Answer:
Therefore no of apples in that group is 18
Step-by-step explanation:
Given:
No. of apples = 36
No. of pears = 20
Also it is given that grocer arranges the fruit into groups that have the same ratio of apples to pears as the whole collection of fruit.
first we find the ratio of apples and pears in whole collection which is given below
No. of apples/No. of pears = 36/20 = 9/5
Now its a problem of ratio
It is given that no of pear in one group is 10
Let the no of apples in that group be X
According to the question
No. of apples in whole collection/ No. of pear in whole collection = No. of apples in the group/ No. of pears in the group -------------> A
9/5 =X/10
=> X = (9*10)/5 = 18
Therefore no of apples in that group is 18.
Answer:
Step-by-step explanation:
You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.
Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD
The law of cosine is
CD^2=BC^2+BD^2-2(BC)(BD)cos DBC
Plug in what we know
CD^2=18^2+12.1^2-2(18)(12.1)cos 56
CD^2≈228.8387
Find the square root to isolate CD.
CD≈15.1
