The number of hardback books that are on the bookshelf is 29 books.
- Let the total number of books be T.
- Let the number of hardback books be H.
- Let the number of paperback books be P.
<u>Given the following data:</u>
- Total number of books = 36 books
To determine the number of hardback books that are on the bookshelf:
Translating the word problem into an algebraic expression, we have;
The total number of books is:
The number of hardback books is 15 more than <u>twice</u> the number of paperback books:
Substituting the given parameters into the formula, we have;
P = 7 books
For number of hardback books:
H = 29 books

Answer:
0.395
Step-by-step explanation:
The computation of the probability that none of the three shoppers purchased electronics is shown below:
So, first we have to determine the number of shoppers without considering the purchase i.e
= Total number of shoppers - electronics
where,
Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics
= 18 + 25 + 40 + 12 - 25
= 95 - 25
= 70
Now the probability is
=
= 0.395
Answer:72 tiles
Step-by-step explanation:
16 x 18 = 288ft.2
2 x 2 = 4ft.2
288 divided by 4 = 72 tiles
Since 288 is the space of the wall, each tile has an area of 4 feet squared, so 288 divided by 4 would make it so they need 72 tiles.

Answer: a) extension = 0.12m, b) work done = 2.16 J
Step-by-step explanation: according to hooke's law, provided that elastic limit is kept constant force (f) is proportional to extension (e).
F = ke, k = F / e.
F1/e1 = F2/e2
F1 = 15 N, e1 = 0.10m, F2= 18 N, e2 =?
15/0.10 = 18/e2
e2 = 18 * 0.10/ 15
e2 = 1.8/15
e2 = 0.12m.
Work done at this extension = F2 * e2
Work done = 18 * 0.12 = 2.16 J
