please answer it asap. thanks in advance:)​

Answers

Answer:

He paid 5,000 for the old home, which was the original price of it.

And he paid 15,000 for the new home.

Step-by-step explanation

Twice the selling price of his old one, the selling price was 7,000

7,000 * 2 = 14000.

14000 + 1000 = 15000.

15,000 is three times more than he originally paid for his old home.

n Purchased a new one for 1,000 more than twice the selling price.

Based on △GHI below, which of the following inequalities is true?

Answers

Answer:

C. [tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]

Step-by-step explanation:

In a triangle, the longest side is opposite to the largest measure of angle. The medium side is opposite to the medium angle, while the shortest side is opposite to the smallest angle.

In ∆GHI,

✍️m<G = 95°, it is opposite to [tex] \overline{HI} [/tex]

<G is the largest angle, therefore, [tex] \overline{HI} [/tex] is the longest side.

✍️m<I = 180 - (95 + 38) = 47°.

<I is opposite to [tex] \overline{GH} [/tex]

<I is the medium angle, therefore, [tex] \overline{GH} [/tex] is the medium side.

✍️m<H = 38°, it is opposite to [tex] \overline{GI} [/tex]

<h is the smallest angle, therefore, [tex] \overline{GI} [/tex] is the shortest side.

✅This means:

[tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]

Step-by-step explanation:

A mixture of purple paint contains 8 teaspoons of red paint and 12 teaspoons of blue paint. To make the same shade of purple paint using 36 teaspoons of blue paint, how much red paint would you need?

Answers

Answer:

24 teaspoons of red paint would be needed.

Step-by-step explanation:

Given that the initial mixture contains 8 teaspoons of red paint and 12 teaspoons of blue paint, this mixture contains a total of 20 units of paint, of which 8 are red, that is, 8 out of 20. Therefore, the proportion of red paint is 40%, while the proportion of blue paint is 60% remaining.

Therefore, in the case of making the same mixture (with the same proportion) using 36 teaspoons of blue paint, the necessary amount of red paint is determined through the following calculation:

60 = 36

40 = X

((40 x 36) / 60) = X

1,440 = 60 = X

24 = X

Thus, 24 teaspoons of red paint would be needed.

first, i’d put the fraction into a decimal, then distribute, for example the fraction would be multiplied by y and 3 separately. then equal that to 40. it should now be a simple equation

Answer:

y = 69

Step-by-step explanation:

start with the distributive property:

5/9 * y and 5/9 * 3

and now you have: 5/9y + 15/9 = 40

and we have to isolate y so subtract 15/9 from both sides:

5/9y + 15/9 = 40

        - 15/9     -15/9

and now you have 5/9y = 345/9

and now divide both sides by 5/9 so: 5/9y divided by 5/9 = y

and 345/9 divided by 5/9 = 345/5 and lets simplify....

y= 69

40 m
130 m

Answers

Answer:

1 hour 29 minutes and 29 seconds

Step-by-step explanation:

We need to find the circumference of the two semicircles of the track (which forms a full circle of radius 40m):

pi×40×2 = 80pi

The total length of the track to be travelled would be:

(80pi+130+130) × 42 = (80pi+260) ×42

                       = 21 476m (Rounded to 5 s.f.)

80m/20s

1s = 80÷20

   = 4m

For every 1 second, Kat travels 4m.

Total Time taken:

21 476÷4 = 5369 seconds

First find slope: (y2-y1)/(x2-x1)
The points: (-3,-1), (6,-7)
(-7+1)/(6+3) = -6/9 = -2/3
Use equation: y = mx + b
y = -2/3x + b
Plot in any point
-1 = -2/3(-3) + b
-1 = 2 + b, b = -3
Final equation in slope intercept form:
Y = -2/3x -3

Answer:

y = -[tex]\frac{2}{3}[/tex] x - 3

Step-by-step explanation:

The general form of the equation of the line (linear equation) is:

y = ax + b

The line passes through (-3, -1) and (6, -7), i.e:

(1) (x=-3, y=-1) is a point that verifies the equation of the line, and

(2) (x=6, y=-7) also verifies the equation.

So we can put up a system of 2 equations to obtain a and b:

y = ax + b

(1) -1 = a (-3) + b

(2) -7 = a (6) + b

______________

substracting (1) - (2) we can obtain a:

-1 - (-7) = a (-3-6) ⇒ 6 = -9 a  a = -2/3

by replacing a in (1) we can obtain b:

-1 = -2/3 (-3) + b ⇒ -1 -2 = b b = -3

so, the equation is:  y = ax + b ⇒ y = -2/3 x - 3

Verification: (2) giving x= 6, let's see if y=-7 is obtained:

y = -2/3 6 - 3 ⇒  y = -4 - 3 = 7 ⇒ RIGHT!

Answer:

m<B = 62°

Step-by-step explanation:

Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:

m<B = m<U

m<B = (3y + 2)°

m<U = (4y - 18)°

Thus,

3y + 2 = 4y - 18

Collect like terms

18 + 2 = 4y - 3y

20 = y

y = 20

m<B = (3y + 2)°

Plug in the value of x

m<B = 3(20) + 2

m<B = 60 + 2

m<B = 62°

While acknowledging that there are greater employment opportunities for Latin American women in cities than in the countryside, social science theorists have continued to argue that urban migration has unequivocally hurt women's status. However, the effects of migration are more complex than these theorists presume. For example, effects can vary depending on women's financial condition and social class. Brazilian women in the lowest socioeconomic class have relatively greater job opportunities and job security in cities than do men of the same class, although there is no compelling evidence that for these women the move to the city is a move out of poverty. Thus, these women may improve their status in relation to men but at the same time may experience no improvement in their economic standing.In addition, working outside the home, which is more common in urban than in rural areas, helps women in the lowest socioeconomic class make contacts to extend exchange networks-the flow of gifts, loans, or child care from those who currently have access to resources to those who do not.Moreover, poor women working in urban areas actively seek to cultivate long-term employer-employee relations.When an emergency arises that requires greater resources than an exchange network can provide, these women often appeal for and receive aid from their wealthy employers.However, the structure of many poor womens work-often a labor force of one in an employers home-makes it difficult for them to organize to improve their economic conditions in general.Not surprisingly, then, Latin American women in the lowest socioeconomic class differ in their opinions about the effects of urban migration on their lives.Some find urban living, with access to electricity and running water, an improvement and would never return to the countryside.Others, disliking the overcrowding and crime, would return to the countryside if there were work opportunities for them there.Thus, urban life has had both negative and positive impacts on womens lives.In general, urban migration has not provided economic prosperity or upward mobility for women in the lowest socioeconomic class, despite their intelligent and energetic utilization of the resources available to them.In the first paragraph, the author refers to the experiences of Brazilian women most probably in order toA. support an earlier assertion made by social science theorists about the effects of urban migrationB. provide an example of one area in which urban migration has failed to improve Latin American womens livesC. substantiate the claim that the effects of urban migration cannot be easily characterizedD. illustrate the effect that urban migration has had on the economic status of Latin American womenE. compare the effect that urban migration has had on the economic status of Latin American women with its effect on the economic status of Latin American men Consider this function. f(x)=2x-2 Which graph represents the inverse of function f? 2.What is the area of a triangle whose vertices are J(-2,1), K(4,3), and L(-2,-5) ?(7 points)a.
