4 dimes=4 *10=40 cents
2.25-0.40=1.85
1.85=0.05 times number of nickles
times 100 both sides
185=5 times number of nickels
divide both sides by 5
37=number of nickles
has 37 nickles
To find this answer you simply subtract eight from sixty-two, which gives you....
54!
So there are 54 student in the science club!
Hope this helps! :)
Answer:
First Problem:
1/2 * -2 2/5 = 1/2 * -12/5 = -12/10
Simplify -12/10 into -6/5
Step-by-step explanation:
Answer: There are 2.25×10³⁴ bacteria at the end of 24 hours.
Step-by-step explanation:
Since we have given that
Number of bacteria initially = 1
It triples in number every 20 minutes.
So, 
So, our equation becomes

We need to find the number of bacteria that it will contain at the end of 24 hours.
So, it becomes,

Hence, there are 2.25×10³⁴ bacteria at the end of 24 hours.
To answer the question above, isolate F on the other side of the equation by multiplying both sides by 9/5. This gives,
(9/5) C = F - 32
Next, transpose -32 to left side.
(9/5)C + 32 = F
Rearrange the equation to give an answer of
F = (9/5)C + 32
