Answer:
−
10.5
Step-by-step explanation:
Short answer: 36.
This is a combination/permutation problem.
To put it simple, a die has 6 sides, there are 7 days but 1 is already determined (12 laps).
So if we multiple the options (sides on a die) × the number of days (6) we get:
6 × 6 = 36 possible outcomes.
To show this we can get
12, 13, 14, 15, 16, 17, 18
12, 13, 14, 15, 16, 17, 19
12, 13, 14, 15, 16, 17, 20
... all the way to
12, 18, 24, 30, 36, 42, 48
Answer:
1 : 51 2 : 39 3 : 90
Step-by-step explanation:
1 : 180(internal angle of triangle) - 90 - 39 =51
2. alternate angles
3. internal angles of rectangle are always 90
I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer: 
Step-by-step explanation:
The Arithmetic Sequence Formula is:
Where:
is the 
term of the sequence.
is the first term of the sequence.
is the term position.
is the common difference of any pair of consecutive numbers.
We can observe that the first term is:
Now, we need to find "d". This is:
Then, substituting, we get the following equation:
