Find the distance between each pair of points. (-5, -3) and (-5, -6)
Aloiza [94]

Answer:

• Formular for length:

length =  \sqrt{ {(x _{1}  - x  _{2}) }^{2}  +  {(y_{1} - y_{2})}^{2} }

• from points given, x1 is -5, x2 is -5, y1 is -3 and y2 is -6:

• substitute:

length =  \sqrt{ { \{ - 5 - ( - 5) \}}^{2}  +  { \{ - 3 - ( - 6) \}}^{2} }  \\  \\ length =  \sqrt{ {0}^{2} +  {3}^{2}  }  \\  \\ length =  \sqrt{ {3}^{2} }  \\  \\ { \boxed{ \boxed{ \:  \: length = 3 \: units \:  \: }}}

1/2 plus 1/5 plus 2/6 plus 1/8
mamaluj [8]

Need to find the common denominator for the fractions which is 120.

Multiply by 60 for 1/6 . Multiply by 24 for 1/5. Multiply by 20 for 2/6. Multiply by 15 for 1/8.

(1)(60)/(2)(60)+(1)(24)/)5)(24)+(2)(20)/(6)(20)+(1)(15)+(8)(15)

= 60/120+18/120+40/120+15/120

= 78/120+55/120

= 139/120 or in mixed number : 1 19/120

Answer: 139/120 , 1 19/120

if employee a logged 120 hours of travel in four years and employee b logged of travel at a 20% higher rate how many more hours
Gnoma [55]
First we need to find the rate of logging for employee A per year. To do this, the number of hours can be divided by the number of years to find out how many hours of travel they log per year.

120 ÷ 4 = 30. Employee A logs roughly 30 hours of travel per year.

To find a percentage increase of 20%, you need to multiply by 1.2. 
30 x 1.2 = 36. 
Therefore, Employee B logs roughly 36 hours of travel per year.

To find out how many hours of travel Employee B logs after 1.5 years, we simply need to multiply 36 by 1.5, which equals 54.

To find out how many hours of travel Employee A logs after 1.5 years, we simply need to multiply 30 by 1.5, which equals 45.

Finally, we need to find out how many MORE hours Employee B logged after 1.5 years compared to Employee A. To do this, we simply need to do 54 - 45 = 9 hours.

Working = (((120/4) x 1.2) x 1.5) - (120/4 x 1.5)
Answer = 9 hours.
