What is the value of h in the figure below? In this diagram, ABAD - ACBD.
andreev551 [17]

Answer:

h =12

Step-by-step explanation:

In\: \triangle ABC, \: \angle ABC = 90\degree \: \&\:\\ BD\perp AC

Therefore, by geometric mean property:

BD = \sqrt {AD\times CD} \\h = \sqrt {(AC-CD) \times CD} \\h = \sqrt {(25-16) \times 16} \\h = \sqrt {9 \times 16} \\h = \sqrt {144} \\\huge \red {\boxed {h = 12}} \\

How do I do this puzzle
irga5000 [103]
It's just saying that you need to find the volume and surface area and then write them in the designated area, which will be on the side or the bottom. 

After doing this for all of them, you have to find two matching numbers and put them together on the same side. 

For example:
When you got 722, you can just find another square that might say 722 on square area or volume, then just put the numbers together on the same side.

I don't know if this helped but I hope it did!

6,2 x 10^2 = 0 x t + 1/2 x (-9/8) t^2 + 2582,91
Diano4ka-milaya [45]

Answer:

≠

Step-by-step explanation:

  • 6,2 × 10² = 0 × t + ½ × (-9/8) × t² + 2582,91

  • 6,2 × 100 = 0 + ½ × (-9/8) × t × t + 2582,91

  • 620 = ½ × (-9/8) × t × t + 2582,91

  • 620 = (-9/16) × t × t + 2582,91

  • 620 = (-9/16 t²) + 2582,91

  • 620 ≠ 1.032.939/400 t²

  • 6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91

Conclusion:

6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91
