Answer: 0.0667117 * 
miles
Step-by-step explanation: The Earth is one astronomical unit from the sun i.e.1AU= 93 million miles.The angular speed of the Earth traveling around the sun is approximately 0.9863 degrees per day. If we assume the orbit of the Earth is completely circular, what is the linear speed in miles per hour?
Step-by-step explanation: First, a day has 24 hours. Knowing how far the earth travels in day we can say:
0,9863 degrees/day = 0,9863 degrees/(24 hours)
0,9863 degrees/day = 0.0411 degrees/hours
Also, we know the orbit completely circular, so the total distance on, degrees, is 360°. Also this distance can be know with the formula:
Total Circuference = 360° = 2*pi* R
Because Radius is variable for any circle. It is say that:
360° = 2*pi radians
WIth this relation, we can know how many radians are 0.0411 degrees
360/0.0411 = (2*pi)/x
x = (2*pi*0.0411)/(360)
X = 0.00071733032
X is how much the Earth travels per hour in Radians.
Multiplying per Radius:
Earth distance traveled per hour = 0.0667117 * miles
Answer:
Explanation with the help of discrete variables and continuous variables.
Step-by-step explanation:
We have to tell that which of the following can be an exact number.
This can be done with the approach of discrete and continuous variables.
Discrete variables are the variables that are countable and cannot be expressed in decimal form. They are point estimated.
Continuous variable are the variable that are estimated with the help of an interval. Their values can be expressed with the help of a decimal expansion. They are not countable.
a) Mass of a paper clip, Surface are of dime, Inches in a mile, Ounces in pound, microseconds in a week
Since all mass, area, weight(ounces), time, length(inches) are continuous variable, they can be estimated with the help of an interval. Thus, they can have exact number but not always.
b) Number of pages in a worksheet
Since this is a discrete quantity and it is countable. Thus, it will always have a point estimation and are exact numbers always.
