<h2>Answer:</h2><h3>Part 1:</h3>
Given:
Total shelves: 6
Books per shelve: 72
Total books = ?
Solution:
Total books: 6 * 72 = 432
Total books = 432
<h3>Part 2:</h3>
Given:
Fiction books = 1/3 of total books
Solution:
Nonfiction books = Total books - 1/3 of total books
= 432 - 1/3 * 432
= 432 - 166 = 266
Non- fiction books = 266
Answer:
-78
Step-by-step explanation:
substitute x as 10
so then you get
(-8) (10) + 2
then simplify
-80+2 = -78
Answer:
T.A. = 144 + 36√3 units²
Step-by-step explanation:
∵ The total surface area of the pyramid = the sum of the area of
the four faces (one base and 3 side faces)
∵ The 3 side faces have the same dimensions 12 , 10 , 10
∴ the area of the 3 faces = 3 × 1/2 × 12 × h
∵ The height of each triangle is ⊥ to its base
∵ The triangle are isosceles
∴ The height bisects the base
∴ h² = 10² - 6² = 64
∴ h = √64 = 8
∴ The area of the 3 triangles = 3 × 1/2 × 12 × 8 = 144 units²
∵ The base is equilateral Δ with side length 12
∵ Area equilateral triangle = 1/4 × s² × √3
∴ The area of the base = 1/4 × (12)² × √3 = 36√3 units²
∴ T.A. = 144 + 36√3 units²
I'm assuming you mean which one is written properly? It would be either 3 x 10^4 or 6 x 10^4.
Hope it helps!
