Answer:
7.A (5,1)
B(5,7)
8. D (0,6)
Step-by-step explanation:
7. One vertex is at (5,4)
Move 3 units either direction in x
(5-3,4) = (2,4)
(5+3,4) = (8,4)
Or move 3 units in the y direction
(5,4+3) = (5,7)
(5,4-3) = (5,1)
If x is less than 2 or greater than 8 it is too far from the one vertex we are given
If y is less than 1 or greater than 7 it is too far away from the one vertex we are given
C cannot be a vertex since y =9
D is not a vertex since the point is (2,6) and not (2,4) which we know is 3 units away
E is not a vertex since the point is (2,1) and not (2,4) which we know is 3 units away
8. The center is (0,0)
The points have to add to a radius of 6
r^2 = 36
The sum of the x^2 and y^2 = 36
3^2 +0^2 = 9
4^2 +2^2 = 16+4 = 20
5^2 +3^2 = 25+9 = 34
0^2+6^2 =36 yes for D
4^2 +4^2 =16+16 = 32
1^2+5^2 = 26
Answer:
The length of the other piece is 38 inch.
Step-by-step explanation:
Given:
A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.
Now, to find the length of the other piece.
Let the length of the other piece be 
.
And the length of one piece be 
.
The total length of the pipe = 
According to question:
⇒
<em>Dividing both sides by 5 we get:</em>
⇒
Therefore, the length of the other piece is 38 inch.
Answer:
127 degrees
Step-by-step explanation:
The angles inside a polygon are equal to 180(n-2), therefore a hexagon will be 180(6-2)= 720degrees. Therefore,
112+133+128+100+120+x=720
Solve for X
x= 720-593 = 127 degrees
Kilogram is an SI unit for mass.
Ounce and pound refer to American system for measuring things, and decakilogram is not the "basic" unit, but kilogram is.
Answer:
b
Step-by-step explanation:
A^2 + B^2 = C^2 - Right Triangle Formula
8^2 + 7^2 = 6^2 - Plug it into the formula
64 + 49 = 36 - Solve
64 = 85 - Add B and C
21 - your answer
Hopefully this helps.
