Answer:
Interest: $390 | Total: $715
Step-by-step explanation:
To answer the first question, we can use the simple interest formula provided:
<em>P = initial balance</em>
<em>r = annual interest rate</em>
<em>t = time</em>
<em />
First, change 8% into the decimal form:
8% -> 
-> 0.08
Now, plug in the values:
Charlie made $390 of interest. To find the total, just add that number to $325.

Answer:
x = 12.75
Step-by-step explanation:
10.2 : x = 0.8
x = 10.2 : 0.8
= 102/10 : 8/10
= 102/10 × 10/8
= 102/8
= 12.75
Couldn't you use pi • r^2•height
That's the cylinder formula.
Or you could use the cone formula
pi•r^2•height/3
Answer:
the third num equation has no solution i guess
Answer:
The answer would be 19. I think. I am not so good at mathematics. I just added 19 to -3 and got the answer of 16.
Step-by-step explanation:
16 - 19 = -3
That's all..
