Choose all answers that are correct. A. Draw a diagram. Eight people at 1 table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table. Count the number of round tables. B. Use logical reasoning. Start with 28 people, subtract 8 people who will sit at the dining room table, that leaves 20 people. Keep subtracting 4 people until you get to 0.

Helen determined she walks about 1,800 steps per 4/5 mile. How many steps did she take if she walked 3 miles?

Answers

$1,800\ steps\ \ \rightarrow\ \ (4)/(5) \ mile\n x\ \ \rightarrow\ \ 3\ miles\n \n(4)/(5) \cdot x=1,800\cdot 3\ /\cdot(5)/(4) \n \nx=1,800\cdot(5)/(4)\cdot3 \n \nx=450\cdot15\n \nx=6750\ [steps]$

I think the answer is 6750 steps

Risa is preparing a short oral presentation about singer, songwriter, and American icon Bob Dylan and the cultural impact of his music. Which multimedia sources should she include in her presentation? Check all that apply.A) a podcast in which Dylan’s life and work are discussed

B) an audio clip of one of Dylan’s most influential songs

C) a recording of Dylan’s most influential album

D) a photograph of Dylan performing at a concert

E) an article about Dylan’s influence on his fans

Answers

Pretty sure this isn't math.

I'd skip A -- it's Risa's presentation, not some podcasters'

B. An audio clip. Of course this should be included. I'd go with "Like a Rolling Stone."

C. An entire album is 45 minutes or so, too long for a short oral presentation. Skip the recording but some full size album covers containing actual vinyl records would be a nice touch.

D. Sure, photographs would work nicely.

E. Risa can cite any articles she used to prepare, but a full article has a lot of words and doesn't make sense as part as a short presentation. Maybe some slides with quotes from some articles would be more appropriate.

Answer: B, D
