Ou work as a cashier for a grocery store and earn $5 per hour. you also mow lawns and earn $10 per hour. you want to earn at least $50 per week, but would like to work no more than 10 hours per week. which system of inequalities, along with y ≥ 0 and x ≥ 0, would you use to solve the real-world problem?

Answers

You have to do 50x times 10 per hour

The problem can be represented by two inequalities: one to ensure earning at least $50 per week (5x + 10y >= 50) and another to restrict working to no more than 10 hours per week (x + y <= 10), alongside x >= 0 and y >= 0 to indicate non-negative hours worked for each job.

To determine the system of inequalities to solve the problem, we need to define variables for the number of hours spent on each job. Let's use x to represent the number of hours working as a cashier at the grocery store, and y to represent the number of hours mowing lawns. The student earns $5 per hour at the grocery store and $10 per hour mowing lawns. They want to earn at least $50 per week and work no more than 10 hours in total.

From this information, we can establish the following inequalities:

5x + 10y >= 50 (To ensure earning at least $50 per week)

x + y = 10 (To ensure working no more than 10 hours per week)

Additionally, we include y >= 0 and x >= 0 to represent that the number of hours worked at either job cannot be negative.

A cooking group made 240 oz of spaghetti sauce to sell at a county fair. The group can pour the sauce into small jars that hold 8 oz and large jars that hold 16 oz. The group leader made a sketch to show the line representing the different combinations of jar sizes the group can use. The x-axis represented the number of small jars and the y-axis represented the number of large jars. The group leader labeled only the intercepts.

Which points did the group leader label?

(0, 8) and (16, 0)
(0, 30) and (15, 0)
(0, 15) and (30, 0)
(0, 16) and (8, 0)

Answers

*Given
Total amount of spaghetti sauce - 240 oz.
Small jar capacity - 8 oz
Large jar capacity - 16 oz

Points:
(0, 8) and (16, 0)
(0, 30) and (15, 0)
(0, 15) and (30, 0)
(0, 16) and (8, 0)

*Solution

The only points that would be labeled by the leader would be those points that would correspond to a total amount of 240 oz of spaghetti sauce. Thus, each point should be evaluated using the following expression:

8x + 16y    (EXPRESSION 1)
8x + 16y = 240 (EQUATION 1)

The expression and the equation was set up based on the condition that the x-axis corresponds to the number of small (8 oz) jars and the y-axis corresponds to the number of (16 oz) large jars.

Since pairs of intercepts are given, both points should be evaluated using the given expression and each of the results should give an answer of 240. Thus, Equation 1 must be satisfied.

Testing out each pair one by one:
1. (0,8) and (16,0)

8(0) + 16(8) = 128
8(16) + 16(0) = 128

This does not satisfy the condition set by Equation 1 because the result of the evaluation of each of the intercepts using Expression 1 is not 240. Therefore, these are not the intercepts of the line to be plotted.

2. (0,30) and (15,0)

   8(0) + 16(30) = 480
8(15) + 16(0) = 120

This does not satisfy the condition set by Equation 1 because the result of the evaluation of each of the intercepts using Expression 1 is not 240. Therefore, these are not the intercepts of the line to be plotted.

3. (0,15) and (30,0)

   8(0) + 16(15) = 240
8(30) + 16(0) = 240

This satisfies the condition set by Equation 1 as each of the intercepts, when evaluated using Expression 1, gives an answer of 240.

4. (0,16) and (8,0)

   8(0) + 16(16) = 256
8(8) + 16(0) = 64

This does not satisfy the condition set by Equation 1 because the result of the evaluation of each of the intercepts using Expression 1 is not 240. Therefore, these are not the intercepts of the line to be plotted.

Thus, the points that the leader will be plotting on the graph are the intercepts (0,15) and (30,0).

