51.54 rounded to the nearest whole number equals to 52.
Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, we have that:
- The rate in Brazil is of
.
- The rate in the United States is of
.
Hence, the rate between the consumption in Brazil and in the United States is given by:
Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

Answer:
8
Step-by-step explanation:
The answer is 8 because the budget for the school is 200 and they bought 7 paper back books and paperback books cost 10$ each so we multiply 7 and 10 together and get 70 the we subtract 200 by 70 and get 130. Then we divide 130 by 15 and get 8.66666 and so we can by 8 books. Whith 10$ left over.
Answer:
The number of non-congruent triangles that can be formed from the vertices of a cube are 3 triangles
Step-by-step explanation:
The number of non congruent triangles that can be formed by connecting 3 of thee vertices of the cube is found as follows;
The available different lengths of segments joining two vertices of a cube of side length s = 2 are;
2, 2·√2, and 2·√3
Therefore, since there are only three different side lengths we have the possible triangle dimensions given as follows
Distinct triangle one = 2, 2, 2·√2
Distinct triangle two = 2·√2, 2·√2, 2·√2
Distinct triangle three = 2, 2·√3, 2·√2
Therefore, there are ₃C₃ = 3 ways of forming three non-congruent triangles from the vertices of a cube.
