Answer:

$\frac{1}{2}$ is the answer

Step-by-step explanation:

First we need to substitute X and Y with their respective numbers

$3\cdot \:6+\frac{6}{-4}-\left(-4\right)^2$

Then, following PEMDAS, We just need to simplify

$18+\frac{6}{-4} -16$

$16.5-16=0.5=\frac{1}{2}$

Ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .

bulgar [2K]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

$\frac{90}{6}$ = $\frac{6x}{6}$

15 = x

Therefore, the x is 15.

A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi.

Brut [27]

Answer:

The area of this plate is $36.31\ \text{inches}^2$ .

Step-by-step explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

$C=2\pi r$

r is radius of circular shape

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{21.4}{2\times 3.14}\\\\r=3.4\ \text{inches}$

Area of this plate is given by :

$A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2$

So, the area of this plate is $36.31\ \text{inches}^2$ .
