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;

  • <em>Mass of the apple juice, m = 30 kg</em>
  • <em>current percentage, = 10%</em>
  • <em>final percent after increment = 25%</em>

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.

Find S (2x² -4/x² )dx<br><br>​
SOVA2 [1]

Answer:

if those functions under the radical are multiplied together they can be expanded as:

I=((x1+x2)^2 - 1)*(1-(x1-x2)^2)/8

let u=x1+x2 and v=x1-x2

I = (u ^ 2–1) * (1-v ^ 2)

du = dx1 + dx2; dv = dx1-dx2;

dx1 * dx2 = (du-dx2) * (dx1-dv)

or-or-or ...

int(I)*dx1*dx2=5/2

Plz I need help this is due at 7:10
solmaris [256]

Answer:

8units²

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the opposite sides

h is the height

Take a square as 1 unit

a = 1 unit

b = 3 units

height h = 4 units

Substitute

A = 1/2(1+3)*4

A = 1/2 * 4 * 4

A = 16/2

A = 8units²

Hence the area of the trapezoid is 8units²
