Answer:
.018 Kg/cm^3
Step-by-step explanation:
Density (P) is equal to the mass (9.9g) divided by volume (.55cm^3)
= 18g/cm^3
=.018kg/cm^3
3x +5x =90 +30
8x =120
x =15
15 : 5 = 3 : 1
Can you give me hint
than I can answer
109.3 yard²
Area of triangle = bh / 2
base is 23yd
height is 9.5yd
bh / 2 = 23 × 9.5 / 2
Area = 218.5 / 2
Area = 109.25 yd²; rounded to the nearest tenth is 109.3yd²
x^2+2x+1
