76÷2 = 38. 38 es la solución.
SA= 2LW + 2LH + 2WH
Substituting for the values, SA = 900 cm^2
So change from 50 to 35
first find change
50-35=15
50=100%
15=x%
percent means parts out of 100
15 out of 50=x/100
15/50=x/100
30/100=x/100
30=x
the answer is 30% change
Answer:
Option D.
Step-by-step explanation:
Precision refers to the the level of measurement and exactness of a measurement. The mean diference between '<em>precision</em>' and '<em>exactness</em>' is that if a measuring device gives consisten measurements it's considered precise, but it's not necessarily accurate.
For example, a measurement of 2.365m is more precise than a measurement of 2.3m, given that 2.365m has more significant figures and was made with an instrument that has higher precision. This doesn't mean that the measurement is accurate, the real value could be 3m for example! ✅
