Answer:
10
Step-by-step explanation:
Given that Sasha has won 0 games in the 40 games she has played.
Let she needs to win x game in a row, so
Total game she played = 40 + x
The number of the game she won is x, which is 20% of the total game she played, so
x = 20% of (40+x)
Hence, she needs to win 10 games in a row.
Answer: A=100(12)t5.27
Step-by-step explanation:
Assume / and ^ got lost from eqns.
A(t) = initial × (1/2)^(t/halflife)
So initial = 100, halflife = 5.27,
A=100(12)t5.27 means A=100(1/2)^(t/5.27)
so that A is 50 when t is 5.27

Answer:
see explanation
Step-by-step explanation:
(a)
Note the squared value in column 3 which is the square of 1 more than the row number, that is
row 2 → (2 + 1)² →3²
row 3 → (3 + 1)² → 4²
Find the square root of 676 = 26 → (25 + 1)² = 26²
Hence the row number is 25
(b)
The pattern in column 1 is [ row number × (row number + 2 ) + 1 ]
row number is n then n(n + 2) + 1 = n² + 2n + 1
