joja [24]

Answer:

Becky put 224 stamps on the stamp collection book

Step-by-step explanation:

We know that Becky put 14 stamps on each page and she did it on 16 pages.

To find out how many stamps were in the entire stamp collection book, we have to multiply the number of stamps on each page by the number of pages

14 * 16 = 224

A 25-foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building. If the top of the ladder sl

algol [13]

Answer:

As per the statement:

A 25-foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building.

⇒Length of the ladder against a building = 25 foot

and Length of the bottom of the ladder from the building= 7 feet.

You had Before the slip.

Let x be the height of the building where ladder hits the building

By Pythagoras theorem:

$\text{Hypotenuse side}^2=\text{Perpendicular}^2+\text{Base}^2$

Here, Perpendicular side = Height of the building = x , Base = Length of the bottom of the ladder from the building = 7 foot and Hypotenuse side = 25 foot

Substitute the value to solve for x;

$25^2=x^2+7^2$

$625=x^2+49$

$x^2 = 625-49 = 576$

$x = \sqrt{576} = 24$ foot.

⇒Height of the building = 24 foot

Now, if the ladder slips down 4 feet.

You had after slip

⇒Now, the height of the building becomes = 24-4 = 20 foot.

Let y be the distance from the building wall

then by Pythagoras theorem;

$y^2+20^2 = 25^2$

$y^2+400 =625$

$y^2 = 625-400 = 225$

$y=\sqrt{225} = 15$ foot.

We have to find how many feet will the bottom slide out.

Since, Originally the distance of the bottom from the building = 7 foot

And now, the distance is = 15 foot.

The bottom slide out will be = 15 - 7 =8 foot

Therefore, 8 feet will the bottom slide out

What is the product of -2/7 and -3/6

Andrew [12]

Hey!

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

Product means multiplication.

-2/7 * -3/6 = -6/42 = -1/7

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

Hence, the answer is $\Large\boxed{\mathsf{-1/7}}$
