Answer:
(sin x)^2*(sec x) is positive in QII
Step-by-step explanation:
(sin x)^2 is always 0 or positive. Here x lies in QII.
sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.
In summary, (sin x)^2*(sec x) is positive in QII
3 parts blue and 2 parts red equals 5 parts. 40 pints divided by 5 parts equals 8. So 3 parts blue x 8 =24 parts blue. 2 parts red is 16 and 24 plus 16 does equal 40

Answer:
12/7 bag of flour is required to make 3 batches of cookies
Step-by-step explanation:
From the question;
2/7 bag of flour makes 1/2 of a batch of cookies
x bag of flour will make 3 batches of cookies
Mathematically, we cross multiply
2/7 * 3 = 1/2 * x
6/7 = x/2
2 * 6 = 7 * x
12 = 7x
x = 12/7 bag of flour
