A pencil case with a cylinder shape with diameter= 10 cm
Mila [183]

Answer:

length of the longest pencil that can fit must be less than 13cm

Step-by-step explanation:

To get the longest pencil that fit the case, we will use the pythagoras theorem;

diameter = 10cm

radius = 10/2

radius = 5cm

Height = 12cm

Get the length of the longest side

l² = r²+h²

l² = 5²+12²

l² = 25 + 144

l² = 169

l = √169

l = 13cm

Hence the length of the longest pencil that can fit must be less than 13cm

Simplify the expression<br> -2/3(12c - 9) + 14c
postnew [5]
Greetings!

Simplify the Expression.
=\frac{-2}{3}(12c-9)+14c

Distribute the Parenthesis.
<em>How?</em> <span>Multiply the terms inside the Parenthesis by the term outside of the Parenthesis.
</span>=\frac{-2}{3}*12c-\frac{-2}{3}*9+14c

=\frac{-2}{3}*\frac{12}{1}c-\frac{-2}{3}*\frac{9}{1}+14c


=\frac{-24}{3}c-\frac{-18}{3}+14c

Combine Like Terms.
=\frac{-24}{3}c+\frac{14}{1}c-\frac{-18}{3}

=\frac{18}{3}c-\frac{-18}{3}

Reduce to Lowest Terms.
=6c-6

The Answer Is:
\left[\begin{array}{ccc}=6c-6\end{array}\right]

Hope this helps.
