718-119x+719 for x =0<br> please simplify and find the value

iragen [17]

The answer would be 1437 due to the zero property. Therefore you only add the other two numbers.

The Loft Theater has a center seating section with 3c + 8 rows and 4c-1 seats in each row. Write an expression for the total num

yulyashka [42]

If there are n rows

And if each row has m seats.

Then the total number of seats shall be n × m.

Here

Number of rows = (c+8)

And number of seats in each row = (4c-1)

Using the concept

Total number of seats

= (c+8)(4c-1)

FOILing or Distributing we get

= c(4c) + c (-1) + 8(4c) +8 (-1)

= 4c² - c + 32 c -8

Combining like terms

=4c² +31c - 8

The expression for total number of seats = 4c² + 31c -8

The manager of a theater noted that for every 10 admission tickets sold, the theater sells 3 bags of popcorn at $2.25 each, 4 so

Shalnov [3]

Answer:

$1.475 is the average amount of snack sales per ticket sold.

Step-by-step explanation:

We are given the following in the question:

Number of popcorn bags sold = 3

Cost of a popcorn bag = $2.25

Total cost of popcorn bag = $2.25\times 3$ = $6.75

Number of soda sold = 4

Cost of a soda = $1.50

Total cost of soda = $1.50\times 4$ = $6.00

Number of candy bars sold = 2

Cost of a candy bar = $1.00

Total cost of candy bars = $1.00\times 2$ = $2.00

Total sales =

Total cost of popcorn + Total cost of soda + Total cost of candy bar

$= 6.75 + 6 + 2\\=\$14.75$

$\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

Average amount of snack sales per ticket sold =

$\dfrac{\text{Total sales}}{\text{Number of tickets}} = \dfrac{14.75}{10} = 1.475$

Thus, $1.475 is the average amount of snack sales per ticket sold.

The function is used to convert temperature from Celsius (C) to Fahrenheit (F). The function C(K) = K − 273.15 is used to conver

jeka94

Answer:

The correct function for converting temperature from Kelvin to Fahrenheit is $F(K) = \frac{9(K - 273.15)}{5} + 32$

Step-by-step explanation:

Kelvin to Celsius function:

The function to convert a temperature from degrees Kelvin to degrees Celsius is given by:

$C(K) = K - 273.15$

Celsius to Fahrenheit function:

The function to convert a temperature from degrees Celsius to degrees Fahrenheit is given by:

$F(C) = \frac{9C}{5} + 32$

Which is the correct function for converting temperature from Kelvin to Fahrenheit?

In the equation to find F(C), we use C = C(K). So

$F(C) = \frac{9C}{5} + 32$

$F(C(K)) = \frac{9(K - 273.15)}{5} + 32$

$F(K) = \frac{9(K - 273.15)}{5} + 32$

The correct function for converting temperature from Kelvin to Fahrenheit is $F(K) = \frac{9(K - 273.15)}{5} + 32$
