Answer:
$170
Step-by-step explanation:
15% off means you pay 85% of the original price.
To find the price you will pay take the original price $200 and multiply that by .85 to figure out how much you will pay.
200 x .85 = $170
Answer:
X=3
X=-9
x=3/4
Step-by-step explanation:
First, find the perimeter of the circle
p = 2 × π × r
p = 2 × 3,14 × 19
p = 119.32
The perimeter of the circle is 119.32 cm
Second, find the central angle
Comparison of the central angle, full rotation angle, the arc, and the perimeter can be written as
angle/(full rotation angle) = arc/perimeter
angle = arc/perimeter × (full rotation angle)
Input the numbers
angle = arc/perimeter × (full rotation angle)
angle = 6/119.32 × 360°
angle = 6(360°)/119.32
angle = 2,160/119.32
angle = 18.1
The central angle would be 18.1°
Answer:
The two numbers can be -12 and 11, or 11 and -12.
Step-by-step explanation:
xy=-132
x+y=-1
-------------
x=-1-y
(-1-y)y=-132
-y-y^2=-132
-y^2-y-(-132)=0
-y^2-y+132=0
y^2+y-132=0
factor out the trinomial,
(y-11)(y+12)=0
zero property,
y-11=0, y+12=0,
y=0+11=11,
y=0-12=-12
x+11=-1 & x+(-12)=-1
x=-1-11=-12
x=-1-(-12)=-1+12=11
