This is because of the order of operations:
Parentheses
Exponent
Divide
Multiply
Add
Subtract
Note that parentheses are the first, so it will affect everything after it.
Examples:
2(5+4)= 2x9= 18
(2x5)+4= 10+4= 14
5/(2+3)= 5/5= 1
(5/2)+3= 2.5+3= 5.5
Answer:
Step-by-step explanation:
Geometric sequences:
The nth term of a geometric sequence is given by the following equation.
In which r is the common ratio.
This can be expanded for the nth term in the following way:
In which 
is the first term.
In this question:
a. If the pattern continues, what explicit formula can be used find the distance of the nth swing?
Answer:
AD = 85
Step-by-step explanation:
AD = AB + BC + CD ( substitute values , noting AB = CD = 20 ) , then
AD = 20 + 45 + 20 = 85
Answer:
11.4 and/or 11 2/5
Step-by-step explanation:
You can turn 22 4/5 into a decimal which is 22.8 and divide that by 2 and it gets you 11.4. You can also turn 22 4/5 into an improper fraction which is 114/5. Multiply that by 1/2 which is 11 2/5.
Your answer is 7.
I subtracted 5 from 12 to find the missing number for KL that is 7.
Therefore, your answer is 7
