Responda:
Preço = $ 400
Explicação passo a passo:
Dado que:
Primeira opção :
Pagamento em 5 investimento igual
Segunda opçao :
Pagamento feito em 8 iguais. Investimento
O preço por parcela do primeiro investimento é 30 a mais do que cada um do segundo
Deixe o preço do telefone = p
Valor por prestação = x
Segunda parcela:
Preço = 8x
Primeiro :
Valor por parcela = x + 30
P = 5 (x + 30)
Preço = 5x + 150
Portanto, igualando as duas equações:
8x = 5x + 150
8x - 3x = 150
5x = 150
x = $ 50
Usando qualquer das equações de preço:
Preço = 8x
Preço = 8 * 50
Preço do telefone = $ 400
Answer:
y=70°
z= 60°
w= 70°
Step-by-step explanation:
Since the two triangles are similar, we know that all of the corresponding angles must be the same. On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°. This means that the same angle is formed at Z, which is in the same location on the triangle to the right. From there, we can find the missing angle, W, from the difference of 180°.
180°-50°-60°=70°.
The same way we found Z, we can also find Y, since it has to be the same as W.

</span>Sam wants to write an equation to represent a proportional relationship with a constant of proportionality of 6. He writes the equation y = 6 + x.
B. 6
Since 3 is too short and we know BW is longer than WE
Answer:
Bank B because the more often you compound interest, the more interest you earn.
Step-by-step explanation:
Bank A compounds the interest once a year.
Bank B compounds the interest twice a year.
Let's create an example of two investments of the same amount of money, the same interest rate, and the same time. The only difference will be the number of times the interest is compounded per year.
Compound interest formula:

where
A = future value
P = principal invested
r = interest rate
t = number of years
n = number of times interested is compounded in 1 year
Example:
P = $1000
r = 5%
t = 5 years
Bank A: n = 1
Bank B: n = 2
Bank A:

Bank B:

Bank A's investment is worth $1276.28 after 5 years, but Bank B's investment is worth $1280.08 after the same 5 years. Compounding twice per year instead of only once per year earns more interest.
