The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (4,2).
vlabodo [156]

Answer:

-1/3

Step-by-step explanation:

Take the ratio of the corresponding sides to get the scale factor so for this equation let's use the hypotenuse.

The length of the hypotenuse of the larger triangle is 12 units and the smaller triangle's hypotenuse is 4 so 4/12 is the scale factor.

However 4/12  can be simplified down to 1/3.

Since the smaller triangle has been flipped upside down the scale factor is negative so the final answer is -1/3

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% sa
Vinvika [58]

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

C_{i}V_{i}=C_{f}V_{f}

Where:

  • C(i) is the initial concentration of the solution (80%)
  • C(f) is the final concentration of the solution (30%)
  • V(i) is the initial volume (150 ml)
  • V(f) is the final volume

Now, we just need to solve the equation for V(f).

V_{f}=\frac{C_{i}V_{i}}{C_{f}}

V_{f}=\frac{80*150}{30}

V_{f}=400\: ml

Therefore, we must add 400 ml of water.

I hope it helps you!
