Answer:

5 months

ROI = 3.75 %

Step-by-step explanation:

Since,

The simple interest formula,

Where,

P = Principal amount,

r = rate per period ( in decimal )

t = number of periods,

Here, P = 800, r = 9% = 0.09,

If A is the future amount,

We have, A = 830

I = A - P = 830 - 800 = 30

By substituting the values in the above formula,

Hence, it will take 5 months.  ( 1 year = 12 months )

Now,

Iin expanded form, 5.724 is: 5 + 7/10 + 2/100 + 4/1000

How to write in expanded form

The number 5.724 can be written in expanded form as:

• The digit "5" represents the whole number part.
• The digit "7" after the decimal point represents 7 tenths, or 7/10.
• The digit "2" after that represents 2 hundredths, or 2/100.
• The digit "4" at the end represents 4 thousandths, or 4/1000.

5 + 7 * (1/10) + 2 * (1/100) + 4 * (1/1000)

So, in expanded form, 5.724 is:

5 + 7/10 + 2/100 + 4/1000

Answer:

The way I would write it is: 700,000 + 20,000 + 4,000= 724,000

Step-by-step explanation: How I got that answer is that is how you write in expandad form.

Answer:

6π ft

Step-by-step explanation:

PA=3ft

Then just double it to get your answer.

Answer:

It is only (5,24).

Step-by-step explanation:

You are correct.

Sometimes, check all options means there could be just one option.

Answer:

  (–ꝏ, 0) U (0, 5)

Step-by-step explanation:

The relation can be written as ...

  x³ < 5x²

  x³ -5x² < 0

  x²(x -5) < 0

This is not true for x = 0. It is true for x < 5, otherwise. Then the solution set is ...

  x ∈ {(–ꝏ, 0) U (0, 5)}

The cube of any number from the set (-∞, 0) ∪ (0, 5) is less than five times the square of the number. So, the third option is correct.

Mathematically, a set is a collection of distinct, well-defined objects forming a group.

Let the number be x.

Then, according to the question:

x³ > 5x²

x³ - 5x² > 0

x²(x - 5) > 0

x² > 0 or x - 5 > 0

x > 0 or x > 5

This implies that

x ∈ (-∞, 0) ∪ (0, 5)

Hence, the correct answer is the third option, (-∞, 0) ∪ (0, 5).
