Answer: 3:4
Step-by-step explanation: There are 6 red grapes and 8 blueberries. So this would make the ratio 6:8 normally. You want to find the biggest number that goes into 6 and 8, which is 2. You divide both by 2 and get 3:4, since both don't have a big number that goes into both, your answer is 3:4

Answer:

Step-by-step explanation:
In this problem, we have:
H = 452 m is the height of the Petronas tower
h = 1.75 m is the height of the woman
d = 120 m is the distance between the woman and the base of the tower
First of all, we notice that we want to find the angle of elevation between the woman's hat the top of the tower; this means that we have consider the difference between the height of the tower and the height of the woman, so

Now we notice that
and
are the two sides of a right triangle, in which the angle of elevation is
. Therefore, we can write the following relationship:

since
H' represents the side of the triangle opposite to 
d represents the side of the triangle adjacent to 
Solving the equation for
, we find the angle of elevation:

Answer: 2 1/2 1 1/6 2 2/5
