Answer:
58×.20=11.60 58.00+11.60= 69.60 your total cost is 69.60 to leave your tip on top of the bill
Step-by-step explanation:
any time you want a percentage of a number you take your number in this case 58.00 times whatever percentage in this case 20% so 58×.20 =11.60 then you take your total plus the amount you come up with for the tip 58.00+11.60=69.60
Well you would reverse the equation when it is solved, ie:
d = 1/2 + 3/4
and it would be the last answer, or 1.25 miles
Answer:
y = 
+ 2
Step-by-step explanation:
The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:
Slope(s) = Change in y ÷ change in x
s = 
= 3
The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = 
Reason: The product of slopes of lines perpendicular to each other have to be -1
So the slope of the perpendicular line that passes through (-6,4) is
As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x
Taking another point (x,y) on the line,
= 
= 
y - 4 = x - 2
y = x + 2
Answer:
79 minutes
Step-by-step explanation:
A plane is travelling at 180 meters per seconds
Convert to km/hr
180× 18/5
= 648 km/hr
Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is
= 1/648 × 800
= 1 hour 19 minutes
Conver the time to full minutes
60 minutes = 1 hour
= 60+19
= 79 minutes
Hence the minutes required for the plane to travel 800km is 79 minutes
