Tom compared \dfrac{2}{12} 12 2 ​ start fraction, 2, divided by, 12, end fraction and \dfrac{7}{6} 6 7 ​ start fraction, 7, divi

ded by, 6, end fraction by first comparing each fraction to \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction and 111. Step 1: \dfrac{2}{12} 12 2 ​ start fraction, 2, divided by, 12, end fraction is less than \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction. Step 2: \dfrac{7}{6} 6 7 ​ start fraction, 7, divided by, 6, end fraction is less than 111 but more than \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction. Step 3: So, \dfrac{2}{12} < \dfrac{7}{6} 12 2 ​ < 6 7 ​ start fraction, 2, divided by, 12, end fraction, is less than, start fraction, 7, divided by, 6, end fraction In which step did Tom make his first mistake?

explain how you can find the height of a cylinder if you know the diameter and the volume. include an example with your explanat
ZanzabumX [31]
To find the height you need to take the volume, and the radius (halve the diameter to get the radius) and use the same formula that would be to find Volume and when you plug in the volume and radius you take the radius and solve it with the exponent. Then you take the solved radius and you multiply it with 3.14. After that you then divide the volume by the multiplication.
V=(3.14)(r^2)h
Example:
V=87.92m^3
pi=3.14
r=2m
h=?

87.92=(3.14(2)^2)h
87.92=(3.14(4))h
3.14*4=12.56
87.92/12.56=7
h=7m

A child that is 1.4 meters tall is standing next to a flagpole. The child's shadow is 1.2 meters long. At the same time, the sha
koban [17]

The flag pole is 8.75 \: m or write it as 9 \: m tall.

Step-by-step Explanation:

Let "p" be the height of the flag pole.

The ratio of the child height to the pole height is the same as the ratios of their respective shadows, so,

\frac{1.4}{p} =  \frac{1.2}{7.5}

Now, Cross multiply :-

1.2 \times p = 1.4 \times 7.5

→ 1.2 \times p = 10.5

→ p =  \frac{10.5}{1.2}

→ p = 8.75

This 8.75 can be rounded off to 9 as it ends with .75

So, the flag pole is <u>9 metres</u> tall.
