Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150
The answer is <span>A.0.5 moles
</span><span>a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
</span><span>you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g
1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M</span>
Answer:
There was an association between taking breaks and better performance, but it's not necessarily a causal relationship.
Step-by-step explanation:
Answer:
contrapositive
Step-by-step explanation:
The <u>converse</u> statement would be ...
b ⇒ a
The <u>contrapositive</u> swaps the parts and negates them both:
¬b ⇒ ¬a . . . . . matches your given statement
The <u>inverse</u> negates both parts:
¬a ⇒ ¬b
A <u>contradiction</u> arises when the implication is false: a is true and b is false.
268214 / 3 = 89404.66667 (89405 rounded up)
89405 * 2 = 178810
268214 - <span>178810 = 89404
</span>
the 2 integers are 89405 and 89404
