How many 3/4 pound packages can you make with 6.5 pounds of sunflower seeds?
xz_007 [3.2K]

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Hope this helps!!

Please mark brainliest !

A solid object in the shape of a cylinder is shown below.
lozanna [386]

Answer:

0.08\ kg/m^3

Step-by-step explanation:

Density is defined as mass of an object divided by its volume.

#We calculate the volume of the cylinder:

V=\pi r^2 h, r=D/2=6/2=3\ cm\\\\=3.14\times 3^2\times 7\\\\=197.82\ m^3

Given the mass= 15.3kg and volume as above, we calculate density as:

\rho=\frac{Mass}{Volume}\\\\=\frac{15.3\ kg}{197.82\ m^3}\\\\=0.0773\approx 0.08\ kg/m^3

Hence, the solid's density is 0.08\ kg/m^3
