Answer:
-1,-3,-9,-27,-81,-243...
Step-by-step explanation:
Area of base = 1/2 x 4 x 3.5 = 7 m²
Perimeter of the base = 4 + 4 + 4 = 12 m
Surface area = 7 + 7 + 12 x 11 = 146 m²
Answer: 146 m²
So first find time elapsed
10:40-11:40=1
11:40-12:40=1
12:40-1:10=0.5 or 30 mins
so add
1+1+0.5=2.5, 2 hours 30 mins
3 miles per hour
3 times numberof ohours
3 times 2.5
7.5
answer is 7.5 miles
I’m pretty sure it’s 39.
explanation: 18x2= 36 and 3 is 39.
