1. Un proyecto habitacional Una contratista de viviendas ha subdividido una granja en 100 lotes para construcción. Ella ha diseñ

ado dos tipos de casas para estos lotes: colonial y estilo ranchero. Una casa colonial requiere $30,000 de capital y produce una utilidad de $4000 cuando se venda. Una casa estilo ranchero requiere $40,000 de capital y da una utilidad de $8000. Si la contratista tiene $3.6 millones de capital a la mano, ¿cuántas casas de cada tipo debe construir para obtener máxima utilidad? ¿Quedarán vacíos algunos de los lotes?

Answer:

número de rancho en casa= 90 homes

número de coloniales = 0

Step-by-step explanation:

Deje que el número del colonial sea x

Deje que el número de rancho sea y

Entonces;

30000 x + 40000 y = 3.6 × 10⁶ ---- (1)

x = \frac{3.6*10^6-4*10^4y}{3*10^4}

entonces beneficio P = 30000 x + 8000 y

P = 30000(\frac{3.6*10^6-4*10^4y}{3*10^4})+8000 \ y

\frac{dP}{dy} = \frac{-4*10^4}{3*10}+8000

Para obtener el máximo beneficio; El número de casas de rancho debe ser lo más alto posible:

y = \frac{3.6*10^6}{4*10^4}

número de rancho en casa= 90 homes

número de coloniales = 0

Fred flips a coin, spins the spinner, and rolls a standard number cube. Find the probability that the coin will show tails, the
Inessa05 [86]

Answer:

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is \frac{4}{3}  

Step-by-step explanation:

Given : Fred flips a coin, spins the spinner, and rolls a standard number cube.

To find : The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three ?

Solution :

First we find probability one by one,

1) Flips a coin - Head, Tail

Total number of outcome = 2

Favorable outcome (getting a tail) = 1

Probability that the coin will show tails is P(T)=\frac{1}{2}

2) Spins the spinner - yellow, green, blue

Total number of outcome = 3

Favorable outcome (land on yellow or green) = 2

Probability that the spinner will land on yellow or green P(S)=\frac{2}{3}

3) Rolls a standard number cube - 1,2,3,4,5,6

Total number of outcome = 6

Favorable outcome (show a three) = 1

Probability that the cube will show a three P(C)=\frac{1}{6}

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is

P=P(T)+P(S)+P(C)

P=\frac{1}{2}+\frac{2}{3}+\frac{1}{6}

P=\frac{3+4+1}{6}

P=\frac{8}{6}

P=\frac{4}{3}

Therefore, The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is \frac{4}{3}

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?
lidiya [134]

Answer:

The total fluid you have to drink is 10  7/10  =  10.7  cups.

Step-by-step explanation:

The daily requirement  of water =  8 2/4 cups

Now, 8 \frac{2}{4}  = 8+  \frac{2}{4}  = 8+ 0.5 = 8.5

or, the daily water requirement = 8.5 cups

The daily requirement  of milk =  2 1/5 cups

Now, 2 \frac{1}{5}  = 2+  \frac{1}{5}  = 2+ 0.2 = 2.2

or, the daily milk requirement = 2.2 cups

So, The total fluid needed  = Cups of  (Water + Milk) needed

                                              =  8.5 cups + 2.2 cups

                                              = 10.7 cups

Also, 10.7 = 10 + 0.7 = 10 + \frac{7}{10}  = 10\frac{7}{10}

Hence, the total fluid you have to drink is 10 7/10 cups.
