1) Complete the sentences to explain how to multiply 4.56 x 1,000.
1 answer:
Answer:
The decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.
Step-by-step explanation:
Multiplication of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the right.
Division of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the left.
In this question:
We multiply the decimal 4.56 by 1000.
1000 is the 3rd power of 10, because . So the decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.

Answer:
Part 1) Slope-intercept form
Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
Step-by-step explanation:
Part 1) we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
This is a linear equation in slope intercept form
where
Part 2) we have that
x -----> represent the number of miles
y ----> represent the total charge in dollars
The slope is
---> unit rate
The y-intercept is
----> initial value or flat fee
therefore
The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
