Step-by-step explanation:

x = number of children

y = number of adults

x + y = 364

x = 364 - y

1.75x + 2.25y = 707.5

using the first equation in the second :

1.75(364 - y) + 2.25y = 707.5

637 - 1.75y + 2.25y = 707.5

637 + 0.5y = 707.5

0.5y = 70.5

y = 70.5/0.5 = 141

x = 364 - y = 364 - 141 = 223

there were 223 children at the public pool.

225 pounds of the Earl Grey tea and 375 pounds of Orange Pekoe tea are​ required to get 600 pounds of a new blend costing $3.50

An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.

Let x represent the amount of Earl Grey tea and y represent the amount of Orange Pekoe tea.

Earl Grey tea sells for $6 per pound while Orange Pekoe tea sells for $2 per pound. Both teas were mixed to get 600 pounds of a new blend selling at $3.50. Hence:

x + y = 600    (1)

Also:

6x + 2y = 3.5(600)    (2)

The pendulum will swing at the velocity of 3.06 m/s at the bottom of the swing.

Velocity is the rate of change of position of an object, usually measured in meters per second (m/s). It is a vector quantity, which means it has both magnitude and direction. Velocity is an essential notion in physics since it is used to describe motion and is one of the fundamental principles of classical mechanics. It is connected to other notions such as acceleration, momentum, and force. Velocity is a measure of how rapidly an item moves in a specific direction, and it is computed by dividing the distance travelled by the time it takes for the object to traverse that distance.

The speed of the pendulum at the bottom of its swing can be calculated using the formula:

v = √(2gh)

where v = velocity, g = gravitational acceleration (9.8m/s2), h = height (1.22m)

Therefore, the speed of the pendulum at the bottom of its swing is:

v = √(2*9.8*1.22)

v = 3.06 m/s

Answer: For each hour worked, the number of tickets sold increases by 12.

Step-by-step explanation:

The constant of proportionality for the table can be found by dividing the value of y by the value of x for one of the data points. For example, when x = 2, y = 24, so the constant of proportionality k can be found as follows:

k = y/x = 24/2 = 12

So, the equation relating the number of hours worked, x, to the number of tickets sold, y, can be written as y = kx, where k is the constant of proportionality, which we found to be 12.

Thus, the equation relating the number of hours worked, x, to the number of tickets sold, y, can be written as:

y = 12x

This equation states that for each hour worked, the number of tickets sold increases by 12.

The discount is $278.59 and the proceeds for the following simple discount note,  using 360 days for a year is $9421.41

Discount refers to a reduction in the price of an item or service. It can be expressed as a percentage or an absolute value, and it is usually calculated as a difference between the original price and the reduced price. In finance, discount is often used to refer to the reduction in the face value of a financial instrument, such as a bond or a bill, before it matures. The amount of the discount is usually based on the interest rate and the time to maturity. The term "discount" is also used in various other contexts, such as in retail sales, where items are sold at a lower price than their regular price to encourage customers to buy.

(a) The discount is calculated by multiplying the face value of the note by the discount rate and then dividing by the number of days in a year (360).

Discount = $9700 * 9.5% * 135/360

Discount = $9700 * 0.095 * 3/10

Discount = $9700 * 0.285/10

Discount = $278.59

(b) The proceeds are calculated by subtracting the discount from the face value of the note.

Proceeds = Face Value - Discount

Proceeds = $9700 - $278.59

Proceeds = $9421.41

The equation that represents the given graph is: D. y = 2/5x - 3.

The slope-intercept form of the equation of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept.

here, we have,

To find the equation of a line that passes through two points (x1, y1) and (x2, y2), we can use the following steps:

Find the slope (m) using the formula

m = (y2 - y1) / (x2 - x1).

Plug in the slope and one of the points into the equation

y = mx + b to find b.

So, for the line that passes through the points (0, -3) and (5, -1),

the slope is (-1 - (-3)) / (5 - 0)

                 = 2/5,

and the y-intercept can be found by plugging in the slope and the point (0, -3) into the equation y = mx + b:

-3 = (2/5) * 0 + b

-3 = b

Therefore, the equation of the line that passes through (0, -3) and (5, -1) is:  y = (2/5)x - 3

Answer:

The "one number" is equal to 4 and "another number" is equal to 6.

Step-by-step explanation:

1. We can write an equation for "one number": X = 2n - 8 (X is one number and another number is N)

2. Since their sums are 10 we can write it was X + N

3. Plug in the value of X to get: 2n - 8 + N = 10

4. Put 8 to the other side to get + 8 --> 2n + N = 10 + 8

5. Now you form the equation 3n = 18

6. N = 18 / 3 which is 6

7. To get X you do 10 - 6 which is equal to 4

8. To make sure the answer is correct plug in the values into the equation: 4 = 2(6) - 8 which simplifies to 4 = 12 - 8

Therefore, one number is equal to 4 and another number is equal to 6

b21 b22 b23 ... b2m

...

bn1 bn2 bn3 ... bnm

you have to consider that this is only possible, when A has m rows and n columns, and B has n rows and m columns.

because the rows of A are multiplied by the columns of B.

the resulting matrix C is a square matrix and looks like

c11 c12 c13 ... c1m

xy = 5/9                  ...1

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Answer:

a. In a class of 58 students, 35 students offer Biology, 28 students offer Economics and 15 students offer Physics.

Using the Principle of Inclusion-Exclusion, we can calculate the number of students who offer all three subjects as follows:

The total number of students who offer at least one subject is 35 + 28 + 15 = 78

The number of students who offer Biology and Economics is 12

The number of students who offer Biology and Physics is 7

The number of students who offer Economics and Physics is 5

So the number of students who offer all three subjects is given by:

35 + 28 + 15 - (12 + 7 + 5) = 58 - 24 = 34

Therefore, 34 students offer all three subjects.

b. A regular polygon with (2m + 1) sides has each interior angle equal to 1440.

Each interior angle of a regular polygon with n sides is given by:

angle = (n-2) * 180 / n

So for a regular polygon with (2m + 1) sides, we have:

1440 = (2m + 1 - 2) * 180 / (2m + 1)

Expanding and simplifying:

1440 = 360m / (2m + 1)

Multiplying both sides by (2m + 1):

1440 * (2m + 1) = 360m

Expanding the left side:

2880 + 1440 = 360m

4320 = 360m

Finally, dividing both sides by 360:

m = 12

Therefore, the value of m is 12.
