If you place a 89-foot ladder against the top of a 80-foot building, how many feet will

Nuetrik [128]

Answer:

$\large \boxed{\text{39 ft}}$

Step-by-step explanation:

Let x be the distance from the foot of the ladder to the base of the building.

We have a right triangle, so we can use Pythagoras' Theorem.

$\begin{array}{rcl}80^{2} + x^{2}& = & 89^{2} \\6400+ x^{2} & = & 7921\\x^{2} & = & 1521\\x & = & \sqrt{1521}\\& = &\mathbf{39}\\\end{array}\\\text{The foot of the ladder will be $\large \boxed{\textbf{39 ft}}$ from the base of the building,}$

natali 33 [55]

Answer:

Volume, $V=175\ cm^3$

Step-by-step explanation:

We have,

Height of each tin is 5 cm

The area of the lid of the tin is 35 square centimeters.

It is required to find the volume of the cat food that the tin contains. Volume of the box is also given by the product of area and height such that,

$V=A\times h\\\\V=35\times 5\\\\V=175\ cm^3$

So, the volume of the cat food that the tin contains is $175\ cm^3$ .
