<span>A store display rotates 40 times every half hour i.e 30 minutes
Thus, by simple calcultion, we say,
Therefore, the store display rotates 80 times in 1 hour i.e. 60 minutes
Now,
Thus, the strore display will rotate 80*4 = 320 times in 4 hours
therefore, the answer is 320 times in 4 hours</span>
Answer:
i wanna say its the first one if its wrong im very sorry
Step-by-step explanation:
The formula for compound interest is:
A=P(1+r)^n
where is
P=principal=10,500
r=interest as a percent=2.99/100=0.0299
n=years
A=10,500(1+0.0299)^5=10500*(1.0299)^%=10500*1.158=12166.47
choice A
Answer:
y+3=-3(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=-3
y-(-3)=-3(x-(-1))
y+3=-3(x+1)
