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.

What is the slope of a line that is perpendicular to the line 2y – 3x = 8?
GarryVolchara [31]

Answer:

= \frac{3}{2}

Step-by-step explanation:

y = mx + c

Here,

<h2>m => slope</h2><h3>c => intercept</h3>

In this equation ,

2y - 3x = 8

to find the value of m or the value of slope we have to solve for y

<em>Let's</em><em> </em><em>solve</em><em>,</em>

<em>2y - 3x = 8 \\ 2y = 8 + 3x \\  \frac{2y}{2}  =  \frac{8 + 3x}{2}  \\ y = 4 +  \frac{3x}{2}  \\  y =  \frac{3x}{2}  + 4</em>

<em>So</em><em>,</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>slope</em><em> </em><em>is</em><em>,</em>

<em>= \frac{3}{2}</em>
