A wheel has 11 spokes evenly distributed around the rim of the wheel. What is the measure, in radians, of the central angle form
2 answers:
Answer:
The angle between adjacent pairs of spokes is 2π/11 radian or 0.57 radian
Step-by-step explanation:
Consider the provided information.
Angle around the center is 360
360 is divided into 11 spokes, because
And with 11 spokes total number of angles would be 11. wheel has 11 spokes evenly distributed around the rim of the wheel.
As we know:
Since, the spokes are evenly distributed, the angle between any 2 spokes is:
Hence, the angle between adjacent pairs of spokes is 2π/11 radian or 0.57 radian

Answer:
(- , 4 )
Step-by-step explanation:
Given the 2 equations
3x + 8y = 28 → (1)
3x + 2y = 4 → (2)
Subtracting (2) from (1) term by term will eliminate the x- term
(3x - 3x) + (8y - 2y) = (28 - 4), that is
6y = 24 ( divide both sides by 6 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
3x + 8(4) = 28
3x + 32 = 28 ( subtract 32 from both sides )
3x = - 4 ( divide both sides by 3 )
x = -
Solution is (- , 4 )
Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to in
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
x° = - 3.5
x° =
Thus per hour; the temperature falls at the rate of
