Answer:
58 seconds
Step-by-step explanation:
Given:
Initial mass of water = 1 kg
Specific energy = 2297 kJ/kg
Heat supplied by the stove = 20 kJ/s
Now,
Half water is to be vaporized i.e 0.5 kg
Thus, heat required for vaporizing 0.5 kg water = mass × specific heat
or
heat required for vaporizing 0.5 kg water = 0.5 × 2297 = 1148.5 kJ
Therefore,
time taken to provide the required heat = 
or
time taken to provide the required heat = 
or
time taken to provide the required heat = 57.425 ≈ 58 seconds
<span>x^2 + 22x + 121 = 9 + 121 ..............a^2 + 2ab + b^2 = (a+b)^2
(x + 11)^2 = 130
answer
</span><span>you must add 121 to complete the square</span>
El celular de contado costará 7500 pesos, mientras que el celular a crédito tendrá un costo de 9000 pesos.
<h3>¿Cuál es el 20% de 7500?</h3>
7500 / 100 = 75 (valor del 1%)
75 x 20 = 1500 pesos
<h3>¿Cuánto cuesta cada celular?</h3>
Celular a contado: El precio no aumenta por lo que el valor sería de 7500 pesos.
Celular a crédito: 7500 + 1500 = 9000 pesos
