Answer:
The distance between 2 points on a graph is given as:
root over of ((x2-x1)^2 + (y2-y1)^2)
using this formula we have,
root over of ((5-(-3))^2 + (1-(-4))^2
=root over of (64+25)= 9.43
Ans: the distance between A and b is 9.43 units.
Step-by-step explanation:
$20/hr carpenter pay
$25/hr blacksmith pay
Let c = hours working carpentry
Let b = hours working as blacksmith
c + b = 30 {equation 1}
20c + 25b = 690 {equation 2}
In equation 1 solve for one variable in terms of the other.
c = 30-b
Substitute that into equation 2:
20(30-b) + 25b = 690
600 - 20b + 25b = 690
5b = 90
b = 90/5
b = 18 hours working as a blacksmith
c = 30-b = 30-18 = 12 hours as a carpenter
You were right 24 is the answer. :)
