Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance= 
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ = (2-5)²+(4-(-3))²
PQ = (-3)²+7²
PQ= 9+49
PQ=58
So,the distance of PQ is
Find the total length in inches of one of the rolls:
15*12=180 inches.
Now multiply the length of one roll (180 inches) by 2 to find the total length:
180*2=360 inches.
Divide by the width of the strips to find the total number of strips:
360/9=40 strips
The answer to this is.9/10

Answer:
$79.7
Step-by-step explanation:
Total income is $(234.8 + 64 + 20) = $318.8
Now, One-fourth of her income is budgeted for car insurance i.e. 
dollars.
And, 1/10 of her income is budgeted for gasoline i.e. 
dollars.
Finally, 2/5 of her income is budgeted for savings i.e. 
dollars.
Therefore, the remaining amount of her income = $(318.8 - 79.7 - 31.88 - 127.52) = $79.7 is left for her spending. (Answer)
