does anyone know how to solve this? and if so can you put an explanation? ive been struggling with this question for a while
Answers
Answer:
x = 31
Step-by-step explanation:
So, the angle of a line is 180 degrees. This is a very important fact, because this means that (5x - 16) + (x + 10) = 180 degrees.
Note: The parenthesizes are not needed, but I put them there to symbolize the adding of those two angles that make up the line.
Adding like terms, we get:
6x - 6 = 180
Move the -6 over to the right side.
We get:
6x = 186
Dividing both sides by 6, we get the value of x:
x = 31

3/4 + 2/3 using fractions
Answers
Step-by-step explanation:
Lowest common multiple (LCM) of 4 and 3 = 12.
Therefore 3/4 + 2/3
= 9/12 + 8/12
= 17/12 or 1 5/12.
Answer:
1 5/12
Step-by-step explanation:
To do this, we need to find the LCM of 4 and 3. The LCM of 4 and 3 is 12. Now, since 4x3 is 12, we multiply 3/4 by 3/3 to get 9/12. Now, we multiply 2/3 by 4/4 (since 3x4 is 12) to get 8/12. Now, we add only the top numbers to get 17/12. To simplify this, we divide 17 by 12 (check attached screenshot). The quotient (the answer) becomes the whole number, the divisor (12) becomes the denominator, and the remainder (5) becomes the numerator. This gets us 1 5/12.

If cinnamon sells for $1.80 per ounce, nutmeg sells for $1.60 per ounce, and cloves sell for $1.40 per ounce, what should be the price per ounce of the mixture. math problem answer
Answers
Answer:
$1.65
Step-by-step explanation:
Given that:
Batch mixture :
Cinnamon - 200 ounces
Nutmeg - 100 ounces
Cloves - 100 ounces
Cost of Seasoning mix :
Cinnamon - 1.80 per ounce
Nutmeg - 1.60 per ounce
Cloves - 1.40 per ounce
Price per ounce of mixture :
Let the price per ounce of mixture = x
Total ounce of mixture = (100 + 100 + 200) = 400 ounces
Σ(ounce * cost) = total ounce * cost of mixture
(200*1.80)+(100*1.60)+(100*1.40) = 400 * x
$360 * $160 * $140 = 400x
$660 = 400x
x = $660 / 400
x = $1.65
Price per ounce of mixture = $1.65

The IRS was interested in the number of individual tax forms prepared by small accounting firms. The IRS randomly sampled 50 public accounting firms with 10 or fewer employees in the Dallas-Fort Worth area. The following frequency table reports the results of the study.
Number of Clients Frequency
25 up to 40 3
40 up to 55 11
55 up to 70 24
70 up to 85 8
85 up to 100 4
Estimate the mean and the standard deviation. Round squared deviations to the nearest whole number and the final answer to 2 decimal places.
Answers
Answer:
Estimates of the number of individual tax forms prepared by small accounting firms:
1. Mean = 10
2. Standard deviation = 7.56
Step-by-step explanation:
a) Data and Calculations:
Number of Clients Frequency Mean Diff Squared Deviation
25 up to 40 3 -7 49
40 up to 55 11 1 1
55 up to 70 24 14 196
70 up to 85 8 -2 4
85 up to 100 4 -6 36
Sum 50 286
Mean of frequencies = 10 (50/5) 57.2 (286/5)
Standard deviation = square root of 57.2 = 7.56
b) The IRS can obtain the mean value of the number of individual tax forms prepared by small accounting firms by dividing the sum of the frequencies by the numbers (50/5). Similarly, the IRS can calculate the standard deviation of the number of individual tax forms prepared by small accounting firms, which measures how spread out the data is about the mean value, by working out the mean of the frequency numbers. Then subtract the mean for each number and square each result. Add up the squared differences and divide by the number to get the mean. Finally, take the square root of the mean differences.

