zubka84 [21]

Answer:

$92.43

Step-by-step explanation:

Original value of money paid is $79

Tip is 17% of $79 = $13.43

Total is the original value + the tip

79 x 0.17(this is because 17% is the same as 17/100 If you turn this to a decimal you get 0.17) = $13.43

Total = $13.43 + $79

$92.43 the 43 cents are whole so there is no need to round off.

Answer:

<h2>b = 8</h2>

Step-by-step explanation:

\text{Use}\ \log_ab=c\iff a^c=b,\ \text{for}\ a>0,\ b>0\ \wedge\ a\neq1\\\\Domain:b>0\ \wedge\ b\neq1\\\\\log_b(512)=3\iff b^3=512\to b=\sqrt[3]{512}\\\\\begin{array}{c|c}512&2\\256&2\\128&2\\64&2\\32&2\\16&2\\8&2\\4&2\\2&2\\1\end{array}\\\\512=2^9=2^{3\cdot3}=(2^3)^3=8^3\\\\\text{Therefore}\ b=\sqrt[3]{512}=\sqrt[3]{8^3}=8\in D

\text{Used:}\\\\(a^n)^m=a^{nm}\\\\\sqrt[n]{a^n}=a

yanalaym [24]

Answer:

Interestingly, the likelihood of a randomly chosen student being a female is <u><em>0.58</em></u> at this school.

Step-by-step explanation:

This school features more female students than male students. <em>Consequently, if resources are allocated equally (because it has been found that both female and male male students are similarly likely to be involved), the number of female students involved in after-school athletics programs is greater than the number of male students and could clarify the facilities issues.</em>
