A unit rate is just how much it costs per ONE unit of whatever your measuring. Lets say you had a rate of $4.00/8lbs. The unit rate would be $0.50/ ONE lb.

Shade a model that shows 0.674

Ratling [72]

0.674 means that it 674/1000

which mean that if the model consists of 1000 squares, you have to shade 674 of the squares.

If the model consists of 500 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)

What is the inverse of the function f(x) = 4x + 8?

Viktor [21]

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$ :

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$ :

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$

How much more interest is owed on $900 for 9 months then for 6 months? 6 months = 2.4% rate 9 months = 2.9% rate

stiv31 [10]

Keeping in mind that 6 months is not even a year, since there are 12 months in a year, then 6 months is really 6/12 years, and 9 months is 9/12 years, then

$\bf ~~~~~~ \textit{Simple Interest Earned on 9 months}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 2.9\%\to \frac{2.9}{100}\to &0.029\\
t=years\to \frac{9}{12}\to &\frac{3}{4}
\end{cases}
\\\\\\
I=900(0.029)\left( \frac{3}{4} \right)\\\\
-------------------------------$

$\bf ~~~~~~ \textit{Simple Interest Earned on 6 months}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 2.4\%\to \frac{2.4}{100}\to &0.024\\
t=years\to \frac{6}{12}\to &\frac{1}{2}
\end{cases}
\\\\\\
I=900(0.024)\left( \frac{1}{2}\right)$

check their difference, that much.