If a box measures 1.2m by 3.4m by 0.50m, what is its volume in liter

Answers

multiply the given dimensions by (100cm/1m) to convert it to centimeters

1.2(100cm/1m) = 120 cm
3.4(100cm/1m) = 340 cm
0.5(100cm/1m) = 50 cm

the volume of a box is equal to (length)(width)(height)

that is
V = (120cm)(340cm)(50cm)
V = (6000 cm^2)(340cm)
V = 2040000 cm^3

now 1 cm^3 is equal to one mL and 1000 mL is 1 Liter

V =2040000 mL multiply by (1 Liter/1000 mL)
V = 2040 L

That's 2,040 liters.

Hope this helps :)

Volume can be worked out by multiplying the width, length and height i.e.
1.2m * 3.4m * 0.5m = volume
2.04m^3 = volume

Now we need to convert that in liters
1 cubic meter = 1000 liters
So 2.04 cubic meters = 2040 liters

What is the height of an equilateral triangle with sides that are 12 cm long? Round to the nearest tenth. (1 point)

Answers

The height of an equilateral triangle can be found using the formula h = √3 / 2 × a. Therefore, when we plug in 12 for a, we get that the height of the equilateral triangle is 10.4 centimeters.

Answer:

10.4 cm

Step-by-step explanation:

Looking at the triangle in the attached pic, we can see that the right, smaller triangle is a right triangle on which we can apply the pythagorean theorem to solve for the height, h.

Pythagorean theorem tells us [tex]c^2=a^2+b^2[/tex] where c is the hypotenuse (12 in our case) and a & b are the two legs (6 and h are the respective lengths).

So let's solve for h:

There are many ways in which you can present numerical data. ... is the most appropriate depends upon the amount of data you are dealing with and their complexity. ... text should describe what the data reveal about the topic; you should not need to ... Numbers in tables should be presented in their most simple format.

The most appropriate format for representing data depends on the intended audience, data type, and presentation purpose. Adherence to professional formatting guidelines is critical, and while figures can make data accessible, they should not duplicate table data. The effectiveness of formats such as complete sentences, tweets, Prezi, and visual figures varies based on the context.

When choosing the most appropriate format for representing data, several factors need to be considered such as the intended audience, the type of data, and the purpose of the data presentation. Complete sentences, Prezi presentations, 140 character tweets, and drawn pictures each have their own strengths in conveying information effectively and engagingly depending on these factors.

For professional or academic reports, complete sentences and structured paragraphs provide in-depth analysis and explanation. However, for social media platforms, 140 character tweets can quickly capture attention and convey key points. A Prezi can be highly engaging and visually appealing for presentations, making complex information accessible. Conversely, when displaying detailed findings, sometimes a well-illustrated figure or a clear table can speak volumes more efficiently.

Nonetheless, adhering to formatting guidelines is crucial in a professional context, as non-compliance could lead to the rejection of the report. It's also important to note that while figures are useful for making data accessible, they should not duplicate data presented in tables. When using figures, they must be clearly titled, referenced in the text, and situated conveniently in the report. If the figures are too dense, they can be relegated to an appendix.

In summary, there is no one-size-fits-all format for data presentation. Preference may vary depending on personal comfort with certain formats or the requirements of a specific assignment. Reflecting on the exercise of presenting information in various formats can elucidate which is most effective for your specific needs and audience.

If 8 times a number is decreased by 20,the result is the same as 3 times the number increased by 80

Answers

Final answer:

The algebraic expression for the problem is '8n - 20 = 3n + 80', which simplifies to 'n = 20'. Therefore, the number in question is 20.

Explanation:

The question presents a classic algebra problem where we have to find the value of a variable that satisfies a given condition. Specifically, this problem states:

"If 8 times a number is decreased by 20, the result is the same as 3 times the number increased by 80."

To solve this, we'll convert the words into an algebraic equation and solve for the number. Let's use 'n' to represent the number:

8n - 20 = 3n + 80

This equation tells us that when you multiply the number by 8 and subtract 20, it's equal to the result of multiplying the number by 3 and adding 80. To find 'n', we combine like terms and solve:

8n - 3n = 80 + 205n = 100n = 100 / 5n = 20

Thus, the number we're looking for is 20.

