Question 6 (5 points)

Mathematics
1 answer:
Elena L [17]3 years ago
5 0

Answer:

2) 284.2 kg

Step-by-step explanation:

<u>Density, mass and volume</u>

We know the density of certain mass m who occupies a volume v is:

\displaystyle \rho =\frac{m}{v}

Our hot air balloon holds a volume of 1,592 m^3 of helium. Knowing the density of helium is 0.1785 kg/m^3, we can solve for the mass

m=\rho v

m=(0.1785)(1,592) = 284.172\ kg

Rounding to the nearest tenth:

m=284.2\ kg

The correct option is 2)

Find the exterior angle of angle c.
Bingel [31]

Answer:

Step-by-step explanation:

This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.

7x - 2 + 9x - 31 + 4x + 33 = 360

Combining like terms gives us

20x + 0 = 360 or simply

20x = 360 so

x = 18

In order to find the value of the angle exterior to angle C, we sub 18 in for x:

7(18) - 2 = 124
