Using simple division we know that 86 people or citizens dies each day in 2015.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

Division in mathematics is the process of dividing an amount into equal parts.

For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.

So, we know that:

31,500 people died in 2015.

We also know that 2015 had 365 days.

Then, people died easily day would be:

= 31,500/365

= 86.30

Rounding off: 86 people

Therefore, using simple division we know that 86 people or citizens dies each day in 2015.

Answer:

12 multiple choice and 8 True/False

Step-by-step explanation:

To do this we set up a system of equations. Let x represent the True/Fale questions and y represent the multiple-choice questions. Here is a system we can use:

x + y = 20

2x + 7y = 100

We can solve this by using elimination. To do this we multiply one equation by a number, and add them together. If we multiply the first equation by -2, the "x"s will, when added together, cancel out so we can solve for y.

-2(x + y = 20)

-2x - 2y = -40

Now add them together

5y = 60

Solve for y.

y = 12

This means there are 12 multiple choice questions. 20 - 12 is 8 True/False questions.

Hope this helps and have a great day! :D

Answer:

8 True/False and 12 Multiple Choice

Step-by-step explanation:

x+y=20  ...1

2x+7y=100   ...2

Now you can multiply 2 on 1

2x+2y=40

2x+7y=100

Subtract:

-5y=-60

Divide -5 on both sides:

y=12

Substitute y with 12

x+12=20

Subtract 12 on both sides:

x=8

So there are 8 True/False and 12 Multiple Choice

We get the values of RS and RT as 6 and 17 respectively after solving the equations.

We are given the equations:

RS = 2x - 8

ST = 11

RT = x + 10

Now, we know that:

RS + ST = RT.

Substituting the values, we get that:

2 x - 8 + 11 = x + 10

2 x + 3 = x + 10

2 x - x = 10 - 3

x = 7

Now substituting it to find RS and RT:

RS = 2 x - 8

RS = 2 ( 7 ) - 8

RS = 14 - 8

RS = 6

RT = x + 10

RT = 7 + 10

RT = 17

Therefore, we get the values of RS and RT as 6 and 17 respectively after solving the equations.

Answer:

x = 67

Step-by-step explanation:

2x - 17 + 63 = 180 {Linear pair}

     2x + 46  = 180    

             2x = 180 - 46

             2x = 134

               x = 134/2

              x = 67

\(\color{plum}\bold{x \tt \: = 67}\)

∠63° and ∠(2x-17)° are a linear pair, so their sum will be equal to 180°.

Which means :

\( = 63 + 2x - 17 = 180\)

\( = 63 + 2x = 180 + 17\)

\( = 63 + 2x = 197\)

\( = 2x = 197 - 63\)

\( = 2x = 134\)

\( = x = 67\)

Let us place 67 in the place of x and see if the substitution is equivalent to 180° :

\( = 63 + 2 \times 67 - 17 = 180\)

\( = 63 + 134 - 17 = 180\)

\( = 63 + 117 = 180\)

\( = 180 = 180\)

Thus, the value of x we found out is correct.

Therefore, x = 67

Answer:

27.78%

Step-by-step explanation:

To calculate the percentage of the total spending that is on rent, we need to divide the amount spent on rent by the total amount spent, and then multiply by 100 to get the percentage.

Total spending = food + rent + other + fun

Total spending = $400 + $500 + $600 + $300

Total spending = $1800

So, the percentage of the total spending that is on rent is:

($500 / $1800) x 100% = 27.78%

Therefore, approximately 27.78% of the total spending is on rent.

Answer:

  5.1% increase

Step-by-step explanation:

You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.

The percentage change is given by the formula ...

  ((new price)/(old price) -1) × 100%

The price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.

  old price per load = $16.99/52 ≈ $0.32673

  new price per load = $16.49/48 ≈ $0.34354

Then the percentage change is ...

  (0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%

The price per load has increased by about 5.1%.

