The number line that models the total amount of time Ava will practice piano in all is shown in the figure and  Ava will practice piano for a total of 6 hours.

We can model the total amount of time Ava will practice piano in all using a number line. Since she practiced for 3 hours yesterday and is going to practice for another 3 hours today, we can represent this on a number line as follows:

The number line above represents the total amount of time Ava will practice piano in all. The first mark (0) represents the starting point, which is when she has not started practicing yet. The second mark (3) represents the time she spent practicing yesterday, and the third mark (6) represents the time she will spend practicing today. The distance between the first mark and the third mark (0 to 6) is the total amount of time Ava will practice piano in all, which is 6 hours.

Using additional ink that is not necessary to convey information reduces the data-ink ratio, which should be maximized in order to effectively convey essential information in a table or chart.

Using additional ink that is not necessary to convey information reduces the data-ink ratio. The goal of maximizing the data-ink ratio is to ensure that the ink used in the visual representation of data is used only to convey the necessary information, without cluttering or distracting from the main message.

When unnecessary ink is used, it increases the amount of ink used overall, reducing the proportion of ink used for conveying information, and thus reducing the data-ink ratio. Therefore, to maximize the effectiveness of a table or chart, it's important to minimize the use of non-data ink and focus on the essential information.

Answer:

It will take 26.88hours to get to the beach

Step-by-step explanation:

From the problem statement, we are asked to find the time required to reach the beach.

given data

distance s=1344 miles

speed v= 50 mph

time t=?

we know that the relationship between speed, distance and time is given as

velocity=distance/time

substituting our given data into the expression we have

50=1344/t

making t subject of the formula we have

t=1344/50

t= 26.88 hours

Therefore it will take 26.88hours to get to the beach

A function is a mathematical concept that links an input (usually denoted by the variable x) to an output (usually denoted by the variable y or f(x)) in a well-defined way. A function can be compared to a computer that processes inputs and outputs in accordance with rules or guidelines. Each input value (also known as the domain) in a function is connected to precisely one output value (also known as the range). For instance, the linear function f(x) = 2x multiplies the input value x by two to create the output value.

given

f(x) = -0.5x + 12

The supply role is also provided by:

g(x) = 0.5x + 2

We must put these two functions equal to one another and then solve for x to determine where these two functions intersect:

-0.5x + 12 = 0.5x + 2

By multiplying both parts by 0.5, we get:

12 = x + 2

x = 10

The position at which the supply and demand functions intersect is therefore (10, f(10)) or (10, g(10)). We can enter the value x = 10 into either of the following functions to obtain the appropriate y-coordinate:

f(10) = -0.5(10) + 12 = 7

g(10) = 0.5(10) + 2 = 7

Ken can change the oil in his car 8 times using 8 gallons of motor oil for the racing season and 2 gallons left from last season, given that he uses 5 quarts of oil for each change.

We can start by converting the 8 gallons of motor oil to quarts, since we're given that Ken uses 5 quarts of oil each time he changes the oil.

1 gallon is equal to 4 quarts, so

8 gallons x 4 quarts/gallon = 32 quarts

Ken also has 2 gallons left from last season, which is equal to

2 gallons x 4 quarts/gallon = 8 quarts

So, Ken has a total of 32 + 8 = 40 quarts of motor oil.

To find out how many times Ken can change the oil, we need to divide the total amount of motor oil by the amount of oil used for each change

40 quarts ÷ 5 quarts/change = 8 changes

Therefore, Ken can change the oil in his car 8 times.

The inequality is 3,080 + w <= 4500. and we have explained the possible weights of the fourth horse.

What is inequality?

Inequality is a mathematical statement that compares two values or expressions and shows the relationship between them. It is used to express that one value is either greater than, less than, greater than or equal to, or less than or equal to another value. Inequalities can be represented using symbols such as < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), ≠ (not equal to).

We know that Mr. Thornton has already loaded three horses into his trailer with the following weights: 890 pounds, 1250 pounds, and 940 pounds. To load a fourth horse, we need to know the total weight of the trailer and the horses.

Total weight of the trailer = 890 + 1250 + 940 = 3,080 pounds

The trailer can support no more than 4500 pounds, so we need to make sure that the total weight of the trailer and the fourth horse does not exceed 4500 pounds.

Therefore, we can write the inequality:

3,080 + w <= 4500

This inequality tells us that the total weight of the trailer and the fourth horse (3,080 + w) must be less than or equal to 4500 pounds.

To graph the solutions of this inequality on a number line, we can start by plotting point 4500 on the number line. Since the inequality contains the "less than or equal to" sign, we need to shade everything to the left of 4500, including 4500.

The solutions to this inequality are all possible weights of the fourth horse that would not cause the total weight of the trailer and the horses to exceed 4500 pounds. The solutions are all real numbers between 0 and 420.

It's worth mentioning that the solution set is an interval [0,420] and it includes 0, but not 420. It means that the horse can weight 0 pounds (which is not possible) but it can't weight 420 pounds since it would exceed the maximum weight that the trailer can support.

Hence, the inequality is 3,080 + w <= 4500. and we have explained the possible weights of the fourth horse.

Answer:

Step-by-step explanation:

a. The graph of the budget line would have hamburgers on the x-axis and bags of figs on the y-axis. b. the budget line equation represents Rachel's affordability based on her income and the prices of hamburgers and figs. Changes in prices, income, or additional resources can affect the slope, position, or rotation of the budget line on a graph.

a) Rachel's budget line equation can be written as follows:

Budget = (Price of Hamburger * Quantity of Hamburgers) + (Price of Figs * Quantity of Figs)

Since the price per hamburger is $3 and the price per bag of figs is $2, the equation becomes:

Budget = 3x + 2y

Where x represents the quantity of hamburgers and y represents the quantity of bags of figs. The graph of the budget line would have hamburgers on the x-axis and bags of figs on the y-axis.

b) If the price of figs increases to $3, the new budget line equation becomes:

Budget = 3x + 3y

The graph of the new budget line would show a steeper slope compared to the original budget line. This indicates that the relative price of figs has increased, making them relatively more expensive compared to hamburgers.

c) In this scenario, Rachel has an income of $50, the price per hamburger is $3, the price per bag of figs is $3, and she receives an additional $10 in cash from a friend. The new budget line equation can be written as:

Budget = (3x + 3y) + 10

The graph of the new budget line would shift upward parallel to the original budget line. The additional cash from Rachel's friend increases her purchasing power, allowing her to afford more hamburgers and/or bags of figs.

d) Now, Rachel's friend gives her a gift basket containing 3 free bags of figs. In this case, the budget line equation remains the same as in part c:

Budget = (3x + 3y) + 10

However, since Rachel receives 3 free bags of figs, she can allocate more of her budget towards purchasing hamburgers. This would cause the budget line to rotate outward from the y-intercept, resulting in a flatter slope. The new budget line would reflect Rachel's ability to purchase more hamburgers with the same income and price of figs.

In summary, the budget line equation represents Rachel's affordability based on her income and the prices of hamburgers and figs. Changes in prices, income, or additional resources can affect the slope, position, or rotation of the budget line on a graph.
