Hope its right.
1. What you want to do is do is to know 2x is the ratio and x; $140,000 is the 1 brother investment and total is $1,600,000
2. Put them together 2x (140,000 + x + 2x) = 1600,000
3. 280,000 + 2x + 4x = 1600,000
4. 280,000 + 6x = 1600,000
5 1600,000-280,000= 1320,000 /6
6. They each invested $220,000

The atomic weight of the new element is simply the weighted average of the isotopes. So
0.4030 * 296.78 + 0.5970 * 300.88
= 119.60234 + 179.62536
= 299.2277
Now the number of significant digits is the same as the number of significant digits of the LEAST PRECISE DATUM. And that would be the percentages at 4 significant digits each. So the result needs to be rounded to 4 significant digits which is 299.2</span>
Answer:
Step-by-step explanation:
Let L represent the number of laptops and B represent the number of Bicycles.
We are told that each laptop is worth $200, so price of L laptops will be 200L.
We are also told that each bicycle that Hyun Yong donates is worth $100, so B bicycles will be worth 100B dollars.
We are told that Hyun Yong wants to donate more than$5000 in laptops and bicycles. This means that total cost of L laptops and B bicycles should be greater than 5000.
We can represent this information in an inequality as:
Therefore, the inequality represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.
E
Because if you do the math
Do you mean ounce or once
