Step-by-step explanation:
Jerry walked a dog from 6:40 am to 7:30 pm one day. If he was paid at the rate of 6$ per hour, how much did he earn that day?
Answer:
$5
Explanation:
Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.
Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.
660=x50
From here, you have to solve for x. So cross multiply, and then simplify.
60x=50⋅6
60x60=50⋅6/60
60x60=50⋅6/60
x=5⋅6/6
x=5
So the answer is $5.
Jerry earned about $76.98 for the day.
Jerry walked a dog from 6:40 am to 7:30 pm. To calculate how much he earned, we need to determine the total number of hours he worked.
First, we convert the end time into military time, which is 19:30.
Subtract the start time, 6:40, from the end time, 19:30.
Calculation:
From 6:40 am to 6:40 pm is 12 hours.From 6:40 pm to 7:30 pm is an additional 50 minutes, which is [tex]\frac{50}{60}[/tex] hours or approximately 0.83 hours.Total hours worked: 12 + 0.83 = 12.83 hours.Now, we use the rate of $6 per hour to calculate his earnings:
Earnings = Total hours * Rate per hour
Earnings = 12.83 hours * $6/hour = $76.98
Since Jerry worked a fraction of an hour, we included the approximate earnings up to two decimal places.
So, Jerry earned about $76.98 for the day.
If two figures are similar, the corresponding sides are?
The corresponding sides of similar figures can be equal, but if they are different in any way, they will always be proportional.
Corresponding angles, however, will always be equal.
If two figures are similar , the corresponding sides are proportional.
What are similar figures?Similar figures mean when two figures are of the same shape but are of different sizes. In other words, two figures are called similar.
They will have thesame shape , if possible thesame corresponding angles. But different sides. The ratio of the corresponding sides are equal or we can say that the corresponding sides are proportional.
This ratio of the sides is called scale factor.
Scale factor is expressed as;
scale factor = New dimension /old dimension.

Kathy organised a wedding , guests had to choose their meal from pasta , chicken or beef 1/3 chose pasta 5/12 chose chicken and 24 guests chose beef how many guests were at the wedding ?
so together the amount of people who chose beef should be 4/12 since you must find the greatest commen factor. Then you should add 4/12 and 24 im thinking and you would get 24.3333 but if your looking for a mix number it would be 24 3333/1000
hope this helps!
The question is a math problem involving the sum of fractions reflecting food choices at a wedding. By considering fractions and its equivalent counts, we find that the total number of guests at the wedding was 96.
Explanation:The subject of this question is mathematics, specifically a problem dealing with fractions. To determine the total number of guests at the wedding, we need to consider all the meal choices and their counts. 1/3 of the guests chose pasta and 5/12 of them chose chicken. The rest, as given, were 24 guests who chose beef. To find the total, we need to convert fractions to a common denominator. In this case, 12 is a convenient choice:
Pasta: 1/3 = 4/12
Chicken: 5/12
So, 4/12 + 5/12 = 9/12 of the guests chose either pasta or chicken. Since the remaining guests chose beef, that means 24 guests represent the remaining 3/12 of the total guests. Therefore, if 3/12 of the guests is 24, one 'part' (1/12) is equal to 24/3, which is 8. That means the total number of guests (12 parts) is 12 * 8, which equals 96. Therefore, there were 96 guests at the wedding.

