Answer:
B/ x=4
Step-by-step explanation:
Just take 2x to another side to be neg-, the same thing with 4 , then divide it both sides by 4 to get the answer.
Answer:
18.85 rounded
Step-by-step explanation:
The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
L / Θ = C / 2π
As circumference C = 2πr,
L / Θ = 2πr / 2π
L / Θ = r
We find out the arc length formula when multiplying this equation by Θ:
L = r * Θ
Hence, the arc length is equal to radius multiplied by the central angle (in radians).
Answer:
D
Step-by-step explanation:
rise over run!
In any form, the difference is -9 hundredths.
The hundredths place is the second to the right of the decimal point.
0.01 . . . . one hundredth
0.10 . . . . ten hundredths (also known as one tenth)
In ten hundredths, the 1 digit is moved one place to the left, indicating its value is 10 times its value in 0.01.
The difference is 0.01 -0.10 = -0.09, negative nine hundredths.
