In order to use the simple interest formula, we first define the variables. The interest would be equal to Samuel's desired amount $ 2,488 minus the principal amount of $ 1,800 which is then equal to $ 688. The rate must be in decimal form which is equal to 0.12 while t is expressed in years. Substituting the values, t is equal to 3. Thus, it will take 36 <span>months for Samuel's account balance to reach $2,448. </span>
Answer:
512
Step-by-step explanation:
8 x 8 x 8 = 512
X = Dimes Y = Nickels
x + y = 175
.10x + .05y = 13.30
Answer:
Equation: $114.90 + $1.85<em>x</em> = 200
Solution: They can buy 46 tiles.
Step-by-step explanation:
First, subtract 114.90 from both sides to get 1.85<em>x</em> = 85.10.
Divide 85.10 by 1.85 to get 46, which is the answer.
To take out terms outside the radical we need to divide the power of the term by the index of the radical; the quotient will be the power of the term outside the radical, and the remainder will be the power of the term inside the radical.
First, lets factor 8:
Now we can divide the power of the term, 3, by the index of the radical 2:

= 1 with a remainder of 1
Next, lets do the same for our second term

:

= 3 with a remainder of 1
Again, lets do the same for our third term

:

with no remainder, so this term will come out completely.
Finally, lets take our terms out of the radical:

We can conclude that the correct answer is the third one.
