1.6/n = 1.2/20<br> What's the correct answer?

natita [175]

Answer:

n = 26 2/3

Step-by-step explanation:

Step 1: Cross-multiply.

$(1.2) * (n) + 1.6*20$
$1.2n =32$

Step 2: Divide both sides by 1.2

$1.2n/1.2 = 32/1.2$
$n = 26\frac{2}{3}$

Therefore, the answer is n = 26 2/3.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

The area for one side is S^2 where S is the length of one side.

The area for one side = 1/2^2 = 1/4 square foot.

A cube has 6 sides. Total surface are = 1/4 x 6 = 1 1/2 square feet.

Volume of a cube is S^3

1/4^3 = 1/64 cubic foot.
