The statue of liberty is 305 feet tall. A nearby building is 4/9 as tall. Find the height of the building.

inysia [295]

Answer:

The nearby building is $135 \dfrac{5}{9}$ feet tall.

Step-by-step explanation:

The statue of liberty is 305 feet tall.

A nearby building is $\dfrac{4}{9}$ as tall as the statue of liberty.

To find the height of the building, you need to find $\dfrac{4}{9}$ of 305:

$\dfrac{4}{9}\cdot 305=\dfrac{1,220}{9}= 135 \dfrac{5}{9}\ feet$

Thus, the nearby building is $135 \dfrac{5}{9}$ feet tall.

(3x+2)∧2=9 how do i solve this in the square root property

Irina18 [472]

$(3x+2)^2=9 \\\\9x^2+12x+4-9=0\\\\9x^2+12x-5=0\\\\a=9,\ \ b=12, \ \ c=-5$

$x_{1}=\frac{-b-\sqrt{b^2-4ac}}{2a}=\frac{-12-\sqrt{12^2-4 \cdot9 \cdot (-5)}}{2 \cdot 9}=\frac{-12-\sqrt{144+180}}{18}=\\\\=\frac{-12-\sqrt{324}}{18}=\frac{-12-18}{18}=\frac{-30}{18}=-\frac{5}{3}\\\\x_{2}=\frac{-b+\sqrt{b^2-4ac}}{2a}=\frac{-12+\sqrt{12^2-4 \cdot9 \cdot (-5)}}{2 \cdot 9}=\frac{-12+18}{18}=\frac{6}{18}=\frac{1}{3} \\\\Answer: \ x=-\frac{5}{3}\ \ and \ \ x=\frac{1}{3}$
