Step-by-step explanation:

Major production and export of cotton and silk yarn ensured Japan achieved an industrial revolution in light industry in the late nineteeth century.

Answer: Great Britain came to Japan and ”forced” it to open its borders for trade and to not be as secluded. the japanese realized how behind they were when it came to technological advancement and that they needed to catch up. So, they began to trade and colonize other countries in order to get proper resources for their industrialization and modernization. They became imperialists in order to accomplish their fast-paced effort of being advanced one again. They were isolated for years before Britain forced themselves in.

Answer:

$1719.55, 61.4%

Step-by-step explanation:

Original price of stove:  $2,800

Value of stove after 1 year:  (1 - 0.15)($2,800), or 0.85($2,800) = $2,380

Value of stove after 2 years:  0.85($2,380) = $1719.55

Find the ratio of this last result to the original price and convert that to a  percentage:

$1,719.55

-------------- = 0.614, or approximately 61.4%

Step-by-step explanation:

So the best thing is to com eup with an equation. I came up with:

150 + 27 - 96 - 31

Deposit means to put money into, so that's why we're adding 27.

And then the checks mean that they are going to be taken out of, so that's why we're subtracting 96 and 31. All that's left to do now is solve.

150 + 27 = 177 - 96 = 81 - 31 = 50

Answer: x = 20

because 2 triangles are similar

=> [tex]\frac{2x-4}{24}=\frac{42}{x+8}[/tex]

⇔ (2x - 4)(x + 8) = 24.42

⇔ 2x² + 12x - 32 = 1008

⇔ 2x² + 12x - 1040 = 0

⇔ 2(x - 20)(x + 26) = 0

because x > 0

=> x = 20

Answer: D) On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (1, negative 1).

On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (1, negative 1). Everything to the right of the line is shaded.

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

A manufacturing machine has two processes. One of them is repeated 4 times and the second only once. The entire cycle can take no longer than 3 minutes.

Let t be the time of the first process in minutes

s be the time of the second process in minutes

we know that the time of the first process multiplied by 4 (because is repeated 4 times) plus the time of the second process multiplied by 1 (because is repeated only once) must be less than or equal to 3 minutes

So, The inequality that represents this situation is

[tex]4t + s\leq 3[/tex]

The y-intercept of the solid line is the point (0,3)

The x-intercept of the solid line is the point (0.75,0)

The slope of the solid line is negative m=-4

Answer:

-2y = 4 - x

2y = x - 4

y = 1/2x - 2

1/2 is the slope of both lines.

y = mx + b

Substitute the given point and the common slope

2 = 1/2 x 2 + b

2 = 1 + b

b = 1

y = 1/2x + 1

The equation of the line that passes through the point

(2, 2) and is parallel to the line x - 2y = 4 is y = 1/2x + 1 or 2y = x + 2.

hope this helps u

plz give me the brainliest i really need it

Answer:

x - 2y = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x - 2y = 4 ( subtract x from both sides )

- 2y = - x + 4 ( divide all terms by - 2 )

y = [tex]\frac{1}{2}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

Parallel lines have equal slopes, thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 2) into the partial equation

2 = 1 + c ⇒ c = 2 - 1 = 1

y = [tex]\frac{1}{2}[/tex] x + 1 ← equation in slope- intercept form

Multiply through by 2

2y = x + 2 ( subtract 2y from both sides )

0 = x - 2y + 2 ( subtract 2 from both sides )

- 2 = x - 2y, that is

x - 2y = - 2 ← equation in standard form

Answer:

the answer would be 5 units for x

Step-by-step explanation:

you would take the x and put it over 10 and then take 10 over 4x and then you would have to cross multiply which would give you 4x^2 =100 and then you would divide 100 by 4 which would give you 24 and then you need to take the square root of 25 which is 5

Answer:

A

Step-by-step explanation:

Given

[tex]\frac{5}{6}[/tex] x - 4 = - 2 ( add 4 to both sides )

[tex]\frac{5}{6}[/tex] x = 2 ( multiply both sides by 6 to clear the fraction )

5x = 12 ( divide both sides by 5 )

x = [tex]\frac{12}{5}[/tex] = 2 [tex]\frac{2}{5}[/tex] → A

Answer:

The 38th term of 459,450,441,.. will be:

[tex]a_{13}=351[/tex]

Step-by-step explanation:

Given the sequence

[tex]459,450,441,..[/tex]

An arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]450-459=-9,\:\quad \:441-450=-9[/tex]

so

[tex]d=-9[/tex]

The first element of the sequence is

[tex]a_1=459[/tex]

so the nth term will be

[tex]a_n=-9\left(n-1\right)+459[/tex]

[tex]a_n=-9n+468[/tex]

Putting n=38 to find the 38th term

[tex]a_n=-9n+468[/tex]

[tex]a_{13}=-9\left(13\right)+468[/tex]

[tex]a_{13}=-117+468[/tex]

[tex]a_{13}=351[/tex]

Therefore, the 38th term of 459,450,441,.. will be:

[tex]a_{13}=351[/tex]

Answer:

There are 3 zeros, which are:

[tex]x=7,\:x=-\sqrt{2},\:x=\sqrt{2}[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)\:=\:x^3\:-\:7x^2\:-\:2x\:+\:14[/tex]

To get the zeros of [tex]f(x)[/tex], set [tex]y[/tex] or [tex]f(x) =0[/tex]

so

[tex]0=x^3-7x^2-2x+14[/tex]

as

[tex]x^3\:-\:7x^2\:-\:2x\:+\:14=\left(x-7\right)\left(x+\sqrt{2}\right)\left(x-\sqrt{2}\right)[/tex]

so

[tex]\left(x-7\right)\left(x+\sqrt{2}\right)\left(x-\sqrt{2}\right)=0[/tex]

Using the zero factor principle:

[tex]\mathrm{ \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

so

[tex]x-7=0\quad \mathrm{or}\quad \:x+\sqrt{2}=0\quad \mathrm{or}\quad \:x-\sqrt{2}=0[/tex]

solving

[tex]x-7=0[/tex]

[tex]x+\sqrt{2}=0[/tex]

[tex]x-\sqrt{2}=0[/tex]

Therefore, there are 3 zeros, which are:

[tex]x=7,\:x=-\sqrt{2},\:x=\sqrt{2}[/tex]

Answer:

36 degrees

Step-by-step explanation:

180 - 58 = 122 degrees

122 - 90 = 32 degrees

32 + 4 = 36 degrees

Answer:

s = 36

Step-by-step explanation:

These lines is 180° in total and the one that is a right triangle has 90° and there is 58° on one so, 180 - 90 - 58 = 32.

32° = s - 4°

32 + 4 = s

36° = s°

Answer:

$40.00

Step-by-step explanation:

the total is 200 so then u subtract the $40 from the coupon which will leave u with 160. Since there is 4 people 160/4 equals 40. Therefore your answer is each person pays $40.00

Answer:

40

Step-by-step explanation:

First subtract the 40 coupon from the equation since it says they use it before paying. Since they all pay the same amount, use x in this case, simply divide 160 by 4, which is 40 for each person. And to double check the answer, multiply 40 by 4, to make sure each person pays the same, then add the 40 dollar coupon, and the answer should be $200. Or, you can think of it as 40x+40(Coupon)=200. Or 200-40=40x.
