Answer:
D) 3x + y = 5 and 2x -3y = 7
Step-by-step explanation:
You can plug in the x and y values into the equations, and see if they work. In this case, 3x + y = 5 and 2x -3y = 7 both satisfy (2, -1).
Answer:
See explanations below
Step-by-step explanation:
Volume of the sphere is expressed as;
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 3³
V = 4/3 * 3.14 * 27
V = 4 * 3.14 * 9
V = 113.04cube units
For the secind sphere;
diameter = 12
radius = 12/2 = 6
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 6³
V = 4/3 * 3.14 * 216
V = 4 * 3.14 * 72
V = 904.32cube units
For this case we have that the surface area of the prism is given by:
Where:
: Is the lateral area
B: It is the area of the base
Where:
Q: It is the perimeter of the base
h: It's the height
On the other hand:
So, we have:
Answer:
Answer: 6.66 repeated
Step-by-step explanation:
10 divided by 1.5 will give you 6.66 repeated
