my dad is 40 miles away at work...if he leaves work at 6:24pm...and travels at an average of 43 miles per hour...what time is he

ExtremeBDS [4]

If his speed is 43 mph, then it takes him 40/43 of an hour to go 40 miles.

An hour = 60 minutes.

40/43 of 60 minutes = 55.8 minutes. He gets home 55.8 minutes after 6:24 PM.

Which inequality represents all the solutions of -5x+5 > 160 - 10x?

Tcecarenko [31]

Answer:

x > 31

Step-by-step explanation:

Given

- 5x + 5 > 160 - 10x ( add 10x to both sides )

5x + 5 > 160 ( subtract 5 from both sides )

5x > 155 ( divide both sides by 5 )

x > 31

Find the angle [OA] makes with the positive x-axis if the x-coordinate of the point A on the unit circle is 0.222

EastWind [94]

By using the concepts of unit circle and trigonometric functions, we find that the angle OA, whose x-coordinate is 0.222, has a measure of approximately 77.173°.

<h3>How to find an angle in an unit circle</h3>

Unit circles are circles with radius of 1 and centered at the origin of a Cartesian plane, which are used to determine angles and trigonometric functions related to them. If we use rectangular coordinate system and the definition of the tangent function, we find that the angle OA is equal to:

$\tan \theta = \frac{\sqrt{1 - x^{2}}}{x}$

$\tan \theta = \frac{\sqrt{1-0.222^{2}}}{0.222}$

tan θ ≈ 77.173°

By using the concepts of unit circle and trigonometric functions, we find that the angle OA, whose x-coordinate is 0.222, has a measure of approximately 77.173°.
