The answer to this is 40 E, because you have to subtract 10 from both sides...
50 - 10 = 40
By knowing the properties of circles, the circle with a <em>central</em> angle ACB of 48° and the <em>arc</em> length AB is 144 inches has a circumference of 1080 inches.
<h3>How to determine the circumference</h3>
According to the <em>Euclidean</em> geometry, the <em>circular</em> arc (s), in inches, is directly proportional to the <em>central</em> angle (θ), in radians:
s = θ · r (1)
Where r is the radius of the circle, in inches. Please notice that the arc is directly proportional to the <em>central</em> angle and that the circumference is determined for a <em>central</em> angle of 360° (2π). Hence, we can determine the circumference of the circle by using the following relationship:
s/144 in = 360°/48°
s = (144 in) · (360°/48°)
s = 1080 in

Area of square = 64cm²
Length of one side of square=?
<u>Let,</u>
side of square = x
Now,
<u>Area of square = (x)²</u>
To answer the question above, convert the given displacement in revolutions to radians. The conversion factor is 1 revolution is equal to 6.28 radians.
(1.9 rev) x (6.28 radians / 1 rev) = 11.932 radians
Thus, the closest to this value is 11.9 and the answer is the second choice.
Answer:
5x-4=11
Step-by-step explanation:
so you multiply 5 times x (a number) and subtract 4 and it equals to 11
