Which expression is the simplest form of (27x^-9)^1/3?

lana [24]

$\sqrt[n]{a^m}=a^\frac{m}{n}\\\\\sqrt[n]{a}=a^\frac{1}{n}\\\\(a^n)^m=a^{nm}\\\\(a\cdot b)^n=a^n\cdot b^n\\\\(27x^{-9})^\frac{1}{3}=27^\frac{1}{3}(x^{-9})^\frac{1}{3}=\sqrt[3]{27}\cdot x^{-9\cdot\frac{1}{3}}=3x^{-3}=\dfrac{3}{x^3}$

A kite has A = 120 cm2 and d1 = 16 cm. Identify the length of d2.

neonofarm [45]

Answer:

d₂ = 15 cm

Step-by-step explanation:

The area (A) of a kite is calculated as

A = $\frac{1}{2}$ d₁d₂

Here A = 120, d₁ = 16 , then

$\frac{1}{2}$ × 16 × d₂ = 120

8d₂ = 120 ( divide both sides by 8 )

d₂ = 15 cm

The Green family is a family of six people. They have used 4,885.78 gallons of water so far this month. They cannot exceed 9,750

svetoff [14.1K]

Answer:

The inequality is $6x+4,885.78\leq 9,750.05$

$x\leq 810.71\ gal$

Step-by-step explanation:

Let

x -----> amount of water that can be used by only one family member for the rest of the month

we know that

$6x+4,885.78\leq 9,750.05$

Solve for x

Subtract 4,885.78 both sides

$6x\leq 9,750.05-4,885.78$

$6x\leq 4,864.27$

Divide by 6 both sides

$x\leq 4,864.27/6$

$x\leq 810.71\ gal$ ---> maximum amount of water that can be used by only one family member for the rest of the month
