Answer:
Step-by-step explanation:
We make
an integer that represents the Sharks' wins,
represent the losses, and
represent the ties.
We know that
,
, and
.
We subtract the first two equations, to get
. If we plug this into the third equation, we get
.
We plug this into the first equation and get
. Simplifying, we find that
.
Your answer would be 7.94 units.
First we must note that a perpendicular bisector halves the side it is bisecting, so FA = FB. This then allows us to say that FA = 9, as 18 ÷ 2 = 9.
Now that we know FA = 90, we can see the right triangle with a hypotenuse AD, which is 12, and a leg FA, which is 9.
This then allows us to use Pythagoras's Theorem to find a leg of a right triangle, c² - b² = a², so we can do:
12² - 9² = 144 - 81 = 63
√63 = 7.93725, which is 7.94 to the nearest hundredth.
I hope this helps!

Step-by-step explanation:
Answer:
20
Step-by-step explanation:
19+76+12+53+23=183$
she had 325
325-183= 140
therefor 140$- 120$ would leave Tasha with 20
