1(x + 3) + 3(x - 1) = 20
1(x) + 1(3) + 3(x) - 3(1) = 20
               x + 3 + 3x - 3 = 20
               x + 3x + 3 - 3 = 20
                                4x = 20
                                 4      4
                                  x = 5

Taya2010 [7]

Answer:

Volume of Burj Khalifa Prism = 4000 cm^2

Volume of CN Tower Prism = 2671 cm^2

Step-by-step explanation:

Given

Height of Burj Khalifa = 828 m

Height of CN Tower in Toronto = 553 m

Base of rectangular prism is a square with sides <em>10 cm </em>\times<em> 10 cm</em>.

Height of Burj Khalifa prism = 40 cm

828 m is represented as 40 cm

\Rightarrow 553 m is represented as \frac{40}{828 } \times 553 = 26.71\ cm

So, height of rectangular prism of CN Tower = 26.71 cm

Volume of a Prism is given by the Formula:

V=Area\ of\ Base \times Height

Base is a square, so Area of base = Side^2

Volume of Burj Khalifa Prism:

V_B=10^2 \times 40 = 4000\ cm^2

Volume of CN Tower Prism:

V_C=10^2 \times 26.71 = 2671\ cm^2

So, the answer is:

Volume of Burj Khalifa Prism = <em>4000</em> cm^2

Volume of CN Tower Prism = <em>2671 </em>cm^2

Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams
