A 10-pound block of ice melts at a rate of 3% per hour. Find the weight of the block of ice after 1 day.

The weight of the block of ice after 1 day is of 4.81 pounds.

Step-by-step explanation:

Equation for exponential decay:

The equation that models an amount after t hours, subject to exponential decay, is given by:

In which A(0) is the initial amount and r is the decay rate, as a decimal.

A 10-pound block of ice melts at a rate of 3% per hour.

This means that

So

Find the weight of the block of ice after 1 day.

One day has 24 hours, so this is A(24).

The weight of the block of ice after 1 day is of 4.81 pounds.

answer: howdy

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
