For example:
(4/9) x=8
Now can solve this equation multiplying each side by 9/4.
(9/4)(4/9)x=(9/4)8
x=18
To check:
(4/9)(18)=(4*18)/9=72/9=8
The formula of a density is
p = M/V
where p is a density, M is a mass and V is a volume.
Given M = 3.4 kg and V = 2,300 mL or 2,300 cm<span>³, therefore
</span>p = 3.4 kg / 2,300 cm³ = 1.48 x 10⁻³ kg/cm³
3.125
to get this answer you divide 25 by 2, then divide that by 4, which equals 3.125
good luck hope I helped:)
460 i think because of the round of 50 is 60..
The formula is 1/2mv²
1/2*0.145*40²=0.0725*1600=116
Therefore the kinetic energy of that object is 116 joules.
