69.7
Step-by-step explanation:
627 ÷ 9
=69.66666666666666
approximately
69.7
3p = 4 - 9p
+9p + 9p
------------------
12p = 4
divide both sides by 12
p= .333 repeating or 1/3
This is obviously a decreasing sequence. Thus, the common ratio is the fraction 1/4, not the integer 4. Eliminate C and D. Next, at n=1, the value of the 1st term is 16, which is actually 16(1/4)^(1-1) = 16(1) = 16. Thus, B is correct.
(3x^2- 5)(x^2+2) that is the answer
Answer:
x*(2/3)=y
y*1.5=x
Step-by-step explanation:
There is 2/3rds the amount of sodium in the new one, y. If you multiply the odl one, x, by 2/3, you'll have the amount in the new one. Because half of 2/3rds is 1/3, if you multiply the new one by 1.5, you'll end up with 3/3, or 1, which is the amount in the old one.
