Mary has 200ml of hand sanitizer that is 15% alcohol. She mixes it with 200ml of a

11Alexandr11 [23.1K]

Answer:

(370-2x)ml

Step-by-step explanation:

We are given that

In first hand sanitizer

Total solution=200ml

Alcohol=15% of 200ml

Alcohol= $\frac{15}{100}\times 200=30ml$

In second hand sanitizer

Solution=200 ml

Alcohol=x% of 200 ml

Alcohol= $\frac{x}{100}\times 200=2x ml$

We have to find the water in the resulting mixture of hand sanitizers.

Total solution of two hand sanitizers=200+200=400ml

Total alcohol in two hand sanitizers=(30+2x)ml

Water in two hand sanitizers=400-(30+2x) ml

Water in two hand sanitizers=400-30-2x ml

Water in two hand sanitizers=(370-2x)ml

Hence, water in the resulting mixture of hand sanitizers=(370-2x)ml

To find the perimeter of a triangle, you would need first all three side lengths.

9.7m-6.8m = 2.9, 6.6m+6.5p=7.1, 2.2p-6.4= -4.2. once I added all the sides it was 5.8.
