Answer:
x=18
Step-by-step explanation:
all the interior angles in a pentagon = 540. use to interior angle theorem. then just add all the angles up and make them = to 540 like this: 540=95+90+(7x-4)+(3x+23)+(9x-6). then solve using algebra
Answer:
5190 g
Step-by-step explanation:
Calculate the volume:
28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³
Density is mass divided by volume:
D = M / V
Solving for mass:
M = D V
Substituting values:
M = (10.50 g/cm³) (493.92 cm³)
M = 5186.16 g
Rounding to three significant figures, the mass is 5190 g.
