Answer:
a. x is the width of the fence in feet and y is the length of the fence in feet , f = 2x+ 2y equation represents that the fence is twice the width and twice the length , x>10 represents that the width should be atleast 10 feet , y >8 represents that the length should be at least 8 feet , 3f<120 represents the cost constraint. it says that the fencing cost $3 per foot and should cost less than or equal to 120 . b. yes, i agree. this is because the inequality f>0 implies that the length of the fencing should be greater than 0. I hope this helps ! :)
It would be y=Mx+b that is the answer
Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
Answer:
38.46%
Step-by-step explanation:
There are 91 students and 35 of them received a score of 90 or above.
So, there are 35/91 students with an A grade.
The probability to pick a random student that would be the same proportion that those who got the right score, so 35 / 91 = 0.3846 or 38.46%
38.46% of chances to pick someone who got an A (90 score or above), and, the opposite, 61.54% of chances to pick someone who didn't get an A. That's a strong class!
