In a year, there are 4 months that have 30 days. What is the ratio of the months with 30 days to the months with other than 30 d

Inessa05 [86]

In a year, there's a total of 12 months. So if 4 of them have 30 days, then the rest don't: 12 - 4 = 8 months. So 8 months out of 12 don't have 30 days, and 4 out of 12 have 30 days.
So the ratio of the months with 30 days to the months with other than 30 days is 4/8. To simplify your answer, you divide both sides by 2 and you get a ratio of 1/2.

All in all, the ratio is 1/2.

Hope this helps! :)

Jens motorboat travels at a speed of 40 miles in Stillwater booth river flows at a speed of 4 mph how long will it take Jen to t

olganol [36]

Recall your d = rt, distance = rate * time.

bearing in mind that, when she's going downstream, she's not going 40 mph, she's going 40 + 4 mph, because the stream is adding its speed to it.

likewise, when she's going upstream, she's going 40 - 4 mph, because the stream is eroding speed from it, thus

$\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
Upstream&10&40-4&u\\
Downstream&10&40+4&d
\end{array}
\\\\\\
10=(40-4)u\implies \cfrac{10}{40-4}=u\implies \cfrac{10}{36}=u\implies \cfrac{5}{18}=u
\\\\\\
10=(40+4)d\implies \cfrac{10}{40+4}=d\implies \cfrac{10}{44}=d\implies \cfrac{5}{22}=d$

so, "u" is 16 minutes and 40 seconds.

and "d" is 13 minutes and about 38 seconds.
