Answer: It will take the Dolphin 2 hours to swim 40 miles. The penguin will take 8 hours. The swordfish will take 2/3 of an hour, that is 40 minutes, to travel 40 miles.
Step-by-step explanation: Divide the given distance by the unit rate given:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour
This is the reverse of the process described in the question.
If the dolphin takes 2 hours to swim 40 miles, what is its unit rate? x ÷ y = R 40 miles÷2 hours= 20 mph.
40 miles ÷ 2/3 hour
3/2 × 40 = 60 mph
I hope this helps.
We have been given that Figure LMNO maps to L’M’N’O’ by a 125° rotation about point T. We are asked to choose correct congruency statement about our figures.
Since we know that rotations are isometric and they preserve angle measures.
We can see that after rotating figure LMNO about point T, angle L will correspond to angle L' and angle M, N and O will correspond to angles M', N' and O' respectively.
Therefore, figure LMNO will be congruent to L'M'N'O' and first option is the correct choice.
Answer:
y = 
Step-by-step explanation:
ax + yb = c ( subtract ax from both sides )
yb = c - ax ( isolate y by dividing both sides by b )
y =
