If this can be modelled by exponential decay, therefore
the function must be in the form of:
A = Ao (1 + r)^t
where A is the final value, Ao is the initial = 15000, r
is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20
A = 15,000 (1 – 0.0015)^20
A = $14,556.36
The measurements of the box actually aren't needed since they already gave you the surface area. Just multiply the given surface area by the price of wrapping paper per square inch: 182.5 x $0.012 = $2.2224. If you round that answer, you'll know that it costs $2.22 to wrap the gift.
a) - 14/9 or as a mixed number -1 5/9
b) 13/25
c) -1/30
d) 2/5
Answer:
2.9 = c
Step-by-step explanation:
-23 = -8c
/-8 /-8 (-8 cancels)
2.9 = c
Answer:

Step-by-step explanation:
Hey There!
If you divide a whole number from a fraction all you have to do is multiply the dividend (7) by the divisor ( denominator) ( aka 18)
18x7=126
so the simplified version would be

Hope this helps :)
