A 29- m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 33 . Find the length
prohojiy [21]

Answer:

About 17.7 meters.

Step-by-step explanation:

This can be solved by imagining the triangle formed by the building and its shadow. The hypotenuse of the triangle, the distance from the tip of the building to the tip of the shadow, is 34 meters, and one of the legs is 29 meters.

Question 2 (1 point)
nikdorinn [45]

Answer: 24 hours - no; because depending on where you are on Earth, you have a  different amount of sunlight.

Step-by-step explanation:

The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.

People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

The sum of two numbers is 40 - 13. what are the integers.
Anni [7]
So. let's say the numbers are "a" and "b"

whatever they're, we know a + b = 56

let's say the larger one is "b", so 3 times the smaller is 3*a or 3a
now, 12 less than that, is 3a - 12

and the larger is that, so b = 3a - 12

so   \bf \begin{cases}
a+b=56\\
\boxed{b}=3a-12\\
----------\\
a+\boxed{3a-12}=56
\end{cases}

solve for "a", to see what the smaller one is

what's b? well, b = 56 - a
