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
