I knew that 9 plus 2 equals 11 so I add 5+1+1 which equals 7. Then I add the one which equals 71
10.5^2 + 20.8^2 = 110.25 + 432.64 = 542.89
23.3^2 = 542.89
Right triangle
------------------------
20.1^2 = 524.41
6^2 + 20.1^2 = 36 + 404.01 = 440.01
Not a right triangle
Answer:
Step-by-step explanation:
1 Hour = 60 minutes
60 + 60 = 120 minutes
120 minutes = 2 hours
Add 10 minutes
2 hours 10 minutes = 130 minutes
(x-3)=-3x+25
Because we know that y=x-3 so we put that in place of y in the equation
Answer:
Speed is distance divided by time, <u>Answer </u>750cm/h
Step-by-step explanation:
First we need to start by changing Meters to Centimeters
We know that 1 meter is = 100 centimeters
So 100x180= Distance traveled in Centimeters
18000=Distance traveled in Centimeters
Distance is 18000cm
Time is 24hr
Distance/Time= Speed
18000/24= Speed
Speed = 750cm/h
