Answer:
Step-by-step explanation:
<u>We can see points:</u>
- (1, 1), (2, 2), (3, 3) etc.
<u>It shows the proportional relationship:</u>
- y = x, where the slope is 1
A= l*w
168= 14*w
Divide both sides by 14
168/14= 14w/14
12=w
Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).

Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
3 piles of 9 pictures is 27. Because 9*3=27. So, your answer should say "Alise had 27 pictures in all because 9*3=27"
