Answer:
1/3
Step-by-step explanation:
Turned 20 minutes, so the minute hand turned 20 times per hour
There are 60 minutes in 1 hour, so the minute hand turns 60 times per hour
Therefore, the fraction is 20/60, simplified to 1/3
You first set up a proportion
16/100 = x/90
then cross multiply 16*90
and 100*x
1440 = 100x
divide each side by 100
1440/100 = 100x/100
100 cancels out on the right side
the answer is
14.4=x
- transvers-al so from this result tha is a line and that intersect two or more coplanar lines
20 x 8.55= 171 that is what tracy was making per week.
8.55 + 1.30= 9.85 is her raise
20 x 9.85= 197 is how much she making with her new raise per week.
now to figure out how much MORE she is making go 197 - 171=$26 is your final answer
Answer:
4
Step-by-step explanation:
This is an <em>infinite geometric series</em>. This has a sum of 
Where
a is the first term, and
r is the common ratio (one term divided by the previous term)
Let's figure out the first 2 terms by plugging in n = 1 first and then n = 2 for the series.
<u />
<u>First term:</u>

<u>Second term:</u>

<em>Let's see the common ratio:
</em>
<em />
<em>Thus we have a = 3 and r = 1/4</em><em>. Plugging into the formula of the infinite sum, we get:</em>
<em>
</em>
<em />
<em>So, </em><em>the answer is 4</em>