3^1. 3
3^2. 9
A. add 3 to the previous value
B. subtract 3 from the previous value
C. divide the previous value by 3
D. multiply the previous value by 3
Answer:
D. multiply the previous value by 3
Step-by-step explanation:
The pattern of values as the exponents increase is
1/3, 1, 3, 9
Comparing 1/3 to 1, we either add 2/3 or multiply by 3.
Comparing 1 to 3, we either add 2 or multiply by 3.
Comparing 3 to 9, we either add 6 or multiply by 3.
The constant in this pattern is multiplication by 3.
Which system of equations is satisfied by the solution shown in the graph?
A. x + 2y = 6 and x − y = 10
B. x + y = 6 and x − 2y = 10
C. x + 2y = 10 and x − y = 6
D. x + y = 6 and x − y = -10
In order to find correct system for the given graph, we need to find the slopes and y-intercepts of the lines in shown graph.
For red line we have y-intercept = 10 because it is cutting y-axis at 10.
And slope of the red line is rise/run = 1/1 that is 1.
Using slope-intercept form y=mx+b
The equation of red line is y=1x +10 or x-y =-10.
For black line we have y-intercept = 6 and slope is rise/run = -1/1 = -1.
The equation of black line is y = -1x + 6 or x+y=6.
Therefore, correct option is D. x + y = 6 and x − y = -10.The solution shown in the graph satisfies the system of equations x + y = 6 and x - y = -10. The correct option is D.
The correct system of equations satisfied by the solution shown in the graph is x + y = 6 and x - y = -10.
To verify this, we can substitute the x and y values from any point on the graph into these equations.
If the values satisfy both equations, then the system is correct.
For example, let's take the point (2, 4) on the graph. If we substitute x = 2 and y = 4 into the equations, we get:
x + y = 6: 2 + 4 = 6, which is true
x - y = -10: 2 - 4 = -10, which is also true
Since both equations are satisfied by the point (2, 4), the correct system of equations is x + y = 6 and x - y = -10.
Therefor the correct option is D.

Mario's Fine Dining charges $60.22 for its prix fixe meal plus $37.69 for every drink, d, you purchase. The equation that models the total cost (T) isT(d)=37.69d+60.22. Which value in the equation represents the rate of change?
Answer:
The value of rate of change in the equation [tex]T(d)=37.69d+60.22[/tex] is 37.69.
Step-by-step explanation:
Given the equation that models the total cost(T) is:
[tex]T(d)=37.69d+60.22[/tex] where d is the drink you purchase.
To determine the rate of change:
1. An equation must be into the Slope-intercept form (y=mx+b).
2. m is the slope (rate of change) of the linear function.
3. b is the y-intercept of the linear function (y- intercept is where the line crosses the y-axis).
Since, the given equation is in the linear form i.e, [tex]T(d)=37.69d+60.22[/tex]
The rate of change(m) of the given equation is, 37.69.

Find the Distributive Property
8X46=8X(40+
Hey There!
8x^46=8x(40+
We move all terms to the left:
8x^46-(8x(40+)=0
The Distributive Property of multiplication, a fundamental concept in mathematics, was used to show that 8 x 46 = 8 x (40 + 6), which simplifies to 320 + 48 = 368.
Explanation:
The question is asking you to use the Distributive Property of multiplication, a rule in arithmetic that states that the product of a number and a sum, i.e., a(b + c), is equal to the sum of the products of that number and each term in the sum, i.e., ab + ac.
In this case,
8. x 46 = 8 x (40 + 6)
Using the Distributive Property, you would multiply the 8 by each term in the parentheses:
8 x 40 + 8 x 6.
This equals 320 + 48, which simplifies to 368. Hence 8 x 46 indeed equals 368, demonstrating the Distributive Property.

microeconomics chapter 7
That's a good chapter!
Microeconomics explores the actions of individual agents within the economy, focusing on consumer behavior, production costs, and market structures. It discusses the reasons behind individuals' and firms' decision-making processes, emphasizing the importance of markets and the role of government intervention.
Explanation:Understanding Microeconomics
Microeconomics is a branch of economics focused on the actions of individual agents within the economy, such as households, workers, and business firms. It dives into the fundamentals of consumer behavior, production and costs, and various market structures, including some aspects of game theory. The theory of the consumer and the theory of the firm are central to microeconomics, explaining how individuals and firms make decisions about what goods to buy or produce, and at what prices.
In microeconomics, key themes include individuals responding to incentives, the importance of markets in facilitating interactions among firms and households, and the role of government intervention. Chapters 5 through 10 cover the theories of consumer behavior, production and costs, and different market structures. Subsequent chapters delve into applied microeconomic policy issues like public goods, externalities, competition and antitrust policies, environmental challenges, poverty, and income inequality, among others. This comprehensive approach helps students understand not only the theoretical underpinnings but also the application of economic theory in addressing real-world issues.
