Answer:
48 + 18√13 cm²
Step-by-step explanation:
HC = BC/2 = 4m/2 = 2 m
AC = √AH² + HC² = √9 + 4 = √13
A = 2×A(ABC) + 2×A(ACFD) + A(BCFE)
= 2×AH×BC/2 + 2×AC×CF + BC×CF
= 2×3×4/2 + 2×√13×9 + 4×9
=12 + 18√13 + 36
= 48 + 18√13 cm²
Answer:
30% because the chance of the whole dice is 6
I don't know if this is the answer that you are looking for, but would the answer be all solutions?
Sample space ={6y+11b+15g+3bk} = 35 elements
number of black rings=3
probability (black ring) =3/35=0.085
A squared plus B squared equals C squared, so what you need to do it square 5 and 7.
5 = 25
7 = 48
Then add then and square root your answer. 48 + 25 = 73. 73 square rooted equals an rounded amount of 8.6. SO the answer is D
