A≈2.78
30 x 5 = 150
150/54 ≈ 2.78
Answer: C.
Step-by-step explanation:
To find the discounted value off of a full price, you can multiply the full price by the discount percentage to find the discount:
250 * 0.20 = 50
The discount is 50 dollars.
The laptop costs $250, but with the discount of $50, it is now for sale for $200.
The correct answer is C.
So the question wants you to add all the coins together then subtract 15% SO
16+28+32+4=80
so 15% of 10=10%+5%
5%=1/2 of 10% so
10% of 80=8
5% of 80=10%/2=8/2=4
8+4=12
he sold 12 coins
Answer:

Step-by-step explanation:
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle.
To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
If you want to know how to find the perpendicular bisector of two points, just follow these steps
midpoint = <u>(X₁ + X₂ </u> , <u> Y₁ + Y₂ )</u>
2 2
The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm
