Theo is a cleaner.

marusya05 [52]

Answer:

2:15 pm

Step-by-step explanation:

The time that Theo finishes is the sum of the start time and the duration of the cleaning. The duration is the sum of the cleaning times for each of the rooms and the break time.

<h3>sum of minutes</h3>

It is convenient to convert all of the times to minutes, then convert the total back to hours and minutes.

kitchen +lounge +bedroom +bathroom +breaks

= (60 +50) +(55) +(1/2×60) +(35) +(85)

= 110 +55 +30 +35 +85

= 315 . . . . minutes

<h3>minutes and hours</h3>

There are 60 minutes in an hour, so the sum is ...

(315/60) hours = 5 15/60 hours = 5:15 . . . . written as hours : minutes

Then the time Theo finishes is ...

9:00 +5:15 = 14:15 = 2:15 pm

Theo will finish cleaning at 2:15 pm.

For one month Siera calculated her home town’s average high temperature in degrees Fahrenheit. She wants to convert that tempera

SVETLANKA909090 [29]

We have to find how can someone convert the temperature from degrees Farhenheit to degrees Celsius using the function. The temperature in degrees Celsius is equal to the temperature in degrees Farhenheit minus 32 times 5/9. Or C ( F ) = ( F - 32 ) * 5/9. For example: the temperature is F = 50°; C ( 50 ) = ( 50 - 32 ) * 5/9 = 18 * 5/ 9 = 10 °C. Answer: The function is: C ( F ) = ( F - 32 ) * 5/9.
