Answer:
0.79
Step-by-step explanation:
8 jars because you subtract 0.56 from 6. Afterwards, you divide the difference which is 5.44, by 0.68 and get eight.
Answer:
Tn = 6.4 + 1.8n
Step-by-step explanation:
Given
Sequence: 8.2, 10, 11.8, 13.6
Required
The formula of the sequence.
First, the type of the sequence needs to be determined (arithmetic or geometric)
It is an arithmetic sequence because each successive sequence is separated by a common difference..
The common difference is represented by d and it's calculated as follows.
d = 10 - 8.2 or 11.8 - 10 or 13.6 - 11.8
Each of the above gives
d = 1.8
Now, that we have the common difference; the next is to determine the formula using the Arithmetic Progression formula.
Tn = T1 + (n - 1)d
Where T1 is the first term of the progression; T1 = 8.2
By substituting 8.2 for T1 and 1.8 for d.
This gives
Tn = 8.2 + (n - 1) * 1.8
Open bracket
Tn = 8.2 + 1.8 * n - 1 * 1.8
Tn = 8.2 + 1.8n - 1.8
Collect like terms
Tn = 8.2 - 1.8 + 1.8n
Tn = 6.4 + 1.8n
Hence, the formula of the sequence is Tn = 6.4 + 1.8n
The answer is 1414. Multiply the tickets and the dollars for both Andrea and Nick. Then add both there totals.
Answer: One possible way: 123 - 45 - 67 + 89
Step-by-step explanation: The goal is to get 100, using all of the following numbers: (1,2,3,4,5,6,7,8,9)
We can merge numbers to get 100.
123 - 45 - 67 + 89 (We used every number once)
Lets solve from left to right.
123 - 45 = 78. 78 - 67 = 11. 11 + 89 = 100.
