In general:
For any 3 numbers a, b, and c≠0,
If a=b then a.c=b.c (a times c = b times c)
This is called the "multiplication property"
In or case, a=|MN|, b=|2AB|, c=3
MN=2AB so 3.MN=3.2ab, so 3MN=6AB
Answer: Multiplication property.
Angle at centre = 2 x angle at circumference.
since angle BDC is 92 degrees, angle BAC will be 92/2 degrees
Answer:
The answer to your question is 2. (-1/2, 13/2)
Step-by-step explanation:
Equation 1 9x + 5y = 28
Equation 2 5x + 9y = 56
Process
- Solve by Elimination
- Multiply equation 1 by 5 and equation 2 by -9
5(9x + 5y = 28)
-9(5x + 9y = 56)
45x + 25y = 140
-45x - 81y = -504
0 -56y = -364
y = -364/-56
y = 13/2 = 6.5
- Find x
9x + 5(13/2) = 28
9x + 65/2 = 28
9x = 28 - 65/2
9x = -9/2
x = (-9/2)/9
x = -1/2
We know that
<span>the probability of the Galaxy team winning is 22%------> 0.22
</span>the probability of the Galaxy team losing is 100%-22%----> 78%-----> 0.78
<span>the probability of the Komets team winning is 47%------> 0.47
</span>the probability of the Komets team losing is 100%-47%----> 53%-----> 0.53
therefore
<span>the probability of the comets losing their race and the galaxy winning theirs is
0.53*0.22=0.1166------> 11.66%
the answer is
11.66%</span>
12 / 7 * 5 + 20 - 5
7 * 5 = 35
35 + 20 = 45
45 - 5 = 40
12 / 40 = 0.3 or 3/10
Your answer is 0.3 or 3/10
