Step-by-step explanation:
Things to remember:
1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.
Example:
2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.
Example: 2.0 × 100 = 200
In this question, 0.014 × 100000 = 1400.000
Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.
Answer:
The equation that models the relationships between , the number of hours Mark reads, and ,
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value as Mark starts reading from 0.
So, the equation is:
