Answer:
≈23.6 kg left.
Step-by-step explanation:
For determining this, we can simply use an exponential decay equation representing this scenario:
a: the initial amount
t: the amount of time
h: the half life
Now, substitute the numbers into the equation:

Now, solve this equation:

Use a calculator to solve for y:
y= 200(0.118)
y≈23.6 kg left.
Answer:
7 days
Step-by-step explanation:
35% of 20 =
.35 * 20 = 7
Let the length is x and the width is y
x - y = 4 .........(1) 2x + 2y = 12
x + y = 6........(2)
by adding 1 and 2
2x =10 , x = 5
y = 1 inch
Answer:
C (x-8)(x-5)
Step-by-step explanation:
(5-8) = -3
(5-5) = 0
-3 x 0 = 0
