The answer is actually A. Sides are named by their angles.
Answer:
153.3852
Step-by-step explanation:
After the decimal, you count the places. 3 is in the ones place, 8 in the tenths, 5 in the hundreths, and 1 in the thousandths. The thousandths place is what we are rounding, so we look at the next number, 9, which tells us to round the 1 up to 2
Answer:
1/3

Answer:
Therefore, ' 19 ' smaller lawn mover and '11' larger lawn mover were sold.
Step-by-step explanation:
Given:
let the smaller lawn mover be 'x'
let the larger lawn mower be 'y'
According to condition total mover will be
................( 1 )
and total cost will be given as
................( 2 )
To Find:
x =? and y =?
Solution:
Substituting equation 1 in equation 2 we get
![249.99(30-y)+329.99y=8379.7\\7499.7-249.99y+329.99y=8379.7\\80y=880\\\\y=\dfrac{880}{80}\\\\y=11](https://tex.z-dn.net/?f=249.99%2830-y%29%2B329.99y%3D8379.7%5C%5C7499.7-249.99y%2B329.99y%3D8379.7%5C%5C80y%3D880%5C%5C%5C%5Cy%3D%5Cdfrac%7B880%7D%7B80%7D%5C%5C%5C%5Cy%3D11)
Substituting ' y 'in ( 1 ) we get
![x=30-11=19\\x=19](https://tex.z-dn.net/?f=x%3D30-11%3D19%5C%5Cx%3D19)
Therefore, ' 19 ' smaller lawn mover and '11' larger lawn mover were sold.
Answer:
The scale factor is 4
Step-by-step explanation:
This question requires an attachment; I'll answer this question using the attached figure
From the attachment
<em>Length OA = 3 units</em>
<em>Length OA' = 3 units + 9 units</em>
<em>Length OA' = 12 units </em>
<em></em>
Scale Factor is calculated as follows;
![Scale\ Factor = \frac{New\ Side}{Original\ Side}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7BNew%5C%20Side%7D%7BOriginal%5C%20Side%7D)
Given that the original shape is ABC, the original side will be OA
Hence, Original Side = 3 units
New Side = OA' = 12 units
The formula becomes
![Scale\ Factor = \frac{12\ units}{3\ units}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7B12%5C%20units%7D%7B3%5C%20units%7D)
![Scale\ Factor = 4](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%204)
<em>Hence, the scale factor is 4</em>
