How can you tell when the LCM of two numbers will equal one of the numbers or equal the product of the numbers
Vladimir79 [104]

When one number will divide exactly into the other one then the other one will be the LCM. For example the LCM of 4 and 8 = 8 .

When they do not divide as above then the product of the numbers may be the LCM. For example the LCM of 3 and 4 = 3*4  = 12.  

The product is not always the LCM.  It might be a lower number . For example the LCM of 4  and 6 is not  24  but 12.  ( 24 / 2).

A construction company purchased some equipment costing $300,000. The value of the equipment depreciates
goldfiish [28.3K]

Answer:

11.9\ years  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

V=P(1-r)^{x}  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

P=\$300,000\\r=14\%=14/100=0.14\\V=\$50,000

substitute the values and solve for x

50,000=300,000(1-0.14)^{x}  

(50,000/300,000)=(0.86)^{x}  

(5/30)=(0.86)^{x}  

Apply log both sides

log(5/30)=(x)log(0.86)  

x=log(5/30)/log(0.86)  

x=11.9\ years
