Answer:
242
Step-by-step explanation:
Here, we want to calculate t15 + t25
Mathematically, nth term is
a + (n-1)d
here, a = 26 and d = 31-26 = 5
t15 = 26 + (15-1)5
t15 = 26 + 70
t15 = 96
t25 = 26 + (25-1)5
t25 = 26 + 120
t25 = 146
t15 + t25 = 96 + 146 = 242
It is 10m/s.The 10-second barrier is the physical and psychological barrier of completing the 100 metres sprint in under ten seconds
F, G, J, L, N, P, Q, R, Z... I'm pretty sure that these are right. If they aren't then I apologize, I am not 100% sure though. Hope that this helped!
90°
This is because of the fact that a square always has four 90° angles
Answer is numbers 10, 30, 70, 90
The 4 numbers must be different and added up and divided by 4 must equal 50.
Four such numbers are 10, 30, 70, 90
We all know that Average = Sum / total of numbers in sum
Addition of these different 4 numbers = 200.
Average = 200 / 4 = 50, the required average.
Problem solved!
