Sam is determining the area of a triangle. In this triangle, the value for the height is a terminating decimal, and the value fo
snow_tiger [21]

Answer:

The area is rational because the numbers in the formula are rational.

Step-by-step explanation:

All repeating decimals are still rational because they can be expressed as fractions. For example,

$\frac{1}{7}=0.\overline{142857}$\end{document}

So every recurring decimal must be a fraction.

Also every terminating decimal can be represented as a fraction.

0.25  =  \frac{1}{4}

So  the area is rational because the numbers are rational.

Area = \frac{1}{2} X Base X Height

Base is Rational and Height is Rational. Hence Area=Rational.

When these rational numbers are substituted into the formula,the area must be rational.

Ms Bonilla is saving for a vacation she currently has 150 in her savings account and plans to add $25 to the account each week .
Alexandra [31]

Answer and Step-by-step explanation:

Alright, so when creating any type of math problem, it is important to identify the parts of the problem and where they go. First, we need to start by putting the problem together. We will use one of the most common forms of equations of math, also known as the linear equation of <em>y=mx+b.</em>

So we have: S(w)=__x + __. S(w) is also equal to f(x), which is also equal to y. So: y= __x + __.

Let's start filling this equation in. So, because it says that she will <em>add 25 dollars each week</em>, The problem is addition. Also, the 25 dollars each week will represent the mx in this situation. Here's why:

The x in this can stand for the amount of week she added this 25 dollars to her account. So:

y= 25x + __.

Now, we can add the 150 to the problem because that is what she started with for this one-time deal. So now we have:

y= 25x + 150.

You can now where everything is represented, but we are not done. Let's change y and x back into S(w) and w like the question asks us to have. So:

S(w)= 25w + 150.

If you want to solve this question, just replace the number of weeks in place of all w's in the equation, like this: S(2)= 25(2) + 150.

I hope that this helps.
