The radius is found from
... A = πr²
... r = √(A/π) = √(154/π) m ≈ 7.00 m
The circumference is then
... C = 2πr = 2π(7.00 m) ≈ 43.99 m
The circumference is about 44.0 m.
The pattern is: Ducks always swim on that pond <em><u>in powers of 2</u></em> .
Monday ........ 2⁰ = 1
Tuesday ........ 2¹ = 2
Wednesday ... 2² = 4
Thursday ....... 2³ = 8
So
Friday ........... 2⁴ = 16
<em>Saturday ...... 2⁵ = 32</em> <=== the answer
AND ...
If they kept doing this for a month, then
on the 31st day there would be
2³⁰ = <em>1,073,741,824</em> (more than 1 billion) ducks out there !
Answer:
the first one
Step-by-step explanation:
Yes.
For example, the LCM of 12 and 36 is 36, because factoring these numbers gives
12 = 2^2 * 3
36 = 2^2 * 3^2
So, to match them, just multiply the twelve by 3, then they're both 36.
Answer:
7*10+8X>=206
Step-by-step explanation:
multiply time 10 then you add the answer to that with 8X and then that answer is the answer to your problem
