Answer:
b. 14
Step by step explanation:
First we have to calculate the half-life
half-life = elapsed time * log (2) / log (bgn amt / end amt)
half-life = 1 hour * 0.30102999566 / log (1 / .95)
half-life = 0.30102999566 / log (<span>
<span>
<span>
1.0526315789 )
</span>
</span>
</span>half-life = 0.30102999566 / 0.022276394692
half-life = <span>
<span>
<span>
13.5134073454 hours
</span>
</span>
</span>
Ending Amount = Beginning Amount / 2^n
Where "n" = number of half-lives
For 4 hours, "n" equals
4 / 13.5134073454
=<span>
<span>
<span>
0.2960023255
</span></span></span>Ending Amount = 500 grams / 2^.2960023255
Ending Amount = 500 grams /<span>

1.2277376629
</span>
</span>
</span>Ending Amount = <span>

Answer:
Answer key:
The change in the scale factor is <em>4/5.</em>
12 / 15
12 ÷ 3 = 4
15 ÷ 3 = 5
4/5
Answer key: The change of scale means that 1 inch represented 4 feet, but now 1 inch represents <em>5 feet.</em>
1 inch represents 4 feet which factors 12 feet.
4 cannot factor 15 feet.
5 can factor 15 feet.
1 inch would represent 5 feet then.
15 ÷ 5 = 3 inches
Answer:
114y times 3x
Step-by-step explanation:
cancel it down to its lowest possible form so 228 decided by 2 is 114 and what you do to one side you do to another so 6 decided by 2 is 3 so if y is the miles you have 114 miles so 114y time x witch is 3 so x is 3
