I need help with this lol

How do we show where an inequality is true on the number line! 50 points!

Vinvika [58]

Usually, we use the number line to solve inequalities with the symbols, < , ≤ , > , and ≥ .(the second and last one was rather hard to find on my keyboard) In order to solve an inequality using the number line, though, just turn the inequality sign to an equal sign. Then, solve the equation. Next step, graph the point on the number line (remember to graph as an open circle if the original inequality was <, or >). The number line should now be divided into 2 regions, one to the left of the graphed point, and one to the right of said point.

After that, pick a point in both regions and "test" it, check to see if it satisfies the inequality when plugged in for the variable. If it does, draw a darker line from the point into that region, with an arrow at the end. That is the solution to the equation: if one point in the region satisfies the inequality, the entire region will satisfy the inequality.

I had to check back in an old textbook to remember all of that. Sorry about the earlier answer. That was rather foolish to do so without actually understanding the question.

31/6 as a mixed number

liubo4ka [24]

Hello there awesome brainly user!

To convert $\frac{31}{6}$ to a mixed number you have to divide 31/6 which equals 5 R 1 Remember that the remainder is the numerator and the whole number is 5. So, the mixed fraction is $5\frac{1}{6}$

For further info, message me

Thanks and have a good day.

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 115 km south and 112 km east. Mt. Rainier is locat

Mars2501 [29]

Answer:

5 minutes 4.8 seconds

Step-by-step explanation:

We can work this problem several ways. One is to determine the component of the distance from JBLM to the mountain that is in the direction the plane is flying. We can do that by finding the dot product of the vector to the mountain with the normalized direction vector of the airplane:

JA = JR•(JP/|JP|) . . . . . . where JR = (56, -40) and JP = (112, -115)

= (56, -40)•(112, -115)/√(112² +115²)

JA = 10872/√25769 ≈ 67.7268 . . . . km

__

At a speed of 800 km/h, this distance will be covered in ...

time = distance/speed

time = (67.7268 km)/(800 km/h) = 0.0846585 h

That's about 5 minutes, 4.8 seconds.

_____

In the attached diagram, J represents JBLM, R represents Mt. Rainier, A represents the point of closest approach, and P would represent the location of the airplane after 1 hour of flying time, (112, -115). In the above, we have used the names of these line segments/vectors.

nadya68 [22]

Answer:

B. srvut

Step-by-step explanation:

To name a polygon, or any shape, remember that you must name it so that each angle is in order. Basically, do not go from angle s to angle u, and instead go to angle stu or srvu.

Hope this helps :)
