Answer:

T-.5 = x (200)

Step-by-step explanation:

Let T = total time in hours

30 mn = .5 hours 30 /60 = .5

$ 2.00 is the rate per hour.

so T − .5 = the time that will be charged at the rate

Therefore the total charge is then

T − .5 × 2.00

Using the Pythagorean theorem we get:

$y^2+8^2=12^2.$

Simplifying the above result we get:

$y^2+64=144.$

Subtracting 64 from the above equation we get:

$\begin{gathered} y^2+64-64=144-64, \\ y^2=80. \end{gathered}$

Therefore:

$y=\sqrt{80}\approx8.9.$

Answer:

$y=8.9.$

What is 64x^6 + 27 written as a sum of cubes?

Talja [164]

Answer:

(4x² + 3)(16 $x^{4}$ - 12x² + 9)

Step-by-step explanation:

A sum of cubes factors as

a³ + b³ = (a + b)(a² - ab + b²)

64 $x^{6}$ = (4x²)³ ⇒ a = 4x²

27 = 3³ ⇒ b = 3

Hence

64 $x^{6}$ + 27

(4x² + 3)((4x²)² - (4x² × 3) + 3²)

= (4x² + 3)(16 $x^{4}$ - 12x² + 9)

Answer: 16

Step-by-step explanation:

multiplying by negative exponents can be a little tricky. So (1/4x)^-2 becomes 16/x^2 = __/x^2 so the missing number is 16
