Answer:
6th week.
Step-by-step explanation:
Each week he is selling 1/2 of the week before so
In the 3rd week he sells 400
- in the 4th week it will be 200
- in 5th week 100
- in 6th seek 50.
Answer: 6th week
Step-by-step explanation:the number of weeks is moving in a geometric proportion
Remember Tn = ar^n-1
Tn = 50, r = 800/1600= 1/2, a = 1600
So 50 = 1600 * 1/2^ n-1
50/1600 = 1/2^ n-1
1/32 = 1/2^ n-1
2^ -5 = 2^ -n+1
Equating powers
-5 = -n + 1
-n = -6
n = 6

Answer:
x = 11
Step-by-step explanation:
2x + 34 = 56
2x = 56 - 34
2x = 22
x = 22/2
x = 11
d/6+2/3=1/4(d-2)
d/6+2/3=d-2/4
2d+8=3(d-2)
2d+8=3d-6
8=3d-6-2d
8=d-6
8+6=d
14=d
d=14
Answer:
c = 5
Step-by-step explanation:
A quadratic equation in standard form is
ax² + bx + c = 0 : a ≠ 0
Given
- 6 = x² + 4x - 1 ( add 6 to both sides )
0 = x² + 4x + 5 ← in standard form
with c = 5
