The distance between Detroit, Ml to Paris, France is approximately 3930 mi. Flying from Detroit to Paris take 8 hr with the jet

slamgirl [31]

Answer:

a) $s=482moh$

b) $s'=9mph$

Step-by-step explanation:

From the question we are told that:

Distance $d=3930mi$

Time of flight $T=8hr$

Flight back $T_b=8.3hr$

Generally the equation for Time for flight with jet steam is mathematically given by

$T=\frac{d}{s+s_1}$

$8=\frac{3930}{s+s'}$

$s+s'=491.3 ....equ1$

Generally the equation for Time for flight against jet steam is mathematically given by

$T=\frac{d}{s-s_1}$

$8.3=\frac{3930}{s-s_1}$

$s+s'=473.5......equ 2$

Solving equ 1 and equ 2 simultaneously

$s+s'=491.3$

$s+s'=473.5$

Therefore

$s=482moh$

$s'=9mph$

. Calculate the loss on selling 50 shares of stock originally bought at 133/4 and sold at 12.

Aleks04 [339]

is simply the difference of both numbers of course, the price it was sold minus the price it was bought at.

$\bf \cfrac{133}{4}-12\implies \cfrac{133}{4}-\cfrac{12}{1}\implies \stackrel{\textit{our LCD will be 4}}{\cfrac{(1)133-(4)12}{4}}\implies \cfrac{133-48}{4}\implies \cfrac{85}{4}$
