Complement means the other angle that will sum up to 90°
So:
x + 2x = 90°
3x = 90
x = 30°
So, it is 30° and 30 * 2°, or 60°
Answer:
Selling price= $580
Step-by-step explanation:
eGiving the following information:
Buying price= $400
Mark-up percentage= 45% = 0.45
<u>The manager applies a mark-up equivalent to 45% of the buying price. First, we need to determine how much is 45% of the cost.</u>
Mark-up= buying price* Mark-up percentage
Mark-up= 400*0.45
Mark-up= $180
<u>Now, the selling price:</u>
Selling price= 400 + 180
Selling price= $580
Hello!
Really, we could finish this problem without knowing the slope or just having one of the given points.
However, since they gave us the slope, let's take the easier way.
y = 2x + b
To find b, we can plug in one of the points. (it doesn't matter which)
7 = 2(5) + b
7 = 10 + b
b = 7-10 = -3
So, the final equation is y = 2x - 3 or answer choice D.
Hope this helps!! let me know if you have ANY questions.
