Answer:
120/99 is the answer.
Step-by-step explanation:
It has a line over it means that after the point there are infinite numbers of 21.
•Multiply 1.212121... with 100
we get 121.212121...
•Subtract it with the original one
121.212121.. - 1.212121... = 120.000.. = 120
Write it as an equation :-
Let the fraction be x.
(100×x) - x = 120
100x-x = 120
or, 99x = 120
so, x = 120/99
Answer:216 in^3
Step-by-step explanation:
Length=L
Surface area=216
surface area=6 x L^2
216=6xL^2
Divide both sides by 6
216/6=(6xL^2)/6
36=L^2
L^2=36
Take the square root of both sides
√(L^2)=√(36)
L=6
Volume of cube=L x L x L
volume of cube=6 x 6 x 6
Volume of cube=216

Answer:
$2,323.2
Step-by-step explanation:
A = P(1 + r/n)^nt
Where,
A = future value = ?
P = present value = 2,000
r = interest rate = 5% = 0.05
n = number of periods = 12
t = time = 3 years
A = P(1 + r/n)^nt
= 2,000(1 + 0.05/12)^12*3
= 2,000( 1 + 0.00417)^36
= 2,000( 1.00417)^36
= 2,000(1.1616)
= 2,323.2
A = $2,323.2
Use the substitution method
5x+18x
5(6)+18(6)
30+18(6)
Mutiply first then add
30+108
= 138
Answer: 138
