the sales tax for an item was $30.10 and it cost $430 before tax. find the sale tax rate. write your answer as a percentage.
timurjin [86]
To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10  The sale tax rate is 7%.

Responder:

$ 16,2

Explicação passo a passo:

No dia da festa, Bianca comprou os pastéis por US $ 5,20, duas maçãs do amor por US $ 3,40 e dois refrigerantes por US $ 7,60. Quanto bianca você gastou?

O valor gasto por Bianca é a soma de todos os itens que ela comprou:

Pastelaria = $ 5,20

Maçãs do amor = $ 3,40

Refrigerantes = $ 7,60

A soma da soma dá o valor gasto de Bianca:

Doces + Maçãs do Amor + Refrigerante

$ (5,20 + 3,40 + 7,60)

= $ 16,2

If cos A = k, then the value of the expression (sin A)(cos A)(tan A) is equivalent to:
sukhopar [10]

Answer:

1-k^2

Step-by-step explanation:

tan A= sin A/cos A

(sin A)(cos A)(sin A/cos A)=(sin A)^2

(sin A) ^2 + (cos A) ^2= 1

(sin A) ^2=1-(cos A) ^2

(sin A)^2= 1 - k^2
