First problem.
Call a and b the sides. Since the sides are doubled they are 2*a and 2*b
You know the area is given by a*b.
2a*2b = 12
4ab = 12
So divide both terms for 4 :)
ab = 3 ft^2
Second problem.
Find the volume of the two solids.
The first contenitor is a parallelepiped.
V = abh
a = 10
b = 5
h = 6
V = 10*5*6 = 300 in^3
The second solid is a cilinder.
V = pi*r^2*h = 3^2*10*pi = 9*10*pi = 90pi in^3 = 90*3,14 = 282,6 in^3
The first contenitor hold more ice cream

Answer:
year 2343
Step-by-step explanation:
The population (in millions) of a certain country can be approximated by the
function:
P(x) = (100)*1.02^(x)
where x is the number of years after 2000.
If we want a population of 300 million
300.10^6 = (100)*1.02^(x)
3.10^6 = 1.02^(x)
Which can be solved with a calculator or any computational tool. See attached pictures
The answer is
x = 342.804
2000 + 342.804 = 2342.804 ≈ 2343
99.50 times .95
94.53
99.50+94.53
194.03
Answer:
$194.03
First comes exponents. -2.9 to the 7th power equals −1724.9876309. then multiple by -2.9 and you get 5002.46412961
