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

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

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%
