8000 is the population of village in 1970.

Given that:

The linear equation of the population, P, of a village t years after it was founded in 1970, is given by

P(t) = 8000 + 600t.

To find:

What is the population in 1970 ?

So, according the question

We have,

The population of a village after t years from 1970 in a form of linear equation is,

 P(t) = 8000 + 600t.

This linear equation was founded in 1970, so t years will be counted after 1970. If we need to find the population of a village in 1971, we can use t = 1971 - 1970, which is one year. But here we have to find the population of a village in 1970, so the value of time is 0.

Now, putting the value of t.

We will be get,

 P(t) = 8000 + 600t.

 P(0) = 8000 + 600 × 0.

 P = 8000

So, the population of a village in 1970 is 8000.

The angels of parallelogram is 162, 18, 162 and 18.

given that A parallelogram has one angle that measures 18° means one angle is 18°

we know that

A special variety of quadrilateral called a parallelogram has two sets of opposite sides that are parallel and equal.

The sum of all the angels of parallelogram is equal to 360°

so, the other means second angle of parallelogram is 18°

Let us assume the 3rd be x.

then the 4th also be x, because the opposite sides are equal.

now sum of all angles is 360°

then x + 18 + x + 18 = 360

2x + 36 = 360

2x = 360 - 36

x = 162.

so the 3rd and 4th angles are 162°.

Hence the angels of parallelogram is 162, 18, 162 and 18.

The measures of angle ACB and angle ABC are 40° and 63° respectively

From the information given, we have that angle DAB is on a straight line

But angle D is 103°

Remember that angles on a straight line sum up to 180°

Then,

103° + Angle A = 180°

Angle A = 180 - 103

Angle A = 77°

It is important to note that sum of angles in a triangle is 180°

angle ACB + angle ABC + angle CAB = 180°

Where;

Substitute into the formula

3x - 14 + 3x + 9 + 77 = 180

collect like terms

3x + 3x = 180 - 72

6x = 108

Make 'x' the subject

x = 108/6

x = 18

But;

Angle ACB = 3x - 14 = 3(18) - 14 = 54 - 14 = 40°

Angle ABC = 3x + 9 = 3(14) + 9 = 54 + 9 = 63°

Thus, the measures of angle ACB and angle ABC are 40° and 63° respectively.

The shifted point G when translated to left 4 units and up 3 units has coordinate ( -8, 6).

Rotation, translation, Reflection, and Dilation are the four types of translation.

Assuming the square boxes of the paper graph are 1 sq unit means each side is 1 unit.

Now by counting we can conclude that before shifting the point has an x coordinate of - 4 units and a y coordinate of 3 units.

∴ The coordinates of the points are (-4, 3).

Now it has been shifted left 4 units and up 3 units, We know going towards left is negative on the x coordinate and going towards up is positive on the y coordinate.

One gallon of pure acid must be added to get a 40% acid solution.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

Given that

3 gallons of a 40% acid solution means you have (20%)×(3) = 0.6 gallons of acid already.

Let x of gallons of pure acid be added to get a 40% acid solution.

⇒ (0.6 +x)/(3+x) = 40%

⇒ (0.6 +x)/(3+x) = 4/10

Cross multiply, we get

⇒ 10(0.6+x) = 4(3+x)

⇒ 6 + 10x = 12 + 4x

⇒ 10x - 4x = 12 - 6

⇒ 6x = 6

⇒ x = 1

Therefore, one gallon of pure acid must be added to get a 40% acid solution.

Given that worker in the United States and a worker in China can each produce 1,000 pairs of jeans per week and A worker in the United States can produce 50 cell phones, and a worker in China can produce 100 cell phones in given time.

US: opportunity cost of jeans = 50/1000= 0.05;

1Jeans = 0.05 cell phones

China: opportunity cost of jeans = 100/1000= 0.1

1 jeans= 0.1cell phones

US: opportunity cost of cell phones= 1000/50= 20

1 cell phone= 20 jeans

China: opportunity cost of cell phones = 1000/100= 10

1 cell phone = 10 jeans

Each country will give equal time for producing each product.

Thus, each firm will produce half of its capacity when they combined there production.

So, pair of jeans US will produce in a week 1000/2 = 500 pair jeans a week

Cell phones US will produce in a week 50/2 = 25 cell phones in a week.

Similarly, pair of jeans china will produce in a week 1000/2 = 500 pair jeans a week

& Cell phones china will produce in a week 100/2 = 50 cell phones in a week.

The total number of jeans produced by the two countries combined is

500+500=1000

The total number of cell phones produced by the two countries combined is 25+50=75.

Hence, The jeans and cell phones produced by US will be 500 and 25 and jeans and cell phones produces by china will be 500 and 50 and the total number of jeans and cell phones is 1000 and 75 when United States and a worker in China can each produce 1,000 pairs of jeans per week.

In this problem we find a polygon generated by four vertices, whose locations are shown in the picture and whose image must be found by using rigid transformation formulas.

Rigid transformations are transformations such that the form of a geometric loci is conserved, dilations are an example of rigid transformation. The general formula of a dilation is described below:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]  

Where:

If we know that O(x, y) = (- 2, 4), k = 2 / 3, T(x, y) = (7, 1), U(x, y) = (4, 4), V(x, y) = (1, 13) and W(x, y) = (- 2, 4), then the coordinates of the polygon are now determined:

T'(x, y) = (- 2, 4) + (2 / 3) · [(7, 1) - (- 2, 4)]

T'(x, y) = (- 2, 4) + (2 / 3) · (9, - 3)

T'(x, y) = (- 2, 4) + (6, - 2)

T'(x, y) = (4, 2)

U'(x, y) = (- 2, 4) + (2 / 3) · [(4, 4) - (- 2, 4)]

U'(x, y) = (- 2, 4) + (2 / 3) · (6, 0)

U'(x, y) = (- 2, 4) + (4, 0)

U'(x, y) = (2, 4)

V'(x, y) = (- 2, 4) + (2 / 3) · [(1, 13) - (- 2, 4)]

V'(x, y) = (- 2, 4) + (2 / 3) · (3, 9)

V'(x, y) = (- 2, 4) + (2, 6)

V'(x, y) = (0, 10)

W'(x, y) = (- 2, 4) + (2 / 3) · [(- 2, 4) - (- 2, 4)]

Answer:

[tex]17[/tex] and [tex]20[/tex].

Step-by-step explanation:

Let [tex]x[/tex] denote the larger one of the two positive integers ([tex]x > 0[/tex].) The smaller integer would be [tex](x - 3)[/tex]. The square of the larger integer would be [tex]x^{2}[/tex].

The sum of the smaller integer and the square of the larger integer is [tex](x^{2} + (x - 3))[/tex]. If this sum is equal to [tex]417[/tex], then:

[tex]x^{2} + x - 3 = 417[/tex].

[tex]x^{2} + x - 420 = 0[/tex].

Solve this quadratic equation for [tex]x[/tex] through factorization. Since [tex]420 = 21 \times 20[/tex]:

[tex]x^{2} + x - (21 \times 20) = 0[/tex].

[tex]x^{2} + 21\, x - 20\, x + (21)\, (-20) = 0[/tex].

[tex](x + 21)\, (x - 20) = 0[/tex].

Thus, either [tex]x = 20[/tex] or [tex]x = (-21)[/tex] by the Factor Theorem. However, since [tex]x > 0[/tex] (the two integers are both positive,) only [tex]x = 20[/tex] is a valid solution.

Hence, the larger one of the two integers would be [tex]20[/tex]. The smaller one of the two integers would be [tex](x - 3) = (20 - 3) = 17[/tex].
