Here is some thoughts on this:
cos 57 = sin (90-57) = sin 33
so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1
2 cos 60 = 2 * 1/2 = 1
so the last 2 parts work out to 0
now we have to find cos 70 / sin 20
sin 20 = cos 70 so this comes to 1
so finally the answer is 1
Answer: 20 strawberries
1 litre of orange juice
500ml yogurt
2
Step-by-step explanation:
Based on the recipe, the average for 1 smoothie, we need buy 5 strawberries, 1/4 litre of orange juice, 125ml yogurt, 1/2 banana
Thus, for 4 smoothies, we need the average quantity for 1 smoothie multi with 4
- 5*4 = 20 strawberries
- 1/4 litre *4 = 1 litre of orange juice
- 125ml yogurt * 4 = 500ml yogurt
-1/2 of banana * 4= 2 banan
Answer:
vertex is (-4,-6)
Step-by-step explanation:
put x+4=0
x=-4
when x=-4
f(x)=-6
Answer:
5/18
Step-by-step explanation:
6 and 3/4 = (6*4+3)/4 = 27/4. 1 and 7/8 = (8+7)/8 = 15/8. (15/8)/(27/4) = (15/8) * (4/27) = 60/216 = 30/108 = 15/54 = 5/18
48 cookies from 2 cups of flour, rate = 48 cookies / 2 cups = 24 cookies / cup
60 cookies from 3 cups of flour, rate = 60 cookies / 3 cups = 20 cookies / cup
If the rates were proportional, the rates would have the same answers.
Therefore the rates are not proportional.
