Three consecutive integers whose sum is 360 can be found by using algebraic equations. Let x be the first integer, then the second and third consecutive integers will be x+1 and x+2 respectively. Therefore, the sum of three consecutive integers is the sum of x, x+1, and x+2.

The equation for the sum of three consecutive integers can be written as:

x + (x + 1) + (x + 2) = 360

This can be simplified as:

3x + 3 = 360

Subtracting 3 from both sides gives:

3x = 357

Finally, we can divide both sides by 3 to isolate the value of x:x = 119

Therefore, the three consecutive integers whose sum is 360 are 119, 120, and 121.We can check that the sum of these integers is indeed 360 by adding them up:

119 + 120 + 121 = 360

The three consecutive integers whose sum is 360 are 119, 120, and 121.

Step-by-step explanation:

( 1 ): ANSWER: 85 * ((1050 / 85)^(1/75))^t

To represent the exponential growth of bacteria cells in the dish, we can use the formula:

n = P * (1 + r)^t

where:

n represents the number of cells in the dish after t minutes,

P is the initial number of cells at the start of the experiment,

r is the growth rate per minute,

t is the time in minutes.

In this case, we know that at the start (t = 0), there are 85 cells (P = 85). After 75 minutes (t = 75), there are 1050 cells. We can use these values to find the growth rate (r).

Using the formula, we have:

1050 = 85 * (1 + r)^75

To solve for r, we can rearrange the equation and take the 75th root of both sides:

(1 + r)^75 = 1050 / 85

(1 + r) = (1050 / 85)^(1/75)

Now, we can substitute this value of (1 + r) back into the equation to find the exponential growth equation:

n = 85 * (1 + r)^t

n = 85 * ((1050 / 85)^(1/75))^t

Therefore, the exponential growth equation to represent the number of cells (n) in the dish after t minutes is:

n = 85 * ((1050 / 85)^(1/75))^t

( 2 ): ANSWER: 5.12 P.M.

To predict the time when there will be 10,000 cells in the dish, we can use the exponential growth equation:

n = 85 * ((1050 / 85)^(1/75))^t

We need to solve for t, the time in minutes. Rearranging the equation:

((1050 / 85)^(1/75))^t = 10000 / 85

Taking the logarithm of both sides:

t * log((1050 / 85)^(1/75)) = log(10000 / 85)

Dividing both sides by log((1050 / 85)^(1/75)):

t = log(10000 / 85) / log((1050 / 85)^(1/75))

Using a calculator, we find that t is approximately 311.56 minutes. Since we started at 1:00 P.M., we can add 311.56 minutes to find the predicted time when there will be 10,000 cells in the dish:

1:00 P.M. + 311.56 minutes = 5:12 P.M.

Therefore, based on the given exponential growth equation, it is predicted that there will be approximately 10,000 cells in the dish at around 5:12 P.M., rounded to the nearest minute.

Answer:

x - 11

Step-by-step explanation:

f(x) = -5x - 4

g(x) = 6x - 7

Find f(x) + g(x).

To find the sum of f(x) and g(x), we must substitute f(x) and g(x) with the given equations:

(-5x - 4) + (6x - 7)

To solve, we combine like terms.

-5x + 6x = x

-4 + (-7) = -11

Therefore, we end up with x - 11.

Step-by-step explanation:

y = 4 − 2x? b is the y -intercept. Here, 4 is b and −2 is m. Therefore, the slope is −2.

Neither of the given ordered pairs (2, 3) and (9, -1) is a solution to the equation (1/3)x + 3y = 10.

To determine if the given ordered pairs are solutions to the equation (1/3)x + 3y = 10,

We can substitute the values of x and y into the equation and check if the equation holds true.

Let's evaluate each point:

1) Ordered pair (2, 3):

Substituting x = 2 and y = 3 into the equation:

(1/3)(2) + 3(3) = 10

2/3 + 9 = 10

2/3 + 9 = 30/3

2/3 + 9/1 = 30/3

(2 + 27)/3 = 30/3

29/3 = 30/3

The equation is not satisfied for the point (2, 3) because the left side (29/3) is not equal to the right side (30/3).

Therefore, (2, 3) is not a solution to the equation.

2) Ordered pair (9, -1):

Substituting x = 9 and y = -1 into the equation:

(1/3)(9) + 3(-1) = 10

3 + (-3) = 10

0 = 10

The equation is not satisfied for the point (9, -1) because the left side (0) is not equal to the right side (10). Therefore, (9, -1) is not a solution to the equation.

In conclusion, neither of the given ordered pairs (2, 3) and (9, -1) is a solution to the equation (1/3)x + 3y = 10.

a) The median would be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers.

a) The median is expected to be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean. The mean is calculated by adding all the values together and dividing by the number of values, and if there are any values that are much lower or higher than the rest, this will affect the mean significantly. The median, however, is the midpoint of the values, so outliers have less of an influence on it.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers. The median is the midpoint of the values, which means that if there are any values that are much lower or higher than the rest, it will not affect the median as much as it does the mean. This makes the median more accurate in representing the life expectancy of countries, as it is not skewed by outliers. Furthermore, the median is generally more reliable when dealing with skewed distributions, which is often the case with life expectancy data.

Step-by-step explanation:

Here's a possible implementation of the DivideByThree function in C:

int DivideByThree(int number) {

   int count = 0;

   while (number > 0) {

       if (number % 10 == 3) {

           count++;

       }

       number /= 10;

   }

   return count;

}

This function takes an integer number as input and returns the quotient of the division by 3 by counting how many times the number 3 appears in the original number. The function works as follows:

Initialize a counter variable count to 0.

While number is greater than 0, do the following:

a. If the last digit of number is 3 (i.e., number % 10 == 3), increment count.

b. Divide number by 10 to remove the last digit.

Return the final value of count.

For example, if we call DivideByThree(123456333), the function will count three occurrences of the digit 3 in the input number and return the value 1. If we call DivideByThree(33333), the function will count five occurrences of the digit 3 and return the value 1. If there are no occurrences of the digit 3 in the input number, the function will return 0.

Answer:

Step-by-step explanation:

True.

Aldosterone is a hormone produced by the adrenal gland that plays an important role in regulating electrolyte and water balance in the body. It acts on the cells of the distal tubules and collecting ducts of the kidneys to increase the reabsorption of sodium ions and the secretion of potassium ions.

This helps to increase blood volume and blood pressure by retaining more sodium and water in the body while getting rid of excess potassium. Aldosterone release is regulated by the renin-angiotensin-aldosterone system, which is activated in response to low blood pressure or low sodium levels in the blood.
