Someone plz help.The temperature started at 35°F. If the temperature went down 4°F and then up 2°F, whats is the temperature dif

timama [110]

Answer:

The temperature difference relative to the high temperature is -2°F.

Step-by-step explanation:

We are given that the temperature started at 35°F. The temperature went down 4°F and then up 2°F.

Firstly, the original temperature = 35°F

Now, it is stated that the temperature went down 4°F, this means that the temperature decreases by this amount.

So, the new temperature = 35°F - 4°F = 31°F

Now, the temperature went up by 2°F, this means that the temperature increases by this amount.

So, the final temperature = 31°F + 2°F = 33°F

Now, the final temperature difference relative to the high temperature is given by = 33°F - 35°F = -2°F.

{Here, the maximum temperature is 35°F}

If the speed of a car is 20 m s^-1 then what is its speed in km h^-1 ?<br>#no spam

ivanzaharov [21]

Speed in m/s=20m/s

We have to convert it to km/h

$\\ \sf\longmapsto 20\times \dfrac{3600}{1000}$

$\\ \sf\longmapsto 20\times \dfrac{18}{5}$

$\\ \sf\longmapsto 4times 18$

$\\ \sf\longmapsto 72km/h$
