Answers:
- JK = 29
- LM = 29
- KL = 10
- MJ = 10
- JK = LM and KL = MJ
========================================================
Explanation:
Let's plug in the given x value
- JK = 5x+9 = 5*4+9 = 20+9 = 29
- LM = 6x+5 = 6*4+5 = 24+5 = 29
Both JK and LM are equal to 29, so this means JK = ML
Now use the y value
- KL = 2y-6 = 2*8-6 = 16-6 = 10
- MJ = y+2 = 8+2 = 10
Both JM and KL are equal to 10, so JM = KL
These facts are sufficient to prove we have a parallelogram.
Answer:
f(-5) = 19
Step-by-step explanation:
f(t) = -3t+4
Let f(t) = 19
19 = -3t+4
Subtract 4 from each side
19 - 4 =-3t+4-4
15 = -3t
Divide each side by -3
15/-3 = -3t/-3
-5 = t
Step-by-step explanation:
Here, pole is making a right triangle with the wall and pole is acting as hypotenuse. Thus by using Pythagoras theorem the length of pole can be calculated as:
Hence, option B is the correct answer.
You know three team members do the butterfly. One more team member does the breaststroke. Therefore, 4 members do the breaststroke, because 3 + 1 = 4. Three times more do the sidestroke than the breaststroke, so you have to multiply 4 by 3 and get 12. 12 members do the sidestroke. If you add the 3 memebers doing the butterfly, the 4 memebers doing the breaststroke, and the 12 members doing the sidestroke, you get 19. Since the other half of the team is doing the crawl, you have to multiply 19 by two to get the whole team. 19 times two is 38. There are 38 members on the swim team.
Answer:
105.84 cm
Step-by-step explanation:
A = 1/2 bh
A = 1/2 (16.8) 12.6
A = 1/2 (211.68)
A = 105.84 cm
