Answer:
36
Step-by-step explanation:
18 × 2 = 36
Because 1/2 is half of 1 kg so multiply by 2 it makes 1 kg
The closest number of questions you can get right to get a 70% on our test is 20. Because to find a percentage you divide the number of questions to the number of questions you got right. If you get 20 correct out of 28 you got a 71%.

The distance d from port c to port a from the given ship movement is gotten as; 7.7 miles.
<h3>How to calculate bearing distance? </h3>
We are given;
Ferry travels east 3.5 miles from Port b.
Then it turns 75° south and travels for 6 miles till it gets to Port c
To get the distance d from port c to port a, we would make use of cosine rule which is;
c = √(a² + b² - 2ab*cos C)
Thus;
d = √(3.5² + 6² - 2(3.5 * 6)*cos 75))
d = 7.7 miles

the other number is 50 - p
Consider a numeric example
2 numbers sum to 5 , one of the numbers is 3 what is the other ?
Obviously 2 , that is 5 - 3 = 2 gives the number
In the same way the number here is p and 50 - p is the other number
Solving the system of equations shows that to make these equations true x=1 and y=0.5