The wedge makes a shape whose cross-section perpendicular to the x -axis at distance x from the origin is a triangle whose base is is given by: [tex]y=\sqrt{100-x^2}[/tex]

The height of the wedge is given by:

[tex]y\tan30^o= \frac{\sqrt{100-x^2}}{\sqrt{3}} [/tex]

Final answer:

The volume of the wedge is 50π/3 - 25√3.

Explanation:

To find the volume of the wedge, we need to calculate the volume of the cylindrical segment between the two intersecting planes. The formula for the volume of a cylindrical segment is V = h((R^2θ)/2 - (R^2sinθ)/2), where h is the height of the segment, R is the radius of the cylinder, and θ is the angle of the intersection between the planes. In this case, h is 10 and θ is 30°, so the formula becomes V = 10((10^2 * π/6)/2 - (10^2 * sin(π/6))/2). Simplifying the equation gives V = 50π/3 - 25√3.

For a craft project, two equilateral triangles are taped together to create a quadrilateral. What is the quadrilateral? rhombus rectangle trapezoid square

Answers

Rhombus! Hope this is correct i am 99% sure

Answer:- The quadrilateral must be a rhombus.

Explanation:-

Given :-For a craft project, two equilateral triangles are taped together to create a quadrilateral.

We know that an equilateral triangle is a triangle in which all the sides and angles are equal such that its each interior angle should be 60°.

If we join two equilateral triangle by to create a quadrilateral then the sides of the quadrilateral would be same as it was constructed by equilateral triangle.

Then the interior angle for the sides which are not joint will remain same as 60°.

But the interior angle for the vertex of quadrilateral which has formed by joining two triangles will become 60°+60°=120°.

Thus it is not a square , rectangle (no right angle )or trapezoid(quadrilateral have equal sides).

Therefore, the quadrilateral must be a rhombus.

You and your friend are selling raffle tickets for a new laptop. you sell 14 more then your friend sells. Together you and your friend sell 58 tickets. Write a system of linear equations that represent this situation. How many did each of you sell?

Answers

Final answer:

You sold 36 tickets and your friend sold 22 tickets.

Explanation:

Let's represent the number of tickets you sell as x and the number of tickets your friend sells as y.

We know that you sell 14 more tickets than your friend, so we have the equation:

x = y + 14

We also know that together you and your friend sell 58 tickets, so the equation becomes:

x + y = 58

Now we can solve these two equations simultaneously to find the values of x and y.

Substitute the value of x from the first equation into the second equation:

(y + 14) + y = 58

Combine like terms:

2y + 14 = 58

Subtract 14 from both sides to isolate the variable:

2y = 44

Divide both sides by 2 to solve for y:

y = 22

Now substitute the value of y back into one of the original equations to solve for x:

x = 22 + 14

Simplify:

x = 36

Therefore, you sold 36 tickets and your friend sold 22 tickets.

Final answer:

The system of equations representing the problem is y = x + 14 and x + y = 58. Solving this system we get x = 22 (friend's sold tickets) and y = 36 (your sold tickets).

Explanation:

We'll use a system of linear equations to model this situation. Let's define x as the number of tickets your friend sells, and y as the number of tickets you sell. From the problem, we know two things:

1. You sell 14 more tickets than your friend: y = x + 14.

2. Together, you and your friend sell 58 tickets: x + y = 58.

To solve this system, we can substitute y in the second equation with x + 14 from the first equation. This gives us:

x + (x + 14) = 58.

Solving this we get x = 22 and substituting x into the first equation gives: y = 22 + 14 = 36.

What is the equation of this line?

y = -3/2x

y = 2/3x

y = -2/3x

y = 3/2x

Answers

Answer: Choice B

The slope is rise/run = 2/3 meaning we go up 2 and over to the right 3. For instance, moving from (0,0) to (3,2) has us move up 2 and over to the right 3.

