Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
Upon simplifying we will get,
Therefore, Hannah donated books.

Answer:
The distance of the bottom of the ladder be from the bottom of the building is = 15 feet
Step-by-step explanation:
Given:
Length of the ladder =17 ft
Height of the building = 8 ft
To find the length between the bottom of the ladder and the bottom of the building.
Solution:
On drawing out the situation, we find out that a right triangle is formed with the ladder being the hypotenuse and the building being a leg of the right triangle.
<em>We need to find the length of the other leg of the triangle which is the distance from the bottom of the ladder to the bottom of the building.</em>
Applying Pythagorean theorem:
Plugging in values in feet from the given data.
Simplifying.
Subtracting both sides by 64.
Taking square root both sides.
∴
Thus, distance of the bottom of the ladder be from the bottom of the building is = 15 feet
