First, let's start with the whole number.
Half of 5 is 2.5 or 2 1/2.
4/5 translated into a decimal is 0.8, so half of that would be 0.4.
0.4 translated into a fraction is 2/5.
Add 2 1/2 to 2/5.
I'll show you the long way and the easier way.
The long way is that you find a common denominator for both fractions.
A common denominator would be 10, because you would multiply 2 and 5 (the denominators).
So this would translate the problem into 2 5/10 (Remember that whatever you do to the bottom you have to do to the top) and 4/10.
If you add these together you get 2 9/10.
The easy ways is taking the decimals in the problem (2.5 and 0.8)
Half of 0.8 is 0.4 (As mentioned above).
2.5 + 0.4.
This equals 2.9.
The volume of the spherical piece is 288.55 cm³.
Solution:
Diameter of the sphere = 8.2 cm
Radius of the sphere = 8.2 ÷ 2 = 4.1 cm
The value of π = 3.14
Volume of the sphere
= 288.55 cm³
The volume of the spherical piece is 288.55 cm³.
Answer:
The Point C shows the location of 5-2i in the complex plane: 5 points to the right of the origin and 2 points down from the origin.
Step-by-step explanation:
We have the complex number 5-2i and we have to show the location of the point that represents that number in the complex plane
In the complex plane the real numbers are located in the horizontal axis, increasing to the right. The positives real numbers are at the right of the origin and the negatives to the left.
The complex numbers are located in the vertical axis, with the positives over the origin and the negatives below the origin.
This complex number 5-2i is the sum of a real part (5) and a imaginary part (-2i), so the point will be 5 units rigth on the horizontal axis (for the real part) and 2 units down in the vertical axis (for the imaginary part).
