Every triangle has a total of 180 degrees. If one angle measure is 100, then 180-100 is 80. This means that the other two angle measures have a total of 80. As angle j and k are equal, we divide 80 by 2, to get 40. This means that the measure of both angle j and k is 40 degrees. The measure of angle j is 40 degrees.
Answer:
A) x ≠ 0
B) x ≠ 3
Step-by-step explanation:
The domain is all the possible values of x such that f(x) exists.
A) f(x) = (x + 5) / x
x can't be 0 (can't divide by 0), so the domain of x is all values other than 0.
You can write this in interval notation:
(-∞, 0)⋃(0, ∞)
Inequality notation:
x < 0 or x > 0
Or simply:
x ≠ 0
B) f(x) = 1 / (x - 3)
x can't be 3 (can't divide by 0), so the domain of x is all values other than 3.
(-∞, 3)⋃(3, ∞)
x < 3 or x > 3
x ≠ 3
Hey there!
Markup is the percentage that the cost of an item is increased.
For example, if a company bought a pair of headphones that costed $100 and they sold it for $150, the markup was 50%, since half of the original cost was added. if the markup were 100% it would have been sold for $200, since it added 100% of the original.
I hope this helps!

Explanation:</h2>
Rounding to the nearest cent is the same as rounding to the nearest hundredth. In order to round this way, you must use the thousandths place so that you can know whether hundredths place rounds up or stays the same.
So the rules is as follows:
- If the thousandths place is 5 or above, we add 1 to the digit of the hundredths place.
For example:
0.64<u>8</u>3
4: It's in the hundredths place
<u>8</u>: It's in the thousandths place
8 is greater than 5, so we round it as:
0.65
- If the thousandths place 4 or below, the digit in the hundredths place stays the same.
18.9<u>2</u>3569
9: It's in the hundredths place
<u>2</u>: It's in the thousandths place
2 is less than 5, so we round it as:
18.92
