A flowerpot weighs 5 newtons on Earth and 0.29 newtons on Pluto. A person weighs 115 newtons on Earth. Which proportion can you use to calculate this person’s weight on Pluto?
Two scales
A. 50.29=115w
B. 0.295=w115
C. 50.29=w115
D. either 50.29=115w or 0.295=w115
Can someone give full answers pls?
(5 N Earth)/(0.29 N Pluto) = (115 N Earth)/( x N Pluto)
To calculate the person's weight on Pluto, you can use the proportion:
D. either 50.29=115w or 0.295=w115
In this proportion, 'w' represents the person's weight on Pluto. By setting up and solving this proportion, you will be able to find the person's weight on Pluto.
To determine the proportion that can be used to calculate the person's weight on Pluto, we need to compare the weight on Earth to the weight on Pluto.
We know that the flowerpot weighs 5 newtons on Earth and 0.29 newtons on Pluto. We also know that the person weighs 115 newtons on Earth.
The weight on Earth and weight on Pluto can be compared using the following proportion: Earth weight / Pluto weight = Earth weight of person / Pluto weight of person.
Using this information, let's examine the options provided:
A. 50.29 = 115w
B. 0.295 = w115
C. 50.29 = w115
D. either 50.29 = 115w or 0.295 = w115
Option A is incorrect because it suggests a weight of 50.29 newtons on Earth, which is not given in the problem.
Option B is incorrect because it incorrectly states that 0.295 newtons is equal to w115, when it should be the other way around.
Option C is incorrect because it incorrectly states that 50.29 newtons is equal to w115, when it should be the other way around.
Option D is the correct answer because it recognizes that we have two possible proportions: 50.29 = 115w or 0.295 = w115. Either of these proportions can be used to calculate the person's weight on Pluto.
In conclusion, the correct option is D: either 50.29 = 115w or 0.295 = w115.
