PLEASE HELP PLEASEEEE HELP

Mathematics
1 answer:
lianna [129]3 years ago
8 0

Answer:

Step-by-step explanation:

Rachel's \ share = \dfrac{2}{5}*600 \\\\\\

                       = 2 * 120

                       = £240

Remaining amount after giving Rachel's share = 600 - 240 = £360

Samina's \ share = \dfrac{1}{4}*360

                          = £90

Tom's share = 360 - 90  = £270

No, Tom's answer is wrong.

If they are sharing equally, 600 should be divide by 3.

600 ÷ 3 = £200 which less than £270.

What is the factored expression of 63x^2-3x-6
Murljashka [212]

Answer:

3(3x-1)(7x +2)

Step-by-step explanation:

63x^2-3x-6

Suppose a generic quadratic equation

ax^2 + bx + c

To factor this equation, I need to find its roots. Then we use the quadratic formula of:

\frac{-b + \sqrt{b^2-4ac}}{2a}

and

\frac{-b + \sqrt{b^2-4ac}}{2a}

So, for the equation 63x ^ 2-3x-6 we have:

\frac{3 + \sqrt{(-3)^2-4(63)(-6)}}{2(63)} = \frac{1}{3}

and

\frac{3 - \sqrt{(-3)^2-4(63)(-6)}}{2(63)} = \frac{-2}{7}

So:

(x-\frac{1}{3}) = 0\\\\(3x-1) = 0

and

(x - (-\frac{2}{7})) = 0\\\\(x+ \frac{2}{7}) = 0\\\\(7x +2) = 0

Finally the polynomial is:

(3x-1)(7x +2)

What is the percent error from 16 to 12
lubasha [3.4K]

Answer: 33.33...% percent error

Step-by-step explanation: To find the percent error from 16 to 12, we will be using the "percent error" equation.

difference = percent error x actual

To find the difference, subtract 12 from 16, which is 4.

4 = percent error x actual

The actual is 12 because, because a percent error from 16 to 12, means that the actual was 12 and the estimate was 16 because 16 was to "12"

4 = percent error x 12  (Solve for p, percent error)

4/12 = p

0.33... = p

Multiply 0.33.. by 100, to get the percent error.

0.33... x 100 = 33.33... or 33.33...%
