What rational number is halfway between 1/2 and 1/3?
Answer:
5/12
Step-by-step explanation:
1/2 is equivalent to 6/12
1/3 is equivalent to 4/12
The number halfway between 6/12 and 4/12 is 5/12.
Answer:
5/12
Step-by-step explanation:
First we want to have common denominators, and since some of our answers are in twelfths anyways, we might as well go straight to those instead of multiplying to get common denominators of sixths.
Make the denominators of the two fractions we are given into twelfths
(-multiply 1/2 by 6 on the top and bottom to get 6/12, and multiply 1/3 by 4 on the top and bottom to get 4/12.
5/12 is perfectly halway between 6/12 and 4/12 so we have our answer! :)

Answer:
To convert m into km we divide a number by 1000
Step-by-step explanation:
To convert from metres to kilometres, divide by 1000 (since there are 1000 metres in each kilometre). To divide a whole number by 1000, put a decimal point at the end of the number and then move it three places to the left.

If 4/5 of the population of a certain town is
considered to be middle class and the population
of the town is 2,000, how many people are
considered middle class?
Hi! I'm happy to help!
Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)
2,000×4
8,000
8,000/5
Fractions are just a different way of putting division, so we can change this to a division problem:
8,000÷5=
1,600
1,600 of the people are middle class.

Answer:
a) slope = -765 jobs per year
b) j = -765y +1582855 . . . . jobs in year y
c) 38,320 jobs in 2019
Step-by-step explanation:
a) We can define the variables y and j to represent the year number and the number of jobs, respectively. Then we are given 2 points:
(y, j) = (2012, 43675) and (2017, 39850)
The slope of the relation is ...
m = Δj/Δy = (39850 -43675)/(2017 -2012) = -3825/5 = -765
__
b) Using the point-slope form of the equation of a line, we can model the relation between years and jobs as ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
For m = -765 and (h, k) = (2012, 43675), the model gives ...
j -43675 = -765(y -2012)
j = -765y +1582855 . . . . . . . rearrange to slope-intercept form
__
c) For y = 2019, the number of jobs is modeled to be ...
j = -765(2019) +1582855 = -1544535 +1582855
j = 38,320 . . . . . jobs in 2019
_____
Additional comment
Quite often for problems of this sort, we let the time variable represent "years after <some reference year>". Here, it would be convenient to use 2012 as the reference year. The the equation would be j = -765y +43675, and the "j-intercept" would have the sensible value of 43675 at "year 0" (or 2012).
The equation we show is technically correct, but has no meaning for year values less than 2012. Especially, we know for sure there were not 1.6 million jobs in information in Indiana at the beginning of the Common Era. Indiana didn't exist until 1816.

Step-by-step explanation:
sqrt(50) - irrational. sqrt(50) = sqrt(25×2) = 5×sqrt(2).
sqrt(2) is the prime example of an irrational number (infinite positions after the decimal point, no repeating patterns).
3.45656565656... - rational. although it is infinite, it has had a repeating pattern that allows us to write it as fraction.
0 - rational. as every integer or whole number.
sqrt(4/9) = 2/3 - rational as expressed as fraction.
0.38 - rational. it is a finite decimal number, and can be easily expressed as fraction (like 38/100).
sqrt(81) = 9 - rational. again, as every integer or whole number.
2pi - irrational. pi is a prime example of an irrational number (infinite and no repeating pattern). not possible to write as fraction. Any combination of pi is also irrational.
sqrt(1.69) = 1.3 - rational. finite decimal that we can easily write also as fraction (like 13/10).
sqrt(2/9) = sqrt(2)/3 - irrational, as sqrt(2) is a prime example for an irrational number. any combination with an irrational number is an irrational number.
A submarine is at 200 meters below sea level to begin its mission. Then, it dives to a depth of 4 times its initial depth.Where is the submarine now located
Answer:
1000 meters below sea level
Step-by-step explanation:
Since the submarine dives at a depth of 4 times 200 meters, then it dives 800 meters.
Sso the submarine now is at 200 meters + 800 meters =1000 meters below sea level.

Absolute Value Equation step by step
Answer:
x = -3/2
Step-by-step explanation:
- |2x + 4| + 3 = -4Remove the absolute value, since you can't solve anything inside. Everything becomes negative due to the negative sign on the outside.
-2x - 4 + 3 = -4Combine -4 + 3, which results in -1.
-2x - 1 = -4Move -1 over to the other side through adding, which results in -3.
-2x = -3Divide -2 by -3, which doesn't go equally, so you leave it.
x = -3/2Go as far as you need for an answer, all will work.

