Galvin bought 3/5 as many non-fiction books as fiction books from a book fair. He read 6 non-fiction books and 13 fiction books. He then had 3/4 as many non-fiction books left to read as fiction books. How many books did Galvin buy altogether?

Answers

Answer:

Let total non-fiction books = 3x

And total fiction books = 5x

After reading 6 non-fiction books, remaining non-fiction books = 3x-6

After reading 13 fiction books, total fiction books remaining fiction books = 5x-13

(3x-6)/(5x-13) = 3/4

Solving for x, we get x = 5

So total non-fiction books = 15 and fiction books=25

So total number of books bought = 40

calculate the diameter of the circle

Answers

Answer:

2.64cm

Step-by-step explanation:

A = π r^2

5.5 = π r^2

1.75 = r^2

r = 1.32

Diameter is then 2(1.32) = 2.64

Answer:

Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?

Answers

Answer:

27 years approx

Step-by-step explanation:

Given data

Principal P= $ 3,000

Final amount A= $ 7000

Rate r= 5%

The simple interest expression is

A=P(1+rt)

substitute and solve for t

7000=3000(1+0.05t)

7000=3000+150r

7000-3000=150r

4000=150t

t= 4000/150

t= 26.66

Hence, the time is 27 years approx
