Judging by the model I would assume that ΔDBC is congruent to ΔDBA.
Thus, line CD should be congruent to line AD as well, which the solution should be line CD=13 units.
So first find out how many can be done in 1 minute.
In an equation it would be 3x=42
Divide by 3
x=14
So 14 pushups can be done in 1 minute (congratulations to this person I can barely do one haha)
So now you multiply what you can do in 1 minute by 5 minutes.
14x5= 70 pushups
1) 210/2000=10.5%
2) What percentage of 64.99 is 45.49?
45.49/64.99=.699
.699=69.9%
Answer:
when they don't have the same proportion.
Step-by-step explanation:
To find the volume of a cylinder it's
πr² x height.
So π x 10² x 10 would be the equation.
I would do it but I don't have a scientific calculator on me.
