A scuba diver wants to descend at an average rate of at least 7 feet per minute for 5 minutes. The table shows how many feet the
gladu [14]

The scuba diver must descend 3 feet in the fifth minute to meet the goal.

Why?

To find how many feet does the scuba diver need to descend to reach the goal of 35 feet in 5 minutes, we need to calculate how many feet he did descend on the first 4 minutes.

So, calculating we have:

FirstMinute=9ft\\SecondMinute=11ft\\ThirdMinute=5ft\\FourthMinute=7ft\\Total=9ft+11ft+5ft+7ft=32ft\\\\Goal=35ft\\\\Needed=Goal-Total(4Minutes)\\\\Needed=35ft-32ft=3ft

Hence, we can see that at the 4 minute, he has only descended 32ft. It means that he need to descend 3 feet more in the fifth minute.

Have a nice day!

k-4/3= 3

Mutiply both sides by 3 .

(3)(k-4/3)= (3)(3)

Cross out 3 and 3 , divide by 3 and then becomes k-4= 9

Move -4 to the other side

Sign changes from -4 to +4

k-4+4= 9+4

Answer:

Answer+Step-by-step explanation: 2019 game of the year award limited edition.

Step-by-step explanation:

This is all about carefully examining the slope. If you look carefully you will notice B curves in at the top just a little more than A so the first one is correct.

The second one is obviously not true.

The third one is disproved by the first.

The fourth one is correct as C is the peak and has little to no drop or rise.

The 5th one is correct, after spending several minutes examining it with 200%+ zoom I will tell you that it is correct B and D are the same.

I'm not 100% sure but I'm probably 95% sure that The 6th one is incorrect and A is changing height faster than D.
