Answer: False.

10 out of 40 is 1/4. 1/4 is 25%.

For example, four 25 cents equals one dollar.

So, <u>10 out of 40 is 25%.</u>

<u>Pre-Algebra</u>

Equality Properties

<u>Algebra II</u>

Exponential to Logarithmic: $\displaystyle b^m=x \rightarrow log_bx=m$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

0.77 = log(x)

<u>Step 2: Solve for </u><em><u>x</u></em>

[Equality Property] Raise both sides to the 10th power: $\displaysytle 10^{0.77} = 10^{logx}$
Simplify: $\displaysytle x = 10^{0.77}$
Evaluate: $\displaysytle x = 5.88844$
