Mathematics
1 answer:
slega [8]3 years ago
4 0

Answer:

C. 5

Step-by-step explanation:

Triangle BED is enlarged by scale factor 4.

(25-x)/4 = x

Multiply both sides by 4.

25-x = 4x

Add x on both sides.

25 = 5x

Divide both sides by 5.

5 = x

What is a speed of 55 mph equivalent to in units of m/s? ( 1 mile = 1609 m, 1 hour = 3600 s)
koban [17]

9514 1404 393

Answer:

  about 24.58 m/s

Step-by-step explanation:

Multiply by conversion factors that change the units, but not the value.

  (55 mi/h) × (1609 m/mi) × (1 h)/(3600 s) = (55×1609/3600) m/s

  = 88495/3600 m/s ≈ 24.58 m/s

_____

<em>Additional comment</em>

The exact conversion uses 1609.344 meters per mile, so gives exactly 24.5872 m/s.
