Tim has 5 times as many stamps as rylis.. They have 1038 stamps in all.. How many more stamps does Tim have than rylis?
lianna [129]
Since Tim's stamps are 5 times as many, set up the equation:

1038=5s+1s
1038/6=173=s

Ryli has 173 stamps, and Tim has 865.
Subtract 173 from 865 and you get 692 stamps more.

What are the roots of 3x2 + 10 = 4x?
sveticcg [70]

Answer:

Option C is correct.

roots of the given equation , x =\frac{2\pm i\sqrt{26}}{3}

Step-by-step explanation:

Given the equation: 3x^2+10 = 4x

We can write this equation as:

3x^2-4x + 10 =0

A quadratic equation is in the form of ax^2+bx+c =0      ......[1] where a,b ,c are the coefficient and x is the variable,

the solution of the equation is given by;

x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}

On comparing given equation with equation [1] we get;

a = 3 , b = -4 and c =10

So, the solution of the given equation is given by;

x = \frac{-(-4)\pm\sqrt{(-4)^2-4(3)(10)}}{2(3)}

or

x =  \frac{4\pm\sqrt{(16-120}}{6} = \frac{4\pm\sqrt{(-104)}}{6} = \frac{4\pm\sqrt{(-4 \times 26)}}{6}

or

x =\frac{4\pm2 \sqrt{(-26)}}{6} = \frac{4\pm2 i\sqrt{26}}{6}    [∴\sqrt{-1} = i

Simplify:

x =\frac{2\pm i\sqrt{26}}{3}

therefore, the roots of the given equation are; x =\frac{2\pm i\sqrt{26}}{3}

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
