Answer:
Costo Total= $38,680
Step-by-step explanation:
Dada la siguiente información:
Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una.
<u>Para calcular el costo total, debemos usar la siguiente formula:</u>
Costo Total= costo unitario * cantidad adquirida
Costo Total= 408*16 + 732*27 + 652*19
Costo Total= $38,680
<span>32 tens means 32 times ten. This is 32 * 10 = 320. So the number with the same value as 32 tens is 320 units. You could use this way to write other forms of 32 tens, for example you could find the numbers of hundreeds that represent the same value, That would be 3.2 hundreeds, because 3.2 * 100 = 32 * 10 = 320. </span>
9 = 3^2
Since 3 squared equals 9, that is how 9 as a power of the base 3 should be written.
Answer:
247.12 million
Step-by-step explanation:
Given:
In 1990, population=242 million
In 1999, population=244 million
estimated population in 2013=?
Estimated growth is calculated by:
P(t)= Po*e^(kt)
where Po is original population
k is growth rate
t is the time in year
Now putting the values of Po=242, P(t)=244, t=9 (t=1999-1990=9) we have:
244=242e^(9k)
(244/242)=e^(9k)
ln(244/242)=9k
k=1/9ln(244/242)
k=0.00091
Now Putting k=0.00091, Po=242, and t=23 (t=2013-1990=23) we have:
P(t)=242e^(23*0.00091)
P(t)=247.12 million
the population in 2013 estimated to be 247.12 million!
