Answer:
8%
Step-by-step explanation:
Divide ( 32.40 / 30 ). This outputs the answer 1.08, or 108%. This means that the outcome is 108% of the original, or 8% greater.
That comes to 225.65 / 6.25

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:
3rd Option
Step-by-step explanation:
Which equation is the inverse of y = 7x2 – 10?
y = StartFraction plus-or-minus StartRoot x + 10 EndRoot Over 7 EndFraction
y = plus-or-minus StartRoot StartFraction x + 10 Over 7 EndFraction EndRoot
x = plus-or-minus StartRoot StartFraction x Over 7 EndFraction + 10 EndRoot
y = StartFraction plus-or-minus StartRoot x EndRoot Over 7 EndFraction plus-or-minus StartFraction StartRoot 10 EndRoot Over 7 EndFraction
