The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7. How much would a person who weighs 150 pounds on Earth weigh on Neptune?
Thay would weigh 210 pounds because you divide 150 by 5 and you get 30 and then you plug that in and you do 7 times 30 and that is 210 so the ratio is 5:7,150:210
To find out how much a person who weighs 150 pounds on Earth would weigh on Neptune, we need to use the given ratio of 5:7.
1. First, we can express the ratio as a fraction: 5/7.
2. Next, we'll set up a proportion using the weight on Earth (150 pounds) and the unknown weight on Neptune (let's call it 'x'): 5/7 = 150/x.
3. To solve this proportion, we can cross-multiply: 5x = 7 * 150.
4. Simplify the right side to get: 5x = 1050.
5. Divide both sides by 5 to solve for x: x = 1050/5.
6. Calculating the result, we find that x = 210.
Therefore, a person who weighs 150 pounds on Earth would weigh 210 pounds on Neptune according to the given ratio.
