Answer:

The answer to your question is: 4 7/12 hours  

Step-by-step explanation:

Data

1 5/6 mowing the lawn

3/4 trimming the hedge

2 2/3 weeding the garden

Process

Convert mixed fractions to improper fractions

          1 5/6 = (6 + 5 ) / 6 = 11 / 6

           2 2/3 = (6 + 2) / 3 = 8 / 3

Sum the fractions

         11/6 + 8/3 + 3/4 =  ( 22 + 24 + 9) / 12

                                   = 55 / 12          

                                  = 4 7/12 hours

Answer: 53/5, 101/20

Step-by-step explanation:

10.6 is =  106/10. Then divide both numerator and denominator by 2. Then it equals 53/5.

5.05 = 505/100. Then divide both numerator and denominator by 5. This will equal 101/20.

Which number line correctly shows 4. 5 + 2. 5? A number line going from 0 to 4. 5 in increments of 0. 5. An arrow goes from 0 to
sesenic [268]

So none of the options is actually correct from the given operation of:

4.5 + 2.5

This actually would be represented with a line that goes from 0 to 4.5, and then from 4.5 to 7.

The number line should start at 0 and then move to the first number (because of the commutative property of the sum, it can move to any one of the two numbers).

Once there, it moves accordingly to the other number.

So it moves first from 0 to 4.5, then the second number is 2.5, then it moves another 2.5 units to the right until the:

4.5 + 2.5 = 7

Concluding, <u><em>it moves from 0 to 4.5, then from 4.5 to 7.</em></u>

Notice that none of the options represent this, this may be because the sign of one of the two numbers is incorrect or something like that.

For example, if we had the operation:

4.5 - 2.5

Then the line starts at 0 and then goes to 4.5, then moves left 2.5 units to 4.5 - 2.5 = 2

In this case, the correct option should be:

<u><em>"An arrow goes from 0 to 4. 5 and then backwards from 4. 5 to 2."</em></u>

You just purchased two coins at a price of $670 each. Because one of the coins is more collectible, you believe that its value w
DerKrebs [107]

Answer:

The value of first coin will be $151.51 more than second coin in 15 years.

Step-by-step explanation:

You have just purchased two coins at a price of $670 each.

You believe that first coin's value will increase at a rate of 7.1% and second coin's value 6.5% per year.

We have to calculate the first coin's value after 15 years by using the formula

A=P(1+\frac{r}{100})^{n}

Where A = Future value

           P = Present value

           r = rate of interest

           n = time in years

Now we put the values

A=670(1+\frac{7.1}{100})^{15}

A=670(1+0.071)^{15}

A=670(1.071)^{15}

A = (670)(2.797964)

A = 1874.635622 ≈ $1874.64

Now we will calculate the value of second coin.

A=670(1+\frac{6.5}{100})^{15}

A=670(1+0.6.5)^{15}

A=670(1.065)^{15}

A = 670 × 2.571841

A = $1723.13

The difference of the value after 15 years = 1874.64 - 1723.13 = $151.51

The value of first coin will be $151.51 more than second coin in 15 years.
