Answer:
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass <u>after</u><u> </u><u>4</u><u>2</u><u>0</u><u> </u><u>days</u><u> </u>
in order to solve so we can consider the half-life formula given by
where:
- f(t) is the remaining quantity of a substance after time t has elapsed.
- a is the initial quantity of this substance.
- T is the half-life
since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
reduce fraction:
By using calculator we acquire:
hence, the remaining sample after 420 days is 0.625 kg
Answer:
The cost of one bear is <u>$47,000</u>.
Step-by-step explanation:
The question is incomplete and the data is missing so the complete question with data is below with attached files:
To celebrate there 125 anniversary, a company in Germany produced 125 very expensive teddy bears. The bears,known as the "125 karat teddy bears", are made mohair,silk and gold thread and have diamond and sapphire eyes.
The chart shows the approximate cost of " 125 teddy bears". Based on the pattern, how much does one bear cost?
Now, to get the cost of one bear.
So, we solve it by using unitary method:
If 4 bears cost = $188,000.
Then 1 bear cost =
Thus, cost of one bear is $47,000.
Now, we check it by using another pattern of the data:
If 7 bears cost = $329,000.
Then 1 bear cost =
Hence, the cost of one bear is $47,000.
Therefore, the cost of one bear is $47,000.
