frosja888 [35]

Answer:

  • 28 m
  • 15 m
  • 24.8 m
  • 1.0 m

Step-by-step explanation:

The given statement is the scale factor:

  \dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}

This can be rearranged to the formula ...

  \text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}

Filling in the given scale distances, you find the actual distances to be ...

  \textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\

Elina [12.6K]

Answer:

The mentioned flowers can be arranged in 48 different ways.

Step-by-step explanation:

To determine in how many ways the mentioned flowers can be arranged (3 tulips, 2 yellow roses, and 8 lilies), all the variables must be multiplied together, and the result will be the number of possibilities for organizing them. Thus, the resolution of this question is the following:

3 x 2 x 8 = X

6 x 8 = X

48 = X

Therefore, the mentioned flowers can be arranged in 48 different ways.
