Theres 30 kilograms of 10% apple juice. How many kilograms of apples does it need to increase the current apple juice to 25%?

raketka [301]

The mass of the apple juice needed to increase the initial concentration to 25% is 45 kg

The given parameters;

Mass of the apple juice, m = 30 kg
current percentage, = 10%
final percent after increment = 25%

Let the mass added to increase the percentage to 30% = x

10% ----------------- 30 kg

25% ------------------ ?

$= \frac{25 \times 30}{10} \\\\= 75 \ kg$

The additional mass is calculated as;

$x+ 30 = 75\\\\x = 75 - 30\\\\x = 45 \ kg$

Thus, the mass of the apple juice needed to increase the initial concentration to 25% is 45 kg.

Identify all of the real fifth roots of 1024.

V125BC [204]

Answer:

Real fifth root of 1024 is 4.

Step-by-step explanation:

We have to find the value of real fifth root of 1024.

For this let fifth root of 1024 = x

Therefore $x^{5} = 1024 = 4^{5}$

Or $x^{5}=4^{5}$

Therefore x = 4

X= 4 is the right answer.

What is the value of x?

masya89 [10]

Answer:

Option D is correct.

Step-by-step explanation:

We can tell that

$4x + \frac{x}{2} + 2 + \frac{3x-4}{2} = 180$

Now, let's simplify.

=> $4x + 2 + \frac{4x-4}{2} = 180$

=> $4x + 2 + 2x-2 = 180$

=> $4x + 2x = 180$

=> $6x = 180$

=> $x = 30$

Therefore, Option D is correct.

Hoped this helped.
