Answer:
B SSA
Step-by-step explanation:
Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.
However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.
C) 18 because you could get 6 numbers with red, 6 numbers with brown and 6 numbers with yellow.
TRUE because 8/15 = 0.53 which is less than 3/5 = 0.60
You can factor out the square root of two from the num and denom of this fraction leaving you with 1/3 or 1.33
7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
