Determine the possible number of blue and red marbles
This question requires options. Since none were given, I'll answer on a general term.
To get the possible amount of each marble, we simply multiply the ratio by the same factor.
Take for instance.
Multiply ratio by 15



This means that:
and 
Another possible amount is: <em>multiply by 10</em>



This means that:
and 
<em>So, all you need to do is to multiply by the same factor</em>

Step-by-step explanation:
Answer:
270.06
How to solve:
Write a function:
f(t)=270(1+0.001)^{t/10}
23 years→23/10→2.3 decades
Plug in t=2.3
f(2.3)=270(1+0.001)^{2.3/10}
=270.062076106
≈270.06
Answer:
x=1
Step-by-step explanation:
you can also use mathpapa it's a calculator that gives you the answer and solves it for you step by step.
To get the answer do this:
2.5% of what is 2.21
2.5%x = 2.21
2.5/100x = 2.21
0.025x = 2.21
divide both sides by 0.025
0.025x/0.025 = 2.21/0.025
x = 88.4
