a mercury thermometer records a temperature of 8 degrees fahrenheit at 10 a. m. if the temperature drops by 3 degrees fahrenheit every hour what will be the temperature by 2 p. m. of the same day

-4 Degrees Fahrenheit

Step-by-step explanation:

Given

---- at 10am

Required

Determine the final temperature at 2pm

First, we need to determine the hour from 10am to 2pm (Both inclusive)

To solve further, we make use of the following Arithmetic Progression formula:

Where

--- Initial

--- difference

-- 5th term

--- Final temperature at 2pm

So: we have:

Hence:

The temperature is -4 Degrees Fahrenheit

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

560

hope this : )
