Answer:
15:10
Step-by-step explanation:
consider the starting point: we have 3 bots and 2 girls. this gives a total count of 5 so we need to see how many lots of 5 will fit into 25. 5 lots of 5 gives 25 so we have 5 lots of the ratio 3:2 Method: 5 lots of 3:2: 5 x (3:2)=(5 x 3):(5 x 2)= 15:10
Answer:
12x =102-6
x=96/12
x=8 is the correct answer
Answer:
Approximately the number of men is 203 and number of women is 47.
Step-by-step explanation:
It is given that the United States Air Force has 19 women for every 81 men enlisted.
It means the ratio between men and women is 81:19.
Sum of ratio is

Therefore for each 100 people, there are 81 men and 19 women.
Total number of peoples is 250.

In 250 members the number of men is

The numbers of persons cannot be a fraction values or a decimal value, therefore the number of men is 203.
In 250 members the number of women is

Therefore approximately the number of men is 203 and number of women is 47.
The expert phase is different for different tasks. The calculator tries to calculate the sizes of three sides of the triangle from the entered data. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual parameters of the triangle. These are successively applied and combined, and the parameters of the triangle calculate. Calculator iterate until the triangle has calculated all three sides. For example, the appropriate height is calculated from the given area of the triangle and the corresponding side. From the known height and angle, the adjacent side, etc., can be calculated. They use knowledge, e.g., formulas (relations) Pythagorean theorem, Sine theorem, Cosine theorem, Heron's formula, solving equations and systems of equations.The second stage is the calculation of the properties of the triangle from the known lengths of its three sides.
