<span><span>1.       </span>Hector earns $24 dollars for every 3 hours. Of work
=> Myrna earns $17 dollars for every 2 hours of work.
Let’s solve for both rates per hour.
=> HECTOR
=> 24 dollars for 3 hours
Simpl divide 24 by 3 to get the hourly rate
=> 24 / 3 = 8
=> 8 dollars / hr
=> MYRNA
=> 17 dollars for 2 hour
Divide 17 / 2 to get the rate of Myrna per hour
=> 17 / 2
=> 8.5 dollars / hour.
Thus, Myrna earns higher than Hector.</span>

xxTIMURxx [149]

After 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.

<h3>What is exponential decay?</h3>

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

We know the decay can be as:

\rm C = a(1-r)^t

We have:

a = 470 grams

r = 3% = 0.03

t = 6 hours

\rm C = 470(1-0.03)^6

C = 391.49 grams

Thus, after 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.

jada uses a pitcher to fill a pot of water. the pitcher holds 8/10 liter of water. it takes 12 full pitchers of water to fill th
Bingel [31]

Answer:

The pot can hold 9 6/10 liters of water

Step-by-step explanation:

Since you know that the pitcher can hold 8/10 liters of water and that Jada has to fill the pitcher 12 times to fill the pot you would first convert the 8/10 liters that the pitcher can hold to a decimal so that would become 0.8 liters of water and then you would multiply the 0.8 by 12 to get 9.6 liters of water and then you can convert that back to a fraction which would be 9 6/10 liters of water. So the pot can hold 9 6/10 liters of water
