Between 1994 and 1998 the population increased by 5 miliion, approximately 1 1/4 million a year.
2016 - 1998 = 18 years at 1 1/4 million a year = 22 1/2 million
Estimate therefore is: 81 + 22 1/2 = 103 !/2 million
Answer:
Answer b of the first one
answer of q9
Step-by-step explanation:
(x+iy)(2−3i)=4+i
2x−(3x)i+(2y)i−3yi

=4+i
Real
2x+3y
+
Imaginary
(2y−3x)
i=4+i
Comparing the real & imaginary parts,
2x+3y=4--------------------------(1)
2y−3x=1----------------------------(2)
Solving eq(1) & eq(2),
4x+6y=8
−9x+6y=3
13x=5⇒x=

Answer:
2.2084384 in cents, and 22.084384 in dollars
Step-by-step explanation:
Apologies in advance if I've got something wrong, it's currently 12:08 at night for me njnhrj
First we'd like to figure out how much we have after calculating the weight left over after charging for the first ounce.
7.90137-1=6.90137
Multiply by .32, and you've got your sum in cents; 2.2084384
Divide this by 0.1 and you've got it in dollars; 22.084384

Volume = πr²h
---------------------------------------
Find Volume of one tank
---------------------------------------
Volume of 1 tank = πr²h
Volume of 1 tank = 3.14 x 6² x 12
Volume of 1 tank = 678.24 ft³
---------------------------------------
Find Volume of 5 tanks
---------------------------------------
Volume of 1 tank = 678.24
Volume of 5 tanks = 678.24 x 5
Volume of 5 tanks = 3391.2 ft³
