37 I think I’m not sure just saying a random number don’t trust me I just needed the points
You have to add and divide for the mean(average) so add all of them up and then divide by 3 :)
Answer:
21:9, 14:6, 28:12
Step-by-step explanation:
literally just multiplying them by the same number:
7*3 : 3*3 = 21:9
etc.
Step-by-step explanation:
first you want to divide the ounces of liquid soap we have by the ounce bottles we have (58.5 / 4.5 = 13 )
so now we know we have 13 bottles of liquid soap
then you want to multiply the 13 bottles of soap by how much they sell each bottle for ( 13 x 5.50 = 71.50 )
the answer: the students would earn $71.50 if they sell all the bottles of liquid soap
hope that helps :)
The number of years it would take for radium to be 5 grams is 6967 years.
<h3>After how many years will only 5 grams of radium be present?</h3>
The formula that is used to represent continuous compounding or continuous decay is:
FV = A x
x N
Where:
- A= amount
- e = 2.7182818
- N = number of years
- r = interest rate
5 = 100 x e^−0.00043 x t.
In order to determine the value of t, take the following steps:
Divide both sides by 100
5/100 = e^−0.00043 x t.
Then take the In of both sides
= 6967 years
