Here are the methods you can use when multiplying a whole number and a decimal. In multiplying a whole number, you can just do the normal multiplication process and the product would still be a whole number. In multiplying a decimal, it becomes different because the decimal points will affect the product. In multiplying decimal, each time we multiply by a power of 10, the decimal point is moved one place to the right. <span>When multiplying a decimal by a whole number, placement of the decimal point is very important. When a given number has 2 decimal places, the product must also have two decimal places. Hope this explanation helps.</span>
2|3x + 5| = -10 . Divide both sides by 2:
|3x + 5| = -5 ===>3x+5=-5 & -3x-5=-5 In both cases x=0
Answer:
Ratio
Step-by-step explanation:
Voltage measurement of batteries involves ratio level of measurement because it has a significant zero i.e. zero voltage of the battery will mean no voltage. The mathematical operations of multiplication, division, addition and subtraction are meaningful in ratio level of measurement. The mathematical operations of multiplication, division, addition and subtraction on voltage measurement of batteries are meaningful.
Thus, voltage measurement of batteries involves ratio level of measurement.
You didn't put any options but any ratio that 4.2:1 doesn't go into is not equivalent.
Hope this helps :)
Answer:
The range is [10, ∞).
Step-by-step explanation:
This is the equation of a parabola which opens upwards and has a minimum value of 10 ( because of the + 10:- the vertex is at (5, 10).
