Juan is going to take a flight from Orlando, Florida, to Los Angeles, California.

andreyandreev [35.5K]

Answer:

The correct option is A:

A) Time of flight = 7 hours 5 minutes

Step-by-step explanation:

For eastern time zone, t = 12:00 pm

Then, pacific time zone , t = 9:00 am

Which means the pacific time lags 3 hours to eastern time

Time of departure = 9:15 am (eastern time)

TIme of arrival = 1:20 pm (pacific time)

Either convert both of them into eastarn time zone or pacific time zone to find the time of the flight. The answer for both will be the same.

Converting both in pacific time zone.

Time of arrival = 1:20 pm (pacific time)

Time of departure = (9:15 am (eastern time) - 3 hours) (pacific time)

Time of departure = 6:15am (pacific time)

Time of flight = Time of arrival - Time of departure

Time of flight = 1:20pm - 6:15am

Time of flight = 7 hours 5 minutes

The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2

vladimir2022 [97]

Answer:

$y-2 = -3(x-2)$

Step-by-step explanation:

Find the diagram to the question attached.

The standard equation of a line in point-slope form is expressed as:

$y-y_0 = m(x-x_0)$ where:

m is the slope of the line

$(x_0, y_0)$ is coordinate point on the line

First is to get the slope of the line.

$m = \frac{y_2-y_1}{x_2-x_1}$

If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)

$m = \frac{8-2}{0-2}\\m = \frac{6}{-2}\\m = -3$

Hence the slope is -3

Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)

$y-y_0 = m(x-x_0)\\y-2 = -3(x-2)$

Hence the equation of the line in point-slope form is $y-2 = -3(x-2)$

Three consecutive numbers have a sum of 366, what is the largest consecutive number of the three?

Llana [10]

Answer: 123

Step-by-step explanation: TO solve problems like this, you should assign a variable to the lowest number, lets just say n. From here, since we know the numbers are consecutive, we can see that the numbers are n, n+1, and n+2. Therefore:

n(first number) + (n+1)(second number) +(n+2) (3rd number) =366

>n+n+1+n+2=366

3n+3=366

3n=363

n=121

n+2=123
