Answer:
Step-by-step explanation:
1a = yes
1b = no, you don’t add the denominators together when adding.
1c = yes
1d = yes
So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.
So, after this you would have to find a number that would go into 60 four times which is 15.
So, your answer would be 15.

S(t) = 3.82 - 0.2t
Step-by-step explanation:
After 7 weeks, the ice is 2.42 meters thick. The ice loses 0.2 meters of thickness per week; this means on the 7th week, it has lost 7(0.2) = 1.4 meters of thickness.
This means the ice started at 2.42+1.4 = 3.82 meters thick.
Our function will start at the original thickness of the ice, 3.82 meters.
Since the ice is losing thickness, we will subtract; it loses at a rate of 0.2 meters per week (t), which gives us 0.2t. This is subtracted from the original, 3.82 meters, giving us
S(t) = 3.82 - 0.2t
The graph on the left is correct
560 meters. Hope this helps!
