What is this simplified using order of operations 100-20[18-2(5+2)]

Answer:

2/5 and 20

Step-by-step explanation:

1/4 = 5/20

2/5 = 8/20

LCD = 20

Answer:

14 cm

Step-by-step explanation:

1. First, we need to find the total volume of Tank A. Tank A is a rectangular prism, and the volume of a rectangular prism is given by the formula length x width x height. In this case, it's...

50 cm x 70 cm x 70 cm = 245,000 cubic cm

2. Tank A was 2/7 full, so we need to find out how much water was in Tank A.

To find this, we multiply the total volume by the fraction that's full:

245,000 cm³ * 2/7 = 70,000 cm³.

3. This 70,000 cm³ of water was then poured into Tank B. We want to find out how high the water is in Tank B, so we need to divide the volume of the water by the base area of Tank B.

4. The base area of Tank B is given as 5000 cm². So, the height of the water in Tank B is 70,000 cm³ / 5000 cm² = 14 cm.

So, the height of the water in Tank B is 14 cm.

Hope this helps! :)
