For the answer to the question above, just <span>use similar triangles.
</span>Here's the equations that I used.
<span>t/h = (x + t) / r </span>
<span>x + t = rt / h </span>
<span>x = rt / h - t
I hope my answer helped you in your problem, Have a nice day</span>
Answer:
X=11
Step-by-step explanation:
(10x+30)=140
-30 both sides
10x=110
Divide 10 both sides
X=11
Answer:
9
Step-by-step explanation:

A. C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.
B. P(13,10)= 13! =13! =13·12·11·10·9·8·7·6·5·4.
(13−10)! 3!
C. f there is exactly one woman chosen, this is possible in C(10, 9)C(3, 1) =
10! 3!
9!1! 1!2!
10! 3!
8!2! 2!1!
10! 3!
7!3! 3!0!
= 10 · 3 = 30 ways; two women chosen — in C(10,8)C(3,2) =
= 45·3 = 135 ways; three women chosen — in C(10, 7)C(3, 3) =
= 10·9·8 ·1 = 120 ways. Altogether there are 30+135+120 = 285
1·2·3
