Answer:

The answer is 8.5

Step-by-step explanation:

The nearest tenth of a number is the first decimal. As can be seen, 8.54 has two decimals, so we must round the first one. If the second decimal was 5 or bigger than 5, then the first decimal would be increased by 1, and 8.54 would be rounded to 8.6. However, the second decimal is smaller than 4, so the first decimal remains the same, and 8.54 is rounded to 8.5.

Hope this help

Have a nice day!!!!

What is the longest line segment that can be drawn in a right rectangular prism that is 15 cm​ long, 11 cm​ wide, and 10 cm​ tal
sammy [17]

Answer:

  √446 ≈ 21.12 cm

Step-by-step explanation:

The longest dimension of a rectangular prism is the length of the space diagonal from one corner to the opposite corner through the center of the prism. The Pythagorean theorm tells you the square of its length is the sum of the squares of the dimensions of the prism:

  d² = (15 cm)² +(11 cm)² +(10 cm)² = (225 +121 +100) cm² = 446 cm²

  d = √446 cm ≈ 21.12 cm

The longest line segment that can be drawn in a right rectangular prism is about 21.12 cm.

_____

<em>Additional comment</em>

The square of the face diagonal is the sum of the squares of the dimensions of that face. The square of the space diagonal will be the sum of that square and the square of the remaining prism dimenaion, hence the sum of squares of all three prism dimensions.
