0.0323 as a fraction

svetoff [14.1K]

Answer:

» $\frac{323}{10000}$

Step-by-step explanation:

To convert the decimal 0.0323 to a fraction,

just follow these steps:

Step 1: Write down the number as a fraction of one:

$0.0323 = \frac{0.0323}{1}$

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 4 numbers after the decimal point,

So, we multiply both numerator and denominator by 10000.

Therefore ;

→ $\frac{0.0323}{1} = \frac{(0.0323 \times 10000)}{(1 \times 10000)} \\ \\→ \frac{323}{10000}$

Acute △ABC with angles α, β, and γ is inscribed in a circle. Tangents to the circle at points A, B, and C intersect in points M,

SOVA2 [1]

Answer:

The measures of angles of triangle MNP are

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the measure of arcs AB, BC and AC

we know that

The inscribed angle is half that of the arc it comprises.

$\gamma=\frac{1}{2}[arc\ AB] ----> arc\ AB=2\gamma\\\alpha=\frac{1}{2}[arc\ BC] ----> arc\ BC=2\alpha\\\beta=\frac{1}{2}[arc\ AC] ----> arc\ AC=2\beta$

step 2

Find the measure of angle M

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

$M=\frac{1}{2}[arc\ AB+arc\ BC-arc\ AC]$

substitute

$M=\frac{1}{2}[2\gamma+2\alpha-2\beta]\\M=[\gamma+\alpha-\beta]$

step 3

Find the measure of angle N

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

$N=\frac{1}{2}[arc\ AC+arc\ BC-arc\ AB]$

substitute

$N=\frac{1}{2}[2\beta+2\alpha-2\gamma]\\N=[\beta+\alpha-\gamma]$

step 4

Find the measure of angle P

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

$P=\frac{1}{2}[arc\ AC+arc\ AB-arc\ BC]$

substitute

$P=\frac{1}{2}[2\beta+2\gamma-2\alpha]\\P=[\beta+\gamma-\alpha]$

Which sequence is geometric

Vitek1552 [10]

If a, b, c, d is geometric sequence, then

$\dfrac{b}{a}=\dfrac{c}{b}=\dfrac{d}{c}=const.$

A. 5; 15; 25; 35

$\dfrac{15}{5}=3;\ \dfrac{25}{15}=\dfrac{5}{3}-NOT$

B. 5; 10; 20; 40

$\dfrac{10}{5}=2;\ \dfrac{20}{10}=2;\ \dfrac{40}{20}=2-YES$

C. 6; 12; 18; 24

$\dfrac{12}{6}=2;\ \dfrac{18}{12}=\dfrac{3}{2}-NOT$

D. 7; 14; 21; 28

$\dfrac{14}{7}=2;\ \dfrac{21}{14}=\dfrac{3}{2}-NOT$

Answer: The sequence B. 5; 10; 20; 40 is geometric.