Answer:

\(r \geqslant - 16\)

Step-by-step explanation:

\( \frac{ - 10 + r}{2} \geqslant - 13\)

multiply both sides by 2:

\( - 10 + r \geqslant - 26\)

add 10 on both sides:

\(r \geqslant - 16\)

Answer:

\(r \ge -16\)

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

\(\frac{-10+r}{2} \ge -13\)

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

\(\frac{-10+r}{2} *2 \ge -13 *2\)

\(-10+r \ge -26\)

Add 10 to both sides, and simplify

\((-10+r)+10 \ge (-26)+10\)

\(r \ge -16\)

The equation, x^2 = 25 has two solutions as the values of x, which are either x = 5 or x = - 5.

x^2 = 25 [Given]

subtracting 25 from both sides, the equation becomes:

x^2 - 25 = 0

Applying the difference of two squares on the right-hand side, R.H.S. of the equation, it will become:

x^2 - 5^2 = 0

∴ (x - 5)(x+5) = 0

Thus, either: x - 5 = 0 or x + 5 = 0

Hence, x = 5 or x = - 5

Thus, the solutions (or roots) of x are 5 and -5, making them two solutions.

Hence, from the above, the equation, x^2 = 25, has two (2) solutions because the roots or solutions of the given quadratic equations obtained were 5 and  - 5.

Given statement solution is :- Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

To analyze the steady matrix for this situation, let's consider the two groups of customers: those who turn in tickets and those who do not turn in tickets.

Let's denote the proportion of customers who turn in tickets as X and the proportion of customers who do not turn in tickets as Y.

According to the given information:

40% of the customers who turn in tickets do not turn in tickets the following week. This means that 60% of the customers who turn in tickets will turn in tickets again the following week.

30% of the customers who do not turn in tickets will turn in tickets the following week. This means that 70% of the customers who do not turn in tickets will continue not turning in tickets the following week.

Based on these percentages, we can construct the steady matrix:

Copy code

     |  Customers turning in tickets (X) | Customers not turning in tickets (Y) |

----------|----------------------------------|--------------------------------------|

Next week 0.6 0.3

This week 0.4 0.7

Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The value 0.4 in the bottom left cell represents the proportion of customers who do not turn in tickets this week but will turn in tickets next week.

The value 0.7 in the bottom right cell represents the proportion of customers who do not turn in tickets this week and will continue not turning in tickets next week.

These values describe the transition probabilities between the two customer groups. For example, if there are 100 customers in total, 60 of them will turn in tickets next week, and 40 of them will not. Similarly, 30 customers who turn in tickets this week will not do so next week, while 70 customers who do not turn in tickets this week will continue to not turn them in next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

Habían inicialmente 84 vacas. Murieron 36 vacas. 24 vacas fueron vendidas.

Step-by-step explanation:

Sea \(x\) la cantidad inicial de vacas. De acuerdo con el enunciado, murieron tres séptimos de la cantidad inicial y la mitad de ese remanente fue vendida, quedando 24 vacas. Matemáticamente, tenemos las siguientes operaciones:

Cantidad inicial de vacas

\(x = \frac{24}{\left(1-\frac{3}{7} \right)\cdot \left(1-\frac{1}{2} \right)}\)

\(x = 84\)

Habían inicialmente 84 vacas.

Cantidad de vacas muertas

\(y = \frac{3}{7}\cdot x\)

\(y = 36\)

Murieron 36 vacas.

Cantidad de vacas vendidas

\(z = \left(1-\frac{3}{7} \right)\cdot \frac{1}{2}\cdot x\)

\(z = 24\)

Choice C

Step-by-step explanation:

Notice that the equation y = 0.5 x + 5

is a linear equation so the points that are solutions of it must reside on a line. Option A does not show aligned points, so it cannot be a possible answer.

Option B: we look into the given points and notice that just the first one (1, 0) is NOT a solution to the equation because:

y = 0.5 (1) + 5 = 5.5 and not "0"

Option C: This is the correct answer, since all those points satisfy the equation

Point (2, 6)  -->  y = 0.5 (2) + 5 = 1 + 5 = 6

Point (4, 7)  -->   y = 0.5 (4) + 5 = 2 + 5 = 7

Point (6, 8) -->   y = 0.5 (6) + 5 = 3 + 5 = 8
