The formula for density is:
Mass/Volume, or in other terms, mass divided by volume.
So, lets look at our numbers:
We know our mass is 84 grams, and our volume is 12 cc. So, all we need to do is divide 84 by 12, which is 7.
So, the density is 7.
Answer:
A,B,C
Step-by-step explanation:
in these quadrilaterals, the diagonals bisect each other paralellogram, rectangle, rhombus, square
in these quadrilaterals, the diagonals are congruent rectangle, square, isosceles trapezoid
in these quadrilaterals, each of the diagonals bisects a pair of opposite angles rhombus, square
Answer:
Let (-18, -5) be (x1,y1)
(-19, -13) be (x2,y2)
slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8
Multiply both numbers by the same number.
Example 17/20 = 34/40
I multiplied both numbers by 2!

When the length of sides are given, you can use law of cosine to find the angles
Refer to this website for details

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25
