Step-by-step explanation:
Hello!
Inez walked in the treadmill for 7/10hr and had stopped for 1/2hr. How much time he was actually working out?
Time in the treadmill is hr
1 hour is the whole, you can express it as .
If you express it in minutes then , then
Now you can calculate the amount of time he was on the treadmill:
Time he had stopped
Between the time he was on the treadmill and the time he rested, he worked out for 42 + 30= 72 min = 1 hour and 12 minutes.
During a 12- hour period, the temperature dropped 48 °C how many degrees did the temperature dropped each hour?
You can use cross multiplication to calculate how many degrees per hour the temperature decreased:
If in 12 hrs it decreased 48ºC
Then in 1 hr it decreased 4ºC
The elevation of Turpan Pendi in China is -185 meters. The elevation of the Qattara Depression in Egypt is -163 meters. Compare the two elevations using < or >.______________
To easily determine which elevation is higher than the other you have to order them from least to greatest in a number line. These measurements are negative, which means that, the "higher" the module is, the less in the number line the negative value will be:
----|---------------------------------------|--------------------------------|--
-185 -163 0
(The line is not on scale)
Using < or >, you can say that -163 meters > -185 meters.
I hope this helps!
