12 out of 30 people chose their favourite colour as blue caculate the angle you would use for blue on a pie chart

GrogVix [38]

Answer:

The angle = 144 degrees.

Step-by-step explanation:

Look at it this way (it is a proportion question)

30 people would require a pie chart made of a full circle (360 degrees)

12 people would require x part of the pie chart.

30/360 = 12 / x Cross multiply

30x = 360 * 12 Simplify the right

30x = 4320 Divide by 30

30x/30 = 4320/20

x = 144 Answer

The distance from Neptune to Mars is 4.272\times 10^{9}4.272×10 9 kilometers. How long would it take a rocket, traveling at 4.8\

just olya [345]

The time taken is $8.9 * 10^4hrs

<h3>Distances</h3>

Given the following information:

Distance from Neptune to Mars = $4.272\times 10^{9}$
Time is taken = $4.8\times 10^{4}km/hr$

Get the time taken:

Time = Distance/Speed

Time = $\frac{4.272\times10^9}{4.8\times 10^4}$

Time = 0.89 * 10^5

Time = 8.9 * 10^4hrs

Hence the time taken is $8.9 * 10^4hrs

Don't spam...<br><br>Step by step explaination needed...

Anastasy [175]

Answer:

$\:$

Step-by-step explanation:

Given polynomial :

f(x) = 2x³–5x² + 5x

Let the number to be subtracted be n

(x is already in equation so, n is better)

since, 2x – 3 factor given

→

$f ( \frac{3}{2} ) = 0$

So,

$2x {}^{3} - 5x {}^{2} + 5 {x}^{2} - n$

$2x {}^{3} - 5x {}^{2} + 5x - n = 0 \\ \\ 2( \frac{3}{2} ) {}^{3} - 5( \frac{3}{2} ) {}^{2} + 5( \frac{3}{2} ) - n = 0 \\ \\ 2 \times \frac{27}{8} - 5 \times \frac{9}{4} + 5 \times \frac{3}{2} - n \: = 0 \\ \\ \frac{27}{4} - \frac{45}{4} + \frac{15}{2} - \frac{n}{1} = 0 \\ \\ 27 - 45 + 30 - 4n = 0 \\ \\ 12 - 4n \: = 0 \\ \\n = \frac{ - 12}{ - 4} \\ \\ n = > 3$
