The length of the one side of the square room(a) = (4x - 3) ft

Step-by-step explanation:

Given,

The area of the room = 16X^2 - 24X  + 9 ft^2

Let 'a' be the length of the one side of the room.

To find, the length of the one side of the room(a) = ?

We know that,

The area of the square = a^{2}

Where, a is the side of the square

∴ a^{2} = 16X^2 - 24X  + 9

⇒ a^{2} = (4X)^2 - 2(4X)(3)  + 3^{2}

Using the algebraic identity,

(a-b)^{2} =a^{2} -2ab+b^{2}

⇒ a^{2} = (4x-3)^2

⇒ a = (4x - 3) ft

∴ The length of the one side of the square room(a) = (4x - 3) ft

What is the percentage of cacao in hot chocolate which is made of 480 grams of milk and 20 grams of cacao?
galina1969 [7]

Given that the hot chocolate is made of 480 grams of milk and 20 grams of cacao.

We need to determine the percentage of cacao in hot chocolate.

<u>The percentage of cacao:</u>

The total grams of hot chocolate can be determined by adding the total grams of milk and the total grams of cacao.

Total grams of hot chocolate = Grams of Milk + Grams of cacao

Total grams of hot chocolate = 480 + 20 = 500 grams.

Thus, the total grams of hot chocolate is 500 grams.

Now, we shall find the percentage of cacao.

The percentage of cacao is given by

\frac{100}{500}\times 20

Simplifying, the values, we get,

\frac{2000}{500}=4\%

Thus, the percentage of cacao is 4%

Answer:

Repeating

Terminating

Repeating

Repeating

Step-by-step explanation:

5 2/7 as improper fraction is 37/7 and it equals 5.28571428571 which makes it repeating because the numbers don't stop.

7/16 is equal to 0.4375 making it terminate because the numbers stop.

14 5/9 as an improper fraction is 131/9 and 131/9 is 14.5555555556 and that is a never ending pattern so it is repeating.

3/22 is equal to 0.13636363636 it is repeating because the numbers never stop.
