The titanic had about half as many plates as they did pieces of silverware .About how many plates did they have ?
Korvikt [17]

Answer:

The answer is below

Step-by-step explanation:

1) Since the titanic was scheduled to reach on April 17 after leaving on April 10, this means that 7 days was spent on the voyage. The total amount of meat available was 75000 pounds, hence:

number of meat per day = total amount of meat / number of days = 75000 / 7 = 10714 pounds per day.

2) Total number of silverware is 44000. Hence:

Total plates = half of total silverware = 44000/2 = 22000

3) There are 3000 potatoes in a ton, and a total of 40 tons was available on the titanic. Hence:

Total number of potatoes = 40 tons * 3000 potatoes per ton = 120000 potatoes

Para el diseño de un tanque de tratamiento de agua se determina que su centro está ubicado en la posición (0;14) metros y está r
Andreas93 [3]

Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

x^{2} +y^{2} -28y + 180= 0

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

x^{2} +y^{2} -28y + 196 = -180 +196

Entonces obtenemos

x^{2} + (y-16)^{2} = 16

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

svlad2 [7]

Answer:    The ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.

Step-by-step explanation: Given that the manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.

Then, the ratio value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.

Given that the manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.

Then, the ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.

Given that the manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.

Then, the ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.
