You can round yourself.
Answer: No, it is not.
Step-by-step explanation:
In order to solve this exercise it is important to remember the definition of "Integers".
Integers are defined as those numbers that do not have a fractional part. Integers contains:
1. The positive numbers (these are the numbers greater than zero):
2. The negative numbers (these are the numbers less than zero):
3. The zero:
It is also necessary to remember the definition of "Decimal numbers".
Decimal numbers are those numbers that have a whole part, a fractional part and a point that separates these parts. That point is called "Decimal point".
Then, given the following number:
You can identify that it has a whole part and a fractional part separated by the Decimal point. Therefore, that number it is not an Integer.
Answer:
Approximately 28 times
Step-by-step explanation:
The tires are circular in shape.
We first need to find the circumference of the tire and then divide the length of the road by that circumference.
The circumference of a circle is given as:
C = πD
where D = diameter
The diameter of the tires is 1.7 m. Its circumference is therefore:
C = π * 1.7 = 5.34 m
Therefore, the number of times that the tire has to turn in traveling the length of the street is:
149 / 5.34 = 27.9 ≅ 28
answer
objects are pulled toward Earth's center? Earth has a magnetic force that is strongest at its core. Earth has a much greater mass than objects on its surface. The weight of the atmosphere pushes objects toward Earth's surface
