Answer:
67%
Step-by-step explanation:
0.67 --> just move the decimal twice
Step-by-step explanation:
x + y = 25
x - y = 13
x.y = ?
x + y = 25
y = 25 - x
x - y = 13
x - 25 + x = 13
2x = 13 + 25
2x = 38
x = 38/2
x = 19
y = 25 - x
y = 25 - 19
y = 6
(x, y) = (19,6)
So, find their product!!
= x.y
= 19 × 6
= 114
<span>Cosine and Sine are related by the formula cos(x)= sin(x+90). Setting x+90 equal to 75 results in x=-15, Therefore, cos(-15) = sin (75). Since cos is an even function, cos(15)=cos(-15)= sin(75).</span>
Therefore the answer would be C.
Answer:
poverty
Step-by-step explanation:
lack of workers makes no sense bcs the population was only increasing
limited recreational options don't make any sense either bcS that is not affected by population
