Answer:
Equation I: C=2*3.14*r
Step-by-step explanation:
A linear equation is an equation whose highest exponent on the variable is 1.
C=2*3.14*r.................Exponent of 1
A = 3.14*r^2...............Exponent of 2
A = 3.14*r^2...............Exponent of 3
Answer:

Step-by-step explanation:
the arc length of a circle is calculated as
arc = circumference of circle × fraction of circle
(5)
circumference (C) is calculated as
C = 2πr ( r is the radius )
here diameter = 12 , then r = 12 ÷ 2 = 6
C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )
(6)
JK = 2πr × 
= 2π × 7 × 
= 14π × 
=
≈ 9.2 in ( to the nearest tenth )
(7)
7.5 = 2πr ×
7.5 = 2πr ×
( multiply both sides by 3 to clear the fraction )
22.5 = 2πr ( divide both sides by 2π )
r =
≈ 3.6 ft
Answer:
3x -4y = 30
Step-by-step explanation:
Multiply the given equation by the least common denominator of the fractions, 6.
... (1/2x)·6 -(2/3y)·6 = 5·6
... 3x -4y = 30 . . . . . . simplify
Answer: Length = 40 inches
Width = 20 inches
Step-by-step explanation:
Let the width of the package be represented by x.
Since the length of the package must be twice its width, therefore the length will be: = 2 × x = 2x
Since the sum of the dimensions equals 60 inches. This will then be:
x + 2x = 60.
3x = 60
x = 60/3
x = 20
Therefore, the width = 20 inches
Length = 2x = 2 × 20 = 40 inches
The dimensions should be 40 by 20 inches.
