The two balls take 5 seconds to meet together
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
Ball A.
Distance travel after n seconds = 50, 48, 46, 44, 42, 40,,,,,
Sum of nth term = n/2[100 + (n - 1)2 ]
Ball B.
Distance travel after t seconds = 30, 28, 26, 24, 22, 20,,,,,
Sum of nth term = n/2 [60 + (n - 1)2]
Now,
n/2 [100 + (n - 1)2] + n/2 [60 + (n - 1)2] = 420
50n + 2n - 2 + 30n + 2n - 2 = 420
80n + 4n - 4 = 410
84n = 414
n = 414/84
n = 5
Thus,
The ball takes 5 seconds to meet.

Answer: 17
Step-by-step explanation:The other side is the same length. So its 17 :)
Answer:
18.3 = The third side
Step-by-step explanation:
Using Pythagorean Theorem; since the triangle is a right angled triangle.
Pythagorean Theorem states: A² + B² = C² (Where C is the hypotenuse, the line on the triangle opposite to the labeled right angle of the triangle, A and B would be the other 2 sides).
=> A² + B² = C²
=> 17² + B² = 25²
=> 289 + B² = 625
=> B² = 625 - 289
=> B² = 336
=> [tex]\sqrt{B^2}[/tex] = [tex]\sqrt{336}[/tex]
=> B = [tex]\sqrt{336}[/tex]
=> B = 18.3

Answer:
C: 139
Step-by-step explanation:
180 - 29 - 12 = 139.
Every triangle has a total of 180 degrees, therefore, subtract the degrees you do have, and find the missing one. Quadrilaterals have a total of 360 degrees and pentagons have 540 degrees.

Answer:
1) 7/8
2) 0. 9
3) 88%
Step-by-step explanation:
total CDs = 2 + 9 +5 = 16
probability of Comedy is 2 out of the total 16
= 2/16
probability of not picking one would be 1 - 2/16 = 14/16 = 7/8
7 divided by 8 = 0.875 which rounds to 0.9
0.875 x 100 gives the percentage of 87.5% which rounds to 88%

Answer:
The slope of the trend line is 19.286 thousand dollars. This is important because it shows that the sales of this store is increasing which intern increases profits which is important for the long term viability of this store.They y-intercept is 53.571 thousand dollars. This number represents the profits of the store in 2010 and it serves as benchmark for future years. In fifty years, we assuming that the trend continues, it will be 19.286*50+53.571 = 1017.871 thousand dollars. However, this is not appropriate because a lot can change in 50 years which can have a profound impact on the future profits.
