We need only realize that 1(-8)(-6)=48 to see that C) is the only answer from those choices that can be an answer.
That solid figure that you are is a square.
It's a value you should probably memorize:
You can derive it using some trigonometric identities, other known values of cosine, and properties of the cosine function. For example, using the double angle identity for cosine:
If , then
and you probably know that , so
When we take the square root, we should take the positive root because whenever :
Answer:
40
Step-by-step explanation:
The bread is 90.
28% is cookie
Then 72 %is bread and cake
Sum of bread and cake is 360
1%is 5 so cookie is 140
If sell 40 bread. Bread left is 50. Cake left is 150
Then cookie must be left 100 because the ratio of the no 1 is =to 50
Then need to sell 40 cookie so the ratio will be
50:150:100= 1:3:2
1) 40
2)4.0
3)0.40
I believe I hope this helps!
