The pie chart shows the flavours of ice cream sold by a shop in one
Vadim26 [7]

Given:

The pie chart shows the flavours of ice cream sold by a shop in one  day.

There were a total of 270 ice creams sold.

To find:

The number of vanilla flavoured ice creams sold.

Solution:

We know that the complete central angle is 360 degrees.

From the given pie chart, it is clear that the central angle of the vanilla flavoured ice creams sold is 60 degrees.

Total ice creams sold = 270

Now, the number of vanilla flavoured ice creams sold is

n=\dfrac{\text{Central angle of vanilla}}{\text{Complete central angle}}\times \text{Total ice creams sold}

n=\dfrac{60^\circ}}{360^\circ}}\times 270

n=\dfrac{1}{6}\times 270

n=45

Therefore, the number of vanilla flavoured ice creams sold is 45.

Write 8/4 as a mixed number. how did you come to your answer
Sergeeva-Olga [200]
To write in the mixed fraction you have to simply divide 8 and 4. 
To right in the mixed number we need to know numerator, denominator and divisor. 
So in your problem our divisor is 4, 
so now lets divide it 
\frac{8}{4}
=  \frac{2}{1}

So, now we have to write it as mixed number..
mixed number  will be 
2  \frac{0}{8}

Hope this helped you.. :)

Use the remainder therom to find the remainder when x^4-3x^2-9x+4 is divided by x-3
KatRina [158]
If we can write the given polynomial as

\underbrace{p(x)}_{\text{given}}=q(x)(x-3)+r(x)

that is, write p(x) as the product of two factors plus some remainder term, then we can simply plug in x=3 to determine the remainder term because that would force the q(x) term to vanish.

p(x)=x^4-3x^2-9x+4\implies p(3)=31

so the remainder upon dividing p(x) by x-3 is 31.
