Step-by-step explanation:
<u>Finding x</u>
- 2x - 28 = x/2
- 3/2x = 28
- 3x = 56
- x = 56/3 = 18.66666667
- The exact side length of the small square is <u>18.66666667 cm</u> and the exact side length of the big square is <u>37.3333334 cm</u>.
- The approximate side length of the small square is <u>18.7 cm</u> and the approximate side length of the big square is <u>37.3 cm</u>.
Answer:
2
Step-by-step explanation:
Copy 1 is a scaled copy of the original triangle. The scale factor is 2, because each side in Copy 1 is twice as long as the corresponding side in the original triangle. , , Copy 2 is a scaled copy of the original triangle.
Given:
Dimensions of a block are w = 5 cm, l = 8 cm, h = 12 cm.
To find:
The length of the space diagonal of a block.
Solution:
Length of the diagonal is
Putting the given values, we get
Round to the nearest tenth.
So, the length of the space diagonal of a block is 15.3 cm.
Therefore, the correct option is B.
