The scale factor of dilation is $\LARGE \frac{1}{4}$ .

<h3>What is scale factor?</h3>

When describing an enlargement you must state by how much the shape has been enlarged or reduced.

Area of triangle B = $\frac{1}{2} * b *h$

= 0.5 x 2 x 3

= 3 units

Area of triangle A = $\frac{1}{2} * b *h$

= 0.5 x 4 x 6

= 12 units

Scale factor = $\frac{Area of \; triangle B}{Area of\; triangle A}$

= $\frac{3}{12}$

= $\frac{1}{4}$

Hence, the scale factor of dilation is $\LARGE \frac{1}{4}$ .

How much water should we add to 20 kg of seawater to change its concentration from 3% to 2%?

zhannawk [14.2K]

Answer:

10 kg

Step-by-step explanation:

In 3% concentration of 20 kg of seawater, there will be $\frac{20 \times 3}{100} = 0.6$ kg of salt.

So, if it is a 2% solution of seawater,

Then 2 kg salt will be there in 100 kg solution.

So, 0.6 kg salt will be there in $\frac{100 \times 0.6}{2}= 30$ kg of solution.

So, to make a solution from 3% to 2% we have to add (30 - 20) = 10 kg of water with a 20 kg solution. (Answer)
