There are 20 Canadians and 20 Americans at the conference.

we met the first person may be Canadian or American

Case 1:

If the first person is Canadian

We meet the second person

The second person also maybe Canadian or American

If all the first 20 peoples are Canadian

The next two people should be American

Hence we should meet a minimum of 22 people.

Case 2:

If the first person is American

We meet the second person

The second person also maybe Canadian or American

If all the next 20 peoples are Canadian

Then the 22nd people should be American

Hence we should meet a minimum of 22 people.

Case 3:

If the first person is American

We meet the second person

The second person also maybe Canadian or American

If the second people is also American

Hence we met 2 Americans in two attempts.

We are given the following equation:

we are asked to determine any extraneous solutions. To do that we will determine the values of "x" that solve the equation. First, we will cross multiply the equation:

Now, we can multiply by -1, we get:

Now we use the distributive property on both sides, we get:

Now, we subtract "3x" from both sides:

Now we subtract 24 from both sides:

Therefore, the solution is x = -12. The extraneous solutions are the solutions that are not in the domain of the original function.

In the domain of the original function, we have that the values of:

Would make the denominators equal to zero, and therefore, they are not in the domain. Since the solution is none of these values there are no extraneous solutions.

To simplify the problem above, use PEDMAS theorem.

Thus, we have:

The slope of a line is given by the following formula:

Where (x1, y1) and (x2, y2) are the coordinates of two points where the line passes through. By replacing (2, -9) and (8, -6) into the above equation, we get:

Then, the slope of the given line is 1/2. The equation of a line can be written in slope-intercept form like this:

y = mx + b = (1/2)x + b

We can find the value of b by replacing the coordinates of one of the point where the lie goes through, let's take (2, -9), then we get:

-9 = (1/2)(2) + b

-9 = 1 + b

-9 - 1 = 1 - 1 + b

-10 = b

b = -10

Then, we can rewrite the above equation to get: y = (1/2)x - 10

The amount loaned at 8% interest is $15000

Using the simple interest formula, we find the interest obtained at each rate.

Simple interest, I = PRT where

Now, the interest obtained at 8%,I₁ = P₁R₁T where

Also, the interest obtained at 16%,I₂ = P₂R₂T where

So, the total interest received is I = I₁ + I₂

=  P₁R₁T +  P₂R₂T

= P₁ × 0.08 × 1 +  P₂ × 0.16 × 1

= 0.08P₁ + 0.16P₂

Since the total interest received is $2000,we have that

I = $2000.

So, I = 0.08P₁ + 0.16P₂

0.08P₁ + 0.16P₂ = 2000  (1)

Since the amount loaned by the bank is P = P₁ + P₂ and P = $20000, we have that

P₁ + P₂ = 20000

P₂ = 20000 - P₁   (2)

Substituting equation (2) into (1), we have that

0.08P₁ + 0.16P₂ = 2000  (1)

0.08P₁ + 0.16(20000 - P₁) = 2000  

Expanding the brackets, we have

0.08P₁ + 0.16 × 20000 - 0.16P₁ = 2000  

0.08P₁ + 3200 - 0.16P₁ = 2000  

0.08P₁ - 0.16P₁ = 2000 - 3200

- 0.08P₁ = -1200

P₁  = -1200/-0.08

P₁  = 15000

So, the amount loaned at 8% is $15000

The question seems incomplete, here is the complete question

A bank loaned out ​$20,000​, part of it at the rate of 8 % per year and the rest at 16 % per year. If the interest received in one year totaled ​$2000​, how much was loaned at 8 %

We want to write the following system

As a matrix. To do that, we just take the coefficients and plug them in the same order in a matrix. Our system can be rewritten as:

Now, to solve this, we can use the gaussian elimination. It consists of adding, multiplying, and changing the order of the rows, until we have an identity matrix on the left side.

Let's start by subtracting the second row from the third row, and subtracting 2 times the second row from the first row.

Multiplying the first row by (- 1), we have:

Adding the first row to the third row, we have:

The least precise place value is in the 10's place is 182.5.

Given that, 67.4 +43 +30 + 42.10.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.

Now,

67.4 + 42.10 + 73

= 109.5 + 73

= 182.5

Hence, the least precise place value is in the 10's place is 182.5.

For this problem we know that the sum of 3 consecutive numbers is one hundred five. Let's assume that the 3 numbers is: a, a+1, a+2

And we can set up the following equation:

And we can solve for a like this:

We can subtract 3 in both sides and we got:

And we can divide both sides by 3 and we got:

And we can conclude that the smallest number is 34

The product of the slopes of the perpendicular lines = -1

If the slope of one is m, then the slope of the other is -1/m

The given equation is y = -2x - 1

The form of the equation is y = m x + b, where

m is the slope of the line

So the slope of the given line is m = -2

To find the slope of the perpendicular line reciprocal it and change its sign

The slope of the perpendicular line = 1/2

Substitute it in the form of the equation

y = 1/2 x + b

To find b substitute x and y of the equation by the coordinates of any point on the line

The line passes through point (2, -1), then

x = 2 and y = -1

-1 = 1/2 (2) + b

-1 = 1 + b

Subtract 1 from both sides to find b

-1 - 1 = 1 - 1 + b

-2 = b

The equation of the perpendicular line is

y = 1/2 x - 2

Since the load L varies directly with the product of width and square of the height h, and inveresly as the length l, so

We will use the second rule

Since L is 8740 pounds when w is 5 in., h is 7 in. and l is 144 in.

We need to find L when w is 6 in., h is 9 in. and l is 216 in.

Let us substitute them in the second rule

By using cross multiplication

Divide both sides by 245

Round it to the nearest integer

The load is 11558 pounds

The function is

y=0,7x+80

and they ask you the point (6, )

this means x=6

so we need to replace x=6 on the function and find out the value of y

Y=0,7*6+80

Y=4.2+80=84.2

So the answer is: (6, 84.2)

and this means that 6 years before 1999, the number of households that have at least one microwave is 84.2 million

For C. 2014 is (2014-1999=15) 15 years after 1999

So we replace x=15

Y=15*0,7+80=90.5

So the answer is: 90.5 million households
