So we know that Lorenzo has 12 cookies right.
So now we have to find out how many cookies Celine has because there was no number of cookies she received.
So Celine now has 12 cookies.
So we now that Petra would have "12".
Because it didn't say that Celine or Lorenzo ate them, did it?!
I hope this helped!:)

A ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the len
masha68 [24]

Answer:

25\text{ feet}

Step-by-step explanation:

The ladder, ground, and building form a right triangle where the vertical distance between the top of the ladder and the bottom of the ground is one leg, the horizontal distance between the bottom of the ladder and the building is another leg, and the length of the ladder is the hypotenuse.

For any right triangle, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared (a^2+b^2=c^2), where c is the hypotenuse.

Let the length of the ladder be \ell (hypotenuse of right triangle). The distance between the top of the ladder and the ground (vertical distance) can be represented as \ell -1.

From the Pythagorean Theorem, we then have:

7^2+(\ell-1)^2=\ell^2

Expand using (a-b)^2=a^2-2ab+b^2:

49+\ell^2-2\ell+1=\ell^2

Subtract \ell from both sides and add 2\ell to both sides:

49+1=2\ell

Combine like terms:

50=2\ell, \\2\ell =50

Divide both sides by 2:

\ell=\frac{50}{2}=\boxed{25\text{ feet}}

Therefore, the length of the ladder is 25 feet.
