Answer:
Answer choice B
Step-by-step explanation:
Law of sines
Answer:
220
Step-by-step explanation:
Let us assume that x number of necklaces are to be fixed to break even i.e. cost price = profit.
Now, cost for x necklaces is 35x + 1650, and selling price is 85x. {As per given condition}
Therefore, profit will be = 85x - (35x +1650) =50x -1650
Hence, to make break even, the condition is
50x - 1650 = 35x + 1650
⇒15 x =3300
⇒ x =220.
Hence, 220 number of necklaces must the jeweler fix to break even. (Answer)
<span>2x-3y=6
3y = 2x - 6
y = 2/3 x - 2 so slope = 2/3
</span><span>parallel lines slope is the same and equal 2/3
</span><span>passes through the point (9,-3)
y = mx + b
b= y - mx
b= -3 - (2/3)(9)
b= -3 -6
b= -9
equation
y = 2/3 x - 9
or
3y = 2x - 27
2x - 3y = 27 ...standard form</span>
Since triangle BDE is right, we can check it for special rules: BD is hypotenuse = 20, and BE = 12, both divisible by 4: get 5 and 3... so it's a 3-4-5 special right triangle, the 4×4 = 16 m for side DE.
Since AD bisects angle A, I think then side DG should be congruent with DG. So then
DG = 16 m
