Find out the wrong number in the sequence. <br> 623, 251, 543, 356

Jet001 [13]

I think the wrong number is 623.

Solution:
623 => 6 + 2 + 3 = 11
251 => 2 + 5 + 1 = 8
543 => 5 + 4 + 3 = 12
356 => 3 + 5 + 6 = 14.

Except 11 all other numbers are even.So, 623 is the wrong number.

The fraction of the image in blue with respect to the <em>entire</em> hexagon is $\frac{1}{3}$ .

<h3>Estimation of the ratio of the shaded region area to the entire area</h3>

Initially we proceed to create auxiliar constructions , represented by red line segments, to re-define the hexagon as a sum of standard figures. According to the figure, we find two types of triangles (type-1 and type-2), and the following relationship between the two types:

$A_{1} = A_{2}$ (1)

Where:

$A_{1}$ - Area of a type-1 triangle.
$A_{2}$ - Area of a type-2 triangle.

The formulae for the area of the shaded region ( $A_{s}$ ) and the <em>entire</em> hexagon ( $A_{h}$ ) are, respectively:

<h3>Shaded region</h3>

$A_{s} = 2\cdot A_{1} + 4\cdot A_{2}$ (2)

<h3>Entire hexagon</h3>

$A_{h} = 8\cdot A_{1} + 10\cdot A_{2}$ (3)

And the fraction of the image in blue is:

$\frac{A_{s}}{A_{h}} = \frac{2\cdot A_{1}+4\cdot A_{2}}{8\cdot A_{1}+10\cdot A_{2}}$

$\frac{A_{s}}{A_{h}} = \frac{6\cdot A}{18\cdot A}$

$\frac{A_{s}}{A_{h}} = \frac{1}{3}$

The fraction of the image in blue with respect to the <em>entire</em> hexagon is $\frac{1}{3}$ . $\blacksquare$

Janelle plans to buy three boxes of popcorn for herself and 2 friends. If each box costs $1.95 how much change will she receive

Sophie [7]

First you would do 1.95 * 3 which would equal to 5.85, then you would do 10.00-5.85 which equals to 4.15
Answer: She would receive $4.15 as change if she payed with a $10 bill.
