Answer:
194.5315427 grams
Step-by-step explanation:
The half-life of element x would be 66 years. So, after 20 years you would have:
.5^(20/66) x 240=0.810548 x 240
=194.5315427 grams of the element left ......
Answer:idk
Step-by-step explanation:
Use photomath
The number of times the image of the octagon will coincide with the preimage during rotation is determined by:
N = R/C
where
N is the number of times the preimage coincided with the rotated image during rotation
R is the angle of rotation
C is the central angle of the regular polygon
For an octagon, the central angle is
C = 360/8 = 45
So,
N = 360 / 45 = 8
Therefore, the rotated image of the octagon will coincide with the preimage 8 times during rotation.
