Atree cast a 25-foot shadow. at the same time of the day, a 6-foot man standing near the tree casts 9-foot shadow. what is the height of the tree, to the nearest foot?

The height of the tree is 16.67 feet.

Step-by-step explanation:

Refering the figure, let the height be "x" feet.

It is evident that triangles ABC and triangle EDC are similar.

(as both man and tree are perpendicular to the ground)

thus,

hence,

Thus, .

here

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
