$(- \frac{5}{10} )( \frac{ x^{3} }{ x^{3}} } )( \frac{ y^{3} }{ y^{3} y^{4} } )( \frac{z^{4} }{ z^{4} } )$ => $(- \frac{1}{2} )( \frac{1}{ y^{4} } ) => \frac{-1}{2 y^{4} } .$

Mr. Schordine wants to fill up enough helium balloons to allow him to fly through the skies. He weighs 84 kilograms. He knows th

Cerrena [4.2K]

Answer:

There is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.

Step-by-step explanation:

First, we need to calculate the volume of each balloon by considering the balloons as a sphere:

$V = \frac{4}{3}\pi r^{3}$

Where:

r: is the radius = 0.4 meters

$V = \frac{4}{3}\pi r^{3} = \frac{4}{3}\pi (0.4 m)^{3} = 0.27 m^{3}$

Knowing that 1 m³ of helium is able to lift about 1 kg, that Mr. Schordine weights 84 kg, and that each ballon has 0.27 m³ of helium, the number of balloons needed are:

$N = \frac{1 m^{3}}{1 kg}*84 kg*\frac{1 balloon}{0.27 m^{3}} = 311.1 \: balloon$

Therefore, there is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.

I hope it helps you!

The slope of the line passes through the points (3,-6) and (7,y) is -2/3. Find y.

kirza4 [7]

-6-y / 3-7 = -2/3

-6-y / -4 = -2/3

Multiply through by -12:-
3(-6-y) = 8

-18 - 3y = 8
3y = - 26

y = -8 2/3
