The fraction 78/10,000 as a decimal would be 0.0078.
Answer:
x=0
Step-by-step explanation:
y=-5x -6
10x + 2y = -12
Substitute y into the equation:
Use distributive property
Add like terms
Add 12 to both sides of the equation
divide each side by 0
Answer:
Centre is 
Radius is 
Step-by-step explanation:
The general equation for a circle is written in the form 
, where 
is the centre of the circle, and 
is the radius.
For your circle, 
, we can compare it with the general equation to find the centre and radius.
Therefore, 
, 
and 
.
Centre at which is .
Answer:
Point, Line, and Plane
Step-by-step explanation:
The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.
You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.
Answer: Area = 26π + 20 cm²
<u>Step-by-step explanation:</u>
There are 2 large semicircles = 1 large circle
There are 2 small semicircles = 1 small circle
There is 1 rectangle.
Find the Area of each shape above and then find their sum.
1) Large Circle: A = πr², d = 10 --> r = 10/2 = 5
A = π(5)²
= 25π
2) Small Circle: A = πr² , d = 2 --> r = 2/2 = 1
A = π(1)²
= π
3) Rectangle: A = length × width, L = 10 w = 2
A = 10 × 2
= 20
Total = Large + Small + Rectangle
= 25π + π + 20
= 26π + 20
