1/3+2/9=1/6x-4/6
3/9+2/9=1/6x-4/6
5/9=1/9x-4/6
5=x-6
x=11
You can use c^2 = a^2 + b^2 to solve for the length of the other leg. Just substitute the values to the variable then transpose to get the value of the missing variable.
Given: a = 13; c = 21
Required: b - other leg
Solution:
c^2 = a^2 + b^2
21^2 = 13^2 + b^2
441 = 169 + b^2
b^2 = 272

Answer:882
Step-by-step explanation:5 percent of 840 is 42 so 840 plus 42
Answer: 30%
Step-by-step explanation:
Total number of people involved in the tournament= 50
Number of people chosen to play rugby= 35
Number of people chosen to play football= 15
To get the percentage of people that are chosen to play football, we divide the number of people chosen to play football by the total number of people chosen for the tournament and then multiply the answer by 100. This will be:
= 15/50 × 100
= 0.3 × 100
= 30%
The percentage of people chosen to play football is 30%.
