2. Some fractions could be different in denominator and numerator so you'll have to make all denominators the same in order to order them. It'll make it easier because the numerator will show which numbers are greater than the other. For example, 1/2 and 3/4, u could convert both to equivalent fractions. Make 1/2 into 2/4 and 3/4 stays the same, 3/4 is greater than 2/4 so it goes first.

3. 2/3, 7/12, 4/9, 1/2, 3/8, 5/24.
It's in this order because their equivalent fractions are,
27/72, 48/72, 36/72, 42/72, 36/72, 15/72.( that's the order they're in in the question)

if an amount of $5,000 is deposited into a savings account at an annual interest rate of 5%, compounded monthly, what is the val

Ugo [173]

Answer:

$8,240

Step-by-step explanation:

We are given that,

Principle amount in the savings account, P = $5,000.

Rate of interest, r = 5% = 0.05

Time period, t = 10

Also, the interest is compounded monthly, n = 12

As, we now that the value of the investment is given by $P(1+\frac{r}{n})^{nt}$

Thus, we have,

Investment Value = $5000(1+\frac{0.05}{12})^{12\times 10}$

i.e. Investment Value = $5000(1+\frac{0.05}{12})^{12\times 10}$

i.e. Investment Value = $5000(1+0.00417)^{120}$

i.e. Investment Value = $5000\times 1.648$

i.e. Investment Value = $8,240

Hence, the investment amount after 10 years is $8,240.

A bike shop rents bikes for $4.50 per hour, plus a $7.50 insurance charge. For how many hours can Peter rent a bike if he has $3

Mandarinka [93]

Answer:

With $30, Peter can afford 5 hours

Step-by-step explanation:

Given

Insurance Charge = $7.5

Charges = $4.5 per hour

Required

Determine the number of hours $30 can afford

First, we need to determine the equation.

<em>Total Charges = Charges per hour + Insurance Charge</em>

Substitute values for Charges per hour and Insurance Charge

Total Charges = 4.5 per hour + 7.5

Let the number of hours be n;

So,

Total Charges = 4.5n + 7.5

To calculate Peter's; substitute 30 for total charges

$30 = 4.5n + 7.5$

Subtract 7.5 from both sides

$4.5n = 30 - 7.5$

$4.5n = 22.5$

Divide both sides by 4.5

$n = \frac{22.5}{4.5}$

$n = 5$

Hence;

<em>With $30, Peter can afford 5 hours</em>
