Answer: $0.8$

Step-by-step explanation:

By definition, to express a fraction in decimal form, you need to divide the numerator by the denominator.

In this case, given the following fraction:

$\frac{4}{5}$

You can observe that the numerator is 4 and the denominator is 5. Therefore, you need to divide 4 by 5 in order to express it in decimal form.

Then, this is:

$\frac{4}{5}=0.8$

<h3><u>Fraction to Decimal:</u></h3>

Divide the numerator (upper number) by the denominator (bottom number) on your calculator. Whatever number you get would be your decimal.

<h3><u>Decimal to Percent:</u></h3>

Take your decimal and use your calculator to multiply it by 100. Whatever number you get would be your percent. However, since it is a percent, you need to include the percentage unit.

<h3><u>Demonstration:</u></h3>

1/4 = 0.25

0.25 * 100(%) = 25%

Write the following in standard form: 6x^3-8x^4+5x+12x^2-9

kondaur [170]

Answer:

$-8x^4 + 6x^3 + 12x^2 + 5x -9$

Step-by-step explanation:

To write a polynomial in standard form, list its terms from highest to lowest degree. The degree of a term is represented by its exponents. Thus, rearrange the terms so that the terms with the highest exponents are first and the ones with the lowest are last.

$6x^3-8x^4+5x+12x^2-9\\-8x^4 + 6x^3 + 12x^2 + 5x -9$

Thus, $-8x^4 + 6x^3 + 12x^2 + 5x -9$ is the answer.

Answer:

4. 4 tablets

5. no, 5 tablets

6. 19320 mg, 19.32 g

Step-by-step explanation:

4. 500 ÷ 125 = 4 tablets

5. a) no

b) 150 ÷ 30 = 5

you should be given 5 tablets

6. There are approximately 2.205 lbs in one kg.

Therefore, 142 lb = 142 ÷ 2.205 = 64.4 kg

300mg/kg/day

Therefore, number of mg per day = 300 x 64.4 = 19320 mg

b) As 1000mg = g

19320 ÷ 1000 = 19.32 g (nearest hundredth)

A rectangle has vertices (8, 6), (4, 6), (8, −4), and (4, −4). What are the coordinates after dilating from the origin by a scal

Mila [183]

Answer:

The coordinates of A(8, 6), B(4, 6), C(8, −4), and D(4, −4) after dilating from the origin by a scale factor of 1.5 will be: A'(12, 9), B'(6, 9), C'(12, -6), D'(6, -6)

Step-by-step explanation:

When we dilate a figure from the origin by a scale factor of 1.5, it means we will multiply the coordinates of the original figure with 1.5.

As the scale factor is 1.5 which is > 1, therefore the image will be enlarged.

As the rectangle has vertices A(8, 6), B(4, 6), C(8, −4), and D(4, −4)

The coordinates after dilating from the origin by a scale factor of 1.5 will be:

P(x, y) → P' (1.5x, 1.5y)

A(8, 6) → A'(8×1.5, 6×1.5) = A'(12, 9)

B(4, 6) → B'(4×1.5, 6×1.5) = B'(6, 9)

C(8, -4) → C'(8×1.5, -4×1.5) = C'(12, -6)

D(4, -4) → D'(4×1.5, -4×1.5) = D'(6, -6)

Therefore, the coordinates of A(8, 6), B(4, 6), C(8, −4), and D(4, −4) after dilating from the origin by a scale factor of 1.5 will be: A'(12, 9), B'(6, 9), C'(12, -6), D'(6, -6)
