You can first convert everything to ounces and then subtract, when you get your answer convert it back to lbs.
*16 oz = 1 lb
12 lbs 5 oz = 197 oz
7lbs 10 oz = 94 oz
197 - 94 = 103
103/16
= 4 lbs and 7 oz
hope this helps :)
Answer:
Step-by-step explanation:
Given
--- Initial Amount
every 10 years
Required
The remaining amount after 300 years
To do this, we make use of:
Where
r = decay rate
T = the period of decay
In 300 years, there are 30 periods of 10 years.
i.e.
You'll actually need to graph for the first segment
but the second part can be solved with algebra
The equation of the line is y(x)=-x
if we test the co0ordinates we can find if the point lies on the line
(5,5)
y(x)=-x
Using the x co-ordinate
y(5)= -5
y=-5
Leaving us with (5,-5)
Because (5,-5) is not (5,5)
This is not a point on the line
The slope of the line is -1
Area of a rectangle is Length times width
So basically 380 * 280 should be the answer
The answer should be 106400
423 divided by 898 is 0.47104677...
Hope I could help! :)
