Answer:

  1. (d) 151 in

  2. (a) 43.3 in

Step-by-step explanation:

1. The circumference is ...

  C = 2πr

  C = 2(3.14)(24 in) = 150.72 in

  C ≈ 151 in

__

2. C = 2πr

  r = C/(2π) = 272.2 in/(2·3.14) ≈ 43.3439 in

  r ≈ 43.3 in

A container contains water at temperature 80 degree celcius. After every 10 minutes, the change in temperature is - 4 degree cel
lilavasa [31]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of minutes
 y: final temperature
 We write then the equation that models the problem:
 y = (-4/10) x + 80&#10;
 For y = 20 we have:
 20 = (-4/10) x + 80&#10;
 Clearing x:
 (4/10) x = 80 - 20&#10;&#10;x = (10/4) * 60&#10;&#10;x = 150
 Answer:
 
The temperature of the water will be 20 degree celcius after 150 minutes

At 2:00 PM the temperature is 18°F. At 10:00 PM the temperature is -9°F.
Diano4ka-milaya [45]

Answer:

To figure out the change, we subtract the original temperature by the following after temperature.

18°F - original

-9°F - subsequent time after original

So we set up the equation;

18°F - (-9°F)

(Two negatives combine to form a positive)

18°F + 9°F

= <u>27°F</u> was the change in temperature.
