Part 1.

A is.

45 and 34 wood pieces left

B is.

It takes 11 cause 100-89=11 and 11+89=100 and it keeps subtracting 11.

C is.

I dont understand the question(sorry)

D is.

At least 9 shelves,

100-11=89

89-11=78

78-11=67

67-11=56

56-11=45

45-11=34

34-11=23

23-11=12

12-11=1

And you would have 1 wood piece remaining!!

Question 1.
Part one
A. After you build 5 you get 45 pieces, then after you build 6 you get 34.

B. It takes 11 pieces of wood to build each shelf

C. It is negative since y is decreasing in value, while x increases

D. you can build nine shelves
Not sure if there is a specific method you need to use, but you can just do 100 divided by 11 to get 9 remainder something, but you can only build full shelves.

Part 2
A. It took 20 minutes to set up building materials, since the line starts at the y-intercept at (0,20)

B. It takes 25 minutes to build each shelf, since the graph shows that after the first shelf there was a twenty five minute increase from 20 to 45

C. If you work at a constant rate it will take 225 minutes to build nine shelves, you can do this by either multiplying 9 by 25 or continuing the line on the graph.

D. You spent 320 minutes preparing and building 12 shelves. Since we already know it takes 20 minutes to prepare, you just need to multiply 12 by 25 to get 300, then you add them together to get 320.

E. This line represents the amount of time it takes to build shelves


Question 2

A.the initial deposit was $95

B. The line would represent the decrease of money in your account, caused by the maintenance fee.

C. The line will be negative since the y outputs decrease by 6.5

D. The monthly maintenance fee is $6.5, you know this by looking at the difference in outputs

E. After sixth months in total, the remaining balance is $56, you multiply 6.5 by 6 months to get 39, then subtract that from 95.

F. Your balance will be negative after 15 months, just divide 95 by 6.5 then round the answer up

A 3,7, and 11

Step-by-step explanation:

Domain is the x-value so you replace all the x's in f(x)=-x+5 with -3,3, and 9

f(-3)=2/3(-3)+5

= 3

f(3)=2/3(3)+5

=7

f(9)=2/3(9)+5

=11

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.

Answers

Answer:

29.88 inches

Step-by-step explanation:

Equation of a line is given in the form  

Where

m is the slope [rate of change, here, rate of decrease]

c is the y-intercept [at 1920, the snowfall]

From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24

Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:

y = mx + b

y = -0.24 x +48.6

To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:

y = -0.24(78) + 48.6 = 29.88 inches
