Answer:

The correct option is;

C. 3.25 + 5.50·S ≤ 30

Step-by-step explanation:

The given parameters are;

The cost of the chocolate milk ordered = $3.25

The unit quantity of pancake sales = Stack

The number of pancakes in a stack = 4

The amount a stack of four pancakes is sold = $5.50

The number of pancakes Benjamin wants to buy = As many as he can

The number of stacks of pancakes Benjamin buys = S

The cost of the pancakes Benjamin buys = $5.5 × S

The cost of the number of pancakes Benjamin buys

The maximum amount Benjamin wants his bill to amount to = $30

Therefore we have;

The cost of chocolate milk ordered + The cost of pancakes Benjamin buys  ≤ $30

Which gives;

$3.25 + $5.50 × S  ≤ $30

Therefore, the correct option is 3.25 + 5.50·S ≤ 30.

The solution to the system of equations y = 1.5x - 4 and y = -x  is (1.6,-1.6). The correct answer is D.

The solution to the system of equations can be calculate as follows

From the question we can conclude that the equations are :

y = 1.5x - 4

y = -x

to find the value of x and y  we can substitute y = -x in the first equation so it became

-x = 1.5x - 4

-1.5x - x = -4

-2.5x = -4

x = 1.6

after we found the value of x we can find the value of y by Substitute

x = 1.6 in y = -x

y = -1.6

Therefore, the solution to the y = 1.5x - 4 and y = -x  is (1.6,-1.6).

The temperature on mountaintop was -10° and the temperature on the ground was 10°. The solution has been obtained by using the linear equation.

What is a linear equation?

One is the degree of the linear equation. It is obvious that there are no variables in linear equations with exponents greater than 1. The graph's equation results in a straight line.

We are given that the temperature on the mountaintop was 20° lower than temperature on the ground.

Let the temperature on the ground be 'x'.

So, temperature on the mountaintop = x - 20

Also, the temperature on a mountaintop and the temperature on the ground had opposite values.

So,

x = - (x - 20)

On solving this, we get

⇒x = -x + 20

⇒2x = 20

⇒x = 10°

So, x - 20 = 10 - 20 = -10°

Hence, the temperature on mountaintop was -10° and the temperature on the ground was 10°.

a) Tanisha spent $15,000 to buy the car.

b) The rate of change of Tanisha's car over time is $1,250 per year.

c) A possible equation to represent the relationship between the value of Peter's car, V, in dollars, and time, t, in years is V = -1,250t + C, where C is the initial value of Peter's car.

d) The graph for Anna's car value over time would be a parallel line to Tanisha's line, passing through the point (5, 15,000).

e) The equation representing Anna's car value over time is V = -1,250t + 21,250, and her car will be worth $4,000 in approximately 15.8 years.

a) To determine how much Tanisha spent to buy the car, we need to find the initial value or y-intercept of the graph.

This represents the value of the car at time t = 0.

By looking at the graph, we can see that the y-intercept is at $15,000.

Therefore, Tanisha spent $15,000 to buy the car.

b) The rate of change of Tanisha's car over time can be determined by finding the slope of the line on the graph.

We can select two points on the line, such as (0, 15,000) and (4, 10,000), and use the slope formula:

Rate of change = (change in value) / (change in time) = (10,000 - 15,000) / (4 - 0) = -5,000 / 4 = -1,250

The rate of change of Tanisha's car over time is -1,250 dollars per year.

c) Since Peter's car costs less than Tanisha's and the value of both cars changes at the same rate, we can represent the relationship between the value of Peter's car, V, in dollars, and time, t, in years with the equation:

V = -1,250t + C

Where C represents the initial value or y-intercept of Peter's car.

The initial value of Peter's car can be different from Tanisha's car but less than Tanisha's initial value.

d) To draw Anna's car value over time on the same graph, we know that her car is worth the same as Tanisha's car in 5 years. So, the point (5, 15,000) should lie on Anna's graph.

