D. 3 to 5
This is because if you simplify the ratio by dividing each number in the ratio by 4, therefore for every group of 5 birds 3 of them are parrots
First, find the simplified ratio of the given ratio:
Number of pirates: 22
Number of ships: 2
Divide 22 with 2 to find the ratio: 22/2 = 11
For every ship there is, there will be 11 pirates.
Now, find the ratio for the other questions:
IF there are 5 ships: 5 x 11 = 55
If there are 5 ships, there will be 55 pirates.
If there are 11 ships: 11 x 11 = 121
If there are 11 ships, there will be 121 pirates.

Answer:
8sin(x)cos³(x)
Step-by-step explanation:
sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=
= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=
= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)
Answer:
50.6
Step-by-step explanation:
The perimeter of the circle is 12.56 because we take 1/2 of 8 (the length of the short side of the rectangle) and multiply that by pie (or 3.14). Now that we know that the perimeter of the circle is 12.56 we add that to 8 (short side of the rectangle) and we add that to 15 twice (which is 30)
