Answer:
Step-by-step explanation:
<h3>7) The lengths of the tangent from an external point to a circle are equal.</h3>
2x - 1 = x + 10
2x = x + 10 + 1
2x = x + 11
2x -x = 11

8) Radius : XC
Chord: CB
Diameter : AB
Name of the circle: X {a circle is named by its center}
Answer:
Step-by-step explanation:
4x10=40
7x10=70
6x10=60
10x10=100
8x10=80
4x14=56
5x16=80
40+70+60+100+80+56+80= $486
Answer:
Angle 4 and Angle 5 are congruent.
Step-by-step explanation:
Answer:
It is called the constant ratio.
♥ Lets solve this:
(7*10^5)^2(7*10^5)^2
Starting with 10^5
10*10*10*10*10
We get <span>100000
<span>Now we have 7*100000
Solve for that:
We get </span></span><span>700000
Now we have </span><span>700000^2
Solve for that
We get </span><span>490000000000
and in Scientific notation that is
4.9*10^11</span>
