<h2>The chances of receiving two greens are 5/31.</h2>
<em>Given a bag containing four blue, three red, and five green marbles, the total result is:</em>
<em>Total number of balls = 4 + 3 + 5 = 12</em>
<em>If green is chosen first, the chances of picking a green are 5/12.</em>
<em>The probability that the second stone is green is 4/11 if it is picked and not replaced (4 greens remaining)</em>
<em>The chance of earning two greens is 5/12 4/11.</em>
<em>The chance of getting two greens is 20/132.</em>
<em>The chance of earning two greens is 5/31.</em>
<h3>
<em>As a result, the chance of getting two greens is 5/31.</em></h3>
Answer:
80°
Step-by-step explanation:
Let the angle be x then four times it's complement plus 60, that is
4(90 - x) + 60 ← is it's supplement
Supplementary angles sum to 180°
Sum the angle and it's supplement and equate to 180
x + 4(90 - x) + 60 = 180 ← distribute and simplify left side
x + 360 - 4x + 60 = 180
- 3x + 420 = 180 ( subtract 420 from both sides )
- 3x = - 240 ( divide both sides by - 3 )
x = 80
The required angle = x = 80°
supplement = 4(90 - 80) + 60 = 4 × 10 + 60 = 40 + 60 = 100°
Answer:
6.13
Step-by-step explanation:
Using Sine Law we know that
Using your figure let's assign sides and angles:
A=? B = 60° C = 70°
a = 5 b = ? c = x
If we put that into our formula:
Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?
Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°
∠A + ∠B + ∠C= 180°
∠A + 60° + 70° = 180°
∠A + 130° = 180°
∠A = 180° - 130°
∠A = 50°
Now we can use this to solve for x.
So the closest answer would be 6.13
You're so pointless ... duh XD