The graph of Anna's car value over time would be a parallel line to Tanisha's line, passing through the point (5, 15,000).

e) To find an equation representing Anna's car value over time, we can use the slope-intercept form of a linear equation: y = mx + b, where y represents the car value, x represents time, m represents the rate of change, and b represents the initial value.

Since Anna's car is worth the same as Tanisha's in 5 years, the equation would be:

V = -1,250t + C

To find when Anna's car will be worth $4,000, we can substitute V = 4,000 into the equation and solve for t:

4,000 = -1,250t + C

Without the value of C, we cannot determine the exact time when Anna's car will be worth $4,000.

However, by knowing the value of C, we can substitute it into the equation and solve for t.

Answer:fixed ratio

Step-by-step explanation: :)

This is an illustration of a fixed ratio reinforcement schedule: after a predetermined number of responses, Frances is given a reward (in this case, $1). (every pound of worms).

An example of a reinforcement plan utilized in the behavioral psychology concept of operant conditioning is a fixed ratio reinforcement schedule. A reward or reinforcement is delivered according to this schedule after a predetermined number of actions or responses. As an illustration, a rat might receive a food pellet after every 10 lever presses.

Fixed ratio schedules work well for encouraging high response rates since the subject is driven to keep up the activity in order to earn the reward. Yet, if the reinforcement is stopped, the behavior can become less frequent or cease entirely.

Fixed ratio schedules can also cause behaviors to become rigid or stereotyped because the subject may start concentrating only on the number of responses required to earn the reward and stop considering other options or actions.

Overall, fixed ratio reinforcement regimens can be helpful in teaching both humans and animals to carry out particular tasks, but they should be utilized with caution and consideration for any unexpected consequences.

Answer:

m∠D = 49°
m∠E = 41°
m∠F = 90°

Step-by-step explanation:

        We know a triangle's angles add up to 180, so we can create an equation and solve for x. We also know the little box represents 90 degrees.

Given:

        90° + 5x° + 14° + 3x° + 20° = 180°

Combine like terms:

        8x° + 124° = 180°

Subtract 124 from both sides of the equation:

        8x° = 56°

Divide both sides of the equation by 8:

        x = 7

        Now, we will plug this value of x back into the angles to solve. Again, the little box represents that Angle F is equal to 90 degrees.

m∠D = 5x° + 14° = 5(7)° + 14° = 49°
m∠E = 3x° + 20° = 3(7)° + 20° = 41°
m∠F = 90°

Step-by-step explanation:

The minimum admission score is at the 70th percentile of the normal distribution which, according to a z-score table, corresponds to a z-score of 0.524.

The z-score, for any given value X, is determined by:

\(z=\frac{X-\mu}{\sigma}\)

If the mean score is 21 and the standard distribution is 6.2, the minimum required score for admission is:

\(0.524=\frac{X-21}{6.2}\\X=24.25\)

The minimum score required for admission is 24.25.

The diameter of a human hair is 7 times greater than the diameter of a spider's silk.

To determine how much greater the diameter of a human hair is than the diameter of a spider's silk, we can calculate the difference between the two diameters. The diameter of a human hair is given as 10^(-5) meters, and the diameter of a spider's silk is given as 3*10^(-6) meters.

To find the difference, we subtract the diameter of the spider's silk from the diameter of the human hair:

Difference = (10^(-5)) - (3*10^(-6))

= (10^(-5)) - (10^(-6))

= (10^(-5)) - (1/10^6)

= (10^(-5)) - (10^6/10^6)

= (10^(-5)) - (10^6 * 10^(-6))

= (10^(-5)) - (10^(6-6))

= (10^(-5)) - (10^(0))

= (10^(-5)) - 1

= 10^(-5) - 1

= 0.99999

Therefore, the diameter of a human hair is approximately 7 times greater than the diameter of a spider's silk.
