B. The gains of the industrial revolution should be shared by all members of society. C. Governments have no right to restrict the actions of businesses or customers.
D. A government should restrict the number of imports and exports to protect its gold reserves.
Answers
Answer:
A
Step-by-step explanation:
:)Answer:
B. The gains of the industrial revolution should be shared by all members of society.
Step-by-step explanation:
Communists were opposed to the power that the wealthy bourgeoisie had, who controlled the means of production.
Instead, Communists wanted the proletariat (working class) to control the means of production, in order to create a more even distribution of wealth and power in society.
So, they supported making the Industrial Revolution's benefits shared by society.
Utopian socialists also would support this, as they also supported public ownership of the means of production.
The correct answer is B.

The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)
What is Rotation?A rotation is a type of transformation that rotates each point in a figure a specific number of degrees around a particular point.
90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y) 270° clockwise rotation: (x,y) becomes (-y,x)When we rotate a point around the origin by 90° clockwise or anti-clockwise, (x,y) becomes (y,-x) .
- Then matrix of the rotation 90° is
[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex]
We have the point U (-4, 7) and its image is
U' =[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}-4\\7\end{array}\right][/tex]
U' = [tex]\left[\begin{array}{ccc}-7\\-4\end{array}\right][/tex]
and, point V is (5, 4) and its image is
V' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\4\end{array}\right][/tex]
V' = [tex]\left[\begin{array}{ccc}-4\\5\end{array}\right][/tex]
and, point W is (5, -5) and its image is
W' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\-5\end{array}\right][/tex]
W' = [tex]\left[\begin{array}{ccc}5\\5\end{array}\right][/tex]
So, The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)

HELPPP
Answers
Answer:
If he kept taking notes at the same pace, he would have 16 pages of notes in his notebook.
Step-by-step explanation:
By dividing the number of pages of notes taken by the time spent taking them, you can find his rate of note-taking, which is 4 pages an hour. By adding another hour of notes, he should have 16 pages of notes. But if this question is asking for 4 more hours, the answer would be 28 pages.

The money Mr. Jarod earns, m, varies directly with the number of haircuts he gives, h. He earns $15 for five haircuts. Which equation represents his earnings for the job?
Answers
Answer:
m/h = k
Step-by-step explanation:
Money earned = m
Number of haircuts = h
m α h
m = kh
k is the constant of proportionality
Amount earned for 5 hair cuts = 15
n = 5 ; m = 15
Earning for the job = k
From m = kh
Divide both sides by h
m / h = kh/h
m/h = k
15/5 = 3
Earning for the job = $3

Write an exponential equation that represents the given situation. You invest $1000 and it increases 12% each year. Can you teach me it because i need to show my work, thank you
Answers
Answer:
FV= 1,000*(1.12^n)
Step-by-step explanation:
Giving the following information:
Initial investment= $1,000
Increase rate= 12% = 0.12
We need to formulate an exponential equation to show the value in n years.
To calculate the Future Value, we need to use the following formula:
FV= PV*(1+i)^n
Being:
FV= Future Value
PV= Initial Investment
i= increase rate
n= number of periods
FV= 1,000*(1.12^n)
For example, for one year:
FV= 1,000*(1.12^1)
FV= $1,120
For 3 years:
FV= 1,000*(1.12^3)
FV= $1,404.93

3+3=6
Step-by-step explanation:
. To get 24 multiply 7 with 3 and than add 3 so you can et your answer.
. To get 7 because 7 is a prime number it is a multiple of its own so we can get 7 by simply mutiplying it with 1 or adding it with 0
. 3 is also a prime number so we can get it by multiplying it with 1 or adding it with 0.

On Tuesday, Lisa spent $35.78 at the
grocery store. Later in the week, she
returned. At the end of the week, she
had spent $96.52 at the grocery
store. How much did Lisa spend on
her second trip?
Answers
Answer:
$60.74 on the second trip.
Step-by-step explanation:
Well we know that she spent $35.78 on the first trip.
We DON’T know how much she spent for the second trip so lets put it as “x” for unknown.
We know she spent a TOTAL of $96.52 for those two trips combined.
So we can make a simple equation
35.78+x=96.52
Now solve the equation.
Subtract 35.78 on both sides to isolate the X
35.78-35.78=0
96.52-35.78= 60.74
So if you plug everything in
0+x=60.74
0 is nothing so we can get rid of that
x=60.74
