The answer is 18,27 and 45
Answer:
<em>The jar contains 156 grams of zinc</em>
Step-by-step explanation:
<u>Ratios</u>
Let's call
Z=gr of zinc
C=gr of copper
We know the ratio between them in a certain chemical is:

The jar of the chemical contains C=663 gr of copper. Calculate the grams of zinc by solving the above relation for Z:
Multiplying by C:

Substituting the value of C:

Z=156 gr
The jar contains 156 grams of zinc
Answer:
m<1 = 35. m<2=75
Step-by-step explanation:
its pretty simple fractional solving in this problem
Volume is measured in cubic units.
So the ratio would become 6^3: 5^3 = 216:125
The answer would be A.
Answer:
A. Yes
B. No
Step-by-step explanation:
We have that,
A. The dimensions of the each of the paper is 8.5 × 11.
Since, the papers have equal dimensions, the weight of every paper will be same and it will be easy to find the number of papers using direct proportion.
Thus, the weight of the paper and the number of papers is proportional.
B. It is given that the weight of each book is different.
Since, all the books have different weights, it is not easy to find the number of papers using direct proportion.
Hence, the weight of the books and the number of books is not proportional.
