Answer:
To convert centimeters to meters, multiply the centimeter value by 0.01 or divide by 100. For example, to find out how many meters there are in 10 centimeters, multiply 10 by 0.01, that makes 0.1 meter in 10 cm. What is a Centimeter? Centimeter (centimetre) is a metric system length unit. 1 cm = 0.01 m.

Answer:
$ 2.167
<h3>
Step-by-step explanation:</h3>
Let the cost of a pencil be x and that of a pen be y.
A pen costs <u>twice</u> as much as a pencil.
==> cost of a pen = 2 × cost of a pencil
==> <u>y = 2x</u>
Their total cost is $6.50
==> x + y = $6.50
<em>since</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em>x</em><em>,</em><em> </em><em>substituting</em><em> </em><em>y</em><em> </em><em>for</em><em> </em><em>2</em><em>x</em>
==> x + 2x = 6.50
==> 3x = 6.50
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em>
==> x = 2.16
As per our assumption, x is the cost of one pencil.
Therefore, the cost of a pencil is <u>$2.16</u><u>7</u>
Answer:
$344.04
Step-by-step explanation:
The markdown multiplies the price by (1 -40%) = 0.60.
The tax multiplies the price by (1 +10%) = 1.10.
The two factors applied to the price make the final price be ...
$521.28·0.60·1.10 = $344.04
The total cost of the surfboard was $344.04.
7/9 = 0.77
-0.8
sqrt 3 = 1.73
least to greatest : -0.8, 7/9, sqrt 3
