Para encontrar el volumen del objeto que queda fuera del líquido, primero debemos determinar el volumen del objeto y luego restar el volumen de la porción que está sumergida en el líquido. Denotemos: - m como la masa del objeto (500 g) - ho_o como densidad del objeto (0,8 g/cm³) - ho_l como densidad del líquido (1,2 g/cm³) - V_o como volumen del objeto (por determinar) - V_s como el volumen de la porción del objeto sumergida en el líquido Sabemos que la densidad ho se define como ho = m/v A partir de esto, podemos reorganizar la ecuación para resolver el volumen: V = m/ho Para el objeto: V_o = m/ho_o Vo = 500/0,8 Vo = 625 cm ^ 3 Ahora, para encontrar el volumen de la porción sumergida en el líquido, podemos utilizar el hecho de que la masa del líquido desplazado es igual a la masa del objeto sumergido: m_desplazamiento = m_ objeto sumergido ho_l *V_s = m Podemos resolver para V_s: V_s = m/ho_l V_s = 500/1,2 V_s=416,67cm^3 Finalmente, para encontrar el volumen del objeto que queda fuera del líquido, restamos el volumen sumergido al volumen total del objeto: Volumen fuera del líquido = V_o - V_s Volumen fuera del líquido = 625 - 416,67 Volumen exterior del líquido = 208,33 cm^3 Entonces, el volumen del objeto que queda fuera del líquido es aproximadamente 208,33 cm^3.

The Humane Society has asked for our help again this week. Currently they are charging $50 for an adoption fee. Unfortunately they just pulled this number out of the air and do not know why they are charging this amount. They would like to charge an amount that covers all the adoption costs – both the variable costs for adoptions as well as the fixed cost for the kennel portion of the Humane Shelter operations. We can help them by doing a breakeven analysis. During a client meeting we gathered these facts. There are 2 part-time employees that each earn $1000 per month. The utilities for the kennel area (water, electricity) are $200 per month. The average food cost for animals in the kennel is $800 per month. In addition, each animal that is adopted receives a rabies vaccination that costs $4 and is micro-chipped that costs $6. At the current cost of $50, how many animals must be adopted to break-even? What would break-even be at a $60 adoption fee? What would break-even be if the fee were lowered to $40? The newspaper has suggested that the Humane Society advertise to increase pet adoptions. The package that they have recommended costs $1000 for a very small ad run every day for a month. If the Humane Society does this extra advertising, how will it affect breakeven? Based on what you have learned about elasticity, what price do you recommend for the adoption fee?
