How many repeating digits are in the smallest group of repeating digits in the decimal equivalent of the fraction shown?
Anna11 [10]

If <em>x</em> = 745/999, then

999<em>x</em> = 745

1000<em>x</em> - <em>x</em> = 745

This equation tells us that the fractional part of 1000<em>x</em> and <em>x</em> cancel upon subtracting. This means the block of repeating digits must be 3 digits long.

To verify this, suppose we write <em>x</em> = 0.<em>yyy</em>… , where <em>y</em> consists of 3 digits. Then

1000<em>x</em> = <em>y</em>.<em>yyy</em>…

1000<em>x</em> - <em>x</em> = <em>y</em>.<em>yyy</em>… - 0.<em>yyy</em>…

999<em>x</em> = <em>y</em>

<em>x</em> = <em>y</em>/999

which means <em>y</em> = 745.

A hexagonal prism has a base with an area of 15 square inches and the volume is 105 cubic inches.
Lina20 [59]

Answer:

The height is 7 inches

Step-by-step explanation:

Given

Base\ Area = 15in^2

Volume = 105in^3

Required

Determine the height [missing from the question]

The volume of a hexagonal prism is:

Volume =  Base\ Area * Height

Make Height the subject

Height = \frac{Volume}{Base\ Area}

Height = \frac{105in^3}{15in^2}

Height = \frac{105in}{15}

Height = 7in

Zielflug [23.3K]

9514 1404 393

Answer:

  3.77

Step-by-step explanation:

For daily compounding, the balance is ...

  A = P(1 +r/365)^n . . . . principal P invested at annual rate r for n days

  A = 1000(1 +0.055/365)^25 ≈ 1003.77

Of this amount, 1000 is the original principal. The difference is the interest.

The interest earned is 3.77.

Rewrite f(x) = -(x + 3)2 - 1 from vertex form to standard form. (2 points)
Mandarinka [93]

Answer:

f(x) = -x^2 - 6x - 10

Step-by-step explanation:

Please write the original equation as  f(x) = -(x + 3)2 - 1, as "(x + 3)2 is meaningless.  We want:

f(x) = -(x + 3)^2 - 1, where " ^ " denotes exponentiation.

Expanding this, we get:

f(x) = -(x^2 + 6x + 9) - 1, or

f(x) = -x^2 - 6x - 9 - 1, or:

f(x) = -x^2 - 6x - 10          This matches the first answer choice.
