Answer:
The rules for adding and subtracting signed decimals are almost the same as the rules for adding and subtracting integers. When dealing with decimals, you need to be especially aware that your decimal points are lined up so that you do not accidentally add or subtract in the wrong place.
Answer:
Radius = r = 7.5
Diameter = d = 15
Circumference = C = 15π
Step-by-step explanation:
We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.
Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.
Circumference of the circle = C = 2πr
Using the value of radius(r), we can write the circumference as:
C = 2π(7.5) = 15π
A: For the Dentist, their average income in 30 years is $4,282,200
B: For the Manager, their average income in 30 years is $2,592,000
C: The difference in both their earnings is $1,690,200
Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.
I hope this helps you. :)
