The amount of time it take for an ice cube to melt varies inversely to the air temperature, in degrees. at 70 , the ice will melt in 20 min. how long will it take the ice to melt if it the tempature is 85f?

It will take 47.554 minute to melt the ice cube at 90°F

Step-by-step explanation:

We have given temperature in Fahrenheit is 85°F

From degree Celsius to Fahrenheit we know that

So

According to question time taken to melt ice is inversely proportional to temperature

So , here T is temperature and t is time

So

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
