Answer:
Place the compass point on vertex Y and draw an arc that intersects YX and YZ
Step-by-step explanation:
Given the construction of dividing an angle inteo two equal parts.
we have to find the first step of construction.
As seen in figure the angle ∠XYZ is dividing into two equal parts.
The first step of construction is to place the needle of compass at Y and draw an arc that intersects YX and YZ.
Hence, the correct option is option C.
Place the compass point on vertex Y and draw an arc that intersects YX and YZ
Answer:
29.7345 square units
Step-by-step explanation:
Area of the shaded part = Area of the rectangle - Area of the quarter circle
Area of the rectangle = Length × Width = 10 × 8 = 80 square units
Area of the quarter circle =
× π × r² (r for radius) = 0.25 × π × 8² = 50.2655 square units (answer rounded up to four decimal places)
Area of the shaded part = 80 square units - 50.2655 square units = 29.7345 square units
Answer:
its D
Step-by-step explanation:
3r+2(12r+7)<5r-8
3r+24r+14<5r-8
27r+14<5r-8
22<-22r
when you devide by a negative the signs flips so
22/-22>-22/-22r
-1>r
Beforehand let me apologize for my sloppy handwriting. I'm a lefty, so please deal with me. . Anyway, the equation you listed didn't really have a x, because a linear equation is y= mx+b, and anything with x is the slope. But I did see y and a number on one side, so I'm like maybe I can get these two alone. So here's what I did:
2y + 4=0
-4 -4 I subtracted 4 on both sides. Why because you would want "y" alone.
Next,
2y= -4
Now to get "y" alone you want to divide on both sides.
2y= -4/ 2
y= -2
Now you're probably thinking "how do you graph it? There's no "x" in the equation." Well, you just graph it. Since the answer is y= -2, you go to the y axis, look for -2, and place a line to indicate that is the equation. And to make it clear, remember y is the y-intercept.
I really do hope this helps you, if not message me. I'll be happy to help, and again I'm sorry for my handwriting!
A) profit/original price x100 =percentage profit
(Profit: 360-300=$60)
=60/300 x100
=20%
b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720
Profit without discount: 720-600= $120
120-100= $20 discount
20/720 x100 =2.78%
