Answer:
e = 6
Step-by-step explanation:
10e - 2e - 9 = 39
8e - 9 = 39
8e = 48
e = 6
CHECK:
10(6) - 2(6) - 9 = 39
60 - 12 - 9 = 39
39 = 39
Considering the area of the hole, it is found that there is a 4.9% probability of hitting a ball into the circular hole.
<h3>What is the area of a circle?</h3>
The area of a circle of radius r is given by:

In this problem, the hole has a diameter of 1 ft, hence it is radius is of r = 1 ft/2 = 0.5 ft, and it's area is given by:

Hence the probability is given by:
p = 0.7854/16 = 0.049 = 4.9%

145 pages because 145 would round up to 150 but anything below 145 would round to 140
Answer:
x = 6, ∠ B = 126°
Step-by-step explanation:
∠ A and ∠ B are alternate angles and congruent, so
8x + 78 = 2x + 114 ( subtract 2x from both sides )
6x + 78 = 114 ( subtract 78 from both sides )
6x = 36 ( divide both sides by 6 )
x = 6
Then
∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°
