Find the perimeter of the figure to the nearest hundredth.
1 answer:
Answer:
28.87 inch
Step-by-step explanation:
The perimeter of a figure is the sum of the length of the boundary sides of the figure surrounding it.
For the above figure the perimeter is the sum of the three sides of the rectangle and circumference of the semicircle.
Diameter of the semicircle forming in the figure is 5 inch(given)
Circumference of the semicircle forming in the figure =
:

Answer:
x=1, y=7
Step-by-step explanation:
y = -3x + 10 - first equation
y=-3x + 4 - second equation
rearrange the expression to
-3x-y= -10
3x-y= -4
pick an equation and simplify; lets pick the second equation
3x-y= -4
divide 3 by both sides
x= - third equation
substitute the value of x into an equation; lets pick the first equation
-3x-y= -10
-3- y = -10
simplify. -3 cancels 3 so we are left with
-1(-4+y)-y = -10
simplify
4-y-y= -10
4-2y= -10
subtract 4 from both sides
-2y= -10-4
-2y= -14
divide -2 by both sides
y=7
substitute the value of y, (y=7) in an equation, we are using the second equation
3x-y= -4
3x-7= -4
3x = -4+7
3x= 3
divide 3 by both sides
x=1
so the answer is x=1, y=7
