Ice is placed around a bowl of water to lower the temperature. the equation d=−7/5t+22 shows the time, t, measured in minutes and temperature, d, measured in degrees celsius. which statement is correct? a)the temperature of the water decreases 5°c every 7 minutes. b)the temperature of the water increases 7°c every 5 minutes. c)the temperature of the ice that is around the bowl is 22°c d)before cooling begins, the temperature of the water is 22°c

d)Before cooling begins, the temperature of the water is 22°C

Step-by-step explanation:

Given equation that shows the temperature of the bowl after t minutes,

Initially ( when ice is not placed ) t = 0,

So, the temperature of the water,

i.e. Option d) is correct.

If t = 7 minutes,

The temperature would be,

So, the change in temperature = 12.2° - 22° = -9.8°,

Thus, option a) is incorrect.

If x = 5 minutes,

The temperature would be,

Change in temperature = 15° - 22° = -7°,

So, Option b) is incorrect.

∵ The temperature of the ice must be less than 22°,

Thus, option c) is incorrect.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
