Question 6 (5 points)
(03.05 mc)
a hot air balloon holds 1,592 cubic meters of helium. the density of helium is 0.1785
kilograms per cubic meter. how many kilograms of helium does the balloon contain,
rounded to the nearest tenth of a kilogram? (5 points)
1) 432.3 kg
o2) 284.2 kg
o3) 2,043.7 kg
4) 5,435.3 kg

2) 284.2 kg

Step-by-step explanation:

Density, mass and volume

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

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

Rounding to the nearest tenth:

The correct option is 2)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

it is x equals 3   plese mark me really need it
