Mr.Brown has 110 fiction books and 90 non-fiction books on his shelf. what percent of her library is non fiction?
Vanyuwa [196]

Answer:

45%

Step-by-step explanation:

Given

Number of fiction books = 110

Number of non fiction books = 90

Total number of books = 110 + 90 = 200

% of non fiction books

= number of non fiction books divided by the total number of books multiplied by 100%

That’s

90/200 x 100%

0.45 x 100%

45%

45% of her library is nonfiction

Nth term sequences, please may I get some help. 15 p.
Dovator [93]

Answer:

(n+2)^2+6

Step-by-step explanation:

Pattern 1 consists of

3+3\times 3+3 small squares (here n = 1 and 3\times 3=(1+2)\times (1+2)).

Pattern 2 consists of

3+4\times 4+3 small squares (here n = 2 and 4\times 4=(2+2)\times (2+2)).

Pattern 3 consists of

3+5\times 5+3 small squares (here n = 3 and 5\times 5=(3+2)\times (3+2)).

Thus, pattern n consists of

3+(n+2)\times (n+2)+3=6+(n+2)^2 small squares.
