Answer:
60/100
Step-by-step explanation:
We know that 20 goes into 100 5 times, so we multiple numerator and denominator by 20 to get an equivalent fraction:

Heck naw Fawk that -3-!!!!!
Each cat would get 1/20 of the whole bag of cat food.
Answer:
T = 47.1875°C
Step-by-step explanation:
Given:
Surrounding temp, Ts = 100°C
Initial Temperature ,T0= 20°C
Increase in temperature = 15°C
Final temperature, T = 20 + 15 = 35°C
Time, t = 9 seconds
Let's take Newton's law of cooling:

We'll solve for k

Divide both sides by -5


Let's now find the temperature of the ball after 18 seconds in boiling water.
Use the Newton's equation again:




T = 47.1875°C
Temperature of the ball after 18 seconds in boiling water is 47.1875°C
The answer to this equation is -24 because in each of the parentheses the product is -12 and negative numbers add to each other
