AC = 9 m; BC = 16.16 m; BD = 28.27 m; CD = 12.12 m
<em>Find AC
</em>
AC = AB = 9 m
<em>Find BC</em>
∠BAC = 2π – 10π/7 = (14π – 10π)/7 = 4π/7
BC = <em>θr</em> = 4π/7 × 9 m = 16.16 m
<em>Find BD
</em>
∠BAD = π
BD = <em>θr</em> = π × 9 m = 28.27 m
<em>Find CD</em>
<em>C</em> = 2π<em>r
</em>
CD = <em>C</em> – BC – BD = 2π<em>r</em> – 4π<em>r</em>/7 – π<em>r</em> = (14π<em>r</em> – 4π<em>r</em> – 7π<em>r</em>)/7 = (3π/7)<em>r</em>
= (3π/7) ×9 m = 12.12 m
Answer:
Trillion is a 1 with 12 zeros after it, and it looks like this: 1,000,000,000,000.
Step-by-step explanation:
Answer:
26*25*24=15600 ways
Step-by-step explanation:
for the gold medal, there are 26 possible people that can win it.
for the silver medal, there are 25 possible people that can win it because someone already has the gold medal.
same for bronze. 24
then multiply the numbers and you will get 15600.
Answer:
x=14
Step-by-step explanation:
g(x) = 2(x − 4)
Let g(x) = 20
20 = 2(x − 4)
Divide each side by 2
20/2 = 2(x-4)/2
10 = x-4
Add 4 to each side
10+4 = x-4+4
14 =x
You get -40/54 when you multiply, then you simplify and get -20/27, which is the answer.
