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:
longest side=3.6
let ratio 3:5:6:9be 3x,5x,6xand9x
perimeter= sum of all side
9.2=3x+5x+6x+9x
9.2=23x
x=9.2÷23
x=0.4
9x=9×0.4=3.6
6x=6×0.4=2.4
5x=5×0.4=2
3x=3×0.4=1.2
The amount of tax you would have to pay would be $3.25
We have to divide 3 1/2 by 1 3/4:
3 1/2 : 1 3/4 = 7/2 : 7/4 = 7/2 * 4/7 = 2
Answer:
A ) 2 bricks are in the stack.
Hi!
So f(x) = 2x + 1
Since f(2), that means x = 2
f(2) = 5
Let's do a few more (the ones I don't do, you have to figure out!)
f(t + 1)...
f(t + 1) = 2(t + 1) + 1
f(t + 1) = 2t + 2 + 1
f(t + 1) = 2t + 3
g[f(m+2)]...
g[f(m+2)] = 2m + 5
Hope this helps! DM me if you need to know the rest. :)
