Answer:
420
Step-by-step explanation:
20 percent of 350 is 70, so adding that on will give us the price it is sold at for profit of 70 (20%).
AOD=180 so COD=48
Since point C and D are equidistance to center point(O) OD and OC are congruent.
That also means OCD=ODC.
180-48=OCD+ODC
ODC=OCD
x= 66
Answer:
Approximately 7.8 units
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:

From the graph, we can see that A is (0,0). Let's let this be x₁ and y₁.
B is (-5,6). Let's let this be x₂ and y₂. So, substitute:

Simplify:

Square:

Add:

Take the square root. Use a calculator:

So, the distance between them is about 7.8 units.
And we're done!
