Answer:
C. 7 weeks.
Step-by-step explanation:
Since the shrub was 64 cm tall at first, take away 64 from 76.6. Now we are left with 12.6. Let's divide 12.6 by 1.8 (that's how many cm it grows per week). When we do this, we are left with 7. This means it took 7 weeks for the shrub to reach 76.6 cm. I hope this helps!
Answer:
166.1
Step-by-step explanation:
It would become 11.5 * 7 + 10.7 * 8 = 80.5 + 85.6 = 166.1
the slopes of the sides do not matter. It's the fact that AD and BC are parallel and AB and DC are NOT parallel that determines it to be a trapezoid.
Answer: Width = 15cm
L = 31cm
Step-by-step explanation:
P = 92 cm
L = 1 + 2W
P = 2L + 2W
P = 2(1+2W) + 2W
P = 2+4W+2W
P = 2 + 6W
92cm = 2 + 6W
subtract 2 on both sides to cancel the 2 on the right side.
90cm = 6W
W = 90/6
Width = 15cm
L = 1+2W
L = 1 + 30cm
L = 31 cm
Verification:
P = 2L+2W
P = 2(31)+2(15)
P = 62+30
P = 92cm
Hope I Helped!
