I'm pretty sure it's 2 because 8x1/4 = 2, I hope this helped

Which of the following describes how to graph the line whose equation is y = x - 1?

jenyasd209 [6]

You would need to substitute a number for y. I would probably put 0 for y which would then give you x.

y = 0

x = 1

Then you can easily graph the point. :)

What are the measures of Angles d, e, and f? Show your work and explain your answers. (10 points)

Sholpan [36]

Answer:

Part A - Angle d is 29º

Part B - Angle e is 61º

Part C - Angle f is 95º

Part D - the box represents a 90º angle

Step-by-step explanation:

Angle d is 29º because of the vertical angles theorem

Angle e is 61º because if you take into account that it tells you one of the angles is 90º, you'll add d, which is 29º, to that in order to get 119. Then you'll subtract 119 from 180, as all the angles in a triangle must have a sum of 180º degrees. The result should be 61º

Although it looks rather acute, f should be 95 degrees because it's a supplementary angle with 85º, meaning you subtract 85 from 180

The box in the triangle is just a symbol indicating a 90º angle

Jack's Lumber Yard receives 8,000 large trees each period that it subsequently processes into rough logs by stripping off the tr

nasty-shy [4]

Answer:

1. $3,960,000

2. $3,840,000

3. Sell the logs.

Step-by-step explanation:

The questions are incomplete:

1. What is the contribution to income from selling the logs for log cabin construction?

2. What is the contribution to income from processing the logs into lumber?

3. Should Jack’s continue to sell the logs or process them further into lumber?

1. The contribution income is the total income generated by the sales of the rough logs. Each one contributes with $495.

Contribution to income (log cabin construction) = $495*8,000 = $3,960,000

2. In this case, we have to calculate what is the profit after processing each board, then multypling by the amount of boards per log and lastly multiplying by the total amoun of logs.

Contribution to income (processed board) = $(0.75-0.15)*800*8000

Contribution to income (processed board) = $0.6*800*8000

Contribution to income (processed board) = $480*8000 = $3,840,000

3. Jack should continue to sell logs for cabin construction because the profit per log is higher than for the processed board ($495/log versus $480/log).

Of 212 consumers polled, some like only animated movies, some prefer just musicals, and some like both. If 74 people like only a

iogann1982 [59]

52 people like only musicals.

There are 212 people. We know that the only answers were only animated movies, only musicals, or both. We also know that 74 people like only animated movies, and 86 people like both. To find the number that like only musicals, subtract these from the total number of people:

212-(74+86) = 212-160 = 52
