Answer:
16
Step-by-step explanation:
This question can be modeled using the equation 3x+4=52 (x is the purple marbles). To solve this equation subtract 4 from both sides, making it 3x=48. divide both by three showing x=16. This shows that 16 is the answer.
X = 6
9/12 = 0.75
6/8 = 0.75
Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>
Answer:
Ramon pays $240.
Step-by-step explanation:
30% of $960 is $288, so Glen pays $288
0.45 = 45%
45% of $960 is $432, so Andre pays $432
30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.
25% of $960 is $240. So, Ramon pays $240.
You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.
Answer:
G
Step-by-step explanation:
Try to understand what this equation is saying and what plugging in different values would represent.
At x=0, b(0)=850; which means the initial balance is $850. So H is incorrect.
At x=1, b(1)=871.25; which means that after 1 year, the initial balance will have increase to $871.25. So J is incorrect.
Since the initial vacation of 850 is being multiplied by a factor which is greater than one, the balance will be increased each year. So F is incorrect.
Finally, if we look at the factor by which we are multiplying, do a simple Algebraic step, and convert it into percentages we get:
1.025 = (1 + 0.025) = 100% + 2.5%
Essentially this is showing us that the balance will increase by 2.5% on however much is in the account each year.
So G is your answer.
