0. Zero is zero. Moving a point 2 ft below deducts 2 from the original number(whatever it was). Moving a point 0 ft below deducts nothing so the answer is 0.
20=x/3-8
28=3x
3x/3 = 28/3
X= 28/3
Answer:
672m^2
Step-by-step explanation:
Area= lenght * breadth
Area = 28 * 24
Area = 672 m^2
Answer:
209 (Sorry if wrong)
Step-by-step explanation:
12x12=144
13x5=65
144+65=209
This question is incomplete, the complete question is;
Katie Ledecky swims the length of a 50m Olympic size pool in 25 seconds and swims the return trip to the starting position in 26 seconds. What are her average velocities during:
a) The first half of the swim?
b) The second half of the swim?
Answer:
a) her average velocities during the first half = 2 m/s
b) her average velocities during the second half = 1.923 m/s
Step-by-step explanation:
Given that;
displacement = 50 m
time taken t = 25 secs
a)
average velocity = displacement / time taken = 50 / 25 = 2 m/s
Therefore her average velocities during the first half = 2 m/s
b)
In the second half;
displacement = 50 m
time taken t = 26 secs
average velocity = displacement / time taken = 50 / 26 = 1.923 m/s
Therefore her average velocities during the second half = 1.923 m/s
