For this problem you must do Pythagorean theorem:
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51
Now you still must isolate b. The opposite of squaring is taking the square root so take the square root of both sides to cancel it from the left side:
b = 7.1414
b ≈ 7 ft
Hope this helped!
Answer:
3600
Step-by-step explanation:
Part A: There are 114 red marbles
Part B: There are 114 red marbles because if you multiply the ratio 19:1 times 6 you would get 114:6 (added together gives you 120)
