Answer:

11.25 pesos cada uno

Step-by-step explanation:

En esta pregunta el precio al que contrataron el autobus es un precio fijo, asi que tenemos que calcular este precio fijo primero. Esto lo hacemos multiplicando los 30 alumnos por los 15 pesos que tienen que pagar cada uno...

30 * 15 = 450 pesos

Vemos que el autobus tiene un precio fijo de 450 pesos, ahora podemos dividir este precio fijo por los 40 alumnos que fueron en el viaje para calcular cuanto tiene que pagar cada uno

450 / 40 = 11.25

Ahora podemos ver que cada uno de los 40 alumnos tendran que pagar 11.25 pesos cada uno

The initial cost to drill a well is $210000. the daily rate to operate the well is $500. The current selling price is $65 per ba
SVETLANKA909090 [29]

Hi there!

There is an initial cost of $210,000 (which you're just going to pay once)

Then it costs $500 per day to operate.

The number of days is represented by "x".


Your equation in function notation should look like this :

f(x) = 500x + 210,000


There you go! I really hope this helped, if there's anything just let me know! :)

The picture frame has a perimeter of 100 inches. The width is 22 inches. Calculate the missing length. Use that answer to find t
ivanzaharov [21]

Answer:

39 inches.

858 inches²

Step-by-step explanation:

Length:- (if length = x)

2 ( 11 + x ) = 100

22 + 2x = 100

2x = 100 - 22

2x = 78

x = 78 ÷ 2

x = 39 inches

Area:-

Area = l × b

= 39 × 22

= 858 inches²

What is the sum of the sequence 152,138,124, ... if there are 24 terms?
N76 [4]

Answer: -216

Step-by-step explanation:

To solve the exercise you must use the formula shown below:

Sn=\frac{(a_1+a_n)n}{2}

Where:

a_1=152\\a_n=a_{24}

You should find  a_{24}

The formula to find it is:

a_n=a_1+(n-1)d

Where d is the difference between two consecutive terms.

d=138-152=-14

Then:

a_{24}=152+(24-1)(14)=-170

Substitute it into the first formula. Therefore, you obtain:

S_{24}=\frac{(152-170)(24)}{2}=-216
