If a 15 ft tall adult giraffe casts a 18 ft long shadow, then how long is the shadow that a 5 ft tall bird bath casts?

Step-by-step explanation:

its a ratio and proportion:

 15 ft. tall giraffe       =     5 ft. tall bird    

    18 ft. shadow                 x shadow

15 (x) = 18 (5)

x = 90 / 15

x = 6 ft. long shadow

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
