If 60 marks is 40%, how much is full marks (Show your working out)?

2 answers:

8 0

' 40% ' means 0.4 .

You said that   60       = 0.4 x Full

Divide each side by 0.4 :    60 / 0.4 = 1 x Full

   Full = 150 .

60/X = 40/100
60•100=40X
6000=40X
6000/40=X
150=X

60 is 40% of 150

Answer:

If it is $\sqrt{96} \sqrt{96}$ then it is the solution $\sqrt{96} \sqrt{96} = 96$ because the square root of an expression multiplied by itself gives that expression.

Write 9− 16x⁴ as the product of two factors.

Marysya12 [62]

Answer:

The two factors will be $=(3+4x^2)\ and\ (3-4x^2)$

Step-by-step explanation:

We have given the equation $9-16x^4$

We know the algebraic equation $a^2-b^2=(a+b)(a-b)$

As $9-16x^4$ can be written as $3^2-(4x^2)^2$ , as square of 3 is 9 and square of $4x^2$ is $16x^4$

So $9-16x^4=3^2-(4x^2)^=(3+4x^2)(3-4x^2)$

So the two factors will be $=(3+4x^2)\ and\ (3-4x^2)$
