Answer:

LCM(1,2,12,30,84,165)=2^2*3*5*7*11*1=4620

Step-by-step explanation:

To find the LCM of 1,2,12,30,84,165 you must first find the prime factors of 12,30,84 and 165

12| 2               30| 2             84| 2                   165| 3

6 | 2               15 | 3             42| 2                   55 | 5

3 | 3                5 | 5              21 | 3                   11 | 11

1                       1                   7 | 7                     1

                                            1

12=2^2*3     30=2*3*5       84=2^2*3*7         165=3*5*11

Now we look for common and uncommon factors with their greatest exponent

LCM(1,2,12,30,84,165)

Common factors with their greatest exponent: 2^2*3*5

Uncommon factors with their greatest exponent: 7*11*1

LCM(1,2,12,30,84,165)=2^2*3*5*7*11*1=4620

Lynn measured the length of her front yard by counting her strides. The yard measured 18.5 feet long. Emily measured the same ya
Shalnov [3]

Answer:

8.11%

Step-by-step explanation:

We need to find the percentage error. We can follow the formula shown below:

PE=\frac{New-Orig}{Orig}*100

Where

PE is the Percentage Error

New is the newest measure (given as 20 feet)

Orig is the original, or first, measure (given as 18.5)

Substituting and finding the PE:

PE=\frac{New-Orig}{Orig}*100\\PE=\frac{20-18.5}{18.5}*100\\PE=\frac{1.5}{18.5}*100\\PE=8.11

Tagging the percentage , percent error is about 8.11%
