Answer:
The Correct option is
A) Additive Inverse Property
.
Step-by-step explanation:
Identity Property of Addition
:
In math, an identity is a number, n, that when added to other numbers, gives the same number, n.
The additive identity is always zero.
This brings us to the identity property of addition, which simply states that when you add zero to any number, it equals the number itself.
Statement Reasons
1. -(a+b)+a = -a+(-b)+a 1.Distributive Property
= -a+a+(-b) 2.Commutative Property of Addition
= 0+(-b) 3. Additive Inverse Property
= -b 4. Identity Property of Addition
Find the value for
For the east direction
And (for the other direction of 105°)
Answer:
0.68
Step-by-step explanation:
p(white area) = (white area)/(total area of the circle)
The white area is the area of the triangle subtracted from the total area of the circle.
area of circle = (pi)r^2 = pi * (4 cm)^2 = 16(pi) cm^2 = 50.265 cm^2
area of grey triangle = (1/2)bh
The base is a diameter of the circle, so it is twice the radius.
The height is a radius.
area of grey triangle = (1/2)bh = 0.5 * 8 cm * 4 cm = 16 cm^2
white area = area of circle - grey area = 50.265 cm^2 - 16 cm^2 = 34.265 cm^2
p(white area) = (white area)/(total area of the circle)
p(white area) = (34.265 cm^2)/(50.265 cm^2)
p(white area) = 0.68
