Answer:
b= 352/3
or b= 117.33
Step-by-step explanation:
262-3x+85=-5
-3x+(262+85)=-5
simplify the arithmetic
-3x+347=-5
Group all constants on the right side of the equation
-3x+347=-5
Subtract from both sides:
-3x+347-347=-5-347
Simplify the arithmetic:
-3x=-5-347
-3x=-352
isolate the x
-3x=-352
Divide both sides by -3
-3x/-3}=-352/-3}
Cancel out the negatives
3x/3}=-352/-3
Simplify the fraction
x= -352/-3
Cancel out the negatives
x=352/3
The answers are B, C, and D.
I hope this helps, I have taken the quiz and those are the correct answers! :)
Answer: the exact perimeter of the figure is 53.68 cm
Step-by-step explanation:
The angle formed by the shaded sector is
360 - 90 = 270 degrees
We would determine the length of the arc formed by the shaded portion by applying the formula for length of arc which is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 8 cm
θ = 270 degrees
Length of arc = 270/360 × 2 × 3.14 × 8
= 37.68 cm
Perimeter of the figure is
Length of arc + radius + radius
It becomes
37.68 + 8 + 8 = 53.68 cm
