Because you are missing one whole side of the triangle
Right. The first 5 is in the tenths place, the second five is in the hundredths, and the third one is in the thousandths. I'd like to think that if you take away (divide 1000 by ten) a tenth from the thousandths, that would leave you with the 5 in the middle being one tenth the value of the five to its right. (I'm not sure if this is correct or not, i'm just making an assumption). I would check with someone to make sure
Answer:
The function would be
.This is in the general form
, where a is the initial value, b is the rate it increases by, and x is the amount of time. For our function, the initial value is 4 and the rate it increases by is 2.
Step-by-step explanation:
Responder:
24 litros; 16 litros; 4 litros
Explicación paso a paso:
Dado que:
Gasolina consumida = 20 litros
Sea la cantidad de gasolina en el tanque = x
Primera parte del viaje = 2/3 de x
Segunda parte del viaje = 1/2 de (x - 2x / 3)
Cantidad de gasolina en el tanque:
2x / 3 + 1/2 (x - 2x / 3) = 20
Solución para x
2x / 3 + x / 2 - x / 3 = 20
(4x + 3x - 2x) / 6 = 20
5 veces / 6 = 20
5 veces = 20 * 6
5 veces = 120
x = 120/5
x = 24
Cantidad de gasolina en el tanque = 24 litros
Litros consumidos en cada etapa:
Primera parte = 2/3 de 24 = 48/3 = 16 litros
2a parte = 0.5 de (24 - 16) = 0.5 * 8 = 4 litros
