Answer:
13% chance
Step-by-step explanation:
Area of backyard = length * width
A = 30 ft * 20 ft
A = 600 
Area of bathtub = π 
A = π *
A = 78.54 
Probability of arrow landing in tub can be found by dividing Area of the bathtub by the area of the backyard, and then multiplying by 100 for a percentage
Prob. = 78.54/600
Prob. = 0.13
Prob. = 0.13 * 100
Prob. = 13%
Answer:
78.5 %
Step-by-step explanation:
the probability = π(2)² / (4×4) ×100%
= 4π /16 × 100%
= π/4 ×100%
= (π×25)%
= 3.14 × 25 %
= 78.5 %
Answer:
9.286
Step-by-step explanation:
I'm not guaranteeing this answer. If this is correctly written without any indication of how to deal with x, then here is as much as you can do.
850-53x m= 720-39x m Subtract 720 from both sides.
850 - 720 - 53x = 720 - 720 - 39xm Combine
- 53xm + 130 = - 39xm Add 53x
-53x+53xm + 130 = -39x + 53xm Combine
130 = 14xm Divide by 14
xm = 130/14
xm = 9.28
===============================
You can use the same steps above. I'm abbreviating the steps because they are the same.
I'm sure there is more to the problem, but I can't imagine what it is. If you have additional directions, put it under this answer. I will get it as a comment.
850-53m= 720-39m
850 - 720 - 53m = - 39m
130 - 53m = - 39m
130 = -39m + 53m
130 = 14m
130/14 = m
m =9.286
