Answer:

The ladder is 5.20 feet tall on the side of the building

Step-by-step explanation:

Here, we simply want to calculate the height the ladder is from the base of the building

To get this, we need a pictorial representation of what we have here.

From what we have here, we have a right-angled triangle with a hypotenuse of 10 foot and a base of 3 feet

We apply Pythagoras’ theorem to get how far is the tip of the ladder from the base of building

Pythagoras’ stated that the square of the hypotenuse equals the sum of the squares of the two other sides

In this case, let the height be x

So;

x^2 + 3^2 = 6^2

x^2 = 6^2 - 3^2

x^2 = 36 - 9

x^2 = 27

x = √27

x = 5.196 feet

which to two decimal places is 5.20 feet

Pam typed 2.5 pages in 15 minutes. At that rate, how many minutes will it take her to type 23 pages?
NeX [460]
In the given question, it is already mentioned that Pam takes 15 minutes to type 2.5 pages. this information should be used as the main information for reaching the desired answer.
Pam typed 2.5 pages in = 15 minutes
Then time taken by Pam to type 23 pages = (15/2.5) * 23
                                                                     = 345/2.5
                                                                     = 3450/25
                                                                    = 138
So Pam will take 138 minutes to type 23 pages
