The equation that describes the relationship between money received and number of days is y = \(\frac{65}{2}x\) + 250

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. Here, x is a variable, A is a coefficient and B is constant.

from the table above when x = 2, y = 315 and when x = 4 y =380

equation of straight line or linear equation, y = mx + c

So we look for the values of the constants m and c

315 = 2m + c--------------------1

380 = 4m = c ------------------2

subtract equation 1 from 2

2m = 65

m = 65/2

substitute m in equation 1

2( 65/2) + c = 315

65 + c = 315

c = 315 - 65

c = 250

Equation becomes  y = \(\frac{65}{2}x\) + 250

In conclusion the linear equation for the relationship between x and y is  y = \(\frac{65}{2}x\) + 250

I'll use a cake for explanation.

Suppose we have a cake, and one of your companions, Mary, is hungry, so she takes 2/5 of one cake. Then, your other friend, Bella, takes 4/5 of the cake.

Then you compare the cakes. Who has less, Mary or Bella?

That's right, Mary.

So 2/5 is less than 4/5.

Answer:

  y = 1/3x +3

Step-by-step explanation:

Here, it will be convenient to write the equation in "slope-intercept form." That looks like ...

  y = mx +b . . . . . line with slope m and y-intercept b

__

The y-intercept is the y-value where the line crosses the y-axis. On your graph, there is a point there: (0, 3). That means the y-intercept is b=3.

The slope is the "rise" divided by the "run". The points on your graph are 3 units apart horizontally (run = 3). The point on the right is 1 unit above the point to its left (rise = 1). This means the slope of the line is ...

  m = rise/run = 1/3

Now, you have what you need to write the equation:

  y = 1/3x +3

Answer:

  2.5%

Step-by-step explanation:

You want the percentage below 335 if the distribution is normal with a mean of 555 and a standard deviation of 110, using the empirical rule.

The z-score of 335 is ...

  Z = (X -µ)/σ

  Z = (335 -555)/110 = -220/110 = -2

The empirical rule tells you that 95% of the distribution is between Z = -2 and Z = 2. That is, 5% of the distribution is evenly split between the tails Z < -2 and Z > 2. Half that value is in each tail.

  P(X < 335) = 5%/2 = 2.5%

The percentage of people taking the test who score below 335 is 2.5%.

Answer:

\(\frac{64}{125} \)

Step-by-step explanation:

\(0.512 = \frac{512}{1000} \\ = \frac{128}{250} \\ = \frac{64}{125} \)

The equation for calculating exponential decay is expressed as

A = Aox^t/T

where

A is the final amount after t years

Ao is the initial amount

x is the rate of change

t is the number of years

T is the time taken to achieve the change.

From the information given,

A = 2

t = 47 years

x = 1/2 = 0.5

T = 20

We want to find Ao

By substituting these values into the formula,

2 = Ao(0.5)^(47/20)

2 = Ao(0.5)^2.35

Dividing both sides by (0.5)^2.35, we have

Ao = 2/(0.5)^2.35

Ao = 10.2

the density of the substance when it was deposited 47 years ago is 10.2 milligrams per square centimeter

According to the information we can infer that the period of the graph is 8.

To determine the period of the graph we have to consider that the period of a grah is the distance between rigdes. So, in this case we have to count what is the difference between each rigde.

In this case, the distance between rigdes is 8 units because the first is located in the line 1 an the second is located in the line 9. So we can conclude that the period of the graph is 8.

Step-by-step explanation:

To rewrite the expression -2(n-7) using the distributive property, we need to distribute the -2 to both terms inside the parentheses. The distributive property states that for any numbers a, b, and c:

a(b + c) = ab + ac

Applying this property to the given expression:

-2(n-7) = -2 * n + (-2) * (-7)

Simplifying further:

-2(n-7) = -2n + 14

Therefore, the rewritten expression is -2n + 14.

The point where the two lines intersect represents the result to the system, which is n = 7.

An equation is a fine formula created by joining two expressions with an equal sign. 3x- 5 = 16 is the formula explanation. working this equation reveals that the value of the variable x is 7.

Let the equation for the total cost, c, of renting a canoe on River Y for n hours

c( Y) = 47

The equation for the total cost, c, of renting a canoe on River Z for n hours can be represented as follows

c( Z) = 5n 12

To find how numerous hours you have to rent a canoe for the cost to be the same on both gutters, we need to set c( Y) = c( Z) and break for n

= 5n + 12

35 = 5n

n = 7

Thus, if you rent a canoe for 7 hours, the cost will be the same on both gutters.

To graph the system, we can compass the two equations on the same graph, where the x-axis represents the number of hours and the y- axis represents the total cost

Graph of c( Y) = 47 and c( Z) = 5n + 12

Graph of c( Y) = 47 and c( Z) = 5n + 12

The point where the two lines intersect represents the result to the system, which is n = 7.

The graph formed will be as follows

The time taken to drain 23 liter at the rate of 2.5 liters per minute=9 minutes.

A cistern is a tank used to hold liquids, usually water, and it contains inlet and outlet pipes so it can fill up or empty itself. A pipe is a segment of a hollow cylindrical object used to transport water from one location to another. The cistern or tank typically has pipes attached to it so that they may be filled and emptied. Part of the tank evacuated in an hour is equal to 1/y if it takes y hours to completely empty it. If a pipe can completely fill and drain a tank in x and y hours, respectively. The net portion of the tank will be filled in one hour when both pipes are opened simultaneously, assuming y>x, by the formula (xy) = (xy) / (y-x).

70 liters of water were initially present in a water tank.

2.5 liters of water were drained every minute.

The tank holds 47 liters before water is added, thus 70-47 =23 liters.

Therefore,23/2.5=9.2 is the time it takes to drain 23 liters at the rate of 2.5 liters per minute.

Taking 2.5 liters per minute to fill a 23liter container takes 9.2minutes.

Water filled in a certain amount of time is equal to the water filling rate in minutes.

The profit function for a furniture company introducing a new line of lounge chairs is P(x) =\(-8.32x^2 + 1,248x - 36,400\), where x represents the number of chairs to be manufactured and sold.

The problem provides the revenue function and cost function for a furniture company introducing a new line of lounge chairs. To find the profit function, we need to subtract the cost function from the revenue function.

The revenue function R(x) is given as 1,248x - \(8.32x^2\), where x represents the number of chairs manufactured and sold. This function calculates the total revenue obtained by the company by multiplying the number of chairs sold (x) by the price of each chair (1,248 - 8.32x).

The cost function C(x) is given as 36,400 - 83.2x. This function calculates the total cost incurred by the company to manufacture x chairs, which includes both fixed and variable costs.

To find the profit function for the furniture company, we need to subtract the cost function C(x) from the revenue function R(x):

P(x) = R(x) - C(x) = (1,248x - \(8.32x^2\)) - (36,400 - 83.2x)

Simplifying this expression, we get:

P(x) =\(-8.32x^2\) + 1,248x - 36,400

Therefore, the profit function for the furniture company is P(x) = \(-8.32x^2\) \(+ 1,248x - 36,400\).
