Answer: 426.5

Step-by-step explanation:

You know that she spent 34.12 on gas and you also know that that amount of money was the 8% of her paycheck.

Therefore, keeping the above on mind, you can write the following expression, where $x$ is the total amount of money of her paycheck:

$0.08x=34.12$

When you solve for $x$ , you obtain the result shown below:

$x=\frac{34.12}{0.08}\\\\x=426.5$

Bond [772]

Chi would have two thousand nickels because if 100 nickels is 5% and 100 divided 5 is 20 so a 100 times 20 is 2000

I need help please.

Answer:

13 - 17 $\sqrt{11}$

Step-by-step explanation:

Using the rule

$\sqrt{a}$ × $\sqrt{a}$ = a

Each term in the second factor is multiplied by each term in the first factor, that is

2 $\sqrt{11}$ ( $\sqrt{11}$ - 9 ) + 1 ( $\sqrt{11}$ - 9 )

Distribute both parenthesis

= (2 × 11) - 18 $\sqrt{11}$ + $\sqrt{11}$ - 9

= 22 - 17 $\sqrt{11}$ - 9

= 13 - 17 $\sqrt{11}$

For f(x)=0.01(2)power of x, find the average rate of change from x=3 to x=8

sineoko [7]

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
f(x)= 0.01(2)^x \qquad 
\begin{cases}
x_1=3\\
x_2=8
\end{cases}\implies \cfrac{f(8)-f(3)}{8-3}
\\\\\\
\cfrac{0.01(2)^8-0.01(2)^3}{8-3}$
