The quantity that is present after 2000 years will be A. 7.851 grams.
<h3>How to calculate the quantity?</h3>
From the information given, initially at t = 0, the quantity is 10 grams.
After 2000 years, the appropriate quantity will be:
Q(2000) = 10 (1/2) × (2000/5730)
Q(2000) = 7.851 grams.
In conclusion, the correct option is A.

Answer:
3x + x + 100° = 180°
⇔ 4x = 80°
⇔ x = 20°
Step-by-step explanation:
Variables are the letters in the equation (like x and y)
Coefficients are the numbers before the variables. (like "6" in "6x")
Constants are the actual numbers (like "2" or "1")
Factors: Numbers that are multiplied together (like "5" and "6" in 5 * 6)
5) 4b + 6
Variable: b
Coefficient: 4
Constant: 6
6) 7x + 8h - 3
Variables: x, h
Coefficients: 7, 8
Constants: -3
7) 12 + 2a + 5b
Variables: a, b
Coefficients: 2, 5
Constants: 12
8) 5 + (7 * 8)
Factors: 7 and 8

Answer:
Step-by-step explanation:
Ms Fowler's ratio would be 8:7 and Ms Rivera's would be 16:15, they are not equivalent because the numbers didn't come out to the same ratio when i divided them and 16 and 1 aren't divisible by the same numbers.
here are the steps i took:
1. wrote down the original ratios (16:15 and 64:60)
2. I divided all the numbers by 2 and got them reduced to 8:7 and 30:32
3. I saw that the 8:7 couldn't be divided anymore, so I left it and divided 30 by 2 and 32 by 2 and got 16:15
4. I saw that I couldn't divide those anymore so I compared the ratios and saw that they were not the same so they weren't equal.
hope this helped!
