Answer:
True, True, False
Step-by-step explanation:
An easy way to solve fraction problems like this is to make each fraction have the same denominator. Since he has $100, the denominator will be 100.
2/10=?/100 10*10=100 1*10=20 20/100 of his money he wants to spend on video games
55/100 already has 100 as its denominator, so he wants to spend 55/100 on a skateboard.
3/10=?/100 10*10=100 3*10=100 30/100 is how much he wants to spend on comic books.
Add all of the fractions together to see how much he wants to spend and if he has enough.
20/100+55/100+30/100=105/100
He wants to spend $105, which is $5 more than he has.
I'm assuming that you are talking about sequences <3
In the context of a recursive formula where we have "n-1" in sub-index of "a", you can think of "a" as the previous term in the sequence. In the context of an explicit formula like "-5+2(n-1)" "n-1" represents how many times we need to add 2 to the first term to get the nth term.
Dw if you don't understand, sequences and functions isn't an easy topic
#30)
Pipe A filled for 3 days and pipe B filled for 2 days
Both can fill: 1/3 + 1/2 = 2/6 + 3/6 = 5/6
Answer: 5/6 of a day to fill the pool
If you're looking for the interest the answer would be:
i=8,000*.015*3
i=360.
The interest would be $360 dollars.
The balance would be 8,000+360= $8,360
