The common ratio between terms is 3, so the sequence has general 
-th term
for 
. The term exceeds 7000 when
which means the first time 
exceeds 7000 occurs when 
. Indeed,
while the previous term would have been
Ron must work 9 hours. If he makes 300 every 5 hours, that means he makes 60 every hour. 60x9 = 540
Answer:my
The height of the stack will be 9.15×10^20_m
Or 9.15×10^17_Km
Which is 6 billion times more more than the distance to the sun
Or 22.9 million times further than the star Proxima Centauri
Step-by-step explanation:
Given
Avogadro's number = 6.02×10^23 particles
And the thickness of a penny = 1.52_mm
The height of the stack will be
1.52 × 6.02 ×10^23 = 9.15×10^23_mm 9.15×10^20_m
Isolate the variable by dividing each side by factors that don't contain the variable.
-6x-15+15=4x+35+15
-6x=4x+50
(Subtract 4 on both sides)
-10x=50
(Divide by 10 on both sides)
x=5
