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% ------------------ ?

The additional mass is calculated as;

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

Answer:
A) Steve = Ryan +18
B) Steve + Ryan = 144
A) Steve -Ryan = 18 then adding B

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

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