a. How could we find the perimeter below about the quadrilateral?
b. How might we calculate the area of this figure?
c. It looks like it might be a rectangle. What can we do to help us decide if it's a rectangle or a parallelogram?
Answers
Before we begin, note that we need to use the distanse formula for everything to reach our conclusion. With that being said, here we go:
[tex]\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d[/tex]
Using the ordered pairs [tex]\displaystyle [3, -3][/tex] and [tex]\displaystyle [4, -2][/tex] for instanse:
[tex]\displaystyle \sqrt{[-3 + 4]^2 + [3 - 2]^2} = \sqrt{1^2 + 1^2} = \sqrt{2}[/tex]
Now, sinse the distanse between [tex]\displaystyle [3, -3][/tex] and [tex]\displaystyle [4, -2][/tex] is [tex]\displaystyle \sqrt{2}[/tex] units, then the distanse between [tex]\displaystyle [1, 1][/tex] and [tex]\displaystyle [0, 0][/tex] ALSO has to be [tex]\displaystyle \sqrt{2}[/tex] units. By definition, lettre c has already been answered for you because sinse it is a rectangle, if the two short sides are congruent, then the two long sides ALSO have to be congruent, but just in case you want to be sure [you do not trust your instincts], just simply re-use the distanse formula.
Using the ordered pairs [tex]\displaystyle [1, 1][/tex] and [tex]\displaystyle [4, -2][/tex] for instanse:
[tex]\displaystyle \sqrt{[-1 + 4]^2 + [-1 - 2]^2} = \sqrt{3^2 + [-3]^2} = \sqrt{9 + 9} = \sqrt{18} = 3\sqrt{2}[/tex]
So there you have it. The length of both of the long sides is [tex]\displaystyle 3\sqrt{2}[/tex] units.
Now that we cleared all of that up, we can now find the perimetre and area of this rectangle:
[tex]\displaystyle 2w + 2l = P[/tex]
[tex]\displaystyle 2[\sqrt{2}] + 2[3\sqrt{2}] = 2\sqrt{2} + 6\sqrt{2} = 8\sqrt{2}[/tex]
The perimetre of this rectangle is [tex]\displaystyle 8\sqrt{2}[/tex] units.
[tex]\displaystyle wl = A[/tex]
[tex]\displaystyle [\sqrt{2}][3\sqrt{2}] = [3][2] = 6[/tex]
The area of this rectangle is [tex]\displaystyle 6[/tex] squared units.
You have now found what you were looking for.
** All rectangles are parallelograms because they both have two pairs of parallel and congruent sides, while vice versa is falce because a parallelogram does not have four congruent right angles, so it is safe to say that this is both a rectangle AND parallelogram, sinse the picture displayed is a rectangle.

Answer:
a) compute and add up the side lengths
b) multiply length by width
c) compare the slopes of adjacent sides
Step-by-step explanation:
a) The perimeter of any figure is the sum of the lengths of its sides. It can be computed for a rectangle or parallelogram by adding the lengths of adjacent sides and multiplying the sum by 2.
In this graph, each grid square is 1/2 unit. The width of the rectangle is the diagonal of a square that is 1 unit on a side, so is √2 units. The length is 3 times that, so the perimeter is ...
P = 2(L+W)
P = 2(3√2 +√2) = 8√2 . . . . perimeter of the rectangle in units
__
b) The area is the product of the length and width.
A = LW
A = (3√2)(√2) = 6 . . . . area of the rectangle in square units
__
c) Each side lies on the diagonal of a unit square. The diagonals of a square are perpendicular, so the sides of this parallelogram are perpendicular. That means the figure is a rectangle.
The basic idea is to look at adjacent sides to see if they are perpendicular. Here, we have determined that using the properties of a square. One could compute "rise"/"run" for each side to see of the values are opposite reciprocals.
origin to B: rise/run = 1/1 = 1
B to C: rise/run = -3/3 = -1
Each of these values is the opposite reciprocal of the other: 1 = -1/-1.

x = 90 (verified answer) ✅Step-by-step explanation:
There are 360° of measure in a quadrilateral. By the definition of a parallelogram, we know that the angle opposite the labeled angle will have the same measure as that labeled angle.
So, 12x + 12x + 8x + 8x = 360
Simplifying all the x's gives us:
40x = 360
Divide by 40
x = 90
Now, we check this
40 (90) = 360
360 = 360 ✅
