Answer:
5) 18.8 cm
7) 49.5 ft

Explanation:
The formula for arc length is S = θ * r

5) S = 18 cm * Pi/3 (60 degrees in radians)
S = 6 Pi cm
S ≈ 18.8 cm

7) S = 9 ft * 7 Pi / 4
S = 63 Pi ft / 4
S ≈ 49.5 ft

Length of arc=r $\theta$

$\\ \rm\Rrightarrow Area=18(\pi/3)=6\pi cm$

$\\ \rm\Rrightarrow Area=9(7\pi/4)=63\pi /4ft$

What does x equal to x/7 - 4 = -5

beks73 [17]

Answer:

x = -7

Step-by-step explanation:

So we are asked to find what x is equal to in the equation:

$\frac{x}{7}-4=-5$

In other words, we are asked to solve for x.

$\frac{x}{7}-4=-5$

Add 4 to both sides of the equation.

$\frac{x}{7}=-1$

Multiply both sides by 7.

x = -7

So we have solve the equation for x and have found that x = -7.

I hope you find my answer and explanation to be helpful. Happy studying.

One of the legs of a right triangle measures 6 cm and its hypotenuse measures 8 cm. Find the measure of the other leg. If necess

Vika [28.1K]

Well, this is a Pythagorean theorem problem. A^2 + B^2 = C^2, where C^2 is equal to the hypotenuse. 8 squared equals 64, so c^2 = 64 cm. The other leg can be represented by A^2, which is 36 cm. 36 + ? = 64. 64 - 36 = 28, so B^2 equals 28. Now, to find the measurement of the other leg, we need the square root of 28. The square root of 28 is 5.3 cm.

Your final answer is 5.3 cm.