Find the missing angle and name the other three given angle.
PQR=___
Name:___________
________________
________________
Answer:
Step-by-step explanation:
The angles between the parallel sides add up to 180 degrees.
So 180-70 = 110 degrees.
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
Let,
The unknown angle measure be x°.
We know that,
Sum of all angles of a Quadrilateral measures 360°.
So,
⇒∠QPR + ∠PSR + ∠SRQ + ∠RQP = 360°
⇒ 120° + 60° + 70° + x° = 360°
⇒ 180° + 70° + x° = 360°
⇒ 250° + x° = 360°
⇒ x° = 360° - 250°
⇒ x° = 110°
Therefore, the names of the angles & their values will be,
⇒∠QPR = 120°
⇒∠PSR = 60°
⇒∠SRQ = 70°
⇒∠RQP = 110°

1.) Find the length of the arc of the graph x^4 = y^6 from x = 1 to x = 8.
2.) Find the length of arc with parametric equations x = 3 cos t, y = 3 sin t from t=0 to t=⛩
I believe I've addressed (1) in another question of yours (24529718).
For (2), the arc length of the curve parameterized by x(t) = 3 cos(t ) and y(t) = 3 sin(t ) over 0 ≤ t ≤ π is
[tex]\displaystyle \int_0^\pi \sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2 + \left(\frac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt[/tex]
We have
[tex]\dfrac{\mathrm dx}{\mathrm dt} = -3\sin(t) \text{ and }\dfrac{\mathrm dy}{\mathrm dt} = 3\cos(t)[/tex]
so that the integral reduces to
[tex]\displaystyle \int_0^\pi \sqrt{9\sin^2(t) + 9\cos^2(t)}\,\mathrm dt = 3\int_0^\pi\mathrm dt[/tex]
since [tex]\cos^2(t)+\sin^2(t)=1[/tex] for all t. The remaining integral is trivial:
[tex]\displaystyle 3\int_0^\pi\mathrm dt = 3t\bigg|_0^\pi = 3(\pi-0) = \boxed{3\pi}[/tex]
4. A model of the Elffel Tower that was
purchased in a gift shop is 30 -
inches tall. The actual height of the
Elffel Tower is 1000 feet, or 12,000
inches. What scale factor was used to
make the model?
Answer:
400
Step-by-step explanation:
To find the scale factor, you need to find out how much the initial value was multiplied by to get the new value. To do that, you need to divide the new value by the initial value. Make sure the units are the same; don't divide 1000 feet by 30 inches!
[tex]\frac{new}{initial} = \frac{12000}{30}=400[/tex]

Answer:
x = 1.129 (Table I)
x = 13 (Table II)
Step-by-step explanation:
Log and exponential functions are inverses of each other. For each ordered pair (a, b) in Table I, there could be an ordered pair (b, a) in Table II. (Some corresponding pairs are missing.)
All you have to do here to locate the missing value is to find the corresponding pair in the other table.
(x, 9) in Table I ⇔ (9, 1.129) in Table II . . . . . . . x = 1.129
(x, 1.318) in Table II ⇔ (1.318, 13) in Table I . . . . x = 13

Find the equation of the line through (9,-7) that is perpendicular to the line y = -x/2 - 2
Answer:
[tex]y=2x-25[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
Perpendicular lines always have slopes that are negative reciprocals, such as 2 and -1/2, 3/4 and -4/3.
1) Determine the slope (m)
[tex]y = \displaystyle -\frac{x}{2} - 2[/tex]
Rewrite the given line:
[tex]y = \displaystyle -\frac{1}{2}x - 2[/tex]
Now, we can clearly identify the slope to be [tex]\displaystyle-\frac{1}{2}[/tex]. Because perpendicular lines always have slopes that are negative reciprocals, the slope of the line we're currently solving for is therefore 2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=2x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=2x+b[/tex]
Plug in the given point (9,-7) and solve for b:
[tex]-7=2(9)+b\\-7=18+b\\b=-25[/tex]
Therefore, the y-intercept is -25. Plug this back into [tex]y=2x+b[/tex]:
[tex]y=2x+(-25)\\y=2x-25[/tex]

A spreadsheet is made for this sort of computation. Copy the data to a spreadsheet. Use the "text to columns" feature to separate the data from the dates, and to put the A and B data in different columns.
Then use the spreadsheet built-in covariance and correlation functions to find the values of interest.
In the attachment, we have hidden the middle 50 rows of data to make it easier to select the range of data required for the functions we're using. (In many spreadsheets, you can name a range, so you only need to refer to it by name.)

Graphing calculators and spreadsheets are essential technology tools. While it can take a bit of study to learn all of the features in depth, you can usually learn enough in a few minutes to be able to make use of these tools to solve many problems. In most cases, videos are available.
The Go.ogle Sheets application works in a browser and is free. That's what was used here. Other free office-type applications (word processor, spreadsheet, and so on) are also available for download to computer, tablet, or phone. (I find it tedious to use these apps on a phone.)
