Answer:
D 12
Step-by-step explanation:
The product of the lengths of the segments of one chord equal the product of the segments of the other.
x*4 = 6*8
4x = 48
Divide each side by 4
4x/4 = 48/4
x = 12
I hope this helps you
x^2-4x-12
x -6
x +4
(x-6)(x+4)
Here's the work and the answer. I hope this helps.
Given the table below which lists the masses and volumes of several pieces of the same type of metal.<span>
From the table the ratio of the mass to the volume of the metal of mass 34.932 is 34.932 / 4.1 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 47.712 is 47.712 / 5.6 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 61.344 is 61.344 / 7.2 = 8.52
</span><span><span>the ratio of the mass to the volume of the metal of mass 99.684 is 99.684 / 11.7 = 8.52
</span>MASS (grams) VOLUME (cubic cm.)
34.932 4.1
47.712 5.6
61.344 7.2
99.684 11.7</span>
Since the ratio of the various masses to the volume of the metals is the same, so there is a relationship between the mass and the volume of the piece of metal.
If the volume of a piece of metal is 15.3 cubic cm, then the mass of the metal is given by 15.3 * 8.52 = 130.356 grams.
Answer:
75 = GXD
Step-by-step explanation:
We know that CXE is a straight line
A straight line is 180 degrees
CXE = CXG + GXD +DXE
Substituting what we know
180 = 85+ GXD + 20
Combine like terms
180 = 105+GXD
Subtract 105 from each side
180-105 = 105-105 +GXD
75 = GXD
