  • Radius=r=0.7m
  • Volume=231m^3
  • Height=h

\boxed{\sf Volume=\pi r^2h}

\\ \sf\longmapsto π(0.7)^2h=231

\\ \sf\longmapsto 0.49πh=231

\\ \sf\longmapsto πh=\dfrac{231}{0.49}

\\ \sf\longmapsto 3.14h=471.4

\\ \sf\longmapsto h=\dfrac{471.4}{3.14}

\\ \sf\longmapsto h=150m

Which of these is longest distance 0.1203km or 123m or 1230cm or 12030mm
bogdanovich [222]
<h3>Answer: 123 meters is the longest </h3>

============================

Work Shown:

Convert everything to the same unit. I'm going to convert everything to meters

0.1203 km = 120.3 meters (multiply by 1000)

1230 cm = 12.3 meters (divide by 100)

12030 mm = 12.03 meters (divide by 1000)

------------------

The four distances we have are: 120.3 meters, 123 meters, 12.3 meters, 12.03 meters. We see that 123 meters is the longest.

Consider each of the following relationships. Which school shows the greatest rate of change between male and female students?
ratelena [41]

Answer:

The school C shows the greatest rate of change between male and female students

Step-by-step explanation:

Let

x -----> the number of female students

y ----> the number of male students

we know that

The ratio of male students to female students is

\frac{y}{x}

we have

<em>School A</em>

\frac{y}{x}=\frac{4}{1}=4

<em>School B</em>

\frac{y}{x}=\frac{4}{3}=1.33 ----> the slope of the linear equation

<em>School C</em>

\frac{y}{x}=\frac{1,260}{280}=4.5

so

4.5 > 4 > 1.33

therefore

The school C shows the greatest rate of change between male and female students
