Question

Spiral Review (5.NBT .2, 5.NBT .3b, 5.NBT .7, 5.NF.3) 3. An object that weighs 1 pound on Earth weighs 1.19 pounds on Neptune. Suppose a dog weighs 9 pounds on Earth. How much would the same dog weigh on Neptune?

Answer 1

To calculate the weight of a dog on Neptune, multiply the Earth weight (9 pounds) by the ratio of Neptune weight to Earth weight (1.19). The dog would weigh 10.71 pounds on Neptune.

Step-by-step explanation:

The question is asking us to determine the weight of a dog on Neptune if the dog weighs 9 pounds on Earth. We know from the information given that an object that weighs 1 pound on Earth weighs 1.19 pounds on Neptune. To solve this, we multiply the Earth weight of the dog by the ratio of the weight on Neptune to the weight on Earth.

Weight on Neptune = Weight on Earth × (Weight on Neptune / Weight on Earth for the same object)

Weight on Neptune = 9 pounds × 1.19

Weight on Neptune = 10.71 pounds

Therefore, a dog that weighs 9 pounds on Earth would weigh 10.71 pounds on Neptune.
