The flowerpot weighs 5 pounds on Earth and 0.29 pounds on Pluto. Which proportion could you use to calculate a 115-pound person’s weight on Pluto?
A. 5 over 0.29 = 115 over w
B. 0.29 over 5 = w over 115
C. 5 over 0.29 = w over 115
D. either A or B
d. 18!!!!
To calculate a 115-pound person's weight on Pluto, we need to set up a proportion using the given information.
Let w represent the weight of the person on Pluto.
Since the flowerpot weighs 5 pounds on Earth and 0.29 pounds on Pluto, we can set up the proportion:
(A) 5/0.29 = 115/w
Therefore, the proportion we could use to calculate a 115-pound person's weight on Pluto is A. 5 over 0.29 = 115 over w.
To calculate the weight of a 115-pound person on Pluto, we can use a proportion. A proportion is an equation that states that two ratios are equal.
Let's calculate the ratio of weight on Earth to weight on Pluto using the given information:
Weight on Earth / Weight on Pluto = 5 pounds / 0.29 pounds.
Now, we need to set up the proportion using this ratio. We can let "w" represent the weight of the person on Pluto.
Option A: 5 over 0.29 = 115 over w
This option sets up the proportion using the weight on Earth over the weight on Pluto ratio. This is the correct proportion to use.
Option B: 0.29 over 5 = w over 115
This option sets up the proportion using the weight on Pluto over the weight on Earth ratio. The order is reversed, making it an incorrect proportion.
Option C: 5 over 0.29 = w over 115
This option is the same as Option A, and it sets up the correct proportion.
Option D: either A or B
This option is correct because Option A is the correct proportion, and Option B is incorrect.
Therefore, the proportion we could use to calculate a 115-pound person's weight on Pluto is A. 5 over 0.29 = 115 over w.
