Answer:
D
Step-by-step explanation:
We can test each pair making each ratio into its simplest form.
For A 2/3 is already in its simplest form and 9/15=3/5. they are not equivalent.
For B, 5/8 is already in its simplest form and 15/21=5/7. they are not equivalent.
For C, 3/12=1/4, and 6/18=1/3. They are not equivalent.
For D, 4/10=2/5, and 12/30=2/5. They are equivalent.
Answer: 6.4 feet
Step-by-step explanation:
Height of Atlas V rocket = 205 feet
Ratio of the model = 1:32 = 1/32
Model / Real = 1/32
Since Real height = 205, we put it into the equation and this will be:
Model / Real = 1/32
Model / 205 = 1/32
Model × 32 = 205 × 1
Model = 205/32
Model = 6.4 feet
The height of the model is 6.4 feet.
