Let's create a variable to represent the size of Ruben's book collection prior to his buying the new books.
B = number of books in Ruben's collection before buying new ones
So, we know that when he bought 6 books, this increased his collection by 12%.
12% of his book collection would be represented by 0.12B. Therefore, we know that:
0.12B = 6
Divide both sides by 0.12, to get to B = 50.
However, you are being asked how many books does he have now. B represents the number of books he had before. Therefore you want to add back the 6 books he just bought.
The answer is 50 + 6 = 56
We know that
[scale]=[doll house]/[<span>real house]
[scale]=12 in/3 ft
</span><span>The living room in stacy's house is 18 feet by 12 feet
</span>so
for 18 ft
[doll house]=[scale]*[real house]-----> (12/3)*18--------> 72 in
for 12 ft
[doll house]=[scale]*[real house]-----> (12/3)*12--------> 48 in
The living room in doll house is 72 in by 48 in
The living room area in doll house is (72*48)-----> 3456 in²
<span>Tom will need for the living room in Stacy's doll house 3456 in</span>² <span>of carpeting
the answer is </span>3456 in² of carpeting
Answer:3.55 liters of paint are in each container
Step-by-step explanation:
Total amount of paint ( purple paint ) =Amount of red paint + Blue paint
= 6.42 Liters + 6.87 Liters
=13.29Liters
Amount of paint in the three containers = Total amount of paint ( purple paint ) - amount left over = 13.29- 2.64
=10.65Liters
Amount OF Paint in each container = Amount of paint in the three containers / 3
10.65/ 3
=3.55 liters
