Answer:
72
Step-by-step explanation:
cross out 4 from left to right, right to left, you get 71 and 73, the mean of those two numbers is 72
Answer:
75 seconds to run 180 meters
Step-by-step explanation:
(180m) / (2.4m/s) = 75 seconds
75 seconds to run 180 meters, but if we take into consideration the initial 39 seconds, then the total time it took to run (75s + 39s) was 114 seconds.
The question didn't explicitly ask the total time it took, but the time it took to run 180 meters.
Answer is 9/5
You can count the rise/run on the graph or use slope formula (y2-y1) over (x2 -x1)
5-(-4) over 3-(-2) = 9/5
This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.
Answer:
The angles of both triangles are the same
The two triangles are both acute because they all have acute angles
