Answer:
There are 60 permutations.
Step-by-step explanation:
Arrangements formula:
The number of possible arrangements of n elements is given by:
With repetition:
For each element that repeats, with 
times, the formula is:
In this question:
Apple has 5 letters.
P appears two times. So
There are 60 permutations.
3600 if you multiply 40 to 80<span />
Answer:
The rotational angle of a regular polygon with 72 sides is 5º.
Step-by-step explanation:
The rotational angle (
), measured in sexagesimal degrees, of polygon of 
sides is the angle of a complete revolution divided by the number of sides (). That is:
(1)
If we know that 
, the rotational angle is:
The rotational angle of a regular polygon with 72 sides is 5º.
Answer:
The answer to your question is: letter B
Step-by-step explanation:
Function definition: a function is a relation from a set of inputs to a set of outputs.
The most important about functions is that each input is related to one and only one output. Then there are not repeated values of inputs.
In the exercise, the inputs are -10, -25, -5, and the outputs are 5, 10, 15 and 20.
So, to solve this exercise, look for a number in the options that will not be repeated in the inputs,
Then,
- 20 is a possible option because is not repeated
-5 is not an option to complete the table because 5 already exist.
- 15 is a possible option because is not repeated previously.
Answer:
S = 13 - x
T = (18 + x) / 2
Step-by-step explanation:
S = 18
T= 18
Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.
S = 18 - x
T= 18 + x
Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.
S = 18 - x - 5
T = 18 + x / 2
Simplify 18-5.
S = 13 - x
T = (18 + x) / 2
