The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours. daryl plans to be gone for at least 6 hours, and he has a plant outside. if he wants the plant to remain in temperature above -10°c, should daryl move his plant to a warmer location before leaving?

The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

Temperature drops by 5°c per hour

So we find the temperature after 6 hours

In 1 hour temperature drops= 5°c

So in 6 hours = 6* 5 = 30°c

In 6 hours , temperature drops by 30°c

the actual temperature is 20°c. after 6 hours the temperature becomes

20°c - 30°c= -10°c

So, after 6 hours the temperature will be -10°c

Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

In 6 hours or more than 6 hours , the temperature will drop less than  -10°c.

So, Daryl should move his plant to a warmer location before leaving

An inequality to model the problem is  

✔ 20 - 5x > -10

.

The solution is  

✔ x < 6

Step-by-step explanation:

no one could find the answer so here it is.u r welcome

8y^50

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