Alternatively you can use the slope formula m = (y2-y1)/(x2-x1) to get the same result of 2/3.

(-3,-2)(3,2)
so slope = (2 + 2)/(3+3) = 4/6 = 2/3
y = mx + b
b = y - mx
b = -2 - (2/3)(-3)
b = -2 + 2
b = 0

equation
y = 2/3x

answer
B. y = 2/3x

What is the slope below

Answers

Use the two given points and the slope formula

(3, -2) and (2, -4)

m = (y2 - y1)/(x2 - x1) = (-4 - (-2))/(2 - 3) (-4 + 2)/(-1) = -2/(-1) = 2

An auditorium is to seat 2,400 people. The building code requires three square feet for each person. How many square meters will that auditorium have?

Answers

Answer:
______________________________________
Explanation:
______________________________________
Method 1)

2,400 person (3 ft² / person) = __?__ m² .

The units of "person" ; 'cancel out"; since "person/ person" = 1 ; and 1/1 = 1.

and we have: "2,400 * (3 ft²) = 7, 200 ft² .
______________________________________
We are ask to find the value, in units of "m² " ;
______________________________________
→ So; we convert "7, 200 ft² " ; to "m² " ;
______________________________________
  → Note the conversion: 1 m² = 10.7639 ft² ;
______________________________________
  → 7, 200 ft² * [ ( 1m²) / ( 10.7639 ft²) ] ;

= [ (7, 200 ) / (10.7639 )] m² ;

= 668.9025353264151469 m² ;

⇒ Round to 668.903 m² .
______________________________________
Method 2)
______________________________________

2,400 person (3 ft² / person) = __?__ m² .

Since we want the answer is units of: "m² " ;
___________________________________________
Let us convert: "3 ft² " to units of: "m² " ; and then rewrite the problem.
___________________________________________
→ Note the conversion: 1 m² = 10.7639 ft² ;
___________________________________________
   = [ (7, 200 ) / (10.7639 )] m²

= 668.9025353264151469 m²

⇒ Round to 668.903 m² .
______________________________________
Method 3)
______________________________________
2,400 person (3 ft² / person) = __?__ m² .
______________________________________
→ Note the conversion: 1 m² = 10.7639 ft² ;
______________________________________
(2,400 person) * (3 ft² / person) * [ ( 1m²) / ( 10.7639 ft²) ] ;

= { [ (2,400) * (3) * (1) ] / [ 10.7639 ] } m² ;

= { [ (2,400) * (3) ] / [ 10.7639 ] } m² ; {Note: The "1" can be ignored.}.

= [ (7,200) / (10.7639) ] m² ;

= 668.9025353264151469 m² ;

  ⇒ Round to 668.903 m² .

An airplane traveling 245 m/s east experiences turbulence, so the pilot slows down to 230 m/s. It takes the pilot 7 seconds to slow down to this speed. What is the acceleration of the plane? Round your answer to the nearest hundredth.
2.14 m/s2
–2.14 m/s2
67.86 m/s2
–67.86 m/s2

Answers

I think the answer is B. -2.14 m/s2

Answer:

Acceleration, [tex]a=-2.14\ m/s^2[/tex]

Step-by-step explanation:

Initial speed of the airplane, u = 245 m/s

Final speed of the airplane, v = 230 m/s

The pilot takes 7 seconds to slow down to this speed. Let a is the acceleration of the plane. The change in velocity per unit time is called the acceleration of an object. It can be calculated as :

[tex]a=\dfrac{v-u}{t}[/tex]

[tex]a=\dfrac{230\ m/s-245\ m/s}{7\ s}[/tex]

[tex]a=-2.14\ m/s^2[/tex]

So, the acceleration of the plane is [tex]-2.14\ m/s^2[/tex]. Hence, the correct option is (b).
