A 4 side shape with sides congruent
Answer:
9.4
Step-by-step explanation:
Given :
LM= 22, NO = 6, and LN= 14 ; MO = x
Since O bisects the triangle ;
LN / NO = LM / MO
14 / 6 = 22 / x
Cross multiply :
14 * x = 22 * 6
14x = 132
Divide both sides by 14
14x/14 = 132 / 14
x = 9.428
x = 9.4 ( 1 decimal place)
C. the addition property of equality
Answer:
0.025 grams
Step-by-step explanation:
The water in the stopcock has a volume of 25 mL initially, After that, the whole water was drained out. So we have:
Volume of drained water = (25 mL)(1 x 10⁻⁶ m³/1 mL)
Volume of drained water = 25 x 10⁻⁶ m³
Density of drained water = 1000 kg/m³
So, for the mass of drained water:
Density of drained water = Mass of drained water/Volume of drained water
Mass of drained water = (Density of drained water)(Volume of drained water)
Mass of drained water = (1000 kg/m³)(25 x 10⁻⁶ m³)
<u>Mass of drained water = 0.025 gram</u>
Density
