Answer:
that is 81 which is 9 ^2 and you can you use
Step-by-step explanation:
(a^2 -b^2)=(a-b)(a+b)
=(9^2-8^2)
=(9-8)(9+8)
First, set up an equation to model the problem. I will use the simple interest formula: I = (P)(r)(t); where P = principle amount, r = interest rate, and t = time.
First, substitute the known values into the formula:
P = $250
r = 0.3% = 0.003
t = 2
I = (250)(0.003)(2)
Now, all we have to do is simplify to find the amount of interest that will be added to Sydney's account after two years.
I = (0.75)(2)
I = 1.5
After two years, $1.50 will be added to Sydney's account. To find the total amount of money she will have after that time, just add the interest to her initial deposit:
250 + 1.5 = 251.50
So, your final answer is...
After two years, Sydney will have $251.50 in her account.
Hope this helps!
Answer:
X=10
Step-by-step explanation:
x+10-10=2x-10
x=2x-10
x-2x=2x-10-2x
-x= -10
-x/-1= -10/-1
x=10
Answer:
-12x+27
Step-by-step explanation:
Use distrubutive property.
-3(4x-9)
-3 * 4x = -12x
-3 * (-9) = 27
Hence -12x+27.
Hope this helps!! :P
Well first, it would be ideal to simply the exponent that is in the numerator. 9 to the third power is 729. Now we just divide by 2. Which would give us the final answer of
364.5
