Answer:

To calculate the actual yield of iron in moles, we need to use the molar mass of iron (Fe) and the given mass of iron produced.

The molar mass of iron (Fe) is approximately 55.845 g/mol.

Given:

Amount of Fe2O3 = 0.288 mol

Mass of Fe produced = 18.1 g

To find the moles of Fe produced, we can use the molar mass of Fe:

moles of Fe = mass of Fe / molar mass of Fe

moles of Fe = 18.1 g / 55.845 g/mol

moles of Fe ≈ 0.324 mol

Therefore, the actual yield of iron in moles is approximately 0.324 mol.

The given dimensions of the rectangular swimming pool are =

Length = 20 feet

Width = 12 feet

Height upto which the water should be filled up = 5 feet

So, the total volume of water needed to fill the pool will be =

cubic feet

The water is pumped at a speed of = 30 cubic feet per minute.

So, to fill 1200 cubic feet, the time taken will be =

Hence, it will take 40 minutes to fill the pool.

Answer:

$180,000.

Step-by-step explanation:

We have been given that a student attends a four-year college with tuition costs of $20,000 per year, room and board costs of $5,000 per year, and books/entertainment costs of $1,000 per year. If the student did not go to college, she would work at a job that pays $25,000 per year but still face the same room and board and entertainment expenses.

We know that opportunity cost is the profit lost, when one alternative is selected over another.

Opportunity cost of attending college for 4 years would be amount lost from job in 4 years plus amount spent on studies because the student lost $25,000 for four years for not doing the job and spent $20,000 for 4 years on studies.

Therefore, the opportunity cost of attending college for this student for four years is $180,000.

Final answer:

The opportunity cost of attending college for four years is $100,000.

Explanation:

The opportunity cost of attending college for four years is the value of the best alternative that the student foregoes by choosing to attend college. In this case, the student could have worked and earned $25,000 per year instead of going to college. So, the opportunity cost for four years would be $25,000 * 4 = $100,000.

Answer:

Answer is option b

17 feet.

Step-by-step explanation:

Given that A tree casts a 25 foot shadow. At the same time of day, a 6 foot man standing near the tree casts a 9 foot shadow.

for man actual height = 6 foot

Shadow = 9 foot

At a particular time, the height/shadow ratio would be constant

Hence 6/9 =x/25

Or x = 25(6)/9

x=16.67feet

Rounding off x=17 feet
