If Ruby has $10 and Max had $250 who has the most money?

Answer:

Step-by-step explanation:

The original amount there should be:

20 x 25 = 500

Take the extra 5 chairs and subtract it from the original amount, 500.

500 - 5 = 495  

Therefore, the amount of chairs that got set up would be 495.

2 + 2 = 4 because 4 is a sum of 1-digit numbers

2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers

Step-by-step explanation:

Lets explain some important notes:

∵ 2 + 2 is the addition problem of two 1-digit numbers

∴ There sum will be 4 which is also 1-digit number

∴ 2 + 2 must be 4

∵ 22 is a two digit number

∴ Its value is 20 + 2 ⇒ not 2 + 2

∴ 2 + 2 can not be 22

2 + 2 = 4 because 4 is a sum of 1-digit numbers

2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers

Answer:

The solution of the system of equations is the point (1,2)

Step-by-step explanation:

It is required to solve the system of equations:

y= -3x + 5

5x - 4y = -3

So, substitute with y from the first equation at the second equation:

∴ 5x - 4(-3x + 5) = -3

Solve for x

∴ 5x + 12x - 20 = -3

∴ 17x = -3 +20 = 17

∴ x = 17/17 = 1

∴ y = -3 * 1 + 5 = -3 + 5 =2

Total number on the trip is 24

Let the number of girls be x

Then the boys are x + 8

So... x + x + 8 = 24

2x + 8 = 24.......... This is the equation

2x = 24 - 8

2x = 16

x = 16/2

x = 8

Number of girls = 8

And number of boys = x + 8

Which is = 8+8 = 16

There were 8 girls and 16 boys on the trip.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Bradley and 23 of his classmates went on a trip to the aquarium.

∴ There are a total of 24 students.

There are 8 more boys than girls on the trip.

Assuming the no.of girls to be x, hence no. of boys is (x + 8).

So, x + (x + 8) = 24.

2x + 8 = 24.

2x = 16.

x = 8.

So, no. of girls on the trip is 8, and no. of boys on the trip is (8 + 8) = 16.

Final answer:

The volleyball court is 16 meters long, which was calculated by using the formula for the perimeter of a rectangle and the given width of 9 meters.

Explanation:

To find the length of the volleyball court, we need to use the formula for the perimeter of a rectangle which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Since we know the perimeter is 50 meters and the width is 9 meters, we can substitute these values into the formula to solve for the length l.

First, we calculate the total contribution of the width to the perimeter, which is 2w, so 2 times 9 meters = 18 meters. We then subtract this from the total perimeter to find the combined contribution of both lengths: 50 meters - 18 meters = 32 meters. Finally, we divide by 2 to find the length of one side: 32 meters / 2 = 16 meters.

Therefore, the volleyball court is 16 meters long.

I have attached a graph of such a system. The two lines have the same slopes but different y-intercepts, this means the lines are parallel, and therefore the system of equations that they represent  has no solutions because the lines never intersect.

Going into your next question, there are three ways the system of equations can be classified: the ones that have a solution, with infinitely many solutions, with no solutions.

The graphs of the system of equations that have a solution intersect exactly at one point.

The graphs of the system of equations that have infinitely many solutions are mapped onto each other (are on top of each-other), and therefore have infinite points of intersection.

The graphs of the system of equations that have no solutions never intersect;  these are represented by lines that are parallel.

The number of cookies baked by Glen alone = x = 16 cookies

The number of cookies baked by Alice alone = y = 32 cookies

Let the number of cookies baked by both together = z cookies

Now, According to question

Number of cookies baked by both together = number of cookies baked by Glen alone + number of cookies baked by Alice alone

Or, [tex]\dfrac{1}{z}[/tex] = [tex]\dfrac{1}{x}[/tex] + [tex]\dfrac{1}{y}[/tex]

Or,  [tex]\dfrac{1}{z}[/tex] = [tex]\dfrac{1}{16}[/tex] + [tex]\dfrac{1}{32}[/tex]

Taking LCM

[tex]\dfrac{1}{z}[/tex] = [tex]\dfrac{2 + 1}{32}[/tex]

Or,  [tex]\dfrac{1}{z}[/tex] = [tex]\frac{3}{32}[/tex]

Or, z = [tex]\dfrac{32}{3}[/tex]

Answer:

Proportional: Mike, a plumber charges $5 per hour for his service.

Non-proportional: Mike charges a initial cost of $10 plus $3 for each hours of service.

Step-by-step explanation:

Let us assume that Mike, a plumber charges $5 per hour for his service.

So, the number of hours (h) of service and the total charge (C) are proportional, which is  

C(h) = 5h ....... (1)

If the condition changes like, Mike charges an initial cost of $10 plus $3 for each hour of service.

Here, the equation that models the situation is  

C(h) = 10 + 3h .......... (2)

Now, relation (1) is non-proportional.  (Answer)

Final answer:

Real-world examples of directly proportional relationships include the relationship between distance and time at a constant speed, and cost and weight of fruit. These relationships become nonproportional when a base charge or flat fee is introduced, respectively.

Explanation:

Two real-world quantities that have a proportional linear relationship are speed and distance traveled in a given amount of time, assuming constant speed. For example, the farther you travel at a steady speed, the longer it takes. This relationship can be represented by y = kx, where y is the distance, x is the time, and k is the constant speed.

To make this relationship nonproportional, we could introduce a starting fee or base charge, making the total cost not just dependent on the distance but also an additional amount. Another example of a directly proportional relationship is the cost of fruit, where cost and weight are proportional (y = kx). By adding a flat packaging charge regardless of weight, the relationship between cost and weight becomes nonproportional.
