Answer:
115
Step-by-step explanation:
20% is one fifth. If Mary has one fifth fewer than Susan, then she has 4 fifths of what Susan has. So 92 is 4 fifths of some number.
To find out what one fifth is, you can divide 92 by 4 because it is four fifths.
92/4 = 23
So one fifth of the number of blouses Susan has is 23. Now you can multiply 23 by 5 to get the total number of blouses Susan has.
23 * 5 = 115
A(4) =13
a(1) = 1
a(2)=5
a(3)=9
a(4)=13
a(5)=17
So, the arithmetic formula is: a(n) = a(n-1) + d
If we look at the formula, the numbers change by +1, which is our d
We can test our formula by look for 2,
a(2)= a(2-1)+4
a(1)+4
1+4
a(2)=5
Even though the sequence tells us, we can test our formula anyhow
a(4)= a(4-1)+4
a(3)+4
9+4
a(4)=13
Answer: 33.33 minutes longer.
Step-by-step explanation :
We need to remember the following formula:
Where "t" is the time, "d" is the distance and "V" is the speed.
We know that she runs approximately 5.4 miles per hour, then:
Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:
Making the conversion from hours to minutes, we get:
Since she plans to run 12 miles on Thursday, her run's time on that day will be:
Making the conversion from hours to minutes, we get:
Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:
