A Tourist Information Center is between a Bus Station and a Train Station. When mapped on a grid, the Tourist Information Center is located at (11,11) and the Bus Station is located at (-3,3).

Answers

Answer 1

Answer:

(25,19)

Step-by-step explanation:

We are to find the location of the train station.

Using the formula for calculating midpoint given as:

M(X,Y) = [(x1+x2)/2, (y1+y2)/2]

X = x1+x2/2

Y = y1+y2/2

Given

M(X,Y) = (11,11)

Bus station (x1, y1) = (-3,3)

Substituting the given parameters into the formula.

11 = -3+x2/2

Cross multiply

11×2 = -3+x2

22 = -3+x2

x2 = 22+3

x2 = 25

Similarly

Y = y1+y2/2

11 = 3+y2/2

Cross multiply

11×2 = 3+y2

22 = 3+y2

y2 = 22-3

y2 = 19

Hence the location of the train station is at (25,19)

Plug in method?I am trying to use the plug in method and I did that but then was not sure how to solve the problem after plugging in numbers.

Answers

Well, the picture is cut off below choice-C, and the whole thing is
very confusing to try and read because of trying to do all of your
work in the holes and spaces around the choices. So I'm just
going to ignore all of that, take the question, and work with it.

-- price of one book = k
-- total income if 1 book is sold = 1 · k
-- total income if 2 books are sold = 2 · k
-- total income if 100 books are sold = 100 · k

-- number of books for sale = 2b
-- total income if they're all sold = 2b · k
-- actual number that were sold = (2b - y)
-- actual total income = (2b - y) · k

You don't start with plugging in numbers. This is just testing whether you can find the right equation to plug numbers into.

the equation would be k(2b-y): he has 2b books, they sell for k each--> k*2b, but y books did not sell for k, so it's now k(2b-y)

the answer is A but I hope you understand the process now.

A bag has 90 fruits in it there are 9 times as many oranges as there are apples.So the bag has how many apples in it?

Answers

-- IF all 90 pieces in the bag are oranges or apples,
THEN there are 9 apples and 81 oranges.

-- You didn't specify that, so it's possible that there could be
2 apples, 18 oranges, and 70 kumquats or sabra pears.
