Answer:
D=100
R=50
Step-by-step explanation:
Diameter can be found by dividing the circumference by pi (314/3.14=100). Dividing the diameter in halve is used to find the radius (100/2=50).
I don't really know if the question is complete but...
y = x -10 can be a solution
so y would be -7 when x is 3
Answer:



Step-by-step explanation:
First, let's look at the largest triangle (two smaller triangles are combined) to solve for
. Since the sum of the angles in a triangle adds up to
, we can write the equation:



Looking at the smaller triangle on the left,
(exterior angle) is the sum of the two opposite interior angles of the triangle on the left:


Since
is the exterior angle of the triangle on the right, it is equivalent to the sum of the opposite interior angles of that triangle:



Hope this helps :)
Answer:
994 :)
Step-by-step explanation:
PEMDAS
(8+2)^3 - 6
(10)^3 = 10 x 10 x 10
1,000 - 6
994
Answer:
$5829.57
Step-by-step explanation:
Annually compounding interest formula: 
5000(1+.0525)^3
5829.567266
which rounds to: 5829.57
