How to solve 2/3:x::4.5:2 and 2/3%:1/5::50:x

solong [7]

A) x = 0.296

B) x= 15

Step-by-step explanation:

Step 1:

(2/3) : x :: 4.5 :2

By using expansion method,

(2/3) × 2 = 4.5 x

x= (2/3) × 2 / 4.5

x = 0.296

Step 2:

(2/3) : (1/5) :: 50 :x

By using expansion method,

(2/3) x = (1/5) × 50

x= (1/5) × 50 / (2/3)

x = 15

Which of the following is a sum of cubes?

saul85 [17]

Answer:

D) $x^3+8y^6$

Step-by-step explanation:

We have been given four choices.

A) $3x^3+8y^6$

B) $8x^3-27y^6$

C) $125x^6-9y^3$

D) $x^3+8y^6$

Now we need to find about which of the above choices is a sum of cubes.

Basically we need to check which one of the given choices can be represented in cubic form along with addition sign.

3 and 9 can't be written in cubic form unless we use radical numbers.

So the only choice left is D)

D) $x^3+8y^6$

$=x^3+2^3(y^2)^3$

$=x^3+(2y^2)^3$

which is clearly visible as sum of cubes.
