Responder:
<h2>
$ 108.5
</h2>
Explicación paso a paso:
Paso uno:
datos dados
el costo de un metro de cinta tricolor = $ 15.5.
se nos dice que un lazo necesitará 3,5 m de cinta, ya que tu madre hizo dos lazos, usó un total de 3,5 * 2 = 7 m de cinta
Segundo paso:
ahora calcularemos el dinero que gastó su madre.
si 1 m le costará $ 15.5
entonces 7 millones le costarán $ x
Cruz multiplicar tenemos
x = 15,5 * 7
x = $ 108.5
<u>Esto significa que tu madre gastará $ 108.5 para hacerte los dos moños.</u>
Newton's law of cooling states that under forced convection (which is assumed to be true), then
dT(t)/dt = -k(T(t)-Ta)..............(1)
T(t)=temperature
Ta=ambient temperature=40F
k=cooling constant = 0.1947
T(0)=98.6F (assuming victim did not have fever)
Integrate (1)
T(t)-Ta=(T(t)-T(0))e^(-kt)
Solve for t
(T(t)-Ta)/(T(t)-T(0)) = e^(-kt)
take log:
-kt=log_e((T(t)-Ta)/(T(t)-T(0)))
substitute T(t)=80F, Ta=40F,T(0)=98.6F
-kt=log_e((80-40)/(98.6-40))=-0.38186
t=0.38186/0.1947
=1.96, or almost 2 hours (assuming k=0.1947 is in hours)
I would help you, but sadly, i cannot read what the paper states.
