Answer:

The total length of the molding is 21 feet and 6 inches

Step-by-step explanation:

* Lets explain how to solve the problem

- The length of the two pieces are 8 feet 7 inches and 12 feet 11 inches

- Each foot has 12 inches

- Lets change the lengths of the two pieces to inch

# First piece 8 feet 7 inches

∵ 1 foot = 12 inches

∴ 8 feet 7 inches = 8 × 12 + 7

∴ 8 feet 7 inches = 96 + 7

∴ 8 feet 7 inches = 103 inches

# Second piece 12 feet 11 inches

∵ 1 foot = 12 inches

∴ 8 feet 7 inches = 12 × 12 + 11

∴ 8 feet 7 inches = 144 + 11

∴ 8 feet 7 inches = 155 inches

- To find the total length add the two answers

∴ The total length of the molding = 103 + 155 = 258 inches

- Divide the answer by 12 to change it to feet

∵ 258 ÷ 12 = 21.5 feet

- To change it to feet and inch multiply 0.5 feet by 12

∵ 0.5 × 12 = 6 inches

∴ The total length of the molding is 21 feet and 6 inches

Answer:

  $20.01

Step-by-step explanation:

In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...

  (1.00002^17)(1.00004^1) = 1.00038006801

Then the account balance is ...

  $20 × 1.00038006801 ≈ $20.01

_____

<em>Additional comment</em>

The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) <em>only if there is no rounding in intervening years</em>.

What step do I do next ?
Svetach [21]
When it comes to dividing decimals, bear in mind that, first off you'd want to do away with the decimal point.

now, "you add as many zeros to the other term, as it has decimals", what the heck does that mean?

for example 2.135 ÷ 5

notice, the 2.135 has three decimals, namely three numbers to the right of the decimal point.

since 2.135 has three decimals, then what we do, we add three zeros to 5, AND do away with the decimal point, thus our division is really

2135 ÷ 5000, which is 0.427

now, if we had 2.135 ÷ 5.79

what we do is, since 2.135 has three decimals, we add three zeros to 5.79, and since 5.79 has two decimals, we add two zeros to 2.135, then our division is really

213500 ÷ 579000  <-- notice, no dot on both

which is about 0.3687392

anyhow, that said, check the picture below
