What is the measure of angle x? Enter your answer in the box.

41.5 degrees

There are 180 degrees in a semicircle. So if if 56 and 41 degrees are taken, that means that 83 degrees are left. One the angle is on one side of 'x' is the same as the other side. So that means that the 83 degrees that are left are split evenly in two. Therefore 'x' is 41.5 degrees. The equation would look like the following.

180-((angle)+(if other angles)= Left over degrees

Your specific equation looks like the following.

180-   97    = 83    83/2=41.5

Add 2 to both sides.

2x - 2 + 2 = -5 + 2 

2x = -3 

Divide both sides by 2

To find coterminal angles you would add (or subtract) 360 degrees until you
get within the range you need.
You use 360 because the revolution of a full circle is 360 degrees.
403 + 360 = 763 degrees
403 - 360 = 43 43-360 = -317 degrees

QUESTION POSTED AT 24/02/2020 - 12:30 AM

The sum of three consecutive integers is 75. Find the integers

Let the first integer be x
adding one to x (to represent the next integer) you get x + 1
adding two to x to get the next integer you get x + 2
the expression that represents three consecutive integers is x + (x + 1) + (x + 2)
Now we need to set this equal to 75 and solve.
x + (x + 1) + (x + 2) = 75
3x + 3 = 75
subtract 3 from both sides
3x + 3 - 3 = 75 - 3
3x = 72
to clear the multiplication by 3, divide both sides by 3
3x/3 = 72/3
x = 24
x + 1 = 25
x + 2 = 26
24, 25, 26 are the three integers

1/2(4x-9)=2x+8 A. exactly one real solution, B. no real solutions C. infinite real solutions D. exactly one real solution,

Let us first try and solve this equation to see how many solutions are for this equation.

We need to have x on one side of the equation and everything on the opposite side of x.

1/2(4x - 9) = 2x + 8 ; Start
2x - 4.5 = 2x + 8     ; Distribute the 1/2 across 4x and -9
2x = 2x + 12.5        ; Add 4.5 to each side of the equation
0 = 12.5                  ; Subtract 2x from each side of the equation

As we can clearly see, this equation has 0 answers.

QUESTION POSTED AT 24/02/2020 - 12:25 AM

How many of the numbers from 10 through 92 have the sum of their digits equal to a perfect​ square?

All the numbers in this range can be written as 10d_1+d_0 with d_1\in\{1,2,\ldots,9\} and d_2\in\{0,1,\ldots,9\}. Construct a table like so (see attached; apparently the environment for constructing tables isn't supported on this site...)

so that each entry in the table corresponds to the sum of the tens digit (row) and the ones digit (column). Now, you want to find the numbers whose digits add to perfect squares, which occurs when the sum of the digits is either of 1, 4, 9, or 16. You'll notice that this happens along some diagonals.

For each number that occupies an entire diagonal in the table, it's easy to see that that number n shows up n times in the table, so there is one instance of 1, four of 4, and nine of 9. Meanwhile, 16 shows up only twice due to the constraints of the table.

So there are 16 instances of two digit numbers between 10 and 92 whose digits add to perfect squares.

Tom has a collection of 30 CDs and Nita has a collection of 18 CDs. Tom is adding 1 CD a month to his collection while Nita is adding 5 CDs a month to her collection. Find the number of months after which they will have the same number of CDs. Show your work.

30 + 1x = 18 + 5x
subtract 18 from both sides
30 - 18 + 1x = 18 - 18 + 5x
12 + 1x = 5x
subtract 1x from both sides
12 + 1x - 1x = 5x - 1x
12 = 4x
To clear the multiplication by 4, divide both sides by 4
12/4 = 4x/4
3 = x
It will take 3 months until they have the same amount of CD's
They will each have 33 CD's

QUESTION POSTED AT 24/02/2020 - 12:15 AM

Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x? Drag and drop the equation into the box.

Answer:

1. 52° + x° + 67° = 180°

2.  x° + 22° = 90°

Step-by-step explanation:

1. In the first figure,

Since the angles given are supplementary angles i.e. their sum is 180°

So, we get,

52° + x° + 67° = 180°

i.e. x° = 180° - 119°

i.e. x° = 61°

Thus, the expression to find the value of x is 52° + x° + 67° = 180°.

2. In the second figure,

Since the angles given are complementary angles i.e. their sum is 90°

This gives us,

x° + 22° = 90°

i.e. x° = 90° - 22°

i.e. x° = 68°

Hence, the expression to find the value of x is x° + 22° = 90°
