I pretty sure it is A. but please someone check behind me
Answer:
1. d=m/v
=57.6/112.9
=0.51018601
=0.510g/cm³(3s.f.)
2. m=d×v
=1.8×54
=97.2g
3. v=m/d
=63.8/12.7
=5.02362205
=5.02cm³(3s.f.)
4. v=length×breath×height
=12×2×6
=144m³
216g=0.216kg
d=m/v
=0.216/144
=0.0015kg/m³
Step-by-step explanation:
density=mass/volume
mass=density×volume
volume=mass/density
*make sure the units are correctly placed.
*g/cm³, kg/m³
Answer:
Remember, here -- with addition -- the parentheses are just extras there to throw you off track!
We can remove the parentheses:
7a + 9 + 4a - 7
Now simplify!
7a + 4a + 9 - 7
11a + 2
17, because you divide 22 in half and add 6 because there are half as many mollies and there are 6 more guppies then goldfish.
