Answer:
A x =30
Step-by-step explanation:
(y+x) and (y-x) make a straight line so they add to 180 degrees
(y+x) + (y-x) = 180
Combine like terms
y+y+x-x=180
2y=180
Divide by 2
2y/2 = 180/2
y= 90
(y+x) and 2x make a straight line so they add to 180 degrees
y+x+2x = 180
Combine like terms
y+3x = 180
Since we know y we can substitute it in
90+3x = 180
Subtract 90 from each side
90-90+3x= 180-90
3x = 90
Divide by 3
3x/3 = 90/3
x= 30
Answer:
The distance between the points (6,-4) and (0,5) = 10.82 units
Step-by-step explanation:
<u>Distance formula</u>
Length of a line segment with end points (x1, y1) and (x2, y2) is given by,
Distance = √[(x2 - x1)² + (y2 - y1)²]
<u>To find the distance between given points</u>
Here, (x1, y1) = (6, -4) and (x2, y2) = (0, 5)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(0 - 6)² + (5 - -4)²]
=√[(-6)² + (9)²]
= √[36 + 81]
= √[117
= 10.82
The distance between the points (6,-4) and (0,5) = 10.82 units
Hope this helps!!!!!!!!
If t is the amount of time she used it, then it lost t*(5/min) percentage points; then she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.
This means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.
This means that she used her phone for 10 minutes and charged it for 20 minutes.
