Answer:

16 degrees Celsius, with breaks at 172 degrees Fahrenheit.

Step-by-step explanation:

To calculate 86 degrees in Fahrenheit you need to take the 86 degrees you are given and first mulitply it by 5 over 9 (5/9). That will give you about 48 degrees. To finish solving it for celsius you then need to take your 48 and subtract 32, in which you would get 16. So, the temprature Tom needs to take a break at is 172 degrees Fahrenheit.

Step-by-step explanation:

The key to solving this question is to find the distance bwtween the two points given

distance=y2-y1/x2-x1

(2,4)(4,8)

2=x1,4=y1

4=x2

8=y2

8-4/4-2

4/2=2

Inessa05 [86]

Answer:

200 and 5

Step-by-step explanation:

1. 9.9 rounded is 10

1.79 rounded is 2

10^2 is 100

100 x 2 = 200

2. 97.5 rounded is 100

1.96 rounded is 2

square root of 100 is 10

10/2 = 5

erma4kov [3.2K]

Answer:

a) Cost

$C(q) = 50+16q\\\\C(500)=50+16(500)=50+8,000=8,050$

b) Sales income

$S(q)=20q\\\\S(500)=20\cdot 500 = 10,000$

c) Table of values

$\left[\begin{array}{ccc}q&C(q)&S(q)\\0&50&0\\250&4,050&5,000\\500&8,050&10,000\end{array}\right]$

d) Attached

e) Breakeven point = 12.5 sheets

f) Profit at 550 sheets = $1,950

Step-by-step explanation:

a) We have a fixed cost for the image, at $50.

We also have a variable cost of $16 a sheet.

The purchased quantity is 500 sheets.

Then, the cost function is:

$C(q) = 50+16q\\\\C(500)=50+16(500)=50+8,000=8,050$

b) The price for each sheet is $20, so the income from sales are:

$S(q)=20q\\\\S(500)=20\cdot 500 = 10,000$

c) Table of values

$\left[\begin{array}{ccc}q&C(q)&S(q)\\0&50&0\\250&4,050&5,000\\500&8,050&10,000\end{array}\right]$

d) Attached

e) The minimum number of sheets the group must sell so they don't lose any money is the breakeven point (BEP) and can be calculated making the income sales equal to the cost:

$S(q)=C(q)\\\\20q=50+16q\\\\(20-16)q=50\\\\4q=50\\\\q=50/4=12.5$
