Answer:
w = 400
Step-by-step explanation:
2400 = lw
Divide the area by two.
2400 / 2 = 1200
Now this cannot be the answer since the length is longer than the width.
Divide 1200 by two again.
1200 = 600
Notice there are two choices that are the closest:
w = 800
w = 400
The latter choice would be the answer since again, the length is longer than width in terms of measurement
Answer: It's (3,-2)
Step-by-step explanation:
Answer:
18.05 g
Step-by-step explanation:
The multiplier of the initial quantity is ...
(1/2)^(t/1690)
so, for t=250, this becomes ...
(1/2)^(250/1690) ≈ 0.902545
Then the quantity remaining of the initial 20 g is ...
(20 g)(0.902545) ≈ 18.05 g
