For which mapped relation is the domain
{1,2,3}{1,2,3}?

Answer:

A tourist receives 2376 ec currency in exchange for us 1200.

Step-by-step explanation:

This can be calculated as follows:

Tax rate = 1%

Amount of us currency = 1200

Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400

Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24

Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376

Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.

Therefore, a tourist receives 2376 ec currency in exchange for us 1200.

Step-by-step explanation:

A) distribute: 12x +16 = 0; 12x/12 = -16/12

x = -4/3

B) distribute: 420x +180 = 0; 420x/420 = -180/420

x = -3/7

Answer:

x=12

Step-by-step explanation:

(2x-4)/5=4

We move all terms to the left:

(2x-4)/5-(4)=0

We multiply all the terms by the denominator

(2x-4)-4*5=0

We add all the numbers together, and all the variables

(2x-4)-20=0

We get rid of parentheses

2x-4-20=0

We add all the numbers together, and all the variables

2x-24=0

We move all terms containing x to the left, all other terms to the right

2x=24

x=24/2

x=12

Answer:

x = 12

Step-by-step explanation:

Given

[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )

2x - 4 = 20 ( add 4 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Correlation coefficient is a quantitative measure used to determine the statistical relationships between two or more random variables or observed data values. Here -1.0 states the perfect negative correlation, while 1.0 states the perfect positive correlation. ...

Answer:

The equation in the slope-intercept form will be:

[tex]y=-\frac{49}{39}x+0[/tex]

Step-by-step explanation:

Given the points

Finding the slope between the points using the formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-39,\:49\right),\:\left(x_2,\:y_2\right)=\left(0,\:0\right)[/tex]

[tex]m=\frac{0-49}{0-\left(-39\right)}[/tex]

[tex]m=-\frac{49}{39}[/tex]

We know that the point-slope of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting [tex]m=-\frac{49}{39}[/tex] and (-39,49)  in the equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]

Now writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]

[tex]y-49=\frac{-49}{39}\left(x+39\right)[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]

[tex]y-49=-\frac{49}{39}\left(x+39\right)[/tex]

[tex]\mathrm{Add\:}49\mathrm{\:to\:both\:sides}[/tex]

[tex]y-49+49=-\frac{49}{39}\left(x+39\right)+49[/tex]

[tex]y=-\frac{49}{39}x+0[/tex]              ∵ [tex]y=mx+b[/tex]

Where

[tex]m=-\frac{49}{39}[/tex] and the y-intercept i.e. [tex]b=0[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=-\frac{49}{39}x+0[/tex]

Answer:

The value of x = 5

Step-by-step explanation:

Length of the pool = 20 feet

Width of the pool = (20 minus x) feet

Area of the pool = 300 square feet

Area of a rectangular pool = length × width

300 = 20 (20 - x)

300 = 400 - 20x

Subtract 400 from both sides

300 - 400 = 400 - 20x - 400

- 100 = - 20x

Divide both sides by -20

x = -100/-20

= 5

x = 5

The value of x = 5

Answer:

noentiendo. que preguntas?

Step-by-step explanation:

Answer:

1) 199

2) 899

Step-by-step explanation:

1)

The 2-digit number is the number formed from unit-digit and ten-digit

∵ The greatest digit is 9

→ To form the greatest 2-digit number use 9 as ten-digit and unit-digit

∴ The greatest 2-digit number is 99

The 3-digit number is the number formed from unit-digit, ten-digit, and hundred-digit

∵ The smallest digit is 0

→ To form the smallest 3-digit number use 0 as ten-digit and unit-digit,

   we can not use 0 for the hundred-digit so use 1 as hundred-digit  

∴ The smallest 3-digit number is 100

∵ The sum of them = 99 + 100

∴ Their sum is 199

2)

→ To form the greatest 3-digit number use 9 as hundred-digit, ten-digit,

   and unit-digit

∴ The greatest 3-digit number is 999

∵ The smallest 3-digit number is 100

∵ The difference between them = 999 - 100

∴ The difference between them = 899

Answer:

C

Step-by-step explanation:

a number is divisible by 5 if it ends in 5 or 0

since we know that, we know that A is not correct.

a number is divisible by 10 if it ends in 0

from this, we can see that C is the correct answer because it ends in a 0

answer=c

hope this helps!

Answer: 12/11

Step-by-step explanation:

(6/11) / (3/6)

(6/11) * (6/3) = 36/33 = 12/11

Answer:

12/11

Step-by-step explanation:

6/11 / 3/6

Simplify

6/11 / 1/2

Preform division, remember, dividing a number by a fraction is the same as multiplying that number by the reciprocal of that fraction

6/11 * 2/1

12/11

Answer:

b. AD II DC

math is annoying, a lot of the stuff they teach we don't use in the real world lol

If anything, AB DC seems like it would be right because AD BC doesnt line up with angles real well. Im not entirely sure; educated guessing.

Answer:

The answer is in the explaination

Step-by-step explanation:

A + B = 180 degrees

14x - 72 = 180

14x = 108

x = 8

A = 5 times 8 plus 20

A = 60

Answer:

110 degrees.

Step-by-step explanation:

Angle A + Angle B = 180 degrees.

Therefore, 5x+20+9x-92=180

When you solve you get 14x=252 or x=18

When you plug that into A you get 5(18)+20=110

Therefore, A=110 degrees

Answer:

Solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]

Step-by-step explanation:

We need to solve:

[tex]6^2-(1.1+7.4)+1.5[/tex]

First solving brackets

[tex]=6^2-(8.5)+1.5\\=6^2-8.5+1.5\\[/tex]

Now solving 6^2

[tex]=36-8.5+1.5\\[/tex]

Now subtracting 8.5 from 36

[tex]=27.5+1.5[/tex]

Now adding the above values

[tex]=29[/tex]

So, solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]
