Answer:

10.99 feet

Step-by-step explanation:

The arc length when an angle of 360° is made is the perimeter of the circle.

Perimeter = π*Diameter = π*30 = 94.25 ft

To know the arc length when an angle of 42° is made, we need to use the following proportion

94.25 ft / x ft = 360° / 42°

x = 42/360*94.25

x = 10.99 ft

What is the solution of the equation (x – 5)2 + 3(x – 5) + 9 = 0? Use u substitution and the quadratic formula to solve.
Vitek1552 [10]
(X-5)2+3(X-5)+9 = 0
let expand the equation
(x)x2-(5)x2 + 3(x)-3(5) + 9 = 0
2x-10+3x-15+9=0
collect like terms
2x+3x-10-15+9 =0
5x-10-6 =0
5x-16=0
5x=0+16
5x=16
divide both side by 5 we have
x=16/5

In ΔTUV, the measure of ∠V=90°, the measure of ∠T=54°, and VT = 40 feet. Find the length of UV to the nearest tenth of a foot.
Natali5045456 [20]
Tan T = UV/VT
UV = VT tan T = 40 tan 54
UV = 55.055 ft —> 55.1ft

Enter the simplified form of the complex fraction in the box.
Ket [755]

The problem is:

\frac{\frac{3}{x}+\frac{1}{4}}{1+\frac{3}{x}}

We now do L.C.M. of numerator and add, also do L.C.M. of denominator and add together:

\frac{\frac{12+x}{4x}}{\frac{x+3}{x}}

Dividing by a fraction is same as multiplying by its reciprocal, so we have:

\frac{12+x}{4x} * \frac{x}{x+3} \\

x cancels out, so can multiply and write:

\frac{12+x}{4} * \frac{1}{x+3} \\=\frac{12+x}{4x+12}

This is the simplified form.


ANSWER: \frac{12+x}{4x+12}
