Dequan is making homemade ice cream which needs to be frozen gradually to achieve the best texture. When he starts, the temperature of the ice cream is 50°F. The temperature drops 5°F each hour for the next 3 hours. Dequan then puts it in a deep freezer causing the temperature to drop 13°F. Which integer best represents the change in the temperature of the ice cream from start to finish? -28°F -28°F -13°F -13°F 13°F 13°F 28°F

The change in the temperature of the ice cream from start to finish is -28°F

Step-by-step explanation:

From the question,

Initial temperature of the ice cream is 50°F.

Also, the temperature drops 5°F each hour for the next 3 hours; that is for every hour in the next 3 hours, the initial temperature decreases by 5°F.

Then after 3 hours, the initial temperature would have decreased by 3 × 5°F;

3 × 5°F = 15°F

Hence, after 3 hours, the temperature of the ice cream would be 50°F -15°F;

50°F - 15°F = 35°F

After 3 hours, the temperature of the ice cream would be 35°F.

From the question,

Dequan then puts it in a deep freezer causing the temperature to drop 13°F

Now, the final temperature of the ice cream is 35°F - 13°F = 22°F

The final temperature of the ice cream is 22°F.

To determine the change in the temperature of the ice cream from start to finish,

Change in temperature = Final temperature - Initial temperature

Change in temperature = 22°F - 50°F = -28°F

Hence, the change in the temperature of the ice cream from start to finish is -28°F.

answer: get jesus in your life

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
