Solution
6blue marbles
5 red marbles
4 white marbles
Part A
Formula
Not white means it blue or 5 = 11
Part B
Answer:
(-5,2) (-7,0)
Step-by-step explanation:
15 - 4t = 3
-15 -15
-4t = -12
-4t/-4 = -12/-4
t = 3
Answer:
improper because the numerator cant be a larger number than the denominator
Answer: 644,800
Step-by-step explanation:
This can also be solved using the terms of Arithmetic Progressions.
Let the 13 years be number of terms of the sequences (n)
Therefore ;
T₁₃ = a + ( n - 1 )d , where a = 310,000 and d = 9% of 310,000
9% of 310,000 = 9/100 x 310,000
= 27,900
so the common difference (d)
d = 27,900
Now substitute for the values in the formula above and calculate
T₁₃ = 310,000 + ( 13 - 1 ) x 27,900
= 310,000 + 12 x 27,900
= 310,000 + 334,800
= 644,800.
The population after 13 years = 644,800.
