I'm not even that high level sorry
3 hundreds is 300, 17 tens is 170, and 2 ones is 2. You add them all and then you get 472.
Answer:
3 obreros tardaran 225 minutos en completar el trabajo.
Step-by-step explanation:
Sea R la velocidad con la que un obrero puede construir 1 muro.
Sabemos que 15 obreros construyen un muro en 45 minutos, entonces:
(15*R)*45min = 1 muro
Con esta ecuación podemos encontrar el valor R
R = (1 muro)/(15*45min)
Ahora queremos saber cuando tiempo tardan 3 obreros en construir un muro, entonces tenemos que resolver:
(3*R)*T = 1 muro
Reemplazando el valor de R obtenemos:
(3*(1 muro)/(15*45min))*T = 1 muro
T = (1 muro)*(15*45 min)/(3*1 muro)
T = 5*45min = 225 min
3 obreros tardaran 225 minutos en completar el trabajo.
Answer:
Choice A:
Step-by-step explanation:
means we looking for first term 5 and the sequence is going up by 2.
In general,
means you have first term 
and the sequence has a common difference of d.
So it is between the first two choices.
The explicit form of an arithmetic sequence is:
An equivalent recursive form is 
So d again here is 2.
So choice a is correct.
