Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)
Well, when you simplify 3/12 it equals 1/4 so if you multiply that by 3 and multiply 2/3 by 4 to get common denominators, you have 3/12 and 8/12, so yes, 3/12 is less than 2/3. I hope this helps cx
Answer: 50
Step-by-step explanation:
From the question, we are informed that 1/3 of gym members say they spent 5 hours per week at the gym.
Assuming there are 150 people working out at the gym, the number of people that'll most likely spend 5 hours at the gym this week will be calculated by multiplying 1/3 by 150. This will be:
= 1/3 × 150
= 50 people
(-6,-9) is what I got hope this helps
10 I think because 10+10+8+8=36 and 8 is 2 less than 10
