Answer:
0.135 images
Step-by-step explanation:
all you have to do is multiply 0.045× 3.
The answer is 0.135.
you have go move the decimals 3 times to the left
The answer is B) ii
The notation "p --> q" means "if p, then q". For example
p = it rains
q = the grass gets wet
So instead of writing out "if it rains, then the grass gets wet" we can write "p --> q" or "if p, then q". The former notation is preferred in a math class like this.
So when is the overall statement p --> q false? Well only if p is true leads to q being false. Why is that? It's because p must lead to q being true. The statement strongly implies this. If it rained and the grass didn't get wet, then the original "if...then" statement would be a lie, which is how I think of a logical false statement.
If it didn't rain (p = false), then the original "if...then" statement is irrelevant. It only applies if p were true. If p is false, then the conditional statement is known to be vacuously true. So this why cases iii and iv are true.
Answer:
36m
Step-by-step explanation:
If the area of a square is 81 m
A=81m
but we know that A=l² so l=radA
l=9m
p=4l
finally p=4•9=36m
Answer:
-0.2
Step-by-step explanation:
Answer:
12.6
Step-by-step explanation:
Given
with reference angle 57°
perpendicular (p) = y
hypotenuse (h) = 15
Now
sin 57° = p / h
0.84 = y / 15
y = 0.84 * 15
y = 12.6
Hope it will help :)
