Answer:
c
Step-by-step explanation:
C. BD= 20
Use similar triangles to write a proportion and then cross multiply to solve.
AE: AC = AD:AB
(ONCE YOU KNOW AB YOU CAN SUBTRACT AD FROM AB TO GET BD =20)
So, 15:40 = 12: AB=32. now 32-12 = 20 so BD = 20
Answer: p < 24
Step-by-step explanation: I'm assuming you mean solving for P
1. We want to get p alone and the first step would be to subtract 4 from both side which will give us: ⅔p < 16
2. Next step would to be multiplying by 3 from both sides and doing this will cancel out the 3 in the denominator giving you: 2p < 48
3. Now we have to divide both sides by 2 and we are done which gives us:
<u>p < 24</u>
<u></u>
Don't forget if we were to be dividing by a negative the sign would flip
(for example: -2p < 6 = p > 3) this isn't used in this problem but just a reminder if you see this in future problems
You need to find the WPM (words per minute) of each person.
Andre - 208 divided by 4 = 52
Noah - 342 divided by 6 = 57
You now know that Andre types 52 words per minute and Noah types 57 words per minute.
Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.
