Answer:

Correct choice is B

Step-by-step explanation:

Consider inscribed quadrilateral OPQR in the circle. In thes quadrilateral m\angle O=x^{\circ},\ m\angle P=y^{\circ},\ m\angleQ=z^{\circ},\ m\angle R=w^{\circ}.

By the Inscribed Quadrilateral Theorem, a quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary. Thus,

m\angle O+m\angle Q=180^{\circ},\\ \\m\angle P+m\angle R=180^{\circ}

or in terms of x,\ y, z,\ w:

x^{\circ}+z^{\circ}=180^{\circ},\\ \\y^{\circ}+w^{\circ}=180^{\circ}.

Hence, option B is true.

<h3>Answer:  D. 5 blinks</h3>

=========================================================

Explanation:

First we'll need to find out how long it takes for the ball to go from the pitcher to the batter.

It needs to travel 60.5 feet and does so at a speed of 121 ft/sec

distance = speed*time

time = distance/speed

time = (60.5 ft)/(121 ft per sec)

time = 0.5 seconds

In half a second, the ball is from the pitcher to the batter.

------------

An eye blink is 0.1 second which means we can form this equation

0.1 second = 1 blink

We multiply both sides by 5 to get the "0.1 second" to turn into "0.5 seconds".

So,

0.1 second = 1 blink

5*(0.1 second) = 5*(1 blink)

0.5 seconds = <u>5 blinks</u> which points us to choice D.

Serhud [2]

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

15^{2} +x^{2}=24^{2}

Then you square the numbers that you currently have:

225+x^{2}=576

Then subtract 225 from both sides to isolate the x:

x^{2} =576-225

This gives you the equation:

x^{2} =351

Then take the square root of both sides which gives you:

x=18.7349939952

Then round to the nearest whole number which gives you x=19
