<h3>
Answer: 350%</h3>
=========================================================
Explanation:
1 hour = 60 minutes
2 hours = 120 minutes (multiply both sides by 2)
2 hrs + 20 min = 120 min + 20 min (add 20 min to both sides)
2 hrs, 20 min = 140 min
Juan studied for 140 min
---------------------
Ken studied for 2/3 of an hour, so he studied for (2/3)*60 = 120/3 = 40 min
We see that Juan studied more than Ken, so that must mean Juan's study time as a percentage of Ken's study time is over 100%
This is because
- 100% of 40 min = 1.00*40 = 40 min
- 200% of 40 min = 2.00*40 = 80 min
- 300% of 40 min = 3.00*40 = 120 min
and so on
We divide Juan's time by Ken's time to get: 140/40 = 3.5 = 350%
350% of Ken's study time was Juan's study time.
In other words, if we take 350% of the 40 min figure, then we get 3.5*40 = 140 which represents Juan's study time.
If your teacher asked the reverse of this, and instead asked "what percent of Juan's study time was Ken's?", then the answer would be 40/140 = 0.2857 = 28.57% approximately.
Answer:
option D
Step-by-step explanation:
The area of a square depends upon the length of its sides
For side a, The area of the square is a²
Therefore a(s) = s²
Therefore, a square of 3 feet has an area of 9 square feet
Option D
whats your question?
Answer:
55+15x is the equation for amount of money it costs
Step-by-step explanation:
55 is deposit you have to pay no matter what and the x represents number of days you are renting, and per day you will have to pay 15 dollars so $15 x number of days + the 55 deposit is the equation but again, i dont know what the question is exactly
Length=x
width = x+7
Area =length* width =x(x+7)=170
x^2+7x=170
x^2+7x-170=0
Answer:
162.5
