We have 112.5 = 225/2; cos112.5 < 0 because 90 < 112.5 < 180;
cos 112.5 = cos(225/2);
We use the trigonometric formula: cos(x/2) = -

;
Then, cos(225/2) = -

;
We have the formula: cos(270 - x) = -sinx (because cos(a-b) = cosacosb + sinasinb);
Then, cos225 = cos(270-45) = -sin45 = -

Finally, cos112.5 = -
The cost of the brand less than 6 bags is less than 11.94
<h3>Functions and equations</h3>
If the cost y of a brand can be represented by the equation y=1.99x
where
- x represents the number of bags.
For a brand that costs less than 6 bags, we will substitute x = 6 into the function
y = 1.99(6)
y = 11.94
Hence the cost of the brand less than 6 bags is less than 11.94

The <em>correct answer</em> is:
12 bouquets, each having 6 red roses, 5 pink roses, and 4 yellow roses.
Explanation:
To find the number of bouquets we can make, we find the GCF (greatest common factor) of the three numbers, 72, 60 and 48. To do this, we find the prime factorization of each:

We look for factors that all 3 numbers have in common. These factors are 2, 2 and 3; 2(2)(3)=12, so we can make 12 bouquets.
72/12 = 6; this means we use 6 red roses in each bouquet.
60/12 = 5; this means we use 5 pink roses in each bouquet.
48/12 = 4; this means we use 4 yellow roses in each bouquet.
Hello,
h=k*w/p; if w=4,and p=6 then h=2
2=k*4/6==>k=2*6/4==>k=3
