Kareem heats a beaker of water to boil. Then he records that the water temperature decreases from 100% C to 19 C in 5 2/5 minutes. What was the charged in temperature each minute?

Given :

Kareem heats a beaker of water to boil. Then he records that the water temperature decreases from 100° C to 19° C in 5 2/5 minutes.

To Find :

What was the charged in temperature each minute.

Solution :

Time taken to reach 19° C :

Now, change in temperature per minute is given by :

Therefore, the charged in temperature each minute is -15 °C/minute .

Hence, this is the required solution.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
