First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
Answer:
-250
Step-by-step explanation:
assuming he starts at 0 pts -50 * 5 = -250
Answer:
-81
Step-by-step explanation:
Because the triangles are congruent we know that NM = ST = 50.
answer: 50
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
