Sold DVD for 50% more of the purchase price of $12
so 12 + 50/100 (12)
=12+6
18

So customer will pay 7% tax on $18

Hence he will pay 18 (1.07)$
= $19.26

Hope this helps

Maya says that value of the 6 in 0.006 is 1/10 of the value of the 6 in 0.6 . Is she correct? Explain
Nikolay [14]

Answer:

Maya is NOT correct  as

\frac{1}{1000} is  1/100 of the value \frac{1}{10}

Step-by-step explanation:

The value of 6 in 0.006 = \frac{1}{1000}

Also, the value of 6 in 0.6  = \frac{1}{10}

But, \frac{1}{1000} is not 1/10  of the value  \frac{1}{10}

as 1/10  of the value  \frac{1}{10}  =  \frac{1}{100}

Hence,Maya is NOT correct.

\frac{1}{1000} is  1/100 of the value \frac{1}{10}

The function f is such that f(x) = x^2 – 2x + 3
aev [14]

Answer:

x = - 4, x = 6

Step-by-step explanation:

Given

f(x) = x² - 2x + 3 and f(x) = 27, then equating the 2 gives

x² - 2x + 3 = 27 ( subtract 27 from both sides )

x² - 2x - 24 = 0 ← in standard form

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 2)

The factors are - 6 and + 4, since

- 6 × 4 = - 24 and - 6 + 4 = - 2, thus

(x - 6)(x + 4) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 4 = 0 ⇒ x = - 4
