PLZZZZZZ HELPPPPP

Answer 1

To find the amount of zinc in the jar, we can set up a proportion using the given ratio and the known amount of copper. Solving for x will give us the amount of zinc in the jar, which is approximately 152 grams.

Step-by-step explanation:

To find the amount of zinc in the jar, we first need to determine the ratio of zinc to copper. The ratio given is 4:17, which means for every 4 parts of zinc, there are 17 parts of copper. Now, we know that there are 646 grams of copper in the jar. To find the amount of zinc, we can set up a proportion using the given ratio: (4 parts zinc)/(17 parts copper) = (x grams zinc)/(646 grams copper)

To solve for x, we can cross-multiply and divide: 4 * 646 = 17 * x
2584 = 17 * x
x = 2584/17
x ≈ 152 grams of zinc

Therefore, the jar contains approximately 152 grams of zinc.
