Divide 4 by both sides
Then you get 4=3+b2
Then subtracts 3 from four
You get 1=b2
False. consider u1 = (0, 0, 0), u2 = (1, 0, 0), u3 = (0, 1, 0), and u4 = (0, 0, 1).

You give us the answer right now. It's the answer to :
<span>If {u1, u2, u3} does not span R3, then neither does {u1, u2, u3, u4}.

Answer:
15 ft
Step-by-step explanation:
Let the height of the wall be represented bad x
Applying the theorem of similarity, we would have the following equation:
Cross multiply
2x = 30
Divide both sides by 2
x = 15
Thus, the height of the wall = 15 ft
Answer:r=20 cubic inches
Step-by-step explanation: Looking at this question critically and solving it mathematically, then we are going to say the volume of cylinder is πr^2h
V=15072 cubic inches r=? H=12cubic inches
15072cubic inches=3.14×r^2×12cubic inches
15072cubic inches=37.68 cubic incher^2
r^=400
We are going to take square of both sides, and our answer will now be
r=20 cubic inches
Answer:Fred has 13 9/10 minutes left for question C
Step-by-step explanation:
The total time that Fred has to do the three-problem quiz is 30 minutes.
He spent 10 7/10 minutes on question A. Converting 10 7/10 minutes to improper fraction, it becomes 107/10 minutes.
He spent 5 2/5 minutes on question B. Converting 5 2/5 minutes to improper fraction, it becomes 27/5 minutes.
Total time that Fred spent on question A and question B is
107/10 + 27/5 = (107 + 54)/10
= 161/10 minutes.
The amount of time that he has left for question C would be
30 - 161/10 = (300 - 161)/10 = 139/10
= 13 9/10 minutes
