Answer:
2.57
Step-by-step explanation:
The common ratio of this sequence is ...
(1/3)/(3/15) = (1/3)/(1/5) = 5/3
Each additional term is 5/3 times the previous one, so the 8th term will be (5/3)^4 times the 4th term (the last one given). It is ...
(1/3)·(5/3)^4 = 625/243 ≈ 2.57
_____
The generic n-th term (an) is ...
an = a1·r^(n-1)
where a1 is the first term and r is the common ratio. We can make use of this formula to find the 8th term:
a8 = (27/375)·(5/3)^7 = (3^3/3^7)·(5^7/(3·5^3)) = 5^4/3^5 = 625/243 ≈ 2.57

Answer:
216 muffins were ordered
Step-by-step explanation:
81/x = 37.5%/100%
divide 37.5 by 100
81/x = .375
multiply x to both sides
×(x)= ×(x)
81 = .375x
divide both sides by .375
÷.375 = ÷.375
216 = x
x = 216
x = 216
Add -6 to both sides
square root x+6-6=7+-6
square root x=1
Solve square root
square root x=1
x= 1^2 ( square root both sides )
x=1
I hope that's help !
The median height is the one in the middle when placed in numerical order. Which in this case, it is 73. (the bolded numbers are those that are being crossed out)
72, 72, 73, 75, 78
72, 72, 73, 75, <span>78
</span>72, 72, 73, 75, 78
73 is the median height!
