You can divide 48 by 2 then divide the answer by 2, to get the answer.
First find her rate per hour by dividing $90 by 5 hours:
90 / 5 = 18
She makes $18 in one hour.
1 hour = 3600 seconds.
Divide her hourly rate by 3600 to find how much she makes per second:
18 / 3600 = $0.005 per second.
Now divide $0.25 by 0.005 to find the number of seconds needed:
0.25 / 0.005 = 50
It takes 50 seconds.
Answer:
The first one cannot be simplified
reason: usually when simplifying an expression you combine like terms but in the given expression there are no like terms
An example of like terms would be 6a and 9a
Essentially what i am saying is that the variables have to be the same in order for them to be combined
The second one is 36r
This is the answer because they tried to combine like terms that aren't similar
r and f are not the same variable therefore they cannot be combined
Hope this helps :)
Answer:
There are no solutions to this answer.
Step-by-step explanation:
I checked my answer by going to an app and they said there was no answer to the question too.
Recall that in a geometric sequence, you multiply the "current" one by the common ratio to get the "next" so, if you divide "next"/"current", the quotient is just the common ratio,
notice, all we did was, divide the value, by the number to its left-hand-side.
