Answer:

The watermelon candies taste $0.13 more.

Step-by-step explanation:

First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.

Find the values of s1 and r for a geometric sequence with s4 = 18 and s6= 8<br>​
stiv31 [10]

Answer:

  see below

Step-by-step explanation:

The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:

  s6/s4 = r^2

  r = √(8/18)

  r = 2/3 . . . . . matches choices A and C

__

Using the formula for the general term, we now know enough to find the first term:

  sn = s1·r^(n-1)

  s4 = s1·(2/3)^(4-1)

Using s4 = 18 and multiplying by (2/3)^-3, we get ...

  18·(2/3)^-3 = s1 = 18·27/8

  s1 = 243/4 . . . . . matches choice A

23)  8/p = 3/10

       
80 = 3p
