Explicação passo a passo:
Dado que:
Principal = 4000
Juros = 586
Taxa (r) = 29,3% ao ano = 0,293
Juros simples = principal * taxa * tempo
586 = 4000 * 0,293 * t
586 = 1172t
t = 586/1172
t = 0,5 anos
Tempo = (0,5 * 12) = 6 meses
B.)
principal = $ 90909,09
Montante final = 100.000
Taxa (r) = 12% = 0,12
Usando a fórmula:
Quantidade final = p (1 + rt)
Taxa = r; t = tempo
100000 = 90909,09 (1 + 0,12t)
100000 = 90909,09 + 10909,0908t
100000 - 90909,09 = 10909,0908t
9090,91 = 10909,0908t
t = 9090,91 / 10909,0908
t = 0,8333334
Número de meses:
0,8333334 * 12
= 10 meses
How To: Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm..
Answer:
A and D
Step-by-step explanation:
because the equation shows that they are both relatively right
Answer:
Sample Space = {SSS,SSF,SFF,SFS,FSS,FSF,FFS,FFF}
Step-by-step explanation:
Given a sale representative makes presentations about a product in three homes per day.
In each home, Sale is denoted by S and No Sale is denoted by F.
Now the cases for required sample space will be :
- Sale in first home, Sale in second home and Sale in third home.
- Sale in first home, Sale in second home and No Sale in third home.
- Sale in first home, No Sale in second home and No Sale in third home.
- Sale in first home, No Sale in second home and Sale in third home.
- No Sale in first home, Sale in second home and Sale in third home.
- No Sale in first home, Sale in second home and No Sale in third home.
- No Sale in first home, No Sale in second home and Sale in third home.
- No Sale in first home, No Sale in second home and No Sale in third home.
So our Required sample space for the experiment
= {SSS,SSF,SFF,SFS,FSS,FSF,FFS,FFF}.
Answer:
x = 15
Step-by-step explanation:
3x - y = 30
Given;
y = 15
To find;
value of 'x'
Putting the value of y in the given equation;
3x - 15 = 30
3x = 30 + 15
3x = 45
x = 45/3
x = 15
