In a paper airplane contest, Marcel's paper airplane travel 3.345 meters. Salvador's plane travels 3.35 meters. Jennifer's plane travels 3.3 meters. Based on their measurements, whose plane traveled the farthest distance? Whos plane traveled the shortest distance? Explain your reasoning using a place value chart.

Farthest distance = Salvador's

Shortest distance = Jennifer's

Step-by-step explanation:

Given the following :

Marcel's paper airplane = 3.345

Salvador's plane = 3.35 meters

Jennifer's plane = 3.3 meters

Unit = u

Tenth= te

Hundredth = hth

thousandth = th

u__tehthth

Marcel3__345

Salvador___ 3__350

Jennifer ___ 3__300

All inputs have the same unit and tenth value,

Hence, the input with the greatest hundredth value is largest and hence has the Farthest distance while the input with the least hundredth value will have the shortest distance.

Whose plane traveled the Farthest distance = Salvador (5 in hundredth place)

Whose plane traveled the shortest distance = Jennifer ( 0 in hundredth pace)

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
