Answer:
As per the statement:
Shadow of tree = 10 ft
Shadow of boy = 2.5 ft
and
height of the boy = 5 ft
we have to find the height of the tree.
Since, the given triangles are similar their corresponding sides are in proportions
then;
Substitute the given values;
Multiply both sides by 5 we have;
Therefore, the height of the tree is , 20 ft
1/10*344
=344/10
=34.4
We will move the decimal to the left side in case of division.
Answer:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
Step-by-step explanation:
First we formulate the problem in equations:
Abel = 6 * Ben
Cale = Abel / 3
If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.
If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)
So, the ratio between all scores are the following:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
