Answer:
Rotational symmetry of 180 degrees around the origin - yes
Rotational symmetry of 270 degrees around the origin - no
Step-by-step explanation:
thanks to math bits notebook we can see a visual representation
As you can see the parallelogram has rotational symmetry of 180
Answer : D
How to: use the properties of radicals 5 squared x 6 then simplify the root
Answer:
A=464
B=93
Step-by-step explanation:
A+B=557
A-B=371
Solving the two equations simultaneously gives A=464 and B=93
We can solve this problem by using the formula:
s = σ / sqrt(n)
where,
s = standard deviation of the sample
σ = standard deviation of the population = 3 years
n = number of samples = 100
Substituting:
s = 3 years / sqrt (100)
s = 0.3 years (ANSWER)
Answer:
I believe it might be 30 or 1.2
Step-by-step explanation:
It would've been 6/30 but since is it says it's a whole number you would have to add all the numbers together to get how many marbles you have in all.
I hope this is right, if it's not I'm sorry!
