Find the point that lies 1/8 of the way on the line A to B, given that A is at -14 and B is at 10.

Answers

Answer:

-11

Step-by-step explanation:

Find the distance from point A to point B.

|-14 - 10| = |-24| = 24

Now find 1/8 of the distance from A to B.

1/8 * 24 = 24/8 = 3

Add 3 to the coordinate of point A.

-14 + 3 = -11

Answer: -11

Answer:

the point that lies at 1/8 from A = -11

Step-by-step explanation:

       1/8      

        v

A --------------------|---------------B

-14                      0                10

14 + 10 = 24

1/8 x 24 = 3

distance from point A = 3

therefore,

the point that lies at 1/8 from A = -11

The ford escape hybrid made its debut in 2004 as the first SUV hybrid. During 2007, 21,386 of these SUVs were sold, an increase I of approximately 11% over previous year. Approximately how many ford escape hybrids were sold in 2006?

Answers

x is cars sold in 2006
x*1.11=21386, solve for x

Why is the sum of a rational number and its opposite always equal to 0

Answers

because its like saying what's 4-4=0. -4 and 4 are the same distance away from zero, so if you subtract them (or add them), it'll always end up to be zero

Which shows a correct order to solve this story problem? Allie, Serena, and Mikala went to the movies. They spent a total of $30.90 for their movie tickets and $8.50 each for popcorn and drinks. The total tax for the tickets and snacks was $3.96. They split all the costs evenly. How much did each girl pay? A. Step 1: Add $30.90 and $8.50. Step 2: Add the tax to that amount. Step 3: Divide by 3. B. Step 1: Calculate the price of 1 ticket. Step 2: Divide the total tax by 3. Step 3: Add the amounts from Steps 1 and 2 to $8.50. C. Step 1: Add the price of the tickets and the amount spent on food. Step 2: Add the amount of the tax. Step 3: Divide that total by 2.

Answers

30.90 + 8.50 + 3.96 = 43.36 (total cost)

If they are all splitting it evenly then divide by total ammount of people

43.36 / 3 = 14.45 each

The answer is A

Jennifer is going on a hike to the top of a mountain. It will take 3 hours and 55 minutes to hike up the mountain and 1 hour and 10 minutes to hike back down. If Jennifer wants to finish the hike by 3:45 P.M., what is the latest time she can start the hike up the mountain? Include A.M. or P.M. in your answer (for example, 11:58 A.M.).

Answers

Answer: 10:40 AM

====================================================

Explanation:

Add the minutes for now

55 minutes + 10 minutes = 65 minutes = 60 minutes + 5 minutes = 1 hour, 5 minutes

The minute portions add to 1 hour, 5 minutes. The hour portions add to 3+1 = 4.

Add on the "1 hour, 5 minute" portion and we get 5 hours, 5 minutes

This is the total duration of the round trip hike. Keep in mind that this does not include any time spent with Jennifer resting at the top of the mountain. This time duration assumes that once she gets to the top, she pretty much starts the hike back down the mountain.

----------------------------

Now convert 3:45 PM to military time. We add 12 hours to get 15:45

Subtract off 5 minutes to get 15:40

Then subtract off 5 hours to get 10:40, which converts back to 12-hour time notation to be 10:40 AM
