Lets x is the number of miles

Car Stars Auto Rental charges $35 a day plus $0.25 per mile = 0.25x + 35
Car Express Auto Rental charges $17 a day plus $0.40 per mile =0.40x + 17

0.25x + 35 = 0.40x + 17
0.25x -0.40x = 17 - 35
-0.15x = -18
x = -18 / -0.15
x = 120

answer: <span>D. 120 miles </span>

Answer:

d 120

Step-by-step explanation:

0.25x + 35 = 0.40x + 17

0.25x -0.40x = 17 - 35

-0.15x = -18

x = -18 / -0.15

Stels [109]

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1150$

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ $\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }$

On substituting the values, we get

⇒ $=\frac{1150}{\sqrt{500} }$

then,

⇒ $=P(-1.94$

⇒ $=P(Z$

On using the table of P, we get

⇒ $=0.9738 - 0.0262$

⇒ $=0.9476$

Kaitlyn tony and juan served a total of 71 orders Monday at the school cafeteria. Toney served 9 fewer orders than kaitlin. Juan

morpeh [17]

Answer:

<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Total of orders server at the school cafeteria by Kaitlin, Tony and Juan = 71

Tony served 9 orders fewer than Kaitlin

Juan served 2 times as many orders as Kaitlin

2. How many orders did each one serve?

For answering this question, we should prepare and write down our equation this way:

x = Number of orders served by Kaitlin

2x = Number of order served by Juan ( 2 times as many orders as Kaitlin)

x - 9 = Number of order served by Tony (9 orders fewer than Kaitlin)

x + 2x + x - 9 = 71

4x = 71 + 9

4x = 80

x = 80/4 = 20

x = 20 ⇒ 2x = 40 ⇒ x - 9 = 11

<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>

Remark
This question likely should be done before the other one. What you are trying to do is give C a value. So you need to remember that C is always part of an indefinite integral.

y = $\int (cos(x) + sin(x) ) \, dx = \int{cos(x) \,dx + \int sin(x) \,dx$
y = sin(x) - cos(x) + C
y(π) = sin(π) - cos(π) + C = 0
y(π) = 0 -(-1) + C = 0
y(π) = 1 + C = 0
C = - 1

y = sin(x) - cos(x) - 1 <<<<< Answer

Problem Two
Remember that $y = \int\ { \frac{1}{x} } \, dx = ln(|x|) + C$
y( - e^3 ) = ln(|x|) + C = 0
y(-e^3) = ln(|-e^3|) + C = 0
y(-e^3) = 3 + C = 0
3 + C = 0
C = - 3

y = ln(|x|) - 3 <<<< Answer

Answer: 7

Add up the values to get 4+10 = 14

Then divide that result over 2 to get 14/2 = 7

This is using the midpoint formula.
