Five different problems in one post? That's a turn-off for some potential helpers. Suggest you post only ONE problem at a time.
In regard to the first problem: Your Principal (P) is $8000. The Interest Rate (i) is 19%. The elapsed time is 7 years. Using the formula for continuous compounding:
A = P e^(rt), where "e" is the very common base with value approx. 2.718.
Here, the amount due is A = $8000 * e^(0.19 * 7). Can you evaluate this?
Answer:
48/30 3/18 40/16 6/9 21/49 20/15 18/24 30/25 8/16
Step-by-step explanation:
Find the common denominator, then whatever it is, multiply the top to match it. For examples you start with 7/5 and you are trying to get the denominator to 25, you would multiply 7x5 which equals 35/25. Hope this helps.
13 tens is 130
<span>100+10+10+10=130
</span>or
100+30=130
you can do it either way
