Answer:
7a²/16
Step-by-step explanation:
Area of the triangle PTS
½ × a × a
a²/2
Length of PS:
sqrt(a² + a²)
asqrt(2)
Length of MS:
¼asqrt(2)
Triangles MCS and TPS are similar
With sides in the ratio:
¼asqrt(2) : a
sqrt(2)/4 : 1
Area of triangle SMC:
A/(a²/2) = [(sqrt(2)/4)]²
2A/a² = 1/8
A = a²/16
Area of PTMC
= a²/2 - a²/16
= 7a²/16

Step-by-step explanation:
If it is a fair roulette, the probability to land on RED should be the same no matter what results are in the previous spin
a) 18/38
b) 18/38
c) Yes, I'm confident of the answers. Because it's fair and there is no change of RED numbers.
The answer is 24m^2 i just finished that test and that was the answer.<span />
Answer:
First of all, find x from the Pythagorean theorem 
, which c is the hypotenuse.
c=25 or x=25
Next, we have to figure out the value of y and z. So, you need to use inverse trigonometric functions.
arctan
degrees. arctan
degrees.
All in all, the values are
x=25
y=16.3
z=73.7
Hope this helps and have a nice day!
5c+10a=3570
c+a=512
...
a=512-c
so ...
5c + 10(512-c)=3570
