Answer:
6973568802
Step-by-step explanation:
I memorized the equation: A(n) = A(1)*d^(n-1).
You can plug into the equation A(21) = 2*3^20, which can be solved to 6973568802. (I solved this step through a calculator by finding 3^20, then multiplying that by 2 to get 6973568802.
Hope this helps!
I think it’s C because if you do 24 plus 190 you get 214
Answer:
96 in²
Step-by-step explanation:
the bottom area is 6x6 = 36 in²
each of the 4 sides are 6x5x0.5 = 15 in²
4(15) + 36 = 96 in²
#21: (4•4) + (7•7)= (c•c)
16+49= (c•c)
65=(c•c)
_/65= c
#22: 22+90= 112
180-112= 68
68
#23: (3.5•3.5) + (4.7•4.7) = (c•c)
12.25 + 22.09= (c•c)
34.34= (c•c)
_/34.34= c
#24: 22+90= 112
180-112= 68
68
Answer: A) 2.5 km/ hour
You divide 10/4 and get 2.5, so 2.5km an hour.
B) 6.25 km/ hour
You have 2.5km/ hour plus 10km/ hour OVER 2. This would equal 12.5 km over 2
You then get 6.25 from doing 12.5/2
