You will need to set equations to solve for x and y coordinate.
(2+x)/2=4
2+x=8
x=6
(6+y)/2=10
6+y=20
y=14
The answer is A. (6,14)
If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g

Ahh! Finally done with this, if you have any doubt just do ask me :)
Answer:
Triangle RED ≈ Triangle BUL
By-
SAS Congruencey
Beacause-
RE = BU (S)
ang RDE = ang BLU (A)
RD = BL (S)
(All the info for the relationship is given in the diagram itself)
Thus it's SAS Congruencey
OK so where is the weekly math homework!?
Answer:
rational
Step-by-step explanation:
the equation above would be -10 making it an integer
integers are rational
