50 represents the red candies.
2 represents the other half of candies.
x represents the total amount of candies.
Hope this helps!
Answer:
Using the calculator angle whose cos is 0.9511 is 18 degrees
Sine of the complementary angle = 0.9511 also
Step-by-step explanation:
The sine of the complementary angle( which is 90-18 = 72 degrees) is same value 0.9511
Circumference is <span>πd</span> where d is the diameter. You can derive this to isolate diameter by dividing both sides by π.
<span>D=<span>Cπ</span></span>. Now just plug the numbers for your variables.
<span>D=<span>75.363.14</span></span>
<span>D=24</span>
The diameter is 24 yards.
<span> A ⊂ B means all of A is in B
but then it says </span><span>A ∩ B = θ meaning they have nothing in common, ie, none of A is in B or vice versa
A must be the empty set for both these conditions to hold. B could be anything you want. B could be empty, or it could not be. It's impossible to tell.
For certain, A must be empty. Which is why the answer is choice C</span>
