Answer:
The street light is 20 feet tall.
Step-by-step explanation:
This question depends on a proportion. Keep your height of the object in one ratio and the length of the shadow in the other.
25/x = 75/60 Notice the height of the structure is on the left. The length of the shadow is on the right. Cross multiply
75x = 60 * 25 Combine the right
75x = 1500 Divide by 75
x = 1500/75
x = 20
The street light is 20 feet tall.

Answer:
B 3x: 51 = 3x+24: 85
Step-by-step explanation:
Since the triangles are similar
PS PQ
------- = -----------
PT PR
Substitute the values in
3x 3x+24
------- = -----------
51 85
3x: 51 = 3x+24: 85

Answer:
Step-by-step explanation:
First lets prime factorize each number
24 = 2 x 2 x 2 x 3
36 = 2 x 2 x 3 x 3
45 = 3 x 3 x 5
GCF = 3 (3 is the only common prime number factor in the 3 numbers)
LCM = 2 x 2 x 2 x 3 x 3 x 5
= 24 x 3 x 5
= 72 x 5
= 360
