9. This is actually the easiest you take both the mass and volume and divide them :) which would be 500g<span>÷25cm^3=20g/cm3 </span>

The ones I didn't answer I am not sure about and don't wanna give you any wrong answers :) Hope I helped though!
Answer:
B. Vertical angles are congruent
Step-by-step explanation:
The instructions are to prove that ∠ANR and ∠VNE are congruent, and ∠ANR and ∠VNE are vertical angles.
I hope this helps :)
Answer: cube
Step-by-step explanation:
Think of a box .... it has 4 sides, a top, and a bottom = 6 total sides
Which of the following statements are true for a rhombus? It has two pairs of parallel sides. It has two pairs of equal sides. It has only two pairs of equal sides. Two of its angles are at right angles. Its diagonals bisect each other at right angles. Its diagonals are equal and perpendicular. It has all its sides of equal lengths. It is a parallelogram. It is a quadrilateral. It can be a square. It is a square.
Bank A: 11.5% of $8,000 =
Bank B: 12.25% of $8,000 =
He saves $980 - $920 = $60
If I recall correctly, the slope-intercept form is y=mx+c or y=Mx+b
c is always the y-intercept of the graph, being the point where the line crosses the y axis. In this case:
c= -1
To get the slope, we can use the following equation:
m=(y2-y1)/(x2-x1)
All we need to do is substitute in two sets of coordinates. In this case we will use the coordinates highlighted with the bold points:
(1;2)
(-1;-4)
Now we will place the coordinates into the equation, making sure to correspond its x value to its y value:
m=(-4-2)/(-1-1)
m=3
Therefore the equation is y=3x-1
