A textbook store sold a combined total of 288 history and psychology textbooks in a week. The number of history textbooks sold was two times the number of psychology textbooks sold. How many textbooks of each type were sold
Answer:
x=96 and y=192
Step-by-step explanation:
x+y=288 and 2x=y
plug y in and solve for x
x+2x=288
3x=288
x=96
plug x back in and solve for y
2(96)=y
y=192

Taylor’s domain is and range is Thomas domain is and range is
Step-by-step explanation:
please send your teacher some nice greetings from me, as this problem description is very incomplete.
we have to guess and assume a few things.
I assume that for both people there is a function describing how many objects (x and y) are sewn after a given amount of time (t).
and we are only looking at a single work day. and not a week or a year.
so,
x = Taylor(t)
y = Thomas(t)
remember that the domain is the interval or set of valid values for the input variable (the argument of the function). in our case here this is t.
and the range is the interval or set of valid values for the output variable (x and y).
so, the domain for Taylor is the interval of valid work time
[0, 8] in hours. we could also define it in minutes to not get confused, and that would be [0, 480] in minutes.
Taylor's range is then (as he can do 6 per hour = 1 every 10 minutes)
[0, 8×6] or [0, 480/10] = [0, 48].
the domain for Thomas is his valid work time [0, 10] in hours or [0,600] in minutes.
Thomas's range is then (2 per hour or 1 every 30 minutes)
[0, 10×2] or [0, 600/30] = [0, 20]
please pick for the domain the scale (hours or minutes) your teacher prefers. I suspect hours due to the phrasing, but just in case I showed you both.
Domain defines the input interval and range defines the output interval.
Here for both Taylor and Thomas Domain is how many hours they have worked and range for both of them is how many hats and mittens they have produced in their working hour.
Whatis domain and range ?Domain defines the input interval and range defines the output interval corresponding to the domain interval.
In the given question domain of Taylor is (0,8) and each hat takes 10 mins or 1/6 hours
in 1/6 hours Taylor makes 1 hat
so, in (1/6 x 6) = 1 hour taylor will make ( 1 x 6 ) = 6 hats
so in 8 hours Taylor will make (8 x 6) = 48 hats
Range of taylor = (0,48). .(as in 0 hour he will make 0
hats )
Domain of Thomas is 10 hours = (0,10)
Every pair of mittens take 30 minutes or 1/2 hour
so , In 1/2 hour Thomas makes 1 pair of mittens
In(1/2 x 2 ) = 1 hour he will make (1 x 2)= 2 pair of mittens.
In 10 hours Thomas will make (2 x 10 ) = 20 pair of mittens.
The range of Thomas is (0,20). .(as in 0 hour he can make no
pair of mittens)

A recent poll in your state shows that 25% of the vehicles are SUV’s and 10% are trucks. The poll counted 5 million SUV’s. How many of the vehicles did they look at in total?
Answer:
20 million
Step-by-step explanation:
5 million SUVs are 25% of the total number of vehicles.
0.25x = 5,000,000
x = 20,000,000
Answer: 20 million
The question is an illustration of proportions.
A total of 20 million vehicles were looked into
The proportions are given as:
[tex]SUV = 25\%[/tex]
[tex]Trucks= 10\%[/tex]
Let the total number of vehicles be v.
The number of SUVs is given as 5 million.
So, we have:
[tex]SUV = 25\% \times v[/tex]
Substitute 5 million for SUV
[tex]5\ million= 25\% \times v[/tex]
Express the percentage as decimal
[tex]5\ million= 0.25 \times v[/tex]
Divide both sides of the equation by 0.25
[tex]20\ million = v[/tex]
Rewrite the equation as
[tex]v =20\ million[/tex]
Hence, 20 million vehicles were looked into

what is the slope of a line parallel to the line on the graph?
Answer:
3/4
Step-by-step explanation:
To find the slope of a line parallel to this line, we first need to find the slope of this line. Using rise/run, you get that the slope is 6/8 which simplifies to 3/4.
The slope of any two parallel lines always is the same so the slope of a line parallel to the one given would be 3/4.

a line that is parallel to y=-3x+2 and contains the point (3,-3)
Answer:
y = -3x + 6
Step-by-step explanation:
Two lines that are parallel will have the same slope. All we need to do is find the new y-intercept.
-3 = -3(3) + b
-3 = -9 + b
6 = b
Now we can input the stuff we know and solved for back into the original formula [ y = mx + b ].
y = -3x + 6
Best of Luck!
A parallel line means our new line will have a slope equal to the original line.
The original line is in slope-intercept form, y = mx + b, where m is the slope and b is the value of the y-intercept. This tells us that the slope we want to use is m = -3
By using a slope of -3, with the given point (3,-4), we can now use the point-slope formula to find our new line.
Point-slope formula: y - y1 = m(x - x1) where m is the slope and the line passes through the point (x1,y1)
Combining our point and slope, we get:
y + 4 = -3(x - 3)
If we wish, we can rearrange this by distributing on the right hand side.
y + 4 = -3x + 9
We can then subtract 4 from both sides to get our answer in slope-intercept form
y + 4 - 4 = -3x + 9 - 4
y = -3x + 5

Two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube. One particle travels 97 cm in the 1st 2 seconds, 93 cm in next 2 seconds , 89 cm in another next 2 seconds, etc. The other particle travels 49 cm in the 1st 2 seconds, 47 cm in the next 2 seconds , 45 cm in another next 2 seconds, etc. Find how long it takes for the particles to meet and hence, determine the distances travelled by each particle.
This shows that it will take the particle 23 secs to meet.
The distance travelled by each particle is 50cm
If two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube,
The first particle distances are 97cm, 93cm, 89cm... every 2secs
This form an arithmetic sequence and the nth term is expressed as:
Tn = a + (n - 1)d
a is the first term = 97
d is the common difference = 4
Substitute
Tn = 97+(n - 1)(4)
Tn = 97 + 4n -4
Tn = 4n + 93
Similarly for the distances 49 cm, 47 cm, 45cm .....
This also forms an arithmetic sequence and the nth term is expressed as:
Tn = a + (n - 1)d
a is the first term = 49
d is the common difference = 2
Substitute
Tn = 49+(n - 1)(2)
Tn = 49 + 2n -2
Tn = 2n + 47
For the particles to meet, this means that 4n + 93 = 2n + 47
4n - 2n = 47 - 93
2n = -46
n = -23
This shows that it will take the particle 23 secs to meet.
To get the distance travelled by each particle
Tn = 4n + 93
T2 = 4(2) + 93
T2 = 101
For the other sequence;
Tn = 2n + 47
T2 = 2(2) + 47
T2 = 51
Taking the difference;
D = 101 - 51 = 50cm
Hence the distance travelled by each particle is 50cm
