1 answer:
Answer:
4
Step-by-step explanation:
The given fraction is
To clear the fraction, we need to multiply through by the LCM of the denominators.The denominators are 4, 2 and an invisible 1.
The LCM of {4,2,1} is 4.
We multiply through by 2 to obtain:
This simplifies to
The fraction is now eliminated. The required number is 4

Answer:
after 10 seconds the charge is 1.624
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one.
The electrical charge on a metal plate is given by the function below, where t is the time in seconds. What is the charge after 10 seconds?
C (t) = 12
My answer:
Given the information:
C (t) = 12
when t =10 we have:
C (10) = 12
<=> C (10) = 12
<=> C (10) = 12
<=> C (10) = 12 * 0.1353
<=> C (10) = 1.624
Hence, after 10 seconds the charge is 1.624
Answer:
Option A - $ 40.00 - $9.50 - $4.25 - $5.00
Step-by-step explanation:
Given : Tu went to the movies. he bought 2 tickets for $ 9.50 each, popcorn for $ 5.00, and 2 drinks for $ 4.25 each. He give the clerk two $ 20.00 bills.
To find : Which expression can not be used to find the amount of changes Tu got?
Solution :
He give the clerk two $ 20.00 bills i.e. or 40
He bought 2 tickets for $ 9.50 each i.e. or -9.50-9.50
Popcorn for $ 5.00 i.e.
2 drinks for $ 4.25 each i.e. or -4.35-4.25
The expression can not be used to find the amount of changes Tu got is
' $ 40.00 - $9.50 - $4.25 - $5.00'.
Therefore, option A is correct.
