0.9

The first step is to label the points being (1,2.3),(6,6.8) in which the first ordered pairs is the number of weeks, and the second one is the dollars in millions.

Hence, the slope is: m=(6.8-2.3)/(6-1) = 4.5/5 = 9/10 = 0.9

The slope represents the dollar rate in the millions per week. In this case, the movie grossed $0.9 million per week from week one to the sixth week.

A privately owned lake contains two types of game fish, bass and trout. The owner provides two types of food, A and B, for these
Vinvika [58]

Answer:

133 fishes

Step-by-step explanation:

Units of food A = 400 units

Units of food B = 400 units

Fish Bass required 2 units of A and 4 units of B.

Fish Trout requires 5 units of A and 2 units of B.

i. For food A,

total units of food A required = 2 + 5

                                                 = 7 units

number of bass and trout that would consume food A = 2 x \frac{400}{7}

                                               = 114.3

number of bass and trout that would consume food A = 114

ii. For food B,

total units of food B required = 4 + 2

                                                = 6 units

number of bass and trout that would consume food B = 2 x \frac{400}{6}

                                                 = 133.3

number of bass and trout that would consume food B = 133

Thus, the maximum number of fish that the lake can support is 133.

Que presion manométrica debe de producir una bomba para subir agua del fondo del gran cañon ( elevación 730 m ) a indian gardens
Alexxandr [17]

Answer:

La presión manométrica debe ser 6,272,000 Pa = 61.9 atm

Step-by-step explanation:

La presión absoluta se refiere al valor de presión referido al cero absoluto o al vacío, sin presión atmosférica. Es decir, la presión absoluta es la presión con respecto al vacío total.

La presión manométrica es la que ejerce un medio distinto al de la presión atmosférica y representa la diferencia entre la presión real o absoluta y la presión atmosférica. Es decir, la presión manométrica se mide en relación a la presión atmosférica y se define como la diferencia entre presión absoluta (Pabs) y presión atmosférica predominante (Patm). La presión manométrica sólo se aplica cuando la presión es superior a la atmosférica.  

Entonces,  Pmanometrica = Pabs – Pamb

Para encontrar la presión a una profundidad h en un líquido sin movimiento, expuesto al aire cerca de la superficie de la Tierra, la presión manométrica puede ser calculada mediante:

Pmanometrica=ρ*g*Δh

donde ρ es la densidad del fluido, g la gravedad y Δh la variación en la altura.

En este caso:

  • ρ=1000 \frac{kg}{m^{3} } (densidad del agua)
  • g= 9.8  \frac{m}{s^{2} }
  • Δh=hfinal - hinitial= 1370 m - 730 m= 640 m

Reemplazando:

Pmanometrica=  1000 \frac{kg}{m^{3} } *9.8 \frac{m}{s^{2} } * 640 m

Resolviendo:

Pmanometrica= <u><em>6,272,000 Pa = 61.9 atm</em></u> (siendo 1 pascal = 9.869*10⁻⁶ atmósferas )
