Answer 1

Answer:

1. -7

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides of the equation.

-3x = 16

divide both sides by -3

x = -7

(Sorry, I don't know what 2 is!)

Answers

Answer:

AE = CF .

Why?

BD acts as a shape bisector because it cuts the entire rectangle in half from points B and D.

Given that AE is perpendicular to BD, and CF is perpendicular to BD (which we know BD is a bisector), that means that both AE and CF are of equal length inside the rectangle.

Another way to look at it is:

AE = CF because they are technically just vertical angles, shifted and displaced in a weird way; it is a different representation of vertical angles, only distorted. (Don't use this as your answer though, it needs more context. I just want to make it look easier to comprehend.)

Look here in a square which is what I imagine that drawing is all the angles are 90 degrees. A rectangle would be knowing two angles is know all of them one way or another so fix your work and you should know the answer

Answer:

x = 200

Step-by-step explanation:

A rectangle (and any parallelogram) will always equal 360 degrees in angles. Technically, every angle has to equal 90 degrees for it to be a rectangle, just a side note.

Thus, 60 + 30 + 70 + x = 360

Solve for x.

60 + 30 + 70 + x = 360

160 + x = 360

x = 360 - 160

x = 200

Answers

Answer:

What you put does not make so much sense, so am solving on how I understand what is asking for.

Step-by-step explanation:

10c=13.71 -> I am assuming you want me to solve for c

c/10 = 13.71/10 -> divide 10 on both sides

c = 1.371 or 1371/1000

Answer: C = 1.371 or 1371/1000 or 1 371/1000

Military time is a 4 digit (base-10) integer with the following rules: The first two digits show the hour (between 00 and 23) and The last two digits show the minutes (between 00 and 59) There is no colon separating hours from minutes. Military time starts at 0000 in the morning and counts up When we get to the afternoon, we use 1300 for 1:00 PM and 2300 for 11:00 PM. When we get to midnight, the hour is 00 (not 24). TASK: Write a program that reads two times in military format and prints the number of hours and minutes between the two times (See example below). NOTE: Your program should consider the difference between the times IN THE SAME DAY. For example: The time difference between 2359 and 0000 is 23 hours and 1 minute (NOT 1 minute).Detailed Requirements Compose a written document (MS Word Document) describing your algorithm, feel free include a diagram if you like The program should prompt for two times separately, then print the duration of time between (see sample output below). The program should check the input for the correct military time format: . Make sure the hours are between 00 and 23. . Make sure the minutes are between 00 and 59 . If the validity check fails, it should print an appropriate error and prompt again. Your program should use io manipulators to produce military time with leading zeroes. e.g. 9 am should be printed 0900 (not 900). More points will be awarded to an implementation that can produce an accurate result regardless of the order of the inputs. Do not produce runtime errors that abruptly end your program (crash) Include descriptive comments, neat indentation, proper spacing for good readability, and appropriate and consistently named variables.
